2. The second category is group counseling based on sensitivity training. The purpose is to train how to deal with interpersonal relationships effectively, train life skills and improve social adaptability. Mainly for enterprises, government agencies, training managers, managers and students, based on learning, understanding and coordinating interpersonal relationships.
3. The third category is therapeutic group counseling, which pays more attention to subconscious problems. It is mainly aimed at those who are abnormal in their hearts and organized by consultants, with the aim of relieving symptoms and achieving mental health.
Biomedical materials can be roughly divided into three types: biomaterials are widely used, with many varieties and different classification methods. Generally, it is divided into: synthetic polymer materials (medical synthetic plastics and rubber such as polyurethane vinegar, poly-vinegar, polylactic acid, polyglycolic acid and lactic glycolic acid polymer). ), natural polymer materials (such as collagen, silk protein, cellulose, chitosan, etc. ), metals and alloy materials (such as metals and their alloys, etc.). ), inorganic materials (bioactive ceramics, hydroxyapatite, etc. ), and composite materials (such as. According to the use of materials, these materials can be divided into biologically inert materials, biologically active materials or biodegradable materials. These materials are used to repair and replace hard tissue and soft tissue respectively through long-term implantation, short-term implantation and surface repair. Biomedical materials have strict requirements for their use because they are directly used in human body or closely related to human health. First of all, biomedical materials should have good blood compatibility and tissue compatibility. Secondly, it is required to resist biological aging. That is, the biological stability of long-term implanted materials is better; For temporarily implanted materials, it is necessary to degrade into nontoxic monomers or fragments that can be absorbed or metabolized by the human body within a certain period of time. It also requires stable physical and mechanical properties, easy processing and molding, and appropriate price. Convenient disinfection and sterilization, non-toxic and heat-free, non-carcinogenic and non-teratogenic must also be considered. For materials with different uses, the requirements are different.
Adler's group counseling aims at creating a therapeutic relationship, encouraging members to explore the basic assumptions of life and have a broader understanding of lifestyle; Help visitors realize the strength and advantages of promoting change; Encourage tourists to take full responsibility for the lifestyle they choose and any changes they want to make.
Ci can be divided into three categories, also known as "poetry", "long and short sentences", "relying on sound" and "ci", which is a form of poetry, with the highest achievement in Song Dynasty. Words are divided into poems, middle tones and long tones, and are divided according to the number of words. The number of words in the whole poem is less than 58 words, 59-90 words are in alto, and the long sound is above 9 1 word.
The classification of psychological counseling, according to the consulting scale 1, individual counseling 2, group counseling psychological counseling is divided into individual counseling and group counseling according to the number of counseling objects.
Individual consultation is the most common form, with strong pertinence and more communication between the two sides;
The characteristics of group consultation are wide consultation range, high efficiency, and beneficial to the interaction between group members. The disadvantage is that it is difficult to simply consider the particularity of each individual (couples therapy and family therapy are also classified as group counseling).
What are three kinds of algae?
blue-green algae
Cyanobacteria are unicellular or filamentous prokaryotes, and their cells contain chlorophyll and cyanophycin. It adapts to a wide growth temperature, but grows best in warm seasons; The growth of cyanobacteria makes the water turn blue or other colors, giving off the smell of grass or mildew. Microcystis, Echinococcus and Houttuynia cordata in cyanobacteria can be used as indicators of water eutrophication.
Green algae
Green algae is a unicellular or multicellular eukaryote. Cells are mainly chlorophyll, which likes to grow on the surface of flowing and static water and soil, and often emits the smell of grass and fish. Green algae grow best in autumn. Chlorella and scenedesmus in green algae are rich in protein, which can be eaten by people and used as drinks.
diatom
It is unicellular or multicellular, shaped like a small box, consisting of an upper shell and a lower shell. Its cell wall contains a lot of silicon dioxide. Diatoms grow well in spring and autumn, and their cells are rich in carrot pigment and chlorophyll.
Other algae
Euglena has no cell wall and grows in still water or slow flowing water rich in organic matter, which is an indicator of eutrophication of water. Charophyta is a large individual, and its smell can be used to smoke and repel mosquitoes. Yellow algae mostly grow in fresh water; Dinoflagellate can grow in fresh water, brackish water and seawater. Chrysophyta thrives in fresh water in cold season, in which Chrysophyta can give off a strong smell and make water bitter, which is an important indicator of algae pollution in water supply sources.
Generally speaking, wood can be divided into hardwood, cork and mahogany.
