probe test method

Probe method could be extended and applied widely because it has the merits of simple operation and low test cost.

探针测流法还具有操作简便、试验成本低的优点，可以推广应用。

Now a laser triangle measuring device instead of test probe is installed on the three-coordinate measuring machine, but this method is still limited by the three-coordinate measuring machine itself.

改进的方法是将激光三角测量头装在三坐标机上以代替触针，从而实现了非接触测量，但此法仍然受到三坐标机本身的限制。

The system uses ultrasonic wave as signal source, with the multi-probe multi-directions sweep, and fluid soak method test the gear.

系统以超声波作为检测信号源，采用多探头多方位扫描、液浸法的方式对齿轮进行检测。
