这里需要提醒那些在化学课上打瞌睡的人，滴定法是计算溶液中物质浓度的一种方法。

Titration, to remind those who dozed through their chemistry lessons, is a way of working out the concentration of a substance in a solution.

That signal is carried here, for example, by the concentration of second messengers - the concentration of something else.

这里这个信号由,第二信使的浓度,即另一种物质的浓度来传递