There are many ways to classify wood. According to the specific situation of production and trade such as tree species, wood products, processing technology and uses, wood is classified with different classification marks from different angles. Common wood classification methods are as follows:
First, according to the classification of tree species, wood is a natural product from forests, and there are many kinds of trees. Wood of different tree species usually has different structures and properties, which determines the difference in use value. Therefore, the name of tree species is an important basis for evaluating wood quality and use value. The classification of wood species follows the classification standard of plant taxonomy, that is, it is classified according to the morphological characteristics and anatomical structure of flowers, fruits and leaves of trees. This classification is undoubtedly scientific and systematic, and can reflect the genetic relationship among tree species.
2. Plant classification of woody tree species: ① Unit of plant classification: Plant classification is based on the similarities and differences of external organs such as flowers, fruits, leaves, stems and roots, internal organizational structure and cell chromosomes. Scientifically revealed the subtle genetic relationship between plants and their evolutionary process. In this way, according to the law of natural occurrence and development of the plant kingdom, through comparison, analysis and induction, the genealogy of the plant kingdom is compiled, so that all kinds of plants with various names can find their own positions. The basic unit of plant classification is "species", the largest unit is "boundary", and the middle division unit is "phylum, class, order, family and genus". Families, genera and species are the most important units related to wood classification, and their basic concepts are:
Species have similar morphological characteristics, show certain biological characteristics and living conditions (natural distribution), can produce genetically similar offspring, and occupy the sum of countless individuals in a certain distribution area of nature. Such as ginkgo, Chinese fir, Fraxinus mandshurica, Populus tomentosa and so on.
Genus is a common and important level in biological taxonomy, which is composed of several closely related species, located between families and species, and there are obvious gaps or differences between genera.
Family is also a common level in biological taxonomy, which is composed of several genera with similar genetic relationship.
② Plant Classification Tree Species Name: The naming of tree species is an important part of plant classification. The common name of every plant in the world is called scientific name, which consists of Latin or other Latin languages. Each scientific name includes a generic name and a generic name, that is, the binomial method is adopted, and the generic name is followed by the name of the nominator. Capitalize the first letter of the genus name. For simplicity, people's surnames are often omitted. For example, the scientific name of Ginkgo biloba is the Latin spelling of "Yinguo" in China Cantonese dialect, and the name of Ginkgo biloba is Latin, which means two leaves. (3) Conifers and broad-leaved trees: among gymnosperms, only ginkgo, pine, fir and cypress belong to trees. Because the leaves of these trees are usually small and needle-shaped or needle-shaped, they are customarily called conifers, and the wood of conifers is called conifers. Cork is also called cork because it is generally light and soft. It is worth noting that not all cork materials are light and soft. Woody plants in angiosperms dicotyledonous plants are customarily called broad-leaved trees because of their wide leaves. The wood of broad-leaved trees is called hardwood; Because hardwood is hard and heavy, it is also called hardwood. There are also very light and soft hardwood. Because of the variety of hardwood, it is also called miscellaneous wood in practical application.
Second, the classification of timber types and commercial timber:
① Tree species names of wood: There are many kinds of wood names, which can be roughly divided into scientific names, China standard names, trade names and common names. Wood of the same tree species often has different names because of different regions. For example, the scientific name of Pinus massoniana is Pinus massoniana, the Chinese standard name is hardwood pine, and the common name is pine, clump tree, pine and pine.
The scientific name is the common name of each tree species, or Latin name. Because of its uniqueness, it has practical significance in scientific research and international trade. In timber trade (especially import and export business), the scientific name (Latin name) of timber tree species must be adopted. Because the scientific names of China standard names are spelled in Latin, they are restricted in the fields of wood production, trade and use. In China, every tree species should have a unified Chinese name, which corresponds to the scientific name one by one. This is the standard name of China. Trade names are widely used in the fields of wood production, trade and utilization. Also known as the name of commodity materials. Common name is an informal name and a popular name for wood species. It is often local, so it is also called local name.
