The fourth chapter talks about the weft carrier, in this part, we mostly introduce the big gripper shuttle in the comparative way and not only analyze the structure but also analyze the stress of the fatigable parts. In the fifth chapter, the shuttle box is our research emphasis, we start with the design principle and analyze its structure and the logic of the action of the parts. The sixth chapter discusses the shoot mechanism, builds its theory model and analyzes its law of motion from the view of kinematics and kinetics during the wefting. And then, we can consider the hydraulically shoot mechanism and comprehend its principle and some special parts. Subsequently, the content is about the flying of a shuttle, because the course of the flying of a shuttle is very complex, it is necessary to study the shuttle according to mechanics and to analyze its course of motion and its change of speed from the view of energy.

第五章谈的是梭箱，这部分从梭箱的设计原理入手，从结构的角度对梭箱进行分析，考虑到梭箱上各执行件间的动作存在一定的逻辑关系，还对执行件动作时间与控制作出论述，从中可以看出重型宽幅织机所独有的特性；第六章论述投梭机构，先构造出投梭机＿重型宽幅织机引纬机构与梭箱的设计＿构的弹性理论模型，从动力学的角度剖析投梭规律，随后分析液压式投梭的工作原－－理和一些特型元器件；第七章论述梭子的飞行运动，考虑到梭子飞行运动的复杂性，我们把梭子飞行运动划分为三个阶段，然后分阶段介绍其运动规律，在对梭子进行＿运动分析的同时还详细分析它的受力情况，在这一章的最后，我们对影响梭子飞行＿的因素也作出了讨论；顺沿这一过程，即是第八章对制梭机构的论述，在这一部分，、主要研究制梭过程与制梭力的情况，同梭子飞行过程一样，制梭过程也分为三个阶段，就每个阶段而言，我们都对其进行受力与运动方面分析，同时也就一些容易出现的问题作出讨论；最后两章是对纬纱交接机构和纬纱的退绕与张力控制作出讨＿论，鉴于这两部分不存在复杂的动力学方面的问题，论述重点便放在结构与原理的分析上面，包括分解纬纱交接机构，解析其动作过程，介绍储纬与纬纱张力的一些情况。

The following cases, to go with locator: 1, medium pressure high pressure big time; 2, valve diameter is largeForged Gate, Globe, Check Valves (DN 00); 3, high or low temperature control valve; 4, the action necessary to raise the speed control valve; 5, using standard signal, the operation of non-standard spring when the implementing agency (20 ~ 100KPa spring outside the range); 6, when used for sub-process control; 7, when the valve to achieve the reverse action (air to close each open-type gas conversion); 8, need to change the valve''s flow characteristic time (you can change the positioner cam); 9, no spring actuator or piston actuator, the proportion of action to achieve the time; 10, electrical signals to operate pneumatic actuator must Distribution - gas valve positioner.

下面所开列情况下，要配定位器：一、介质压力高、压差大的时辰； 2、调节阀口径大时（DN00）； 3、高温或低温调节阀； 4、需要提高调节阀的动作速度时； 5、用标准旌旗灯号、操作气动管路截止阀非标准弹簧的执行机构时（20～100KPa以外的弹簧范围）； 6、用于分程节制时；七、使阀门实现逆向动作时（气关式和气开式互相转换）； 8、需要改变阀的流量特性时；九、无弹簧执行机构或活塞执行机构，要实现比例动作时； 10、用电旌旗灯号去操作气动执行机构时，必须配电-气阀门定位器。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
