给出了数据采样频率是物理量变化频率10倍、8倍和6倍以上时测量精度的适用范围。

And it gives the suitable limits of measurement precision respectively, when the sampling frequency of data is 10 times. 8 times and 6 times of the frequency of physical change.

对于超高速数据采样频率来讲，一般的数据传送系统是不能满足要求的，在这里介绍了一种在板存储器方式传送数据方式。

For the exceeding-speed data gathering frequency, the common data transmission system is to can't up to the request, here introduces a kind of on -board RAM transmission method.

但采样频率过高会增加处理的数据量，从而降低泄漏检测的速度。

But the high frequency of sampling will result in the increase in data collecting, thus reduce the velocity of leaking detection.
