Classical heaviness and an old book store in a certain bystreet within Paris where a familiar relics of poems are read our longing for the nature positioned in memories of our past is expressed in peace and freedom just like stop of flows of times.materials of motif introduced from the nature,which are felt more comfortable under warm sunrays in afternoon,are similar to unique sturdiness and shapelessness and provide convenience together with neutral colors.

在巴黎街道一个有着拿破仑时期典型装饰的老书店里面自在而平静的读着熟悉而久远的诗歌，它勾起了我们记忆深处对大自然的渴望，如同淅淅沥沥流过的时间之水。周围那些以大自然为主题的建筑物在午后温暖的阳光下显得更加生动，虽然他们笨拙而造型感不强烈，却为人们提供了方便和良好的视觉享受。

Cable reel motor torque constant tension which has the characteristics When the load increases in the motor output shaft speed will automatically come down, volume Rao assured when cable tension unchanged. Rao nature of this excellent performance closely integrated with the Volume; Cage used motor hysteresis coupling increases in size, functionality, easy installation, the constant tension similar characteristics, we can under the conditions required output torque. They can pull the cable external circumstances, hysteresis coupling protect cables; using torque motor controller to increase frequency hysteresis couplings Surge part because of the cable reel SCR converter using a new technology operation, smoothing adjustments to the motor terminal voltage, thereby ensuring that the output torque of the motor unchanged. so that the cable can smooth the road with the truck

其中力矩电机电缆卷筒具有恒张力的特点，当负载增加时电机的输出轴转速能自动随之降低，保证电缆卷饶时张力不变，这个优越的性能与卷饶性紧密结合；采用笼型电机加磁滞式联轴器具有体积小，功能全，安装维护方便，近似恒张力等特点，既可以根据工况需要输出力矩，又可以在电缆受外力拉住的情况下，通过磁滞式联轴器保护电缆；而采用力矩控制器加变频电机加磁滞式联轴节的电缆卷筒因其调压部分采用可控硅变流新技术，可以平滑地对电机的端电压进行调节，从而保证了力矩随负载的变化而改变，使电缆能平稳的跟大车的行进。

In the jig design process, mainly locates by V shape block and the support plate, depends on the straight clamp and the spring clamps, drills turns diameter two to be supposed to use long trades quickly drills the wrap, when drills turns the diameter incline hole uses the plane incline the jig body, when drills turns the diameter incline hole uses is the horizontal-type drilling machine, when face milling 2 V shape blocks and the milling cutter cannot interfere ,therefore V shape block altitude must reduce, the jig design must be convenient, be simple.

在夹具的设计过程中，主要以V形块和支承板来定位，靠直压板和弹簧来夹紧，钻拐径两孔应采用长型快换钻套，在钻拐径倾斜的孔时采用平面倾斜的夹具体，在钻拐径倾斜的孔时使用的是卧式钻床，铣面时2个V形块与铣刀不能干涉，因此V形块高度要降低，夹具设计要方便、简单。

The difference between the book and internet embodys that it is not convinient to restore and check information on book, the book is not free and newspaper needs special news writer to create, but it is easy to restore oninternet,and information on internet is almost free, anyone else could express their feeling and idea.

之间的差异书籍和互联网embodys ，这不是方便，以恢复和检查资料书，这本书不是免费的，报纸需要特殊的新闻作家创造，但它很容易恢复oninternet ，信息互联网上几乎是免费的，任何人都可以表达自己的感情和想法。

在有限长信号的小波变换中，一般说来零延拓不是一种好的边界处理方法，但对有些类别的小波，零延拓却能带来处理上的很大方便和收到良好的效果。

Versatile enough to be a pot, mug or bowl, this ultralight titanium kettle complements the Titan 2 Pot Set perfectly. The Kettle holds .85 liters of liquid and comes with a tight-fitting lid and drip-free spout for smooth, easy pouring. Team with Titan Tool Spoon for a bare-minimum "solo" cookware kit.

极强的多用途性使得这款超轻但却不失坚固的Titan 锅壶既能充当锅又能作为水杯甚至是碗来使用，从而完美的对Titan系列炊具起到了补充作用。0.85升的容积，加上紧固的锅盖和防滴漏设计使得倾倒更方便。

The goal of active networks is to obtain flexibilities so as to meet a variety of needs for network applications much better.

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。

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。

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
