mean current meaning in Chinese

平均电流
平均流
平均束流

Monthly change of positive mean current is similar to that of percentage of positive cg lightning , whereas the monthly change of negative lightning is relatively small
正地闪的月平均电流强度变化基本与正地闪所占比例的月变化相似，而负地闪强度变化相对较小。
The diurnal change of cg lightning is obvious , and it generally takes on bi - peak and bi - valley pattern . the two peak values occur at 15 : 00 and 03 : 00 respectively , whereas the two valley values occur at 09 : 00 and 22 : 00respectively . the mean current of positive cg lightning is slightly bigger than that of negative one
闪电的发生也有明显的日变化，总体呈双峰双谷形式， 15时和03时为两个峰值，两个谷值分别出现在9时和22时。
The obtained results indicate that the concentrations of reactants in the catalyst layers in front of t he current collectors are very low , that reduce the utility of catalyst ; the current density at the edges of the channels is many times greater than the mean current density
计算了电池内反应物浓度的分布、电流密度分布、甲醇窜流以及电压-电流特性曲线等。结果表明：集流板前的催化层内反应物浓度非常低；流道边缘附近电流密度比平均电流密度大许多倍。
