1. With the paraxial expansion equation of the axial charge density, the space charge effect is take count into the transfer function by involving the charge density in the spherical aberration. 利用轴上电荷密度在旁轴区的展开式，得到了考虑空间电荷密度的球差公式和电子图像衬度传递函数；
2. A charge-transfer device that stores charge in discrete regions in a semi conductor and transfers this charge as a packet through a series of switching devices that interconnect these regions. 一种电荷传送器件，它在一个半导体的分立区域中存储电荷，并通过一系列与这些区域互连的开关器件，作为一个信息包传送这个电荷。
3. An object can have positive charge, negative charge, or no charge at all. 一个物体可能带正电荷、负电荷、或完全不带电荷。
4. The content includes the implication and nature of utility charge, theories of charge, the content of utility charge management, as well the system theory of public regulation policy. 主要内容包括：事业性收费的内涵与性质、收费理论；事业收费管理的内容，公共规制政策的制度原理与方法。
