The prepared supported palladium catalyst with ultra thin fiber morphology can hydrogenate olefin and nitrobenzene hydrogenation in high efficiency. The loss of noble metal was reduced and the quality of the product was improved for formation of chemical bond between metal and polymer.

本论文以电纺丝技术为基础，利用聚丙烯腈、苯乙烯-丙烯腈共聚物、聚乙烯基吡咯烷酮和壳聚糖衍生物等为载体，制备出了负载钯的超细纤维无纺布形态催化剂，并对其催化加氢性能进行了讨论研究。

So it is significant to study the hydrolysis of MeOAc.

因此研究醋酸甲酯的水解工艺对聚乙烯醇的生产有重要意义。

Paper demonstrates the performance of IGC measurements for the diffusion of octane in polyethylene.

够用于得到大量的扩散系数。在此阐述如何通过IGC 测量辛烷在聚乙烯中的溶解程度。

In contrast,the imides derivatives of maleated polyethylene are stable for long periods of time at 160℃,and the decomposition of phenethylamine imide-,9-aminomethylphenanthrene imide-derivatives is initiated slowly at 255℃ and 280℃,respectively.

聚乙烯的化学改性已得到广泛应用，它能使PE获得新的物理化学或功能特性，如改进其表面粘合、亲水及吸湿、染色和印刷性质等，尤其在增加它与其它聚合物的相容性，制备共混材料时常常是必不可少的[1 ，2 ] 。

So extensive be used for polyethylene and PVC inapplicable compare high temperature's environment.

因此广泛用于聚乙烯和聚氯乙烯不适用的较高温度的环境。

Polyringlpyrrolidoneas a viscosity increaser is used to adjust the viscosity of the sols.When the molar ratio of PVP:Al(OC_3H_7)is up to 1:1,the viscosity of the PVP assisted sol increases from 2.3 to 31.5 mPa·s,and homogeneous,uniform and crack-free 1 mol%Er~(3+)-10 mol%Yb~(3+)codoped Al_2O_3 thin films with the thickness of 1.6μm are formed by 10 dipping and drying cycles sintered at 1000℃.

以聚乙烯吡咯烷酮为增粘剂，调节DCPA改性溶胶的粘度，PVP(K-90)：Al_3的摩尔比为1：1时，溶胶粘度由原始溶胶的2.3增加到含PVP溶胶的31.5mPa·s，仅经过10次循环提拉、干燥，1000℃烧结，制备出表面均匀完整，无开裂厚度约为1.6μm的1 mol%Er~(3+)-10 mol%Yb~(3+)共掺杂Al_2O_3薄膜。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
