And call it the craft course. In the course of making the craft , is it confirm every erector location and worker step that process need this of process to want, the locomotive of processing , this process , and the entering the giving amount of the lathe, cut

在制定工艺过程中，要确定各工序的加工顺序和该工序需要的工步，加工该工序的机车及机床的进给量，切削深度，主轴转速和切削速度，该工序的夹具，刀具及量具，还有走刀次数和走刀长度，最后计算该工序的基本时间，辅助时间和工作地服务时间。

I passed many years of professional training and theory into the university to enhance knowledge, according to campaign biological mechanics, sports psychology theory, from a shot-put athletes Huabu final forceful convergence with the key elements of starting and design a closely related special training methods, and orderly portfolio formation against the strong, effective and comprehensive system as a whole marked.

本人通过多年的专业训练和进大学后理论知识的加强，根据运动生物力学、运动心理学原理，从构成铅球运动员滑步与最后用力衔接的关键要素出发、设计了与之密切相关的专项训练手段，并进行有序的组合，形成针对行强、且综合功效显著的系统整体。

The thesis will further illustrate the precise application of formulaic expressions in foreign trade contract, and it also shows the importance of mastering the formulaic expression on precisely writing a foreign trade contract, through combining with the false usage of formulaic expressions in foreign trade contract and their analysis.

本文还进1步说明外贸合同套语的正确运用，并结合外贸合同套语的错误用法及其分析，从而说明掌握外贸合同套语对正确撰写外贸合同的重要性。

By simulation, the optimal operation conditions were gained in every step in the separation process, and polymerization-class isoprene was gained by the process. And to improve the economy of process, the process was studied by simulation, 99% cyclopentene and 1, 3-pentadiene were gained by continuous separation process. All were the base of the process industrialization.

通过模拟研究，得到分离各步的最佳塔高，进料位置和各种操作条件；并进行了全流程的模拟优化得到聚合级的异戊二烯的各种工艺参数；通过模拟研究对分离工艺进一步深化，得到了从C5中分离出环戊烯和间戊二烯的优化工艺条件，对工艺经济性进一步优化，给过程工业化提供了依据。

They were tied head to tail, four of them, and they heaved along to where a lane branched off from the highroad, planting their great hoofs floutingly in the fine black mud, swinging their great rounded haunches sumptuously, and trotting a few sudden steps as they were led into the lane, round the corner.

它们四匹一组，从头到尾被栓在一起，被牵到大路上岔出来的一条小路上。它们肆无忌惮地把蹄子踏进脚下乌黑的稀泥中，抖动着巨大浑圆的屁股。当被带到拐弯处时，又疾走几步。

The hydrogenation and methyl esterification of furoic acid over Pd-Ni/γ-Al2O3 catalysts was investigated in fixed bed micro-reactor under different conditions such as reaction temperature,pressure,H2 space velocity,space velocity of furoic acid and methol,ratio of H2 and furoic acid and so on.

以糠酸、甲醇、氢气为原料，采用连续流动固定床微反应器，Pd-Ni/γ-Al2O3为催化剂，使糠酸一步加氢甲酯化生成α-四氢糠酸甲酯。研究了反应的温度，压力，气、液体流速，进料流量等因素对催化反应的影响。结果表明：在1.5MPa，250℃，氢气空速3300 h-1，液体空速3.0 h-1(氢油比为50)时，糠酸转化率为96.6%，四氢糠酸甲酯的选择性97.2.0%，产率94.0%。催化剂稳定性较好，连续运转280小时后未见活性下降。该反应体系活性高，选择性好，反应压力低，催化剂性能稳定，操作简单，产物易分离

The findings, which appear in the December issue of the Journal of Inestigatie Medicine, are significant because it is one step closer in soling the mystery of whether nanoparticles are iable liing forms that can lead to disease -- in this case, kidney stones.

发表在12月份《医学调查杂志》上的一片文章报告了具有重要意义的发现，因为这些发现使我们离解决一个迷更进了一步，那就是毫微粒究竟是不是以能生长发育并能导致肾结石发病的活体形式存在的。

Personally, he had no intention of ever coming back here; he'd tell the staff where to find Crabbe's body and then he'd make sure it was interred correctly, but he, himself, would never step foot in this room ever again.

就个人品性而言，他没有再回到这里的意图，他可以告诉工作人员克拉布的尸体在哪，并保证他们能够找到正确的入口。但是，在他内心深处，绝不想再踏进这房间一步了。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
