The pronunciation in the laboratory is [shì yàn shì].
2. The meaning is different.
A laboratory is a place for experiments.
Laboratory is a system, including a series of instruments, materials and personnel related to the corresponding test, and it is the integration of a system.
3. The classification is different.
According to disciplines, laboratories can be divided into: biological laboratories, general biosafety protection laboratories and experimental vertebrate biosafety protection laboratories.
According to the classification, it can be divided into the following categories: the first category is the laboratory established in, affiliated with or entrusted by colleges and universities; The second category belongs to national institutions, and some even international institutions; The third category directly belongs to the industrial enterprise sector and serves the development and research of industrial technology.
The laboratory is divided into chemical experiments, physical experiments, biology and humanities according to disciplines.
Extended data
The national laboratory was established by the state with a direct investment of several hundred million yuan (for example, the Wuhan Optoelectronic National Laboratory built in the campus of China University of Science and Technology invested 480 million yuan).
There are only nine national laboratories (including Beijing Positive and Negative Ion Collision Base and Huazhong University of Science and Technology Optoelectronic National Laboratory). The national laboratory represents the highest level of the country and is established according to international first-class standards. The scale is very large, which basically includes all research directions in this field. Moreover, the staffing requirements require the recruitment of the best researchers at home and abroad to directly participate in international competition, which is often an interdisciplinary innovation platform.
The State Key Laboratory passed the national appraisal. After being identified, you can get more money from the country every year. There are hundreds of State Key Laboratories, and the research direction is relatively narrow.
The national laboratory and the national key laboratory are two completely different concepts, not a heavyweight, and five national key laboratories are not comparable to one national laboratory.
Laboratory instruments are collectively called testing machines, mainly tensile testing machines.
Testing machines are widely used. It can test the tensile strength, elongation, tear, adhesion, tensile stress, peeling, shear force, adhesion between rubber and metal, etc. of various materials and finished products such as soles, tires, hoses, triangle belts, plastic plates, plastic sheets, packaging films, acrylics, FRP, ABS, EVA and PV.
