Ion channel activity had the character of voltage-dependence. Some cells, which did not exhibit sodium currents exhibited, delayed rectifier potassium currents.
并且离子通道活动具有明显的电压依赖性，在没有记录到钠电流的细胞记录到延迟整流钾电流。

On top of that, there is weak dependence on voltage by these lasers, and they are not sensitive to temperature change.
除此之外，这些激光器对电压依赖程度低，对温度变化也不敏感。

Also, with an adjustable voltage source, the voltagedependence of the resistance under test can be obtained directly.
