The segment arrangement on circular curves has proven theoretical support;the segment arrangement on transition curves,however,has no theoretical support and is usually executed by means of VMT systems equipped on shield machines.

对于圆曲线的管片排版已有了相对较为成熟的理论，而缓和曲线上的管片排版以往通常是根据盾构机VMT来选择，没有成型的理论支持，为此，结合测量理论和弯环管片的实际，探索出在缓和曲线上准确选择弯环管片理论排版的方法。

The segment arrangement on circular curves has proven theoretical support; the segment arrangement on transition curves, however, has no theoretical support and is usually executed by means of VMT systems equipped on shield machines. On basis of the relevant survey theories and the actual conditions of the turning rings, the author probes into the segment arrangement on transition curves in the paper.

The article, first and foremost, sets a theoretical framework by expatiating the relating theory ranging from the characteristics of the commonage of civil sanitation and the relationships between civil sanitation and the government or market. Secondly, along with summarizing the principles and practices at home and abroad in the field of performance evaluation of civil sanitation enterprise, the article also points out the deficiency of Shaanxi in this aspect. Additionally, it consummately construct a performance evaluation index system for Shaanxi civil sanitation according to the factual situation by using following methods such as combining qualitative analysis and quantitative analysis, basic theoretical analysis and cases application analysis.

本文首先对公共卫生的公共物品特性、市场与政府在公共卫生服务中的定位等相关理论进行了阐述，为研究奠定了坚实的理论基础；其次，在吸取国外开展公共卫生管理绩效评价先进理论和实践经验，总结我国在此方面工作不足的基础上，建立了公共卫生绩效评价模型和评价指标体系的框架；第三，运用所建立的评价指标体系的框架，分析了陕西现有公共卫生事业管理绩效评价指标体系所存在的不足，并进行了原因分析；第四，结合实际情况，运用定性分析与定量分析相结合、理论基础分析与实证应用分析相结合的方法，完善了陕西公共卫生事业管理绩效评价指标体系。

By concrescence theory, this paper makes study of the conservation of his-toric blocks -"Three Neighborhood Communities with Seven Alleys" in Fuzhou.

本研究提出愈合历史街区理论，基于此理论分析了福州历史街区"三坊七巷"的保护问题，从历史街区和古民居建筑的"初步愈合"和"造血再生"两个层面入手，提出了保护历史街区的基本理论与方法体系，对愈合理论的可操作性问题进行了探讨。

The present paper through to the value investment theory's formation and the development discussion, to the value investor behavior characteristic's elaboration, using the behavior finance theory from the expectancy theory, the flock of sheep effect, responded excessively, the reverse operation model and so on four aspects and have carried on the contrast congenially to the value investment, theoretically explained why the value investment idea does have the sophistication.

本论文通过对价值投资理论的形成与发展的探讨，对价值投资者行为特征的阐述，运用行为金融理论从期望理论、羊群效应、过度反应、反向操作模型等四个方面对价值投资与投机进行了对比，从理论上解释了价值投资理念为什么具有先进性。

The development of its theory has gone through two stages, at the first stage, its theory and practice is concentrated on the interactions of family members, and is relationship oriented; at the second stage, its theory and practice are influenced by feminism, multi-culturalism, constructivism, social constructionism and ecological systems theory, and takes on a multi-integrative characteristic.

家庭系统理论的发展经历了两个历史阶段，第一个阶段的理论和实践非常重视家庭成员之间相互作用的过程，具有关系取向的特点；第二个阶段的理论和实践因受到女权主义、多元文化主义、建构主义、社会建构论及生态系统理论的影响，呈现多元综合的特点。
