聚苯乙烯

Catalytic degradation of polystyrene in supercritical toluene and n-hexane using barium oxide were carried out. The results show that toluene is better.

本文以氧化钡为催化剂分别在超临界甲苯和超临界正己烷中考察了聚苯乙烯的降解过程，结果表明超临界甲苯的效果优于超临界正己烷。

When ATRP of styrene was investigated with 1-phenylethyl bromide/benzyl a,a-dibromide mixture as initiator, the GPC chromatogram shows two elution peaks and the molecular weighs of the peaks are approximately in a 2/1 ratio. It suggests that benzyl dibromide is a difunctional initiator of ATRP of styrene. The analysis of end group using 1H-NMR also proves the result above.

采用1-苯基溴乙烷／α，α-二溴化苄混合引发剂进行苯乙烯的ATRP反应时，所得聚苯乙烯的GPC谱图为双峰，分子量相差一倍，初步证明了α，α-二溴化(来源：ABf399C论文网www.abclunwen.com)苄引发苯乙烯ATRP反应时是双官能引发剂，并用~1H-NMR对聚合物结构进行分析，进一步证明了α，α-二溴化苄引发苯乙烯ATRP时是双端同时增长的。

Ideally this box should accommodate the tortoise fairly tightly, whilst still allowing for a couple of inches of insulating material all around the animal.

箱子的内部由木屑或家庭包装上经常用到的聚苯乙烯小块填充，或者也可以塞满纸片。

Full-mold casting is a technique similar to investment casting, but instead of wax as the expendable material, polystyrene foam is used as the pattern.

实型铸造是与熔模铸造类似的技术，但它用做型模的消耗材料是聚苯乙烯泡沫而不是石蜡。

From two pieces of thermoformed polystyrene that are die-cut to create individual parts.

该管理单元的盖子是由单独杯业由两片热聚苯乙烯的模切创造个人部分。

To ensure low leakage current and low dielectric absorption, the feed back capacitor should be made of a suitable dielectric material such as poly styrene, polypropylene, or Teflon.

为了保证低泄漏电流和低介电吸收，反馈电容器应当由合适的介电材料（如聚苯乙烯、聚丙烯或聚四氟乙烯）制成。

Measurements of mean residence time and penetration of submicrometer aerosols in flows in tubes were made within the range of Reynolds numbers from 0.07 to 0.26 by widening of aerosols pulses analysis of monodisperse polystyrene spheres solid particles injected in clean nitrogen flow through a diffusion battery of capillary tubes.

在Reynolds数0.07～0.26范围内，采用亚微米聚苯乙烯球形硬气溶胶粒子脉冲，测定了气溶胶粒子在毛细管扩散池组中的谱带展宽，由此获得了气溶胶在毛细管中的平均保留时间和穿透率。

This is more noticeable with certain materials (e.g. polystyrene, acetals, etc.), particularly if the mouldings are simply broken from the gates.

这对某些塑料更为值得注意（例如，聚苯乙烯，acetals等等），尤其是塑件被简单地从浇口折断时更明显。

In the early days avidin extracted from the egg, this egg avidin-alkaline-glycoprotein, and the adsorption of polystyrene carrier highly for ELISA in the background can increase.
