In the space filled with dielectric, Coulomb's law should be: F = kQ1Q2r2.V in the electric field generated dielectric polarization bound charge and bound charge generated within the medium electric field, and external electric field in the opposite direction, so to diminish the external electric field.

在充满电介质的空间里，库仑定律应为：F＝kQ1Q2r2.V在电场作用下电介质极化产生束缚电荷，束缚电荷在介质内部产生电场，与外电场方向相反，所以使外电场减弱。

In the area of sharp depth change, the pattern of average current field varies sensitively with wind speed change, while in the area of flat and gentle bottom, insensitively. The current direction in shallow water was consistent with the direction of the wind, while against the wind direction in deeper water and responded slowly.

在水深水平变化较大的区域，垂直平均流场结构对风速变化的响应较为敏感，易形成环流，浅水区垂向平均流向和风向一致，深水区则和风向相反；水深变化较小的水域，流场结构对风速变化的响应则较为迟钝。

Based on the aberration theory of AWG, a new-type flat-field AWG is designed. The focal signals of all wavelengths of operation are focusing along a straight line perpendicular to the propagation direction. Three stigmatic points restrain three dominant geometry parameters. Furthermore, a new-type flat-field wavelength router with both flat input field and flat focal field is also designed.

基于阵列波导光栅的像差理论，利用三个无像差点约束三个主要结构参量，设计了新型平场聚焦阵列波导光栅，使得所有工作波长的输出信号都聚焦在与光束传输方向垂直的直线上，并进一步将其拓展为同时具有平输入场和平聚焦场的新型平场波长路由器。

According to the lowest free energy law of forming steady configuration, it is proved that under the hypotheses of the model the necessary and sufficient condition for the stabilization of magnetic structure is the moment direction of the total saturation magnetization 〓 of a compound should be parallel to that of external magnetic field 〓, and the direction of each sublattice moment 〓 must also be parallel to that of the effective field B〓 acting on the 〓.

根据形成稳定结构的能量最低原理，证明了在该模型的假设条件下，系统磁结构稳定的充要条件是：化合物总的磁化强度m与外磁场B的方向相同，并且各次晶格的磁矩m〓与作用于它们的有效场B〓的方向一致。
