    • A method for displaying objects in a CAD system, and corresponding CAD system and computer program product. The method includes loading a graphic model with a plurality of model elements including edges and faces in a CAD system and receiving a selection of a display technique to be used on the graphic model. The method also includes classifying each model element as important or unimportant. The method also includes hiding a first subset of the unimportant model elements according to the selected display technique and adjusting the transparency of a second subset of the unimportant model elements according to the selected display technique, so that the important model elements are clearly visible with relation to the unimportant model elements. The method can produce a simplified graphic model that is displayed by the CAD system.
    • 用于在CAD系统中显示对象的方法,以及相应的CAD系统和计算机程序产品。 该方法包括在CAD系统中加载包括边缘和面的多个模型元素的图形模型,并且接收对图形模型使用的显示技术的选择。 该方法还包括将每个模型元素分类为重要或不重要的。 该方法还包括根据所选择的显示技术隐藏不重要的模型元素的第一子集,并且根据所选择的显示技术调整不重要的模型元素的第二子集的透明度,使得重要的模型元素与关系清楚可见 到不重要的模型元素。 该方法可以生成由CAD系统显示的简化图形模型。

    • New blends of fluorinated thermoplastic elastomers are disclosed that contain a two-phase composition including a continuous phase of a melt processible crystalline thermoplastic fluorocarbon resin and a dispersed phase of an amorphous crosslinked fluoroelastomer, and a dispersion-process-produced, non-fibrillating, non-melt-processible polytetrafluoroethylene (PTFE) powder. The PTFE copolymer is made up of recurring units of hexafluoropropylene, perfluoro(alkyl vinyl ether) wherein the alkyl group has 1-4 carbon atoms, and mixtures thereof. The PTFE compounds uniformly with the two-phase composition without forming visible agglomerates. Poly(phenylene sulfide) powder can be added to the blend to increase melt flow characteristics. Additionally, an uncured fluoroelastomer can be incorporated into the blend to enhance its mechanical properties. The preparation of the fluorinated thermoplastic elastomers involves dynamic curing of the fluoroelastomer in the presence of the molten thermoplastic fluorocarbon resin and the non-melt-processible PTFE resin.
    • 公开了氟化热塑性弹性体的新共混物,其包含两相组合物,其包括可熔融加工的结晶热塑性氟碳树脂的连续相和无定形交联的含氟弹性体的分散相,以及分散工艺生产的非原纤化非共沸 可熔融加工的聚四氟乙烯(PTFE)粉末。 PTFE共聚物由六氟丙烯的重复单元,烷基具有1-4个碳原子的全氟(烷基乙烯基醚)及其混合物组成。 PTFE化合物与两相组合物均匀地形成,而不形成可见的附聚物。 可以将聚(苯硫醚)粉末加入到共混物中以增加熔体流动特性。 此外,未固化的含氟弹性体可以掺入共混物中以增强其机械性能。 氟化热塑性弹性体的制备涉及在熔融的热塑性氟碳树脂和不可熔融加工的PTFE树脂的存在下的含氟弹性体的动态固化。
