This paper discusses he feat tires of rule - based methods , template - based methods and the transformation model in machine translation , and compares their advantages and disadvantages 摘要本文讨论了机器翻译中的基于规则、基于翻译模板及转换模型的特点，分别比较了它们的优点和不足。
There are three causes for this kind of transformation model : the realistic writing mode of the poets in tang dynasty , deep influence of traditional biographies , extensive influence of the legends of tang dynasty 造成这种转换模式的主要原因有三：唐代诗人写实的创作心理，史传传统的深刻浸润和同时期唐传奇的广泛影响。
The algorithm is novel in the following aspect . first , the transformation model is directly based on camera parameter , so the pixel correspondence between the two images is precisely modeled 与以往提出的算法不同，本文提出的算法直接使用相机拍摄的物理参数来表示坐标转换模型，从而精确地表示同一视点的图像上像素之间的对应关系。
The first refers to the scope of application of the theory ; the second involves the theory of dual nature of labor ; the third involves transformation model . then the article discusses three hot issues in the discussion of the theory 第一个问题涉及到劳动价值论的适用范围；第二个问题涉及到劳动二重性学说；第三个问题是有关价值转形问题的探讨。
The retinal image segmentation , the feature points of blood vessel extraction , the feature correspondency , the transformation model of retinal image and the registration parameter optimizing methods are all the main facts studied in the paper 主要研究内容包括视网膜图像血管网络的分割、血管特征点的提取、特征对应性、变换模型以及参数优化等方面。
On the foundation of the third - party logistics formation , its development is divided into three kinds of models : traditional storage - conveyance expanding model , industry and business enterprise ' s self - management model and postal transformation model 在第三方物流形成的基础上，本文将其发展总结为三种模式：传统储运企业的扩展模式、工商企业的自营模式和邮政部门的转型模式。
Whereas the readers demand high quality services for traditional literature of library , how to excavate the traditional literature resource and let it bring into more social value and service reader have become the task of university library in the period of transformation model 摘要鉴于读者对图书馆传统文献服务的高要求，如何挖掘传统文献资源，让其发挥更大的社会价值服务于读者，成为高校图书馆面临转型时期的工作任务。
Starting from the basic point of " the type " , scholars of the sociological field in western countries pay more attention to the difference of social transformation models , and establish theories such as modernization theory , adherence theory , world system theory , globalization theory and risk theory , etc 西方社会学界从类型的基点出发来着力于研究社会转型模式的异同，形成了诸如现代化理论、依附理论、世界体系论、全球化理论及风险理论等各种观点。
To solve the problem that targets disappear rapidly when ranges increase in three dimension visual environment , an algorithm was raised to replace the rigid image perspective transformation model with geometrical and optical transformation mathematical models and the model was analyzed in detail 针对空间立体视景中靶标随距离消失过程过快的问题，提出以几何效果变化模型和光效应变化数学模型替代严格的图像透视变换模型，并对该模型进行了详细的论述和分析。
This paper discussed the coordinate transformation method of wgs84 coordinate system to 1954 - beijing gauss grid coordinate . introduced transformation model of wgs84 to beijing 54 and computing method of transformation parameter . according to different model and computing method , computed and compared with the result combine real data 本文详细讨论了wgs84大地坐标转换到北京54坐标系下的高斯平面坐标的方法，重点介绍了wgs84和北京54的空间直角坐标的转换模型及转换参数的计算方法，并根据不同的模型和计算方法结合实际数据进行计算和结果的比较，认为采用基线向量求解的四参数模型具有较高的转换精度，分区变换和提高控制点精度也能提高转换的精度。
