摘　　要：常规的时间检测方法,在Windows的CPU时间片轮转多任务分配机制下,无法准确检测程序中算法的执行时间。为精确检测程序中算法的执行时间,通过分析程序运行环境的特点,说明不同时间测试方法的优缺点,并给出代码示例,对应提出了适用于.NET环境的时间测试方法。应用此方法,通过对数值积分算法的时间检测得出多组数据。对比结果表明,此方法较常规方法检测所得的时间更为准确,能为精确分析和评价算法的执行效率提供有效可靠的参考。Regular time detection methods can not accurately detect the program algorithm execution time when under Windows environment that CPU time slice rotates multi-tasking allocation mechanism. In order to detect the algorithm exe- cution time of the program accurately, by analyzing the characteristics of the program operating environment, to illustrate ad- vantages and disadvantages of different time test methods, and gives code examples. The article corresponds to propose a time test method for. NET environment, as an application of this method, by numerical integration algorithm＇s time detection to draw multiple sets of data. Comparing the results, it showed that： compared with the conventional method, this method is more accurate, and it can be able to provide efficient and reliable reference for analyzing and evaluating the efficiency of the algorithm accurately.
