资料分享。IntroductionPolyesters are long chain polymers containing an ester linkage. They are used as films or fibre but also as composites, elastomers and for coating. The hyperbranched polyester has a core shell structure with tree like branches. The number of branches will determine the ratio of the molecular weight to size while the solubility and physical properties of the hyperbranched polyesters will be dictated mainly by the end groups exposed.In this application communication we analyze two hyperbranched polyesters samples by advanced size exclusion chromatography to assess the branching.

《爱一个人好难》其中有一句为何当初你选择一刀两断。老婆一直骂我真没出息，人家蹬了你，你的真心还在“为她牵绊”，活该！ 　　 　　《流着泪的你的脸》有这么一句至少还有一个人，今夜为你失眠. 老婆骂我你这个不知羞耻的，你准备为谁失眠呢？ 　　 　　《单身情歌》老婆不听我的解释，非要把“孤单的人那么多，快乐的没有几个”听成“结婚的人那么多，快乐的没有几个”。无理的她揪着我耳朵骂道：“你还敢说跟我结婚不快乐吗？” 　　 　　《我的心只可容纳你》老婆说这首歌还行，但非要我把这句“这土地，像船儿过水无痕迹，隐藏着千亿个回忆”改成“这土地，像船儿过水无痕迹，隐藏老婆一个人的回忆”，否则不让听。 　　 　　《有多少爱可以重来》这样一句：“常常责怪自己，当初不应该，常常后悔没有把你留下来。”我一听这歌，老婆就厉声骂道：“留下我一个人还不够，你还想留几个？” 　　 　　《月亮惹的祸》这句“都是你的错，轻易爱上我”是祸首。为了这句破歌词，老婆曾一把鼻涕一把泪地哭：当初是你跪下来求我，现在还说是我的错。

医学研究近年来发现左卡尼汀有许多医疗保健的新功能。现在左卡尼汀已成为全球研究开发的热门对象，在国际市场上也不断走红，销售额持续攀升，我国出口连年大幅增长。 目前，左卡尼汀在医疗上主要用于原发和继发性左卡尼汀缺乏的治疗。随着科学研究的不断发展，左卡尼汀被发现在医学治疗、营养保健、减肥健美及饲料添加方面还有许多新的作用。值得关注的是，作为一只减肥食品新资源的原料，左卡尼汀在国际市场上不断走红。 国内原料生产发展飞速 制备左卡尼汀的生产方法主要有三种：提取法、化学合成法、生物合成法。提取法最早是从肉浸膏中分离提取出左卡尼汀，近年虽有不少关于提取左卡尼汀的专利报道，但由于提取纯化的步骤较多，且产量较少，难以形成规模生产。 化学合成法最早开始于20世纪50年代，主要采取两种途径，一是直接用DL－混旋体作原料，利用拆分剂析出左旋体；二是以不同的化学物质为原料进行合成，目前工业上一般采用环氧氯丙烷为原料经过氨化、酸化等几步反应，在反应过程中进行手性化，得到左旋体。现在关于左卡尼汀的化学合成方法的研究已有几十种。

各位大侠请问有没有FDA 21CFR175 300 Resinous and polymeric coatings中文版，最近要做FDA食物接触的测试。。。。

ASTM D2247 - 11 Standard Practice for Testing Water Resistance of Coatings in 100% Relative HumiditySignificance and UseWater can cause the degradation of coatings, so knowledge of how a coating resists water is helpful for assessing how it will perform in actual service. Failure in tests at 100 % relative humidity may be caused by a number of factors including a deficiency in the coating itself, contamination of the substrate, or inadequate surface preparation. This practice is therefore useful for evaluating coatings alone or complete coating systems.Tests at 100 % relative humidity are used for specification acceptance, quality control, and research and development for coatings and substrate treatments. Some tests are used for a pass or fail determination at an arbitrary time. A coating system is considered to pass if there is no evidence of water-related failure after a period of time. Other tests are used to monitor degree of failure as a function of exposure time.谁有这个标准啊？急用。谢谢
