查询词典 wave mode

This paper analyzes the optical characteristics of fiber grating according to the theory of mode-coupling in nonsymmetrical optical wave-guide, which affords the gist for the testing of optical characteristics and tuning characteristics of fiber grating. Moreover, we deduce the linear relationship between reflected wavelength shift of fiber grating and vertical displacement of cantilever beam which the fiber grating is sticked on.

It is found thatthere exist three modes in a magnetized, homogeneous, and collisional dusty plasma:the wholly damped mode due to the thermal diffusion, damped electrostatic dustacoustic wave, and damped electrostatic dust cyclotron wavediscovered by the dissertation for the first time; As neutral gas pressure increases,the damping rates of the EDA and EDC waves increase; The effects of dust densityon the EDA and EDC waves are remarkably different from unmagnetized orcollisionless plasma; A possible explanation to plasma crystallization is suggestedon the basis of the present results.

EDA的阻尼速度随中性气体压强的增大而增大，这一点与实验相符，对于EDC也存在同样的关系。尘粒密度对EDA波和EDC波的影响明显不同于非磁化或者无碰撞尘埃等离子体中的情况。当忽略碰撞时，阻尼的EDA和EDC波回到纯振荡波。最后就尘埃等离子体晶化给出了一个可能的解释。

The function of 3dB fiber loop mirror in fine wavelength partition is studied. With this theory, a novel narrow linear band, dual-wavelength switchable Er-doped fiber laser is realized.2. An unpumped Er-doped fiber and broadband fiber Bragg grating with high reflectivity is served as an auto-tracking filter, where the space hole-burning effect appears when the laser signal travels and forms standing wave, thus the generation of multi-longitudinal-mode is suppressed. Then the high birefringence fiber loop mirror is introduced to act as comb-liked wavelength filter.

The company devotes to develop energy-saving, material-saving, high performance and new type radiator products. It is specialized in the production of Auto air conditioner evaporator, condensers, heater, CPU heat sink, LED the radiator and so on. The company successfully obtains the National Patent Award (the Chinese patent mode 200720056708.4 item). The main focus of the patent is on the whole unity of radiator. Through sophisticated state-of-art production technique and design, the fins are dissembled into different angles and shapes, including trapezoid, triangle, rectangle and even wave shape. It can thus greatly increase the heat dissipation effect by multiplying the surface area.
