It can be speculated that the permanent charge accounts for 70%~90% of the total charge quantity; therefore, the permanent charge is the main type of the soil samples.

例如，温度从298K上升到3 13K时，表面电荷总量降低了50%左右，表面电位降低约加%，而三者的表面电荷密度降低30%左右，这可能由于温度升高导致了胶体凝聚以及离子在双电层中的分布的改变。

As a result, there were many cicatrice sculptured in faces of PET film, which were degraded with TA as the common metabolism, after one month.

通过电子显微镜观察降解后膜的表面，结果表明：通过长期驯化的F4和p.ch菌株，都能使PET膜表面产生明显刻蚀孔洞；且在富氧的条件下，以TA为共代谢基质降解PET膜，在一个月内能将PET膜表面刻蚀出较大空洞。

The results show that the most close-packed surface (111) orientation of FCC metals which have the lowest surface energies will grow preferentially, the surface energies for the all lattice surfaces increase linearly with increasing including angle between the surfaces and (111), which are consistent with the experimental and the linear muffin-tin-orbital-atomic-sphere-approximation results.

结果表明，FCC金属的密排面（111）的表面能最小，则该晶粒取向优先生长，与实验结果和第一原理的LMTO－ASA计算结果一致；各个晶面的表面能均随着其它晶面与（111）晶面的夹角的增长而呈线性增长关系，因此利用（111）面可推导出其他各面的表面能量。

Metal cock ring soft seat surface pressure to the bearing surfaces, such as the valve core and valve seat is concentric ring surface can be a double tight closure.

金属旋塞表面压向阀座环软支座表面，如阀芯和阀座环表面是同心的，就能得到双重严密的关闭。

Last,using surface points with color to describe the organ surface,and display the surface with OpenGL interface of display card.

最后用带颜色的表面点来描述器官的三维表面，利用显卡OpenGL接口对表面点集进行三维显示。

The fluffy film may fall off from Cf if the pretreat method of Cf suface was not appropriate. Boron sources was ahead loaded on the surface of Cf by in situ chemical reaction to protect the fiber from corrasion of vapor such as NH_3 and increase the combination between BN film and Cf. The measured surface area of the composite fiber increased greatly to

表面的氮化硼绒膜与碳纤维的结合程度，取决于碳纤维表面预处理的方式，先期在表面通过原位化学反应引入硼源物质，形成保护膜，可以避免碳纤维在整个反应过程中受到气相侵蚀而影响氮化硼绒膜与碳纤维的结合程度，该复合材料的比表面积大幅提高，达到96m~2／g。

Because of the cragginess of the 3-D surface, the distortion stripes appear when the common rectangular grating or sine grating is projected onto the object surface, which includes information about the 3-D surface profilometry. The images including distortion stripes are taken by CCD camera. The 2-D stripes information is got after processing these images. On the basis of mathematic reconstruction model and arithmetic, the 3-D surface profilometry data are gotten.

用普通白光将矩形光栅或者正弦光栅投影于被测物体表面上，由于物体外形凹凸等几何形状变化而在物体表面产生畸变条纹，这些畸变条纹就包含了物体表面形状的三维信息，由CCD摄像头摄取这些畸变条纹信息，对这些图像进行相应的处理，得到有关条纹中心线的二维信息，然后再根据相应的数学转换模型和重构算法对物体的轮廓进行重构，就可以得到被测物体表面的三维外形数据信息。

Single crystal planes can provide surface models of well-defined atomic arrangement.

金属单晶面具有明确的表面原子排列结构，在模型催化研究中，提供了各种表面结构模型，使深入研究表面结构与性能的内在联系和规律成为可能。

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。
