According to the information granularity and probability, the evidence theory is generalized to fuzzy sets. The expected certainty and probability are defined as generalized belief function and generalized plausibility function respectively. The proposition is depicted with belief function, plausibility function and genus probability function. The proposition or evidence uncertainty is described in different aspects by the belief degree of estimation, un-rebut and conditional evidence.

摘要：多波形变频电源波形发生器采用单片机设计，用程序产生变频电源波形。程序实现步骤：先计算构成波形的点数及数值，存到指定存储区，再读取数据, 经D/A转换后输出波形。进行D/A转换时，输出一个点的时间间隔须小于D/A转换所需时间。若波形频率有误差，在程序中设置延时程序或加空指令NOP修正。

Abstract: The waveform generator of variable frequency power supply is designed thin SCM, the waveform of frequency power supply is created by using the program. The program procedure: first, the point numbers formed the waveform and their values are calculated, and save them to the appointed memory area. And then read data, perform D/A conversions and output waveform. When then generator outputs data and performs D/A conversions, the time interval of outputting one point must be less than the time of performing D/A conversions each time. If frequency of waveform has error, either setup a delay procedure or add an instruction NOP in then procedure to revise.
