后来改了几次，效果都不太理想。不是速度跟不上刷新，就是出现一些莫名奇妙的波。15号的时候决定推倒重做，放弃以前用画板作图的习惯，改用DirectX绘制波形。感觉还可以。

目前只是单声线跟踪，所以有点假~~

下面进入正文-Had done an internal version number for the Beta release version 1.0.0.0 of the simulation software, was just published in the China Forum on non-destructive testing. People feel bad, not only the long code (on the 600KB), and the feature does not and the software. Was changed several times, the effects were not ideal. Refresh is not keeping pace, that is, some baffling wave. 15 over from scratch when the decision to give up the habit before drawing with drawing board, use DirectX to draw the waveform. Feeling also. Currently only a single sound track, so a little bit into the body of the following false ~ ~ ... ...
