Based on limiting the tensile strain at the bottom of the asphalt layer and the vertical compressive strain at the top of the subgrade, the suitability of layer thickness is checked by two criteria. One is controlling the maximum surface deflection under the design load, and the other is controlling the modulus ratio between adjacent unbound aggregate base and subbase layer.

With DGD method, the electron microscopy observation has provided new information on the process of chromatin migration. That is: Firstly, the nucleus moved toward cell wall and a picture characteristic of synizesis stage of meiosis appeared; Secdonly, the transmigration of chromatin occured through CC, and a more extensive region constituted of nuclear skeleton left behind chromatin, which was named as"clear spaces" under light microscopy; Thirdly, at the late stage of synizesis, most of chromatin had gone into adjacent cells through CC and fused into a whole, and the nuclear skeleton left in the former cell gradually mixed with cytoskeleton in cytoplasm.
DGD—包埋去包埋电镜观察表明:百合花粉母细胞中有类似核纤层的结构存在;在染色质穿壁运动过程中,首先是细胞核向细胞壁靠拢,并可留下瞬间的运行轨迹——细胞核后方出现只有细胞骨架而少有细胞器的区域;其后是染色质开始穿壁,在穿壁染色质后方细胞核内出现无染色质仅有密集的核骨架的区域,到了染色质穿壁后期,大部分核物质都已穿至相邻细胞,并彼此融合,而残余在原穿出细胞中的核骨架己逐渐与原细胞的胞质骨架融为一体。

This method is based on moving average techniques, a statistics Uis calculated and opimized within a variable-sized moving window centred at an arbitrary sample location. The optimal statistic U(r0) characterizes the entities present in an image,therefore the U-statistic method usually provide better results in geochemical pattern recognition.

The common capacitance sensor is composed of two-electrode planks which vary in shape and can be fixed in different plane of space. The driving and inductive electrode pole placed in the same plane of the uniplanar scattering-field capacitive sensor. The electric field presents scattering. As the shape of power line in the electric fields is like semicircular arc or ellipse, there is some limits in the measurement depth of uniplanar scattering-field capacitive sensor, and its penetration depth is equal to 2/3 of center distance of adjacent driving and irritable electrode pole.

Coordinate sequence method is made up of the instruct information of polygon boundary x, y coordinate. It is the easiest polygon vector encoding method. The file structure of this method is easy, but because of the polygon boundary has stored two times, it will produce data redundancy, moreover, short of neighbor threshold information; Tree index encoding method make all the boundary points digitizing, store the coordinate sequence, connect the point index to boundary line, and then connect the line index to other polygons, so as to the tree index structure has came into being. It eliminates neighbor polygons boundary data redundancy problems; Topology structure encoding method is a method which by setting up a complete topology relationship structure, resolve the neighbor threshold and island information process problem. However, it makes arithmetic more complicated and makes database bigger.
坐标序列法是由多边形边界的x,y坐标对集合及说明信息组成,是最简单的一种多边形矢量编码法,文件结构简单,但多边形边界被存储两次产生数据冗余,而且缺少邻域信息;树状索引编码法是将所有边界点进行数字化,顺序存储坐标对,由点索引与边界线号相联系,以线索引与各多边形相联系,形成树状索引结构,消除了相邻多边形边界数据冗余问题;拓扑结构编码法是通过建立一个完整的拓扑关系结构,彻底解决邻域和岛状信息处理问题的方法,但增加了算法的复杂性和数据库的大小。
