Second, use space technology to search data and analyze how it embodies the essence of technology, such as purpose, innovation, comprehensiveness, duality and patentability.
A: Definition: Space technology is a technology for exploring, developing and utilizing space, also known as space technology and aerospace technology.
Objective: The purpose is to use spacecraft as a means to study physical, chemical and biological natural phenomena occurring in space.
Innovation: Space technology is a fast and large-scale science and technology, which can play the most important role in the macro.
Comprehensive: Space technology is a highly comprehensive science and technology, and it is the comprehensive integration of many modern scientific and technological achievements. This mainly depends on the development of many advanced technologies such as electronic technology, automation technology, remote sensing technology and computer technology.
Two sides: ① Advantages: The achievements of a country's space technology can best reflect its scientific and technological level, which is a balance.
An important symbol to measure its scientific and technological strength; It plays an unexpected strategic role in the strength and progress of a country; Economically, it can produce high economic and social benefits; Militarily, it can best show the military strength of a country. As long as a country has space advantages, it will take the initiative in military strategy. Politically, it has a far-reaching impact on improving a country's position in international activities. A major space achievement often becomes the main bargaining chip in international negotiations.
Disadvantages: huge cost; Once an accident occurs, it is basically irreparable; This situation is aggravated by the fact that space technology is used for military purposes.
World security form; Create a lot of space junk.
Patentability: As the result of creative labor, aerospace technology is the crystallization of the wisdom and labor of technology inventors, which contains rich social and economic values.
Third, talk about your views on "osteotomy and breast augmentation" and discuss the problem of "how to choose technology rationally".
A: My opinion on osteotomy lengthening: The notice of the Ministry of Health on strict management of limb lengthening stipulates that limb lengthening is a clinical orthopedic treatment technique, and its indications are bone defects or limb length inequality caused by congenital malformation, trauma, tumor, infection and other reasons, as well as limb deformity caused by diseases. However, normal people use it for beauty, which is an irrational technical choice.
Second, how to rationally choose technology:
(1), define your purpose, what kind of technology to adopt, and form a preliminary plan;
(2) Choose professional technology certified by international, national or professional departments;
③ Choose the most perfect, safe and reliable technology type;
④ The success rate of clinical trials should be carefully investigated to form a clear choice direction;
Considering the two sides of this technology, we should weigh the advantages and disadvantages and make a correct and rational judgment.
