等价量的概念及其性质

The Concept and the Qualities of Equivalence

对等价无穷小进行了推广；首先给出等价量的定义，继而推导和讨论了：等价量间的等价特征，等价量和极限的关系，等价量经过四则运算、求导、求积，以及进行复合过程后，在一定条件下仍保持等价的性质。

In the thesis the equivalent in fintinitesimal is spread. The definition of equivalence is given at first, then the author infers the equivalent characteristics among the equivalence, the relation between the equivalence and the Limit. In the end,the process that through arithmetic operations, differential and integral operatioins and composite process the equivalences still remain their charateristics in some condition is discussed.
