The switch rate of thyratron is related to the triggeringsignal. The fast thyristor is usually used in the trigger circuit, but the triggeringsignal is not ideal.
氢闸流管的导通速度与触发信号有关，常用触发电路中使用快速晶闸管，触发信号并不是很理想。

The SIGNAL statement rolls back the changes that were attempted by the triggering statement (that is, our update statement).
SIGNAL 语句回滚由触发语句（也就是我们的 update 语句）尝试的更改。

Infrared radiation heats up the pit membrane tissue, and TRPA1 channels open when a threshold temperature is reached, allowing ions to flow into the nerve cells and triggering an electrical signal.
