The total conductivity and electron conductivity of the electrolytes were measured by four-electrodes AC impedance and Hebb-Wagner(polari-)zation methods.
利用四电极交流阻抗法和Hebb-Wagner极化法测量了电解质的总电导率和电子电导率。
Four pulps were sieved to long, middle and short fiber, and total charges and surface charges of the each fiber constituent were determined.
分析了漂白马尾松化学浆、漂白芦苇化学浆、马尾松热磨机械浆和废纸浆的长、中、短纤维含量以及它们的总电荷量和表面电荷量。
According to the charge distribution character ensuring the steady electirc current, it is pointed that the electric field intensity E in differential form of the Ohm s law is the component of the total electric field in the direction of electric current, and the deviation between the component and total electric field direction is quite small and their quantities are nearly equal.
以稳恒载流圆直导线为例 ,根据保证稳恒电流的电荷分布特点 ,指出欧姆定律微分形式中的电场强度 E应是总电场在电流方向的分量 ,同时又指出一般情况下这一分量与总电场方向偏差很小 ,量值基本相
