引 言互联网的蓬勃发展产生了许多新的网络服务要求，网络应用是不断变化的，这就要求能够在现有网络中方便地增加新的网络服务和协议，并且要求能够根据需要定制这些服务，而不需要通过漫长的标准化过程。

In spite of the expedient nature of the blood program, casualties in Korea never lacked the blood they needed, but the comment is justified concerning this war, as it was concerning World War II, that the efficient way to provide blood for combat casualties is not to wait for the need for it to arise and then to provide it, at least initially, by a series of improvisations.

虽然血液方案具有方便、实用特性，在朝鲜的伤亡人员从未出现短缺血液情况，关注这场战争的解释就像关注二战一样是合理的：对于战争伤亡最有效提供血液的方法不是等需要输血的时候才出现并供给，关键是在于战争初期有一系列的预防和随机应变的措施。

No stamp pad, inkpad, can be repeated oiling, continuous stamping, imprinting is not clear deformation; that do cover that is easy to carry and other characteristics.

Clerk: Our aluminum percolators are also quite inexpensive and convenient.

店员︰ 本店的铝制咖啡渗滤壶价格不贵，也相当方便。

Hydraulic planer the advantages of a smooth drive, the introduction of hydraulic drive, ram a uniform velocity,and can achieve variable speed; load capacity than the general mechanical transmission large Shaper;ram can be in any position to immediately stop or start;Stage movement to apply the hydraulic drive,feed rate can be in a certain range without adjustments; Machine done by hydraulic valve protection, are not too easy to damage the machine parts;Part of the oil is not easy to work wear, so long machine life;manipulating simple and convenient.

液压刨床的优点是传动平稳，由于采用液压传动，滑枕的运动速度均匀，且可实现无级调速；负荷能力比一般机械传动的牛头刨床大；滑枕可以在任何位置上立刻停止或起动；工作台的进给运动也采用液压传动，进给量可以在一定范围内无级调整；机床由液压安全阀做保护，过载时不容易损坏机床的零部件；零件在油里工作不易磨损，因而机床寿命长；操纵简单，使用方便。

New quarters information system developed after the existing school hostel information management will be greatly improved, from the artificial changes to the computer by way of low efficiency, data redundancy, prone to errors into rapid retrieval, Search convenient, high reliability and large memory capacity.

旧的手工纪录的宿舍管理方式已经不能适应高速发展的信息化时代，新的宿舍信息系统开发出来之后，学校的现有的宿舍信息管理将有很大的改观，由过去的人工方式转变为计算机方式，由效率低、数据冗余、易产生错误转变为检索迅速、查找方便、可靠性高、存储量大。

The old manual records management hostels can no longer accommodate the rapid development of the information age. new quarters information system developed after the existing school hostel information management will be greatly improved, from the artificial changes to the computer by way of low efficiency, data redundancy, prone to errors into rapid retrieval, Search convenient, high reliability and large memory capacity.

And diffraction efficiency have also been explored and analyzed both theoretically and experimentally.This kind of phase grating is rewritable and easy.

这种相位光栅制作方法简便，刻写环境要求不高，室温下相对较稳定，而且光栅系数可以方便的调整，相比相位全息制作方法容易进行大范围光栅的刻写。

Therefore, in this paper a new mechanics method is studied, i. e. a group of equations were set up and solved by the equilibrium conditions of the couple system. The transmission ratio and the meshing efficiency calculation formula were derived by this method. According to the law of conservation of energy. Hence then the above profound problems are analyzed and solved in a simple way. epicyclic gear train ; couple system ; transmission ratio ; meshing efficiency

故根据平面力偶系平衡条件可以很方便地推导出轮系传动比和啮合效率公式，与其它方法[卜3]不同之处还在于，本文根据能量守恒定律，不需分析啮合功率的流向，便可解决啮合效率的计算问题。1理论基础1.1基本周转轮系的力矩关系式图1为常用的2K—H型基本周转轮系，当轮系匀速转动工作时，根据受力平衡条件，作用在▲图l 2K_H基本轮系三个基本构件上的力偶矩应满足以下关系式[1]：兰=簇=撬㈤一1一涅稍一1一涅稍
