Windows PE = Windows PreInstallation Environment,Windows预安装环境,微软在2002年7月22日发布,带有限服务的最小Win32子系统,基于以保护模式运行的Windows XP Professional内核说白了就是一个微型系统。。可以安装在U盘上,如电脑系统崩溃了,可以用这个微型系统启动并维修

PE的缩写的意思是聚乙烯。
聚乙烯,英文单词是polyethylene ,发音为:英 [ˌpɒliˈeθəliːn],美 [ˌpɑːliˈeθəliːn] ,因此简称PE。
聚乙烯是一种乙烯经聚合制得的坚韧、轻便、柔软、轻质的热塑性塑料。主要用于塑料袋、食品容器和其他包装的合成。聚乙烯无臭,无毒,手感似蜡,具有优良的耐低温性能,由于其化学稳定性良好,能耐大多数酸碱的侵蚀,经常作为塑料、管材、薄膜等工业领域的原料。
扩展资料
聚乙烯的特征和性质有:
1、聚乙烯常温下不溶于一般溶剂,其绝缘电阻和耐电强度高;在较宽的频率范围内,介电常数ε和介质损耗角正切tgδ值小,且基本不受频率变化的影响,作为通信电缆的绝缘材料,是近乎理想的一种介质。
2、聚乙烯比重轻,其比重均小于1。高压聚乙烯尤为突出,约为0.92g/cm^3。
3、聚乙烯为典型的热塑性塑料,是无臭、无味、无毒的可燃性白色粉末。成型加工的PE树脂均是经挤出造粒的蜡状颗粒料,外观呈乳白色。
4、聚乙烯有优异的化学稳定性,室温下耐盐酸、氢氟酸、磷酸、甲酸、胺类、氢氧化钠、氢氧化钾等各种化学物质腐蚀,但硝酸和硫酸对聚乙烯有较强的破坏作用。
5、聚乙烯软化温度低,接触火焰时易燃烧和熔融,并放出与石蜡燃烧时同样的臭味,耐环境应力龟裂性和蠕变性较差。
