两极

This paper,by applying the theory of probability statistics,explains the relationship between the emission current I and the interelectrode voltage U in the thermoelectron emission phenomene,and then gives the expression of their relationship:I=ImΦ.

本文应用概率统计的理论对热电子发射现象中发射电流 I和两极间电压 U之间的关系进行了解释，得出它们的关系是： I=ImΦ，并给出关于参数 Im、 a、 b的确定方法。

The intergrowth,which means the more freedom human beings have,the more freedom they lose.

Due to the chaos of "null distance" in Donne\'s cognition, a dynamic movement has been produced between the two poles on a horizontal axis in his texts, which led to the occurrence of subjective and textual "intermediacies". And this is the characteristic of Donne\'s intermediateness.

由于多恩认知中"零距离"的混沌，导致了其主体的"间性"和文本的"间性"的出现，令多恩文本在横向组合轴上产生事物两极间的动态运动，从而产生多恩中间性的(来源：A47BCdc论文网www.abclunwen.com)特征。

The results show that, the distribution of magnetic field and electromagnetic force in the aluminum film on the cathode slope are in symmetry to the long axis of the cell, especially the magnetic force is in the same direction as the gravity force, which is in favor of the aluminum discharging from the cathode slope. The highest fluctuation of aluminum pad surface in the accumulation sump is 0.021 m, which still remains within the safe range, and will not cause interpolar short circuit, so a normal operation process could be maintained with the same bus bar configuration as the current 75 kA aluminum reduction cells.

结果表明：阴极斜坡表面电磁场和电磁力场分布基本呈沿电解槽长轴对称分布，且电磁力与重力方向相同，这有利于阴极表面电磁力向聚铝沟排放，而在电磁力作用下，聚铝沟内铝液波动最大幅度为0.021 m，仍保持在安全范围之内，不会引起两极短路现象的发生，表明在现有75 kA普通预焙槽母线配置方案下，可以维持导流型结构电解槽的正常运行。

The results are as follows:① The mean spatial position of the tropical tropopause and the polar tropopause approximately consistent with heating fields of the tropopause, and isopiestic, isotherm present zonality and appear wave motion at the middle and high latitude . The tropopause temperature and pressure are not symmetrical between two hemispheres.② The interannual variations of the tropopause zonal-mean pressure and temperature anomalies are remarkable.

结果表明：①热带对流层顶和极地对流层顶的平均气压场的空间位置和热状况大致吻合，并存在空间波动性，两半球对流层顶的温压场具有显著的非对称性；②对流层顶的纬向气压与温度距平场都具有不同尺度的年际和年代际变化，两极地区对流层顶的温压场最不稳定，两半球中纬度地区的时间演变尺度存在明显差异。
