"A Dream of Red Mansions", although the translation of research case studies, but in two languages, two types of Comparative Literature and cultural studies can learn a wealth of inspiration and resources to sort out the scientific method to sum up, you can make our translation Research based on language, literature and cultural comparative study on the solid foundation, in contrast to linguistics, comparative culture, literature and art aesthetics and poetics of translation has been found and so on, for the construction of translation studies and translation of the cause of the development of its own contribution to

红楼梦》的翻译研究虽属个案研究，但在对两种语言、两种文学和文化的对照研究中可以汲取丰富的灵感和资源，用科学的方法加以梳理总结，可以使我们的翻译研究建立在语言、文学和文化对照研究的坚实的基础之上，在对照语言学、对照文化学、文艺美学和翻译诗学等方面有所发现，为翻译学的建设和翻译事业的发展做出自己的贡献

Over the past decade, China scholars on the topic of organized crime more research, in the same period and other countries or regions of organized crime carried out a series of comparison. However, for the definition of organized crime still have differences of the characteristics of organized crime-related research is not very good, to the development of organized crime continues to actively explore. From the economic and social interests level policy perspective, the study of organized crime has not gone far enough. This article is from several areas to conduct in-depth research, to seek to organized crime control strategies contribution to the progress of a force.

近十年来，我国学者对有组织犯罪的专题研究较多，对同一时期与其他国家或地区的有组织犯罪问题进行了一系列的比较，但是对有组织犯罪的定义仍存有分歧，对有组织犯罪特性的有关研究并不十分充分，对有组织犯罪的发展趋势仍在积极探索，从经济利益层面和社会政策层面探讨有组织犯罪的研究仍未足够深入，本文试从这几个方面进行深入的研究，以寻求对有组织犯罪防治对策研究的进展贡献一份力量。

As the research method as concerned, this research collects materials and information from three different villages and organizes them in series village comparison way , which is a new attempt in the domestic present research of Pinghua group as well as the urbanization. Meanwhile, through this kind of comparison research, this thesis proposes the"disequilibrium change"concept in another kind meaning and points out that there would be disequilibrium change at different points in an identical social culture, which will promote the anthropology's understanding of change's diversity.

在研究方法上，本研究从三个不同的点收集资料，采用村落连环比较的方式组织材料，是目前国内有关平话人研究以及城市化研究的一次新尝试；同时，通过这种比较研究，提出另一种意义上的"非均衡"变迁的概念，指出了同一社会文化在不同点上变迁的不均衡现象，增进人类学有关社会文化变迁多样性的理解。

The soundness and completeness theorem of this method were proved at last. This part consists of the following points: 1. The properties of the indecomposable extremely simple form of LP were discussed, the theorem shown that every logical formula of LP was equals of a generalized conjunction normal form. 2. The method for judging a logical formula is a indecomposable extremely simple form or not was discussed, the necessary and sufficient conditions of a logical formula with not more than three implicative connective being a indecomposable extremely simple form was given. 3. The α-resolution fields of the indecomposable extremely simple form of LP were discussed, some elementary results were obtained. 4. The automated reasoning method based on the resolution principle of classical logic was discussed, the author given a method to describe the set of clauses by using a matrix, and translated the resolution of two clauses to column operations of this matrix.

二、关于格值命题逻辑系统LP中α-自动推理方法的研究 1、对LP中不可分极简式的性质进行了研究，证明了LP中任何一个格值逻辑公式等值于一个广义合取范式； 2、对LP中不可分极简式的判定方法进行了研究，讨论了含有不超过3个蕴涵运算的格值逻辑式为不可分极简式的充分必要条件； 3、对LP中不可分极简式的α-归结域进行了研究，得到了一些基本结果； 4、对经典逻辑中基于归结原理的自动推理方法进行了研究，给出了用符号矩阵表示子句集合的一种方法，把不同的归结过程转换成矩阵的列变换。

作者首先从研究设计的角度分析如何通过汇聚方法加强检验跨文化研究的因果关系的能力，然后分析跨文化研究中测量对等性(measurement invariance/equivalence)问题以及相关的统计方法，最后简要介绍了多层线性模型在跨文化研究中的应用、并讨论跨文化研究方法的发展趋势。

However, the consistency of theoretical promise and principle of the environmental sociology is the fundament of its research.

就这个目的，本文的研究虽然一定程度上在实证研究中对环境社会学的理论承诺和理论原则进行了表述，但是，环境社会学的理论承诺与理论原则的一致性问题是其研究的根基所在，本文只是给出了一种对此进行实证研究的可能途径，而在理论领域和实践领域此问题还有待进一步的研究。

The team, who presented their results at a joint meeting of the American Association for Cancer Research and the International Association for the Study of Lung Cancer in Coronado, California, this week, are now investigating whether their putative cancer stem cells are more resistant than run-of-the-mill cancer cells to chemotherapy or radiation, as research on other putative stem cells has suggested.

本周，在加利福尼亚州科罗纳多举行的美国癌症研究学会和国际肺癌研究学会联合会议上，该小组公布了他们的研究结果。他们现在正在研究假定的肿瘤干细胞是否像其他假定干细胞上的研究显示的一样，比普通癌细胞更耐化疗及放疗。
