A novel switch-transmission theory for the resonant tunneling circuits is proposed which is based on the conventional digital switch-signal theory,and the switch-transmission arithmetic system is also built.

The transmission theorem of cascade AWGs for dispersion compensation system based on time-space conversion is analyzed,and compared with the system of lightwave signal process of cascade grating-double lenses.

Electrostatic discharge current analyzed by transmission line theory;

The arithmetic of Hooke-Jeeves is used to compile the optimization program using the transmission line theory.

Aiming at electromagnetic interference of cable in interconnected system,this paper simulated and computed the crosstalk of coaxial cable,based on the transmission line theory.

For the electric or magnetic currents on the patchs or apertures of the multi-layered FSS,the coupled matrix among them can be gained through the generalized transmission-line theory when the self impedance or conductance matrix are gotten in the method of lines,and the equations for the whole structures is established.

In this article, the author studies the criteria of traditional translation and also deals with the translation practices of practical English with an attempt to show that traditional translation theory has instructive effect on the translation of practical English.

The development of Chinese traditional translation theory corresponds with Chinese translation history.
