The tetravalence vanadium was found in V2O5 gel thin films by measuring the electrical resistance change of V2O5 gel thin films with temperature, ESCA and X-ray diffraction analysis. in this paper, from miniamount redox in melting V2O5 and crystal structure, the influencing mechanism of miniamount redox on changing valence of vanadium was analyzed and discussed in detail.

通过对V2O5凝胶薄膜试样的电阻随温度的变化测试和电子能谱和X射线衍射分析发现V2O5凝胶薄膜中有四价钒的存在，本文从V2O5熔体的微量氧化还原和晶体结构的角度分析讨论了微量氧化还原影响钒离子价态变化的机理。

The exchange of the electrovalence of the cupric ion has been testified by XPS-ESCA.Graphite and chloride in the stage structure,seem to be the conductor and insulator,which form the "sandwich" structure.This special structure produced a weak chemical bond belt and provided the carrier space in the perpendicular direction to the c-axis.These factors in and vertical to the direction of c-axis together increased the electrical properties.

GICs将良导体的石墨层与绝缘体的氯化物层在分子尺度上结合起来，所形成的阶结构相当于许多导体和绝缘体层组成的&三明治&结构，产生化学键薄弱的通道，提供了垂直c轴方向的载流子通道，隧道效应和格架空间提供了载流子活动空间，这些因素共同作用使得GICs的电导率成倍增加

TGA, FT-IR, UV, WAXD and ESCA methods were used to detect both gas phase and condensed phase, deriving from decomposition of PVC. Meanwhile, the configuration of FRs was studied. Based on the experiments data, the FRs of PVC was divided into three kinds, and flame retardancy and smoke suppression mechanism mode for each kind of FRs was proposed.

根据所得实验数据的对比，将PVC的阻燃抑烟剂分为三个类别，分别建立了每一类化合物对PVC阻燃抑烟作用的分子模型，分别解释了各种实验现象，复配出两种阻燃抑烟性能最佳的阻燃抑烟剂。

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。
