查询词典 orientation

A different orientation would mean a change of earth gravity acting on flow boiling heat transfer. Based on analysis of the influence of buoyancy on flow boiling heat transfer at different orientation angle, the vertical upflow and downflow are used as ways of the arrangement of heating surface for the modeling test on earth's surface of the ...

The relationship between the orientation of tetrahedral [SO4]2- in sulfate crystals such as barite,anhydrite, epsomite and jarosite and their morphology was studied from the standpoint of crystal chemistry,and the formation inechanisin of their morphology was analysed according to the structural orientation of tetrahedral [SO4]2- and the bonding energy between [SO4]2- and metal ions [M2+] during growth.

本文从硫酸盐类晶体中负离子配位多面体的结晶方位和相互联结的稳定性出发，探讨了硫酸盐类晶体中[SO4]2-结晶方位与晶体结晶形貌之间的关系；认为[SO4]2-四面体与金属阳离子（Ba2+、Ca2+、Mg2+…）结合时，由于晶体结构和生长条件的不同，在晶体各族晶面上的叠合速率和取向不同；晶体的结晶形貌迥然有别。

Some natural science studies (psychological, biological, and genetic studies)show a biologi-cal basis for sexual orientation, which make" immutable" approach more convincing. But, social constructivists do not a-gree with this essentialist view of homosexual orientation claims. The debate between Essentialism and Constructivism andthe Politics of gay identity suggests that gay right could not get the real power from the claim "we can not help it".

自然科学关于同性恋生物基础的研究对"不可改变"提供了强有力的支持，而这种本质主义的研究遭到了社会建构主义者强有力的批判，身份政治中的这一争论提醒我们，从"我也无能为力"的诉求中，同性恋权利不能获得真正的力量。

The main researches about Chinese character recognition of vehicle license plate and its corresponding technique in this paper are as follows:(1) The pre-processing for image is essential before character recognition. This paper firstly uses the experience knowledge to give a roughly orientation,then set a carefully orientation based on Otsu arithmetic,finally get the whole clear license plate.In order to solve the problem of character extraction,the fly-back method is put forward:the experience knowledge is made the best of.(2) An algorithm of feature extraction from grayscale image based on optimization Gabor filters is proposed.

本文针对车牌汉字识别及相关技术进行研究，主要工作包括：(1)在对车牌汉字进行识别前需要进行必要的预处理工作，我们首先运用车牌的先验知识进行粗定位，然后采用Otsu阈值二值化方法等进行快速鲁棒的车牌区域细定位，获得完整、清晰的车牌轮廓，并采用回扫式字符切割方法，充分利用了车牌字符固有的特点准确找到各个字符的分割点，为特征提取奠定了基础；(2)提出一种优化的Gabor滤波器特征提取算法直接对灰度图像进行特征提取。

According to the experimental observations from Fujiwara et al, when the undercooling is low enough, the (111) silicon will be the dominant orientation in the polycrystalline silicon. As the undercooling becomes much higher, the (100) will be the dominant orientation.

根据Fujiwara等人所进行的矽晶粒竞争生长实验，当过冷度很小时，生长出的多晶矽中，(111)晶向的矽晶占了大多数；然而在过冷度较大时，(100)晶向的矽晶则为多数。

The LVZs in lower crust in North China Plain, Taihang Mountain and Shanxi Graben System present the clear NNE orientation. It is coincident with the orientation of the surface geological structures.

地壳下部的速度异常在华北平原地区、太行山地区和山西地堑系呈明显的北北东向分布，与区域地表的构造走向十分吻合。

This successful cornerstone of the University of Guelph's Orientation program takes place each year at the beginning of Orientation Week.

这一成功的基石，圭尔夫大学的定位计划地每年在开始的定位周。

This article puts forward a new conception of "THE DISEASE OF HOUSE"analysing the orientation and environment of a house meanwhile it points out that informa tion function of improper orientation and environment on human beings is the origin of this kind of disease.

本文通过剖析住屋环境与方位，提出了"房屋病"这个新概念，指出不利的环境和方位对人体的"信息作用"是产生"房屋病"的源由，从而以此用来指导建筑设计人员和住屋的使用者，真正使人们安其居、乐其业。
