摘　　要：针对被检交流稳压电源输出频率稳定度测试,即测试输出频率随时间的变化情况,本文充分开发和利用LabVIEW8.5开发环境中已用时间函数,采用倒计时显示剩余时间的方法,设计了实现任意设置时间间隔内,对同一被测对象进行多次测量、数据处理、存盘的程序。该程序简单实用,提高了检定系统的自动化程度,对使用者带来极大的方便,具有较高的应用、借鉴价值。When testing the stability of output frequency of the AC stabilization voltage source （viz. the test of the change of the output frequency along with time）, we can make full use of the time function of the LabView 8. 5. By the means of counting down the remain time, this paper design a program to achieve data processing, data storage and repetitious measurement. The program is very simple and practical, it not only improve the automatization of verification system greatly, but also provide important reference and extremely convenience for programmers and users.
