Based on the rigorous analysis of the kinetic process of both primary and secondary electrons, the related surface charges were analyzed, and the energy gain of emitted electrons was proportional to the square of the ratio between the tangential and normal component of electric field. In this process, the image force of mirror charges would result in an energy loss. Meanwhile, the effect of field alternation of power frequency ac voltage on electron movement could be ignored.

在前人工作的基础上，进一步严格推导了场致一次发射电子和二次电子的运动方程，分析了电子发射引起的绝缘材料表面带电，表明电子发射后的能量增益正比于场强的切向与法向分量比值 F /// F ^的二次方；同时考虑了在电子发射和运动过程中电荷镜像力的作用，并探讨了交流电压下表面带电的情形，认为当考虑电荷镜像力的作用时，电子的能量增益可能变小，而工频交流电压下电场交变对电子运动的影响可以忽略。

The calculation results show that the normal component of magnetic intensity is symmetrically distributed around the point of the acting force, where the normal component reach the maximum value; while the tangential component is antisymmetrically distributed around the point of the acting force, where the tangential component inverses its direction sharply.

结果表明，空气中扰动磁场的法向强度和切向强度分布特征明显不同，法向强度关于力作用点对称分布，并且在力作用点处达到最大，而切向强度关于力作用点反对称分布，并且在力作用点处有突变；地磁环境下，磁场对位移的影响可以忽略不计；扰动场强与外力成正比。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
