It is found that there exists an obvious prepeak in the low-Q domain (Q=15.7 nm^-^1) of the structure factor. In the X-diffraction pattern, the liquid diffraction curve is corresponding with the solid diffraction curve. There exist the prepeaks for them in the low-Q domain, which shows that there is the comparability in the microstructure between them.

采用紧束缚原子间作用势，利用分子动力学模拟的方法研究了Al5Fe2合金熔体的微观结构，发现在结构因子的小角部分(Q=15.7nm^-^1)出现了一个明显的预峰，并得到X射线衍射实验的进一步印证，在实验测得的合金衍射图样中，液态衍射曲线与固态衍射曲线间存在着很好的对应关系，它们在小角部分都存在峰位，这表明Al5Fe2合金熔体与其固态在结构上存在着很大的相似性。

The rheological character of a polymer often appears as shear-thinning. Most polymers behaviour in a solution can be explained by the polymer chain or hard sphere theory. Other than that, shear-thickening polymer solution also exists. Its behavior can be explained by dilatant theory, which suggests that the shear-thickening of the solution is due to the swelling of the polymer particles. This phenomenon often occurs in suspension or emulsion. Solution exhibits a mixed behavior can also be found whose behavior is such that shear-thinning occurs under low shear force and shear-thickening occurs under high shear force. Under this circumstance, the viscosity versus shear force graph exhibits a spoon shaped curve. The rheological study can be applied to the dispersion of paint which can predict the dispersion effect of various polymer materials in solution.

中文摘要一般高分子聚合物溶液的流变行为多半呈现剪稀(shear-thinning)的现象，而大部分的高分子在溶液中的行为是以分子链或是硬球观点来解释，另外也有剪稠(shear-thickening)现象的高分子溶液，其流变行为则是以膨胀体观点来解释，即在高剪切力下，由於高分子团体积变大而使溶液黏度升高，这在悬伏液、乳液等常见；但也有在低剪切力下，溶液具有剪稀的行为，而在高剪切力下却成现剪稠的行为，在黏度对剪切力作图时，会呈现出一个勾形曲线的图形；流变行为的探讨可应用在涂布材料的分散技术上，以推测不同的高分子溶液对分散效果的影响。

Moreover, we find that there exists a special value of the parameter λ which characterizes the dependence of DM interaction on the dimerization.

另外 ，发现DM相互作用对二聚化位移的依赖程度参量λ存在一个特殊点λc，当λ=λc时，DM相互作用对二聚化没有影响。

Author analyses the cost, benefit and efficiency in detail, and comes to three conclusions: first, the aim is to get the minimal cost from the sum of direct cost and erroneous cost in economy; second, the highest point exists when marginal cost crosses marginal revenue; third, the design of the minimal cost in criminal summary procedure system must insist three principles: punctual, brief and justice.

在这一部分中，笔者通过对刑事简易程序进行成本分析、收益分析以及效率分析得出了三个重要的结论：一是从经济学的角度看，刑事简易程序的目的就是要使直接成本和错误成本之和最小化；二是刑事简易程序成本投入的最佳水平是其边际成本与边际收益相交的均衡点；三是为了实现成本的最小化，在设计刑事简易程序制度时应当坚持三个原则——及时原则、精简原则和最低公正原则。
