The reversal of any entropychanging transformation would be neither reasonable nor possible . 熵的任何反向变化都是不合理的也是不可能的。
In many kilns the air flow can be reversed in order to reduce these differences . 许多干燥窑内的空气是可以反向流动的,为的是减少这种差异。
Above the inversion point the temperature in the bore hole decreases as the depth decreases . 在反向点以上,井孔内的温度将随着深度的变浅而下降。
In the course of time positive and negative acceleration impulses tend to cancel one another . 在长时间中,正向和反向加速度冲击有互相抵消的趋势。
The photo-current was found to closely follow the eletro-absorption at large reverse bias values . 在很大的反向偏压下,光电流紧随着电吸收发生变化。
These numerical equalities would not exist if any ordinary engine cycle were reversed . 如果将任一普通热机的循环方向反向,那么以上这些相等数量是不存在的。
The resultant force on the loop is evidently zero, since the forces on opposite sides are equal and opposite . 这一回线所受的合力显然为零,因为作用在相对两边上的力是等值而反向的。
The differential transformer secondary windings are connected in subtractive series so that the output is zero at balance . 差功变压器的次级线圈接成反向串联,以便在平衡时输出为零。
The presence of a large density of contaminant causes anomalous increases in the diode current with increasing reverse bias . 大量沾污也会使二级管电流随反向偏压的增加而呈现反常的增大。
The displacement current mechanism is operative only for capacitors under reverse bias or very weak forward bias conditions which maintain a space-charge layer . 位移电流的机理只对反向偏压或要维持空间电荷层所需要的非常弱的正向偏压条件下的电容器才有用。
