coef

基本解释

Average surface heat transfer coef.
平均换热系数
Desplay => Contours => Wall fluxes => Surface heat transfer coef.
选择有关的流-固表面即可显示和输出传热系数。
In a LC oscillator add some C with -ve temp coef to cancel the +ve temp coef of the L for min drift with temp.
在LC振荡器中增加一些负温度系数的电容C来抵消正温度系数的电感L;得到最小的温漂.
Power MOSFETS on-resistance will have a -ve temp coef and not +ve at low current levels. This is important to remember when paralleling devices.
功率MOSFETS导通电阻有负温度系数，小电流时有正系数。当并联这些器件的时候记住以上很重要。
The results show that aluminium alloy foam has a high filter efficiency, low filter resistance, large infiltration coef...
证明所研制的泡沫铝具有过滤效率高、过滤阻力小及渗透系数大的特点，其透流性能优良。
