The synthesis and design of the conventional filters; Further more, waveguide multiplexer and the general Chebshev filters with transmission zeros were introduced. Multipath coupling Equivalent Circuit are constructed and the relative phase shifts of multiple paths are observed to produce the known responses of the cascaded triplet and quadruplet sections.

给出了传统滤波器的基本理论和设计方法，继而介绍了波导多工器和广义切比雪夫滤波器的综合理论；分析了相位关系和交叉耦合的电路模型；给出了在腔体滤波器中实现交叉耦合的方法。

The curve crossing probability rises gradually with the wavelength, suggesting that the conical intersection be located close to the exit channel. Br is the primary product of the photodissociation of fluorobromobenzene and bromobenzene near 266nm and it is generated through two channels.

由于势能面交叉几率随激光波长的增加有增大的趋势，我们推测势能面的交叉区域应靠近解离通道的出口。o，m，p-C6H4FBr和C6H5Br在266nm激光作用下的光解存在两种解离通道。

We used maize seedlings (Zea mays L.) and tobacco (Nicotiana plumbaginjfolia L.) as material. In the first section, we have investigated cold- shock-induced chilling, drought, heat and salt stress resistance in maize seedlings. In the second section, by modifying the Ca~ and CaM levels, we have tried to establish the involvement of calcium messenger system in the cold-shock-induced cross adaptation. In the third section, we have tried to establish a transgenic tobacco system expression CaMICaMIBP genes, so that the others can use it to investigate the process of physiology and biochemistry which endonuclear and cytosolic calmodulin have taken part in.

以玉米幼苗和烟草为实验材料，本文第一部分通过将玉米幼苗进行短期冷驯化后对冷胁迫、干旱胁迫、热胁迫及盐胁迫的影响，试图证明玉米幼苗中交叉适应现象的存在及其机理；第二部分通过外源修改Ca~(2+)和CaM水平，研究了钙信使系统在交叉适应现象中的可能作用；第三部分通过建立诱导性表达CaM/CaMBP转基因烟草体系，便于研究受细胞质CaM和细胞核CaM调控的各种生理生化过程。

In this paper, the necessity of the foundation of a new crossed discipline——Tectonogeo-physics which was proposed by author more recently, and its theoretic and practical signifi-cance to develop the earth science are expounded from the brief review of the history on thecrossed combination between geotectonics and geophysics .
