This paper to introduce a new experimental method of dispersion phenomena, in this experimental method, it can be directly observed by different substances uneven medium, the dispersion arising from the various phenomena of the material in different light source through uneven medium, the emergence of two different spectral dispersion surface, spectral noodles Bright (Bright-Line Spectrum), and dark lines is how it is formed and a series of important experimental phenomena.

We find that this new phenomenon is very interesting, and looks contrary to the usual Christiansen effect, but can be explained with Lorentz dispersion model accurately together, so we call it reverse-Christiansen effect. Exactly at this frequency, the refractive indices of these tow materials are equal, and absorption coefficients are very small.

我们发现，这个新现象非常有趣，它与克里斯坦森效应表面上相反，但都可用Lorentz色散模型给予精确地解释，於是称它为反克里斯坦森效应，在该效应出现的频率两种材料的折射率相等，且吸收系数都非常小。

It is shown that the complex dispersion relations, for both TE and TM waves, are strongly power dependent and most importantly, the bistability phenomena will no longer exist if the absorptive loss is high enough.

表明TE和TM波的色散关系都与功率密切相关，尤其重要的是，如果吸收损耗足够大，双稳现象就不再存在。

In this paper a systematic analysis is made about the principle and characteristic of the round fiber dispersiveness based on the dispersive principle of the little drips which can produce rainbow .

以产生虹现象小水珠的色散原理为基础，分析了透明圆形截面纤维在平行光照条件下，一次内表面反射光中笛卡尔线的色散机理与特征；证明了透明圆形截面纤维与水珠在产生虹现象时的色散机理与特征是相似的；揭示了透明圆形纤维内部反射光的特征。

Besides, the reduction of the dispersion part of potential leads to a lower critical temperature and higher in-plane part of molecular dipole moment; however, because the reduced critical temperature is relatively small compared with that of a 3D system, disappearance of the critical point has not been observed in the quasi-2D SM system within practical scope of the simulation.

尽管受到插入困难的限制，本文没有直接发现随着色散作用的减小汽液共存消失的现象，但根据对模拟结果的分析及对偶极作用的讨论，本文猜测这种情况在更小的色散作用和更低的温度下仍然是会发生的。

The initial-boundary value problem of dispersive equation is a kind of mathematical model, in this paper, it has been followed the ways of other scholars and used a new method and got a new difference scheme. It was a three layers ten-point implicit difference schemes.

色散方程的初边值问题是在孤立波这样的物理现象中抽象出来的一类数学模型，在前人构造的众多差分格式的基础上，使用新的构造方法，给出了该问题的三层十，点隐式差分格式。

He published prolifically on hybrid sterility, developmental rates, enzyme polymorphisms, genetic responses to environmental change, and behavioral phenomena, such as dispersion rates.

The results showed that under the given experimental conditions,the surface layer with richiron and poor copper was formed in the surface worn region of the semimetallic friction material,the depth of organic ingredient pyrolysis caused by friction heat in worn surfaces was atout 0.35mm; the semimetallic friction material containing 15%-20%of Cu had better wear-resistance,and can form a even and continuous transfer film of copper; crack peeling was the importantmechanism of the counterpart.

半金属摩擦材料具有摩擦系数稳定，耐磨性好，对环境污染小和对偶件表面损伤小等优点，但其在摩擦热和界面应力等因素作用下，表层会发生弹性变形，塑性变形，元素扩散，组分转移和摩擦化学反应等现象，因此，利用扫描电子显微镜X射线能量色散谱和差热－热重分析，对铜纤维增强的半金属摩擦材料与灰铸铁滑动摩擦表面层的特性作了分析研究，考察了表面层特性对摩擦损行为的影响。
