概念；1989年GRiD公司推出第一款带有触摸式屏幕的便携电脑；1992年，微软推出了"Windows for Pen"，但两年后遭淘汰；1996年Palm研制出第一款成功应用的触笔式电脑；1997年Oracle加入微软的行列开始研究平板技术；2000年是平板电脑的重要转折点之一，比尔盖茨由2000年开始，连续两届Comdex大会上的讲话中大力倡导平板电脑；2002年，平板电脑发展史上最重要的一年，也是最忙碌的一年，该年5月，盖茨带着150台平板电脑参加微软年度CEO峰会，接着8月份，平板电脑软件向电脑制造商开放，紧接着在11月份，平板电脑正式上市，七大电脑制造商开发这一新产品，12月平板电脑中文版上市。

It can decrease the surface free energy barrier toward nucleation and accelerate the crystallization rate of PEN at high temperature.

在高温下，SB与PEN发生化学反应，生成可以起到成核作用的物质，降低了PEN的成核表面自由能位垒，提高了PEN在高温区的结晶速率。

Tono-Pen眼压计目前是唯一可用于全身麻醉状态下的眼压计，为做好围术期视力保护工作，应重视Tono-Pen眼压计在术中的推广应用，防止视力损害事件的发生。

When PEN and PET were melt blended, however, transesterification between two homopolymers would take place and the resultant product may be not crystallizable.

PET／PEN共混物在熔融共混时可能会发生酯交换反应，生成嵌段共聚物或无规共聚物，从而对PET／PEN共混物的结晶性能和热性能产生不利的影响。

It is suggested that worn surface of PEN tape by sand dust particles showed bi-fractal characteristics.Ploughing and cutting by sand particles and micro-fracture were found to be the two main mechanisms for each fractal characteristics in large and small scale.

结果表明：经过沙尘磨粒磨损的PEN薄带表面形貌表现出二重分形特征，沙尘粒子的犁沟和切削磨损及PEN材料的微观断裂是引起大尺度和小尺度区间分形特征的主要机理。

The rate constant k ,the activation energy.and induction period of the transestetifieation reaction for the PET/PEN reactive blend were obtained using a kinetic expression based on a second-order reversible reaction mechanism.

根据酯交换反应程度和不同反应温度下的诱导期探讨了酯交换反应与相容性的关系，认为PET与PEN的相容导致或增强了酯交换反应，即相容性是酯交换的必要条件；同时酯交换的发生又促进了PET与PEN的相容。
