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 fatty acids and waxes of Myrica rubra kernel were analyzed through GC-MS, The results showed that the yield of kernel oil was 31.10%, and there were eight fatty acids and three long-chain alkanes in the extracted composition. The main composition were Palmitic acid 28.22%, Linoleic acid 14.4%, Oleic acid 25.74%, Erucic acid 15.68%, Heptadecane 5.2%, Octadecane 5.87%, Nonadecane 4.71%. The total content of unsaturated fatty acid was 55.91% with the Linoleic acid and Oleic acid of 40.19%, these supplied a reference to its comprehensive utilization.

This was the first homeopathic remedy I ever used.

这是我第一次使用顺式治疗药。

Since hydropneumatic elements and spring constraints are usually included in mechanisms in practice, and also with the development of high-speed and high-precision mechanisms, friction can no longer be neglected.

又P'0(2)其中h；为转向速度多边形上极点夕至力P；的距离(图1)。式(2)中写成叉积形式表示取矩时有顺、逆时针的转向之别。下面再看三个例子图2、图3、图匀。

Eleven subcloned DNA fragments from the 5′- upstream region of lipA, lipC and lipF of Phanerochaete chrysosporium were assayed by using the gel mobility shift assay. The total proteins extracted from P.chrysosporium mycelia grown in Kirk medium and natural fir wood chip were used to identify the segments in these 11 DNA fragments which are controlled by some regulatory proteins.

While AcMNPV and BmNPV had no stimulatory effect in nonsensitive cell lines BmNPV hr3 has been demonstrated to increase the transcriptional activity of cislinked hel510 promoter. In this study, Sf-21, Bm-N and Hi-5 cell lines were transfected with pBmhel510luc-hr3down, and then were infected with each of AcMNPV, BmNPV and HyNPV. The results indicated that viral factors could interact with hr3 to significantly copromote the transcriptional level of hel510 promoter.
