高分子学报 , 2006,
Abstract: 从SBR橡胶粒子出发,采用乳液原位悬浮聚合方法合成了一系列透明ABS树脂.采用小粒径SBR橡胶粒子虽然可以获得透明性良好的透明ABS树脂,但树脂的抗冲性能较差.采用大粒径SBR橡胶粒子ABS树脂的透明性明显下降.采用由粒径分别为400nm和70nm两种SBR橡胶粒子所组成的双峰粒子(指粒度分布谱上有两个峰)体系,当二者比例在4/6~6/4范围内,总橡胶粒子含量为15%~18%时,所得到的透明ABS树脂冲击强度已经达到90~120J/m,透光率超过80%.初步探讨了不同增韧体系的ABS树脂的脆韧转变关系;研究了不同粒径橡胶粒子的协同增韧效应.确定了由SBR双峰粒子增韧体系获得具有良好力学和透光性能的ABS树脂的基本条件.
纺织厂烘燥设备的节能和废热回收  [PDF]
纺织学报 , 1983,
Abstract: 本文将烘燥设备中的热能消耗,分为蒸发织物中水分的热量、加热通过的空气的热量、加热织物的热量、烘燥箱体蒸汽漏失的热量、烘燥箱体散失的热量等五部分,分别讨论了各部分热耗的计算和减低热耗的方法。最后还讨论了废热回收的问题。

宁夏医科大学学报 , 2013,
Abstract: 喻昌是清朝初年著名的医家,治学态度严谨,对中国医学的理论贡献颇多。代表作《医门法律》是本综合性的医书,既讨论病证治疗又力求证治规范,其包含"阴病论"、"中风论"、"秋燥论"等。其"秋燥论"的观点影响深远。此外,其确立了秋燥病名并强调燥证的辨证施治和首创了治燥专方,建立了中医学燥证的独特的理论体系。
苦寒化燥伤阴探究  [PDF]
戴春福
中国中药杂志 , 1995,
Abstract: 苦寒化燥伤阴探究戴春福(福建中医学院福州350003)不少学者认为如黄芩、黄连、黄柏、龙胆草及大黄等苦寒清热解毒之品有化燥伤阴之弊,不宜用于阴液已伤的温病营血分证 ̄[1~3]。有关苦寒化燥伤阴之说始自何时难以考证,但此说流传至今,严重影响了苦寒药物治疗热病的应有功用的发挥。笔者对此说提出质疑,兹对有关问题简探如下。1苦化燥之苦为苦温而非苦寒苦燥之语最早见于《内经》,如《素问·藏气法时论篇》云:“脾苦湿,急食苦以?...
中药燥性理论溯源及研究思路探讨  [PDF]
王瑾,王强,李鹏,刘斯琪,黄勤挽
中国中药杂志 , 2014,
Abstract: 中药燥性作为中药固有的性能之一,具有特定的功效和副作用,中医临床用药通过炮制、配伍等手段能够去烈存用。目前国内学者已对中药燥性进行了一定的研究,但仍存在着燥性评价指标不明确等问题。该文采用本草文献挖掘技术分析中药燥性理论的历史源流和特色,梳理现代文献明确中药燥性的研究现状和存在问题,提出中药燥性研究应该采用多学科知识进行系统综合评价的研究思路,可望进一步指导中医临床对燥性中药的应用。

Abstract: The aim of this study is to investigate the decolorization in anaerobic/aerobic biological activated carbon (A/A BAC) system. The experiment was divided into 2 stages; stage I is batch test for preliminary study of dye removal equilibrium time. The preliminary experiment (stage I) provided the optimal data for experimental design of A/A BAC system in SBR (stage II). Stage II is A/A BAC system imitated Sequencing Batch Reactor (SBR) which consist of 5 main periods; fill, react, settle, draw and idle. React period include anaerobic phase followed by aerobic phase. The BAC main media; Granular Activated Carbon (GAC), Mixed Cultures (MC) and Biological Activated Carbon (BAC) were used for dye and organic substances removal in three different solutions; Desizing Agent Solution (DAS), dye Solution (DS) and Synthetic Textile Wastewater (STW). Results indicate that GAC adsorption plays role in dye removal followed by BAC and MC activities, respectively. In the presence desizing agent, decolorization by MC was improved because desizing agent acts as co-substrates for microorganisms. It was found that 50% of dye removal efficiency was achieved in Fill period by MC. GC/MS analysis was used to identify dye intermediate from decolorization. Dye intermediate containing amine group was found in the solution and on BAC surfaces. The results demonstrated that combination of MC and BAC in the system promotes decolorization and dye intermediate removal. In order to improve dye removal efficiency in an A/A BAC system, replacement of virgin GAC, sufficient co-substrates supply and the appropriate anaerobic: aerobic period should be considered.
