In the paper,the working principle, key technology, typical characteristics parameters of the module are given. The module has stabilized the center wavelength of laser diode by controling its temperature. It has supplied the light source with the characteristic of stable center wavelength for wavelength devision multiplexing system application.
At lower temperature where martensite isstable, there are three fixed points: one representing stable center and the other two describingunstable saddle points.
But the way used to find out the former stable center is different among different statistical schools and that leads to obtain different stable centers.

This paper establishes some basic concepts of the random region and random region function. From these concepts and with the existence of a random stable point of a random region function of the random region, the necessary and sufficient conditions of the existence of a random stable centre of any random region are defined.
The flow process is the most stable and the microstructures at the center and the edge of specimens are markedly refined by DRX at the temperature of 593K and the strain rate of(1.0s~(-1)).
the extension of a region, and the kernel-preserving extension of a region are established by the author. Starting from these concepts, the new definitions of a region function is given.
The module has stabled the center frequency of laser diode(LD) by controlling it's temperature. It has supplied the light source with the characteristic of stabling center frequency for wavelength devision multiplexing system application.
In this paper, by numerical methods, a DMD micromirror system is discussed. Some nonlinear phenomena are observed, i.e., the stable property of equilibrium points are studied in the phase space, and the larger the voltage amplitude applied to the micromirror, the further is the equilibrium position .
From these concepts, and the existence of a random stable point of a random region function of the random region the necessary and suficient conditions for the existence of a random stable centre of any random region are defined.
In this paper, a family of travelling wave solutions of nonlinear internal gravity wave in stratified shear fluid is analyzed. An autonomus dynamic system of firstorder differential equations with perturbation velocity u and desity p as unknowns is thus obtained. Qualitative analysis of the topological structu re of integral curves of this system in the neig-hourhood of the origin on the phase plane with u. ρ as cartesian coodinate axes is given.In the plane with parameters du/dz (the shear velocity)and N2 ...
The purpose of this paper is to extend points function and interval functions theoretics to an arbitrary region. For this, the new theory, the contraction of a region, and the retraction of a region; the extension of a region, and the kernel-preserving extension of a region are established by the author. Starting from these concepts, the new definitions of a region function is given. And a kernel (i. e. fixed point) of a region function is connected with a stable centre of defining region of such a region f...
