讨论了电子积分器的工作原理及其在设计上的难点和关键技术，设计了一种带有补偿机构的新型高精度低漂移的电子积分器，通过实际应用发现该积分器可实现对瞬变小信号进行高精度的测量。

The working principle of electronic integrator and the difficult and critical technologies in its design was discussed. A new kind of electronic integrator with a compensation mechanism was designed with high precision and low drift. The practical application showed that the integrator can be realized highprecision measurement of small transient signal.
