trigger source

position the trigger source switch(28) toward the stable waveform.

调整触发开关（SOURCE28）来得到稳定的波形。

The trigger signal at the same time is used as the light source driving signal. We number each PMT separately and record the measurement results in the database systems.

触发信号同时作为光源驱动信号，每个PMT进行分别编号，测量结果记入数据库系统。
