Through analyzing the research result of four series studies, we conclude that the description about toplogical perception that is prior to the perception of local featural properties does not fit to the visual perception, and the figure visual perception is not affected by the different geometrical levels, and the relative perceptual salience of different geometrical properities is not consistent with the hierarchy of geometries according to Kleins Erlangen Program.

四个系列研究的研究结果表明，陈霖的拓扑性质知觉理论对视觉系统具有早期抽取图形拓扑性质的描述欠妥当，图形视知觉的加工过程并不受图形几何变换功能层次的制约，不同几何性质的相对知觉显著性与克莱茵的埃尔朗根纲领所描述的几何层次不一致。

Based on English definition of the six properties which a relation R defined on a set A and utilizing the logical characteristic of implications, two aspects of ordered-pair and the matrix MR are considered, and the properties of the R is analyzed one by one. A few useful conclusions are summarized as determining the properey of the R. The following collections are also analyzed between reflexive and irreflexive, symmetric and antisymmetric, symmetric and asymmetric and among irreflexive, antisymmetric and asymmetric.

根据定义在一个集合A上的关系R的六个性质的英文定义，利用蕴含式的逻辑特点，从有序对和关系R的矩阵M两个角度对每个性质逐一进行分析，得出在判定关系R的性质时可用的结论，并且分析了自反性与非自反性之间、对称性与反对称性之间、对称性与非对称性之间、非自反性和反对称性以及非对称性之间的联系。

The correlation between liquid fragility of alloys and micro/maro -properties in liquids or their corresponding solids, as well as the correlation between liquid fragility and potential energy landscape, is of great significance for understanding the nature of liquid fragility and the relationship between thermodynamics and dynamics,.

研究金属液体的脆性性质与液体中微观或固体中宏观性质的联系以及研究其液体的脆性与能量图谱的联系，对于揭示液体脆性的本质、热力学与动力学性质相关性问题以及能量图谱的量化工作具有深远的意义。

The influence of solvent effect on optical performances of photochromic material ethyl red has been studied.

研究了溶剂性质对光致变色材料乙基红光学性质的影响。

Acetate groups charge ZnO nanocrystals negatively and passivate the surfaces,reducing the surface defects and visible emission centers. Resultantly, the increase of acetategroups lead to the quench of visible emission and improvement of photoluminescenceproperties. At appropriate concentrations, the hydroxide groups mainly passivate the surfaceand improve the photoluminescence properties.

研究发现，氢氧化锂/醋酸锌的比值对胶体氧化锌量子点的发光性质有重要影响；醋酸根基团通过使氧化锌粒子带负电荷并钝化其表面，使得氧化锌纳米点的表面缺陷和可见发射中心大大减少，因此醋酸根浓度的增大导致了可见发光的淬灭和发光性质的增强；氢氧根基团在中等浓度时主要起钝化氧化锌表面的作用，使产物的发光性质得到改善。

The content and size of the plastic grains in the reservoir clasts are important factors controlling the reservoir property. Diageneses are a crucial factor of reservoir property, in which consolidation heavily affected reservoir property, cementation was only an important controlling factor influencing reservoir property in the partial area and the influence of dissolution was weak.

储层碎屑组分中的塑性颗粒含量和粒径是储层性质的重要控制因素；成岩作用是储层性质的决定性因素，其中压实作用对储层性质的影响最大，胶结作用仅在局部地区成为重要的控制因素，溶蚀作用的影响是比较有限的。
