In plastic step sucking back is very important too. Sucking back include front sucking back and back sucking back It setting sucking back to prevent flow and line. It sets sucking back speed and pressure within 20-50% and distance within 2-5cm. TOO long distance make cyclinder reserve air and cause bubbleat next molding.

熔胶过程还有一个比较重要的环节，那就是松退，松退分前松退和后松退，其作用一般是为了防止流涎和抽丝，设定值速度和压力都在20%-50%间，设定的行程一般在2-5cm间，太长的行程可能会使料筒里面贮存空气，导致下一模出现不期望的气泡。

The feeding speed of the puller top feed is differentiable to the bottom feed without any problems.

上拖轮送布的速度是可以与下送料速度区分的。

By using FEM software we found that discharge lateral pressure is twice higher than static pressure. The effect of the dilatancy is also presented in the paper.

文中通过有限元软件模拟发现筒仓在卸料过程中侧压力值会达到静载情况下的2-3倍，同时发现材料剪涨角对筒仓压力有着重要的影响，为今后的规范修正提供了一定的依据。

The dispersibility of Si〓N〓 suspensions at various conditions is in good agreement with its colloidal behavior.

氮化硅浆料在不同条件下的分散性与其胶体特性具有很好的一致性。

From the test results the peak values and dissipation energy of each loop are calculated.

由试验结果得到了不同应变水平下的沥青混合料峰值拉伸应力值并计算了每个循环内的耗散能。

ReduceMain fractionation tower,s press drop can enhance inlet pressure of compressor.At the condition of compress ratio is invariable,it can improve system pressure、increase NTS of stabilization tower、reduce stabilize gasoline C4 ratio、improve system absorbent ability.Generic design can hardly reach the best NTS of absorber,so adding absorber,NTS can obviously increase effect so absorb. Because adding absorber'NTS can reduce system dependence on other factors,and it can not lead to the increase of the energy,so it is the best economic method of improving absorb operation effect. For desorber,double feed stream is a economical means but it need adding the NTS.

降低主分馏塔的压降，可以提高压缩机的入口压力，在压缩比不变的情况下提高系统压力；增加稳定塔理论板数，可以降低稳定汽油中C4的含量，系统的吸收效果改善；一般的设计和吸收塔的最佳板数相距较大，所以改造吸收塔的理论板数，它对提高吸收效果往往最显著，又因为改善吸收塔的理论板数会降低系统对其它因素的依赖程度，而且改善它并不增加能耗，所以改造它对提高吸收效果又是最经济的手段之一；对于解吸塔来说，双股进料的工艺很有经济效益，但它需要增加理论板数来实现。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