(2) Commodity names of wood species: In the field of production, trade and utilization of wood commodities, it is not feasible to classify according to the standard names of each tree species. The main reason is that there are many kinds of wood, and many tree species belonging to the same family are very similar in appearance characteristics and materials. In the process of on-site wood inspection, it is impossible to determine tree species with naked eyes in most cases. Several tree species with similar appearance characteristics, wood structure and wood properties and similar use value are classified into one category, and a "commodity name" is defined, which is the classification of commodity tree species. For example, there are many Populus species in Salicaceae, and there is no obvious difference in the structural characteristics of their wood, and the materials are similar. Therefore, as commercial timber, their trade names are collectively called poplars. The same tree species has different names due to different places of origin; The same name is often referred to by different tree species because of different regions. This is very common in actual production. Therefore, the names of commercial timber must be unified, otherwise it will bring many difficulties to the production, trade and scientific research of commercial timber, cause confusion in the circulation of timber market and hinder the rational utilization of timber. China has standardized the main domestic wood varieties, and formulated the national standard GB/T 16734- 1997 "Wood as China". National standard GB/T18513-2001
Thirdly, price classification by wood material is an important basis to reflect wood quality and use value. In order to facilitate the pricing of commodity materials by material classification in trade, commodity materials are often divided into several categories (such as five categories) on the basis of the above classification of commodity materials, which is the pricing classification of commodity materials. In the timber production department, the valuation classification of commercial timber is convenient for timber inspection, classification, management and cost accounting. The evaluation and classification of commercial timber are mainly based on the following principles: protecting precious tree species, reflecting high quality and good price, expanding alternative tree species, and advocating the development of promising fast-growing tree species. Classified pricing was widely implemented in the planned economy period, but it has been adopted in the market economy.
Four, according to the classification of wood species, all kinds of products belonging to the forest harvesting industry and wood mechanical processing board are called wood species. So wood classification refers to the classification according to the appearance, processing degree and supply requirements of wood products. Mainly divided into three categories: logs, sawn timber and wood-based panels. On this basis, it can be subdivided according to the use characteristics, processing methods, quality and specifications. (1) logs: logs are industrial products of forest harvesting, mainly including logs and logs. After the original trees are cut down, they are only trimmed and partially peeled, and there is no cross-cutting log product. Eucalyptus species, for example, are divided into Chinese fir original strips and masson pine original strips. The logs are cut horizontally according to certain length specifications, which conforms to the standard size of log segments. According to the purpose, there are direct logs (such as potholes, telephone poles, building sandalwood, etc. ), super logs (high-quality logs for advanced building decoration and special needs, with strict requirements on tree species, quality and specifications), logs for sawing, logs for rotary cutting, logs for rotary cutting veneer, logs for planing veneer, etc. (2) Sawn timber: sawn timber refers to the square timber with a certain cross-sectional size or cross-sectional size (four timber faces) sawed longitudinally from logs. Sawn timber is also called wood. According to tree species, cross-sectional shapes and uses, there are coniferous sawn timber, broad-leaved sawn timber, whole-edge sawn timber, raw-edge sawn timber, sleepers, railway wagon sawn timber, truck sawn timber and so on. (3) Wood-based panel: Wood-based panel (hereinafter referred to as wood-based panel) refers to the deep processing of wood and its processing or logging residues through a certain production process. According to the manufacturing process, it can be divided into plywood, fiberboard, particleboard and joinery board.

What are these three kinds of bacteria? According to its shape, it can be divided into cocci, bacilli and spirillus (including vibrio, spirillus and spirillus). According to the life style of bacteria, it can be divided into autotrophic bacteria and heterotrophic bacteria, among which heterotrophic bacteria include saprophytic bacteria and parasitic bacteria. According to the oxygen demand of bacteria, they can be divided into aerobic (complete aerobic and mild aerobic) and anaerobic (incomplete anaerobic, aerobic tolerant and complete anaerobic) bacteria. According to the survival temperature of bacteria, it can be divided into three categories: cold-loving, normal temperature and high temperature.
What are the three types of Han Fu? Han Fu is a rhyming prose that appeared in the Han Dynasty. It is characterized by the combination of prosody and rhyme, and is good at narration. From the form of fu, it lies in "transmitting and receiving"; As far as the content of Fu is concerned, the emphasis is on "writing things and writing ambitions". The content of Han Fu can be divided into five categories: one is to render Miyagi; The second is to describe the emperor hunting; The third is to describe the travel experience; The fourth is to express unsatisfied feelings; The fifth is about animals and plants. In the past, they were representatives of Han Fu.
Generally speaking, Han Fu has three parts in structure, namely preface, text and ending called "chaos" or "news". Most of the writing methods of Han Fu are flowery and gentle, praising the strength of the Han Empire or the civil and military style of the rulers, with only a few strokes at the end, which is slightly ironic and admonitory.
Han Fu can be divided into big Fu and small Fu. Da Fu, also known as Three-body Da Fu, has a huge scale, magnificent structure and magnificent vocabulary, and is often a huge system with thousands of words. Jia Yi, Mei Cheng, Sima Xiangru and Yang Xiong in the Western Han Dynasty, and Ban Gu and Zhang Heng in the Eastern Han Dynasty were all great fu writers. Xiaofu abandons the defects of long speech, flowery rhetoric, giving up the essentials and lacking emotion. On the basis of retaining the basic literary talent of Han Fu, they created short Fu, Zhao Yi Fu, Cai Yong Fu and lyric Fu.
