The field and potential inside each region are calculated by only taking into account the discrete charges that surround it 每一區(qū)域內(nèi)的電場和電位僅由離散在該區(qū)域周圍的模擬電荷求解。
In international , electric potential is used widely . it is expensive to experiment with the method 高溫環(huán)境下疲勞裂紋長度的測量一直是個難題,國際上常用的測量方法是試驗成本較高和電位法。
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(wǎng)式負(fù)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。
And it is well known that the non - uniform current and potential distributions on the plate can obviously affect the active mass utilization , especially for the positive plate 而且極板上不均勻的電流和電位分布會明顯影響活性物質(zhì)的利用率,尤其是正極板。
At the end of the formation , both current and potential distributions are uniform . however , their distributions on the negative plate with the expanded grid design are a little more uniform 化成結(jié)束時電流密度和電位分布都比較均勻,且拉網(wǎng)式負(fù)極板比輻射式負(fù)極板更均勻。
And its usage on cmcpe was further less . three organic reagents were used as modifier in the fabrication of cmcpe bonded with solid paraffin in our research 本文首先以固體石蠟為粘合劑,以三種常見有機(jī)試劑及其特定的形式作修飾劑制備了cmcpe ,并分別用作電流型和電位型電化學(xué)傳感器測定金屬離子。
When formed for 8h , because most of paste on the negative plate has converted into lead , the polarization increases and the potential changes greatly , these distributions on the two kinds of negative plates become non - uniform again 當(dāng)化成8h時,由于負(fù)極板上的鉛膏大部分轉(zhuǎn)化為鉛,極化上升,電位變化很大,所以兩種負(fù)極板上電流密度和電位分布又變得不均勻。
When it is discharged at high - rate , the distributions are also the most uniform at the end of the discharge . this indicates that the positive plate with the red lead has the better discharge performance than the other two kinds of positive plates 含紅丹的正極板在化成初期電流密度和電位的分布最均勻,極化最小,在高倍率放電結(jié)束時,其電流密度和電位分布也最均勻,表明含紅丹的正極板的放電性能比其它兩種正極板好。
For special example , the closed form solutions for complex potentials in matrix and inhmogeneity regions are derived explicitly when interface containing single crack or rigid line , and the appropriate expressions of the electro - elastic field intensity factors at the tip of crack or rigid line are examined 作為特例,求出了界面含一條裂紋或剛性線夾雜時基體和夾雜區(qū)域復(fù)勢的封閉形式解;同時計算了界面裂紋和剛性線尖端應(yīng)力和電位移場強(qiáng)度因子。
