For it breaks out a tendency that there is no theory in Chinese studies and thus becomes one of the representatives of "Chinese center orientation". Moreover, it guides the development of American Chinese studies.

从美国中国学社会科学化的角度看，可发现它是美国中国学发展史上的一块里程碑，打破了美国中国学发展史上理论薄弱的倾向，并成为&中国中心观&取向的中国研究的代表作之一，促进了美国中国学的发展。

In order to make the right evaluation of the state which is the consumption consume of the steam line system, we make an test of the heat loss of the steam line network. And we also probe into the heat loss of the steam line system and the factors. In order to solve the heat inefficency of the steam line system, we look into the present situation of the steam line network and the state of heat preservation. Then we found the open questions and the weak points of heat preservation. We make the evaluation and affirm the reason of the heat inefficency of the system. We adopted the combination of bench test and engineering optimization, then we screened out high-quality adiabator, and designed the best heating composition. We designed and developed the software"The analysis and optimization of energy of the steam line system in thermal production" It can offer convenience to the computational analysis of heat loss of the steam line system. It can also be used for design calculation and experimental verification of steam pipeline feasible radial-radius, so it can offer technical support for the reduce of heat loss of the system, the raise of well head steam quality and the raise of heat efficicency of the steam injection system.

为了对输汽系统的用能状况作出正确的分析评价，对输汽管线热损失进行了测试计算，对输汽系统热量损失及影响因素进行了探讨；为了解决输汽系统热效率低的问题，从输汽管网现状及管道保温状况调查入手，掌握存在的问题和保温薄弱环节，做出分析评价，确认导致系统热效率低的原因，采用室内试验与工程优化相结合的办法，筛选出优质保温材料，设计最优保温结构，同时设计开发了&热采输汽系统能量分析及优化软件&，为输汽系统热量损失计算分析和保温结构优化提供了方便，还对输汽管线合理辐射半径进行了设计计算及实验验证，从而为降低系统的热能损失，提高井口蒸汽干度，提高注汽系统的热效率提供了技术支持。
