2. Look up the materials with space technology and analyze how it embodies the nature of technology, such as purpose, innovation, comprehensiveness, duality and patentability.
A: Definitely: Space technology is a technology for exploring, developing and utilizing space, also known as space technology and aerospace technology.
Purpose: The purpose is to study physical, chemical and biological natural phenomena in space by using spacecraft as a means.
innovation: space technology is a fast, wide-ranging science and technology, which can play the most important role on the macro scale.
comprehensiveness: Space technology is a highly comprehensive science and technology, and it is a comprehensive integration of many modern scientific and technological achievements. It 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, and it is 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 a country's military strength. As long as a country has a spatial advantage, it will have 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 a major bargaining chip in international negotiations.
② Disadvantages: huge cost; Once an accident occurs, it is basically irreparable; The military use of space technology has aggravated the form of world security. Create a lot of space junk.
Patentability: Space technology, as the result of creative labor, is the crystallization of the wisdom and labor of technology inventors, which contains rich social and economic values.
Third, talk about your views on "bone-cutting augmentation" and discuss the issue of "how to choose technology rationally".
A: My opinion on osteotomy and augmentation: The Notice of the Ministry of Health on Strict Management of Limb Lengthening stipulates that limb lengthening is an orthopedic clinical treatment technique, and its indications are bone defect or limb unequal length 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 choice of technology.
2. How to choose technology rationally:
1. Make clear your purpose and what kind of technology you need, and form a preliminary solution;
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;
⑤. We should consider the two sides of this technology and weigh the advantages and disadvantages to make a correct and rational judgment.
