摘要
阐述了动量定理和动能定理的适用条件,并通过几种物理模型的讨论,分析两大定理的使用范围,得出在解决连续作用的流体问题时利用动量定理更为方便的结论。
The paper elaborates the conditions for the application of kinetic energy theorem and momentum theorem, analyses the application scope of the two theorems through the discussion of several physical models and finally draws the conclusion that it is more convenient to use kinetic energy theorem in determining the role of continuous functioning fluids.
