通过定义计算，寻找某特定曲线上的拐点，本处以电压电流伏安曲线为例，可修改定义来计算其他曲线-By defining the terms, looking for a particular curve inflection point, the imposed voltage and current volt-ampere curve, for example, can modify the definition to calculate the other curves

用VB.NET写的一个数据采集系统！可以采集温度，电压，电流！并把数据保存到SQL数据库中！还可生成曲线图与导出数据！(data acquisition system collection; collect; gather temperature voltage; electric tension; electric voltage; pressure; tension current; electricity; galvanic current; electric current; e
