国内卫生陶瓷产品两个主要标准:GB/T-6952-1999《卫生陶瓷》,由国家技术监督局发布,1999年6月1日实施(以下简称为《国标》);JC/T856-2000《6升水便器配套系统》,由国家建材局批准,2000年8月1日起实施(以下简称为《行标》)。前者已经实施三年,后者也实施二年。在这期间,卫生陶瓷企业和业内专家针对这两个标准进行了广泛的讨论,提出了不少的意见和建议。笔者就自己在实际执行两个标准过程中的几个问题,谈几点看法,与国内同行商讨。1 国标和行标的异同比较这两个标准适用范围是不同的。国标适用于卫生陶瓷产品,行标适用于各类… 相似文献

High-speed photography (framing rate of 106 s-1 ) has been used to follow the formation and growth of damage in a number of oxide glasses when impacted with 1-mm-diameter steel balls at velocities of 150 m· s-1 or higher. Silicate, germanate, and borate glasses were studied in order to clarify the importance of "anomalous" vs "normal" elastic characteristics on their impact behavior. As expected it was found that glasses in these systems which are "anomalous" showed impact behavior which had earlier been seen in silica and borosilicate glass, whiie those glasses which are "normal" showed behavior similar to that shown by soda-lime silica glass. On the other hand, although B2 O3 has been characterized as "normal," its impact, as well as its quasi-static behavior, appears to put it in a class by itself. In this case, no cracking is observed during loading up to 150 m·s-1 , while radial and lateral cracking are seen during unloading. 相似文献
