提出一种使用熵编码和非等长枚举码的格点矢量量化算法用于小波图象的编码，该算法以格点标记码码长的变化来适应输入矢量的非均匀分布，解决了传统的乘积码塔形矢量量化和分块均匀格点矢量量化算法中格点的调整难以与输入矢量概率分布实现良好匹配的问题。

And we show the form of the reduced density matrix master equation and its solution at first .Then we derive the solutions of Ohmic spectrum and Laurent series spectra master equations. Finally, we make analysis of the solutions of stochastic process and their coefficients from the cumulants, late time uncertainty function and linear entropy

首先展示了有关约化密度矩阵主方程的形式和解的形式；接着推导出欧姆谱和分洛朗级数谱这两个随机过程主方程的解；最后从累积量，延时不确定关系和线性熵等方面来研究随机过程主方程的解及其系数特点。

The paper discusses the fundamentals of laser generation from the angle of nonequi- librium thermodynamics and also explains that the so- called negative temperature means the decrease of entropy in nonequilibrium , so that system tends to be ordery.

从非平衡态热力学角度讨论了激光产生的基本原理，其中还解释了所谓负温度意味着非平衡态熵减少，系统趋向有序。

The Carnot heat engine is discussed in detail to show how there is an upper limit to the efficiency of heat engines and how the concept of entropy arises from macroscopic considerations.
