谈力学中的“三大定理”与过程量、状态量的关系

Chat in the mechanics "Three great theorems "Measure against the process 、Condition amount relationship

力学中所研究的许多问题,都直接涉及到某一物理现象发生的整个过程,或者是过程中的某些状态。因此,相应地就引入了许多关于描述某些物理过程的过程量和用来描述某些特定的物理状态的状态量,从而来定量地分析、研究某些过程中这些物理量之间的变化关系及引起变化的原因。

Much problems which researcied in the mechanics , Wholly directly relate to the entire process that some physics appearance happen , Or is some conditions in the process o Hence , Relevant the earth was draw muchly measuring and is used for depicing some specially designate -d physics conditions amount on the process to depict some physics processs , Thereby analyse with coining .the ration , The alternation relationship which researcied in some processs between these physicals quantity reaches to arouse the alternation reason .
