So now it is a powerful theoretical formwork to explore and solve many complicated problems in natural science and engineering.

几何规划的应用几乎涉及自然科学和社会科学的各个领域，特别是许多工程设计中抽象出来的模型都是几何规划的形式，因此它己成为研究与解决自然科学与工程中许多复杂问题的一个强有力的工具；三。

The subject is the sequential reseach of the item of theory and experimentation reseach of hybrid-integrated optical acceleration seismic geophone (No. 49874031) and the item of theory and experimentation reseach of photoelectricity integrated acceleration seismic geophone imbursed (No. 40274047) by naitional neature science fund.

本文研究是国家自然科学基金资助项目&混合型集成光学加速度地震检波器理论与实验研究&(No.49874031)和&光电集成加速度地震检波技术理论与实验研究&(No.40274047)的后期研究课题，旨在将研究成功的各类干涉型光电集成加速度地震检波器推广应用。

Imbursed by the sub-item"Research on System Framework of Joint Source-Channel Coding under Wireless Circumstance"of national high-tech research and development plan(863 plan)"Digital Audio, Video Encoding, Transmission, Testing and Applying Model"(No.2002AA119010), and the great item"Research of Future Communication System Fundamental Theory and Technology (No.60496315)", the dissertation studies several key techniques of Low-Density Parity-Check Codes that were considered much in error correction codes field.

本文正是在国家高技术研究发展计划(863计划)&数字音视频编码、传输、测试与应用示范&(No.2002AA119010)的子课题&基于无线环境的联合信源信道系统框架研究&、国家自然科学基金重大项目&未来移动通信系统基础理论与技术研究(No.60496315)&等研究项目的资助下，对近年来在纠错码领域表现抢眼的低密度校验码(Low-Density Parity-Check Codes，LDPC)的若干关键技术展开了研究。

But i am afraid the effection. First lesson is not a hard lesson, but the lefts would be.

例如，自然科学的研究对象是千古不变、中外一同的，而社会科学研究的对象——人本身——则在不断发展，而且古今中外皆有不同，这与自然科学是截然不同的。

Double-frequency three-phase bridge converter in three phase power factor correction, three-phase active power filter are studied theoretically and experimentally.

本部分研究内容提出的双频变换器理论，申请人和导师合作分别于2006、2005年申请成功国家自然科学基金项目&高效率高性能双频变换器理论及其控制&(50677071)、教育部博士点基金项目&双频变换器理论及其应用&(200611012)和重庆市自然科学重点基金项目&新型高效电能变换技术理论及控制研究&(2005BA6017)，发表相关论文9篇。

With respect to the structure of modern science system, this article, based on the evolvement order of the external world, namely"from nature to human to society",puts forward a new idea that it should be framed with literae humaniores as the main body and sided with natural science and social science.

关于现代科学体系的门类结构问题，本文从客观世界的&自然—人—社会&的演化次序提出以人文科学为主体、自然科学和社会科学为两翼的新观点，并从研究对象上揭示了社会科学与人文科学的联系和区别，阐述了自然科学通过人文科学到社会科学的一体化。

Therefore,the paper borrows and introduces the concept of"mechanism"widely used asimportant dimension in the field of natural science and social science.On basis of theconcept,the topic of my PH.D dissertation was confirmed Under the topic,I argue that it ispossible to rethink about the theoretic high ground of socialism at the turn of new centuryand deepen socialism study if we take"social benign development"and"social operatingmechanism"as start of angle of looking at the past,the present and future,and regard themas the thinking framework of socialism issue and but emphasis of socialism issue on societyoperating mechanism.

为此，本文借鉴并引入了在自然科学和社会科学研究中作为重要范畴并被广泛使用的&机制&概念，确立了关于&社会主义社会良性发展运行机制&的研究主题，认为以&社会良性发展&和&社会运行机制&作为审视社会主义历史、现实与未来的新的出发点与切入口，并以这一新概念、新范畴、新视角为支点建构观察、认识、研究社会主义问题的思维范式和思路框架，将社会主义问题研究的着力点放在社会主义社会运行机制问题的探讨上，可能是世纪之交反思社会主义的理论制高点和深化社会主义研究的一个重要路径。

According to the study result of the recognizers based on Hidden Markova Model and on distance classification respectively,in this paper we introduce two handwriting recognition systems based on neural network ensemble,the comparison neural network recognition system and the permutation neural network recognition system.

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
