Research on self - organization of complex system on element periodic table ;2. The formula can be used in calculating thirty quantitives or more of element and its compounds in the same tribe of the element periodic table .

将同系因子1／N用于元素周期表，以N为周期序数，P作为各元素或其化合物的性能，利用公式P＝a＋b／N对周期表中各元素及化合物30多种性能进行拟合，得到了良好的结果。

All these lead to a suggestion of a two step method technical route in which CH 4 and CO 2 can be converted into high value products at low temperature directly.

对近年来 CH4 的低温活化的研究结果进行了评述，结合对 CH4 的两步反应同系化及CO2 加氢研究成果，提出了由 CH4 - CO2 低温转化直接合成 C2 +含氧化合物的两步法技术路线及催化剂体系，论证了其可能性

Compared the homogeneous enthalpic interaction coefficients of glycine in aqueous potassium chloride solutions with that in aqueous sodium chloride solutions and discussed different cations influence on the interaction of glycine in aqueous solutions. The dilution enthalpies of DMF in aqueous ethylene glycol, glycerol, glucose and sucrose solutions of various molalities have been determined using CSC4400 flow microcalorimetry at

本文选择N，N—二甲基甲酰胺为模型化合物，用流动量热法测定了298.15K下DMF在不同浓度的乙二醇、甘油、蔗糖和葡萄糖水溶液中的稀释焓，根据McMillan-Mayer理论，计算了其在不同溶剂组成下的同系焓相互作用系数，得到水溶液中多羟基化合物与酰胺的相互作用规律。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
