摘　　要：首先介绍了OpenGL的功能以及利用OpenGL绘图一般过程和方法,然后介绍了胎心率曲线常见的种类以及合成方法。可以真实地模拟胎儿期的心率以及母亲的宫缩曲线。不仅可以合成波形而且也可以实现图形的翻页、打印、保存等各种功能。分析了在绘图时出现的图形闪烁问题,提出利用双缓存解决绘图过程中的图形闪烁问题。OpenGL function and the common drawing techniques approaches of applying OpenGL are introduced.The common types of fetal heart rate（FHR）curves and the synthesis of the heart analog waveforms of the fetus are described. The fetal ECG waveform curve and the mother＇s UA curve can be simulated by OpenGL very well.Not only the waveforms can be synthesized,but also the functions such as page turning,printing and picture saving can be implemented with it.The problem of the pattern flicker appearing during drawing was solved with the double-buffering after analysis of the pattern flickering problem.
