描述

The coherent electron micro-diffraction from a translation domain boundary perpendicular to the direction of the incident beam was studied. The qualitative and analytical descriptions are given to reveal the phenomena on the breakdown of center symmetry and an appearance of the forbidden diffraction spots.

对垂直电子束方向的畴界的特征，进行了实空间法的准动力学的理论推导，给出了对称性的定性描述，同时用动力学多层法程序对一些上下畴界进行了模拟；对出现的斑点不消光，中心对称的破损，镜面对称的破损等给出了定性的实空间法的动力学的理论的解析描述。

Statistical characteristics include Tectonic Density, Degree of Central Symmetry, Skewness Index, Degree of Tectonic Optimal Direction, Power Spectrum Density, Cubic Entropy and so on. The former four indexes are implemented in this paper; Structural characteristics show the characteristics of spatial distribution of geological bodies. In chapter four, a quantitative method for describing geological structure by using the structure "tree" is studied and implemented, including its formalized definition and the measurement of the similarity of different "trees".

统计特征有构造密度、中心对称度、失真指数、优益度、密度功率谱、方位熵等等，本文实现了前四个参数值的提取；结构特征是反映地质体空间分布的结构特点，第四章研究和实现了用"树结构"描述地质结构的定量方法，包括结构的形式化描述和结构的相似性度量。

The plateau-ravine model describes a cycle, but it also describes a metacycle-a cycle of cycles, a spiral, like the chambered nautilus.

高原-峡谷模型描述了一个轮回周期，也描述了一个元周期--也就是周期的周期，这是个螺旋，就好像鹦鹉螺上一圈圈的纹路。

Variation function,which is the core and a basic tool of geostatistics,can describe not only the spatial structure change,but also the randomicity change of the regional variable .

变异函数是地质统计学的核心内容和基本工具，它既能描述区域化变量的空间结构性变化，又能描述其随机性变化。

The sea chantey, a type of folk music, not only described the pleasures of stations' lives ashore, also but the harsh conditions of life aboard ship.

改正： 去掉 also 翻译参考：船歌，作为一种民间音乐，不仅描述了岸上快乐的生活，也描述了船上艰难的情况 21。

Introducing of product characteristic vector realizes the transformation from the descripti...

产品特征向量的引入，实现了对产品特征的自然语言描述向数学语言描述的转化；捆绑在组件上的约束和产品特征向量相关，使约束表达直观、集中，降低了知识表达的难度，并给出成功应用案例。

This is essentially the characterization of exposure and the characterization of effects.

这本质上是暴露的描述和效果的描述。

In order to improve the validity of identifi cation of digital image origin and predetermine accurately threshold of identification,a new probability density function of generalized chi square distribution is constructed within0,1 for asymmetrical distribution of noise correlation.

为了提高鉴别数字图像来源的正确性，正确设置判别阈值，针对噪声相关性的非对称分布，在0，1区间构造了一个广义chi平方分布的新函数，并提出了一种利用广义chi平方分布来描述噪声相关性的非对称分布和利用广义高斯分布来描述噪声相关性的对称分布的新方法。

The bill also describes the commodities in the shipment,the number of items in each commodity description,and the commodity's class or rate.

提单上也描述了货物的品名，每种品名描述的数量，以及货物的种类和价格。
