Question 5: The synonym of great scientist Qian Xuesen (19 1 1-) is a famous physicist in China and a world-famous rocket expert. Hangzhou, Zhejiang, was born in Shanghai. 1934 graduated from department of mechanical engineering, Jiaotong University, 1934 studied at MIT and Caltech. After receiving his doctorate from 65438 to 0938, he stayed in school to teach and engage in rocket research. 1947- 1955, he was a professor at MIT and Caltech. 1935 went to the United States to study aviation engineering and aerodynamics, and 1938 received his doctorate from California Institute of Technology. Later, he stayed in the United States and served as lecturer, associate professor, professor, director of supersonic laboratory and director of Guggenheim Jet Propulsion Research Center. 1950, began to strive to return to the motherland, persecuted by the United States, and lost his freedom. 1955 took five years to return to the motherland. 1955 broke through various obstacles and served as the technical director of rocket, missile and spacecraft development for a long time from 1958. /kloc-0 joined China in 1959. He used to be the director of the Institute of Mechanics of Chinese Academy of Sciences, the deputy director of the Seventh Ministry of Machinery Industry and the deputy director of the Commission of Science, Technology and Industry for National Defense. He is currently the honorary chairman of China Association for Science and Technology. Qian Xuesen put forward an extremely important implementation plan for the development of rocket and missile technology in China. From April, 65438 to April, 0956, he served as a technical leader in the development of rockets, missiles and spacecraft for a long time, and made great contributions to the cause and development of rockets, missiles and aerospace in China. Qian Xuesen used to be vice chairman of Chinese People's Political Consultative Conference, member of the Department of Mathematics and Physics of China Academy of Sciences, honorary chairman of China Aerospace Society and chairman of China Association for Science and Technology. Scientific Achievements Qian Xuesen served as the technical director of China's rocket and space program for a long time, and made great pioneering contributions in space technology, system science and system engineering. Qian Xuesen published 7 monographs and more than 300 papers. The main contributions are as follows: ① Applied Mechanics Qian Xuesen has done pioneering work in aerodynamics and solid mechanics of applied mechanics. With feng? Carmen's cooperative research on compressible boundary layer reveals some temperature changes in this field and establishes Carmen-Qian Xuesen method. In cooperation with Guo Yonghuai, the concept of upper and lower critical Mach numbers is introduced into transonic flow for the first time. (2) Jet Propulsion and Aerospace Technology From the 1940s to the early 1960s, Qian Xuesen put forward some important concepts in the field of rockets and aerospace: in the 1940s, he put forward and realized the JATO, which shortened the runway distance; 1949, put forward the concept of rocket passenger plane and the idea of nuclear rocket; 1953 studied the possibility of interplanetary flight theory. In "Introduction to Interstellar Navigation" published by 1962, the concept of a round-trip transportation system between heaven and earth is put forward, in which a large aircraft equipped with a jet engine is the first-stage vehicle and an aircraft equipped with a rocket engine is the second-stage vehicle. (3) Engineering Cybernetics In the process of its formation, the engineering practice of designing stability and guidance systems is the main research object. Qian Xuesen himself is the pioneer of this kind of research work. ④ Physical Mechanics Qian Xuesen's research on combining the physical, chemical and mechanical properties of rare gases in 1946 is a pioneering work. 1953, he formally put forward the concept of physical mechanics, and advocated to determine the macroscopic mechanical properties of matter from microscopic laws, which changed the previous method of measuring mechanical properties only by experiments, greatly saved manpower and material resources, and opened up a new field of high temperature and high pressure. 196 1 year, the Lecture Notes on Physical Mechanics edited by him was officially published. Now the leader of this subject is Professor Gou Qingquan. 1984, Qian Xuesen suggested to Gou Qingquan that physical mechanics should be extended to the engineering and technical field of atomic and molecular design. ⑤ Systems Engineering Qian Xuesen not only refined the practice of China aerospace systems engineering into the theory of aerospace systems engineering, but also put forward the concept of the overall design department of national economic construction in the early 1980s. He also insisted on applying the concept of aerospace system engineering to the whole country and national economic construction, and discussed the social system from the perspective of social form and open complex giant system. The social form of any society has three aspects: economic social form, political social form and ideological social form. Qian Xuesen proposed to divide the social system into three parts: social economic system, social political system and social consciousness system. Corresponding to the three social forms, there should be three kinds of civilization construction, namely, material civilization construction (economic form), political civilization construction (political form) and spiritual civilization construction (ideology). The construction of socialist civilization should be the coordinated development of these three civilizations. From a practical point of view ... >>
Question 6: C++ Reference Question Reference introduces synonyms of objects. The representation of a definition reference is similar to that of a definition pointer, except that it is represented by&; Not *.
For example:
Point pt 1( 10,10); Point & pt2 = pt1; Pt2 is defined as a reference of pt 1. According to this definition, pt 1 and pt2 represent the same object.
Reference does not produce a copy of the object, but only a synonym of the object.
Declaring a reference is not a new definition of a variable, but only means that the reference name is an alias of the target variable name, not a data type, so the reference itself does not occupy storage units, and the system will not allocate storage units to the reference. Therefore, addressing the reference is addressing the target variable.

Question 8: What do temperament and temperament mean in psychology? Hello! Here is my answer:
There is no difference between the two in practical sense.
The following content comes from netizen Ji Gong:
Nature refers to the innate personal nature, not hereditary, but innate.
Temperament refers to a person's nature, which is inherited, including acquired influence, and then forms personal human characteristics. For example, in derogatory expressions, sometimes this meaning is more obvious.
I hope it helps you.
Hope to adopt!
