在工作过程中

The actuator of a mechanical/mechanism system often wastes a lot of energy to overcome the gravitational potential energy of the system in order to perform the essential work by the external circumstances.

机械系统之制动器在作动过程中，为了克服系统之重力因素，并在目前环境下达成工作目标，经常损失额外能量。

Concrete details are:(1) The Clap skates elevate the flexibility through the link structure of the "hinge", thus change the malpractice of traditional push-off process which mainly depends on the power of the hipbone and the knee, and thus obstruct the use of the power of ankle.

具体表现为：（1）Clap式冰刀通过"铰链"连接结构，提高了踝关节的自由度，改变了传统冰刀在蹬冰过程中主要发挥髋、膝关节的力量，而难以利用踝关节力量的弊端，在增加做功环节的同时又加大了膝关节的工作范围。

The concrete work and main contribution are as follows:(1) The index indicating transfer capability homogeneousness is defined, and the new terms like homogeneous grid, grid according with economic flow are put forward. These new concepts describe the degree in which transfer capability is utilized, and they provide the standard for ideal grid whose transfer capability and power generation dispatching economy are in phase. So, new idea is introduced in transfer capability analysis.(2) The multi-objective function with generation cost and transfer capability homogeneousness weighted is constructed. The relationship between system existing generation dispatching and transfer capability is revealed through comparative analysis between security economic dispatch and security homogeneous dispatch, and the variation rule analysis between generation cost and transfer capability homogeneousness with the change of weighting coefficient.(3) Example analyses demonstrate that the difference between specific power system with ideal instance can be identified effectively using the above concepts and method.

具体工作和贡献主要体现在：(1)定义了衡量电网输电能力均匀性分布的指标，提出均匀电网、符合经济流电网的新概念，以描述电网输电能力被利用的程度，并给出输电能力和发电调度经济性相协调的理想电网标准，在输电能力分析评判领域引入了新观点；(2)构造了发电费用与输电均匀性加权的多目标函数，通过对安全经济调度与安全均匀调度的对比分析，以及权系数变化过程中发电费用与输电均匀性的变化规律分析，揭示了系统现存发电调度与输电能力之间的依赖关系；(3)大量分析表明，利用上述概念和方法可有效识别系统在特定模式下与符合经济流电网的偏差程度。

Oneself design of the topic use number control tool machine to process center 藩 a town to process a box of body cover, impassability electricity and improvement which hope to find out a numerical words' application to process with traditional machine after the machine process realm in this design create the method that the painful machine processes, also hope passing this time designs better control and make use of a numerical words control to process center, for in the days to come of the work study much many backlog experience, pass a tutor to know industriously with oneself integrity of design process, to Chinese tradition handicraft of the machine process of the improvement have further of understanding with realize deeply;The machine of modern's processing realm is no longer a pure machine and process, it with calculator numerical turn and have inseparable contact, became 1 kind to influence place near situation mutually this a time's design to still apply a CAD etc.

本人设计的课题的用数控机床加工中心藩镇加工箱体盖，希望能在本次设计中找到数字话应用在机加工领域后与传统机械加工的不通电以及改良创痛机械加工的方法，也希望通过本次设计更好的掌握和运用数字话控制加工中心，为日后的工作学习多多积累经验，通过导师的辛勤知道和本人完整的设计过程，对中国传统手工的机械加工的改进有了进一步的了解和深刻的体会；现代的机械加工领域已不是单纯的机械加工，它与计算机数字化有着密不可分的联系，形成一种相互影响相互处近的局势本次设计还应用了CAD等等，希望为数控机械加工提供点心得谢谢

In order to assist Boost converter design, the working process of the converter at discontinuous current mode was analyzed and a nonlinear mathematical model was estabilished as well. Case study on Matlab/ Simulink was performed with binary logical variable used, the simulation result was consistent with the theoretical analysis which proveed the validitd and feasibility of the proposed model. The model could be used to assist Boost circuit design effectively and supplie a basis for parameter optimization.

为了辅助升压变换器在应用中的设计，分析了电流断续状态下Boost变换器的工作过程，建立了这种状态下的Boost变换器非线性数学模型，在结合二进制逻辑变量，建立了Simulink模块下的变换器仿真模型，研究表明仿真结果与理论分析结果一致，证实了模型的准确性和可行性，这种逻辑与模拟结合的简明通用的模型可以高效辅助Boost电路设计并为参数优选打下了基础。

WHEN I was growing up, one of my jobs was to have a pitcher of wine on the table each night.

在我的成长过程中，我的其中一项工作就是每天晚上把一壶的酒摆在桌子上。

It gets two conclusions. The first one is that the smaller the angle of the parallel joint pole is, the more quickly increasing push-force which acts on the oriented pin does. So it must try to pull out the inserting and drawing mechanism when the parallel joint pole is at the larger angle in order to reduce the extent of the inserting and drawing, i.e. trying to increase L_. The second one is that the forces which are exerted onhydraulic damper is more than the ones which are exerted on the oriented pin.

可知随着平行连杆所处的角度越小，导向销受到的推力增加得越快，所以要设法让插拔机构在平行连杆处于较大的角度时拔出，缩短插拔过程的行程，即应设法增大L_；在插拔机构的工作行程中，液压阻尼器所受到的冲击力大于导向销所受到的推力。

How people regard leisure services when their lives become better and better. The service industry consists of four unique principles:intangible, simultaneity, perishability, and heterogeneity. In addition, the service quality is very important in each industry. However; if enterprises want to stand out to face the competitive environment, they must maintain excellent relationships with their customers. But sometimes it is rather difficult to avoid service failure during the service delivery process. Therefore, it is important to do well in service recovery.

中文摘要随著人民生活水准提高，国人对於休闲产业也愈来愈重视，基於服务业的四种特性：无形性、同时性、易灭性与异质性等四个主要特性；服务品质已是每个产业均著力重视的，然而，在现今竞争激烈的环境，业者若想要能脱颖而出，必需致力於维持与现有顾客之关系；但往往在服务传递的过程中，难免会有些服务失误的发生，因此，如何做好事后的服务复原工作显得特别重要。

Its prototype can be seen in educator Johann Heinrich Pestalozzi's idea at the end of 19th century and the beginning of 20th century. Later on, due to the combined effect of many factors, such as other educators'(e.g. Georg Kerschensteiner,etc) practice and development of the theory, the evolution of Vocational Education System in the 20th century, the pressure of economic development in German, the need of f ...更多 lexible management in modern enterprises, the difficult situation of "Dual System", and the training and internship positions shortage because of the global economy and population change,"Work Process Oriented Theory" came into being in German.

在18世纪末19世纪初教育家裴斯泰洛奇的思想中即可见其端倪，后经过凯兴斯泰纳等教育家的实践与发展，并经20世纪职业学校课程体系的反复实践，到了20世纪90年代，由于德国经济发展的压力、现代企业从刚性管理到柔性管理的体制演变、"双元制"职业教育的困境以及经济全球化和人口变化带来的培训实习岗位短缺等诸多现实因素的共同作用，在德国诞生了工作过程导向思想。

In the process of simulation, the thesis also considers the module both sides potsherd part (there are no related reports in domestic and foreign), uses methods of finite difference and iteration to obtain the temperature field distribution and electricity generation performance quantitative relations under certain working condition.

在数值模拟过程中，本文把模块两端的陶瓷片部分亦考虑进去(这在国内外文献上尚无此方面的相关报道)，采用有限差分及迭代等方法，得到了一定工作条件下，模块的温度场分布和发电性能等诸多内在的数量关系。
