On the contrary, sulfonated poly(arylene thioether phosphine oxide)s, with a IEC of 1.60 meq/g, even denote a swelling of 70.1% at 80oC and thus lose most of the mechanical strength.

而前述IEC为1.60 meq/g的磺化聚芳硫醚三苯基氧膦在80oC下的溶胀率为70.1%，已经出现溶胀突变，显著丧失力学强度，其耐溶胀性能比磺化聚二氮杂萘酮醚三苯基氧膦差得多。

Apart from its unique performance properties and environmental benefits the Victrex PEEK-based honeycomb provides numerous other advantages including excellent impact resistance; unlike an aluminium or thermosetting honeycomb, PlastiCell's honeycomb will not remain deformed by accidental impacts during machining or assembly of the part and, due to the material's high temperature performance, the honeycombs can operate continuously up to 220°C (428°F, a thermoformable honeycomb core allows for the production of parts with short cycle times using an autoclave-free process. There is no size constraint as it is possible to make an endless honeycomb using PlastiCell's manufacturing process. Part size limitation is dictated by the hydraulic press platen size.

除了其独特的性能特性和环境效益外，VICTREX聚醚醚酮基蜂窝芯材还有很多其它优点，比如优良的耐冲击性，不像铝或热固性蜂窝芯材，PlastiCell蜂窝芯材不会在部件加工或安装期间由于受意外撞击而变形，因为该材料具有高温性能，（此蜂窝芯材的操作温度可连续达到220℃（428℉），生产热压成型的蜂窝芯材的周期短，不使用高压反应釜加工，没有尺寸限制，用PlastiCell工艺可以生产连续蜂窝芯材，液压模板的尺寸限制部件的大小。

In this thesis, the methods of preparating new type polyesters and siloxane- polyester copolymers were studied. And their application were discussed thoroughly.

本文研究了新型聚醚酯和有机硅改性聚醚酯消泡剂的制备方法，并对其应用进行了深入探讨。

The total production capacify is 130,000 t/y for PO plant and 110,000 t/y for PPG plant , PO is an important organic chemical materially not only can be used for the production of production of pilules and furthermore for the pr addiction of pilules and furthermore for the production of polyurethane (including rigid foam , flexible foam and elastomer etc), but also can be used for the production of non-ionic surfactant , oil-field hard emulsifier , flame inhibitor , pesticide e,I;sofoer

环氧丙烷是一种重要的有机化工原料，它不仅可以生产聚醚多元醇，进而生产聚醚酯等，它还可以生产非离子型表面活性剂、油田破乳剂、阻燃剂、农药乳化剂和润湿剂等。

The effect of solid lubricants including polytetrafluoroethylene and graphite on the friction and wear behavior of the composites was examined on the same test rig as well.

结果表明：碳纤维使聚醚砜的摩擦磨损性能得到明显的改善，春改善程度同碳纤维的长度和体积分数相关；当碳纤维的体积分数约为15％时，聚醚砜复合材料的摩擦系数及比磨损率最低；添加固体润滑剂可以使复合材料的摩擦磨损性能得到进一步改善；随着温度及外载荷的变化，摩擦系数及比磨损率表现出不同的变化趋势。

The formation of the dimple morphology is due to volume increased and transverse area unchanged during tensile process of PEEK.

韧窝的形成是由于聚醚醚酮具有高模量并在拉伸过程中未出现细颈化，而是在横截面积不变的情况下，发生了体积增大的现象。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
