PE:聚乙烯(polyethylene ,简称PE)的缩写。

聚乙烯(polyethylene ,简称PE)是乙烯经聚合制得的一种热塑性树脂。

在工业上,也包括乙烯与少量α-烯烃的共聚物。聚乙烯无臭,无毒,手感似蜡,具有优良的耐低温性能(最低使用温度可达-100~-70°C),化学稳定性好,能耐大多数酸碱的侵蚀(不耐具有氧化性质的酸)。常温下不溶于一般溶剂,吸水性小,电绝缘性优良。 

2017年10月27日,世界卫生组织国际癌症研究机构公布的致癌物清单初步整理参考,聚乙烯在3类致癌物清单中。

扩展资料:

聚乙烯化学分类:

聚乙烯依聚合方法、分子量高低、链结构之不同,分高密度聚乙烯、低密度聚乙烯及线性低密度聚乙烯。

1,低密度聚乙烯(LOW DENSITY POLYETHYLENE,LDPE)俗称高压聚乙烯,因密度较低,材质最软,主要用在塑胶袋、农业用膜等。

2,高密度聚乙烯(HIGH DENSITY POLYETHYLENE,HDPE)俗称低压聚乙烯,与LDPE及LLDPE相较,有较高之耐温、耐油性、耐蒸汽渗透性及抗环境应力开裂性,此外电绝缘性和抗冲击性及耐寒性能很好,主要应用于吹塑、注塑等领域。 

3,线型低密度聚乙烯(LINEAR LOW DENSITY POLYETHYLENE,LLDPE),则是乙烯与少量高级  -烯烃在催化剂存在下聚合而成之共聚物。

LLDPE外观与LDPE相似,透明性较差些,惟表面光泽好,具有低温韧性、高模量、抗弯曲和耐应力开裂性,低温下抗冲击强度较佳等优点。 

LLDPE应用领域几乎已渗透到所有LDPE市场。现阶段LLDPE和HDPE处于生命周期的成长阶段;LDPE则在1980代末逐渐进入发展成熟期,世界上已少有LDPE设备投产。

聚乙烯可用挤出、注射、模塑、吹塑和熔纺等方法成型,广泛应用于工业、农业、包装及日常工业中。

在中国应用相当广泛,薄膜是其最大的用户,约消耗低密度聚乙烯77%,高密度聚乙烯的18%,另外,注塑制品、电线电缆、中空制品等都在其消费结构中占有较大的比例,在塑料工业中占有举足轻重的地位。

PE 是physical ecation的缩写,意思是体育(课)

physical[英][ˈfɪzɪkl][美][ˈfɪzɪkəl]
adj.身体的; 自然(界)的; 物质的; 自然规律的;
n.身体检查,体格检查;

ecation[英][ˌedʒuˈkeɪn][美][ˌɛdʒəˈkeən]
n.教育; 培养; 教育学; 训练;
体育(physical ecation,缩写PE或P.E.),是一种复杂的社会文化现象,它以身体与智力活动为基本手段,根据人体生长发育、技能形成和机能提高等规律,达到促进全面发育、提高身体素质与全面教育水平、增强体质与提高运动能力、改善生活方式与提高生活质量的一种有意识、有目的、有组织的社会活动。随着国际交往的扩大,体育事业发展的规模和水平已是衡量一个国家、社会发展进步的一项重要标志,也成为国家间外交及文化交流的重要手段。体育可分为大众体育、专业体育、学校体育等种类。包括体育文化、体育教育、体育活动、体育竞赛、体育设施、体育组织、体育科学技术等诸多要素。

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
