Then second class are the macroscopic models describing directly macroscopic quantities such as charge density , charge current density , energy density and temperature etc . 另一類是宏觀模型,其直接描述電荷密度,電流密度,能量密度和溫度等一些宏觀量。

The aim of this study is to explore the concentrating effects of both the electric current density and the stresses in the plate due to the existence of the elliptic hole 其研究重心是定量計算橢圓孔對電流密度以及板內應力分布在橢圓長軸端點處的集中效應。

Current density doubles when the area of effective contact between tissue and electrode is halved , provided that hf current remains contant 如果高頻電流強度保持不變,那么人體組織和電極之間的有效接觸面積減半將會使電流密度增大一倍,這將產生四倍的熱量。

The distributions of current density and potential on the negative plates with the radiational or expanded grid designs are more uniform than those on the positive plate 輻射式和拉網式負極板在化成開始時電流密度和電位的分布都比正極板上分布均勻得多。

This results in a fourfold increase of heat ( correspondingly , heat drops by 75 % if current density is reduced by half , e . g . by doubling the effective electrode contact area 相應地,如果將有效的電極接觸面積加大一倍,電流密度將減少一半,熱量則減少75 % 。

From the practical results , the protection potentials and protection current densities meet the design requirements and are in accord with technical standards 從實際運行的結果看,罐底板的保護電位都達到了設計要求和標準規定,保護電位分布相當均勻。

Although battery ' s working voltage plateau decreases with increasing of discharging current density , the exporting capacity of the battery has little changes 雖然放電電流密度的提高使電池的工作電壓平臺降低,但是電池的可輸出容量變化不大。
