| 摘 要： | 对误差概念，给出了一套建议性的基本符号，定义了伴随相对误差，并对相对误差与伴随相对误差的量化关系进行了讨论，得到两个相关定理，从而为解决实际问题提供了一定的理论基础，就处理实际问题时的客观量的划分，给出了两个准则，并具体分析了几个典型实例，最后用基本符号表述了有关误差传播的若干基本结果。

| Abstract: | A set of basic symbols are assigned about error concepts.The adjoint relativeerror is defined and the quantitative relation between relative error and adjoint relativeerror is discussed.Two theorems can be obtained from the definition and discussion.This offers beneficial theoretical base for practice application.Two criterion are given forthe division of objective quanties when practical problems are dealt with and several examples are analyzed.At the end of the essay,some basic results about the error propagation are indicated with basic symbols. |

| Keywords: | relative error adjoint relative error mathematical quantity objective quantity |
