This, in turn, causes the conductivity of the nanotubes to change-how much is a characteristic of each gas.
这样又导致了纳米管的导电性发生变化，而我们可以根据导电性变化的多少来鉴定每一种毒气。
2
The characteristic time of electrostatic equilibrium process in decided by conductivity and permittivity of material.
静电平衡过程的特征时间由物质的电导率和电容率决定。
3
The conductivity of a solution is sensitive to the presence of impurities, so its value is meant to be more an index of impurity than a characteristic constant.
