Using a nonperturbative scattering theory developed by Guo,Aberg and Crasemann the angular distributions of electrons in above threshold ionization of Krypton atoms irridated by a bichromatic phase-controlled laser field of linear polarizations is studied. The bichromatic phase-controlled laser field is composed of a sequence of identical one-cycle laser pulses.

采用基于Guo， Aberg 和Crasemann发展的强激光场中的非微扰量子散射理论，研究了线偏振双色激光场中氪原子阈上电离的光电子角分布，双色激光场由一系列相同的单周期激光脉冲组成。

The formation, texture and some properties of cyanoethyl cellulose/dimethyl aceta-mide mesomorphic solutions were studied.

本文利用Abbe折射仪，热台偏光显微镜，小角光散射等方法研究了氰乙基纤维素/二甲基乙酰胺液晶溶液的形成，形态结构和某些性质。

After analyzed the advantages and disadvantages of nephelometric methods, according to the topic, select the scattering-light method,and put the light detector at 90°to decrease the effect of stray light.

在分析和比较其优缺点后，针对课题要求选择散射光式测量方法；并选择以90°角作为检测角度，以减小杂散光的影响。

The porosity and pore size distribution of HVFA pastes and concretes were determined by autoscan porosimeter. The results show that excessive fly ash content and comparatively high water-cementitious materials ratio will cause a big increase in porosity and harmful pore in HVFA pastes.

首次把X射线小角散射技术用于测定高掺量粉煤灰水泥浆体气孔—固体界面的分形维数，并就粉煤灰掺量、水胶比对气孔—固体界面分形维数的影响进行了分析，发现过高的粉煤灰掺量和较大的水胶比均会使分形维数大幅度增加。

This is because the fact that, without the anchoring effect of the surface alignment, the cells are always full of unapparent and small focal-conic-like defects; thus no CCLE can be measured due to strong scattering.

因为样品没有表面配向提供的锚定力，样品内充满许多不明显，但是类似focal conic的缺陷，这会造成强烈的散射，也因此无法量测到彩色锥角雷射讯号。

Crystallization behavior of undrawn and hot drawm PET film with random orientation in chain segments and high orientation in the global sense has been compared using SAXS and WAXD.

采用小角和广角X-散射法比较了未拉和热拉PET膜在结晶性能方面的差别，热拉试样在分子链段的小尺度范围内基本上是无规取向，而在分子链的大尺度范围内却是高度取向的。

As compared with undrawn PET film, the hot drawn PET film showed shorter crystallization induction period, faster development of long period, anisotropic in SAXS and WAXD patterns, with considerable thermal contraction along the direction of drawing and small lengthening in the direction of drawing during crystallization.

研究结果表明：热拉PET膜的结晶诱导期较短，长周期发展得较快，结晶后小角X-线散射表现出明显的各向异性，在热处理过程中先出现显著的热收缩，随后又表现出结晶伸长现象，这些都和未拉试样有明显的差别。

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。
