为解决工程试验中求滞回环面积速度慢的问题,介绍了利用常用办公软件Excel和Origin快速求得滞回环面积的两种方法和计算前对原始数据进行保形映射处理的方法;并通过实例分析,证明了保形映射处理的重要性。通过与传统画网格方法比较,说明利用此两种方法求滞回环面积具有快度快、计算结果准确的优点。

In order to solve the problem that calculating loop area was slow among actual test,two rapid calculation methods of loop area by using usual office software of Excel and Origin were introduced. The method of disposing original data using conformal mapping before calculating was also introduced,and proved it was important to conformal map before calculating by analyzing the actual example. Compared with the traditional method,above two methods were more convenient and accuracy.
