Outline of China Physics Olympic Competition
Description:

Compared with version 20 13, version 16 has added some contents, such as coriolis force, centroid reference system, virtual work principle, continuity equation, Bernoulli equation, entropy and entropy increase. On the other hand, it is also slightly deleted, such as the scalar product and vector product of vectors, the synthetic center of gravity of parallel forces, and the type of object balance. Some expressions are more rigorous, such as changing recoil motion and rocket into recoil motion ※ Motion of variable mass system ※ Angular momentum theorem of particles and particle groups (without introducing inertia moment) into angular momentum theorem and rotation theorem of particles and particle groups, and deleting the restriction of not introducing inertia moment, loudness and tone of sound, and the increase of * * musical sound and tone noise (the first three items do not need quantitative calculation).

2. The order of knowledge points has been adjusted. For example, the translation and rotation of a rigid body around a fixed axis (version 20 13) is at the end of kinematics, and version 20 16 is an independent new unit, as is the version long ago.

3. In the Executive Summary executed on 20 13, all contents marked with ※ are limited to the rematch and finals. 20 16 began to be further refined, of which ☆ is only the final content, ※ is the semi-final and final content. If there is no regulation, it is generally required to examine the quantitative analysis ability.

Executive Summary of China Physics Olympic Competition

(revised in April of 20 15 and implemented in 20 16)

Note: According to the suggestion of the 9th plenary session of the Chinese Physics Olympiad Professional Committee of the Chinese Physics Society (1990), the Standing Committee of the Chinese Physics Olympiad Professional Committee of the Chinese Physics Society, in accordance with the provisions of the Constitution of the Chinese Physics Olympiad on the proposition principle, combined with the actual situation of middle school students in China, formulated the Executive Summary of the Chinese Physics Olympiad as the proposition basis for the preliminaries, rematches and finals of future physics competitions. Including theoretical basis, experiments and so on. 199 1 was discussed and approved at the enlarged meeting of the Standing Committee of China Physical Olympic Committee on February 20th, and the trial was started. 1991September 1 1 was adopted by the Chinese Physical Olympic Committee at its 10 plenary meeting and is now being implemented.

With the consent in principle of the19th plenary session of the Chinese Physical Olympic Committee in 2000, the Executive Summary of the Chinese Physical Olympic Competition was appropriately adjusted and supplemented. Considering the spirit of properly controlling the difficulty of the initial test questions, the newly added content in the executive summary is marked with "※" as the supplementary content of the retest and final test questions, and the original executive summary is still used for the initial test questions, without adding the revised supplementary content.

In 2005, the Standing Council of the Chinese Physical Society revised the constitution of the Chinese Physical Olympics. According to the revised articles of association, it is decided that the Standing Committee of China Physics Olympic Games Committee will organize the compilation of "China Physics Olympic Games Experimental Instruction" as the proposition scope of the semi-final experimental examination.

20 1 1 Revision of the Executive Outline of China Physical Olympic Games. The revised draft was adopted by the 30th plenary meeting of China Physical Olympic Committee and decided to be implemented from 20 13. In the revised Executive Summary, all contents marked with ※ are limited to the semi-finals and finals.
