Work contents1. Wafer factoryFAB is a modern plant producing chips, the main workplace for the cleanroom. Clean room is a constant temperature and humidity, temperature is 21 ° c. Relative humidity 65%. Fab clean rooms divided into the diffusion zone (furnace batch), yellow, etching, thin film areas.2. Fab features and functionality of the gas requiredDue to the manufacturing process on the need and use of many kinds of gases in semiconductor factories. We generally are based on gas properties to distinguish words. Specialty gases and gas can be divided into two broad categories. The former to use less gas. Such as SiH4, andNF3 . Which use large amounts of gas. Such as N2, andCDA . Due to a larger amount; General gas often in " bulk gas " call. The Bulk Gas. Specialty gas -Specialty Gas.2-1 Bulk GasIn the semiconductor manufacturing process, need to provide a variety of high purity gas used in pneumatic equipment power, chemicals or pressure medium is used as an inert environment, or take part in the reaction or to remove impurities, such as different functions.Because of increasingly sophisticated semiconductor production, its requests for gas purity is ever mentioned. Semiconductor factory will be briefly described below the general quality requirements and the necessary equipment for gas and its functions. 2-1-1Bulk gas products:Bulk gas Semiconductor plants can use, there are generally CDA 、GN2 、PN2 、PAr 、PO2 、PH2 、PHe 7 Species.2-1-2 Bulk gas manufacturing:<1> CDA/ICA(Clean Dry Air)Clean, dry air.CDASources taken from the air compressed by compressor dehumidifier, then by a filter or activated carbon adsorption to remove dust and hydrocarbons to supply the clean room CDA/ZCD 。

LuxS/AI-2型群体感应系统调控细菌生物被膜形成研究进展刘蕾1，桂萌2，武瑞赟1,3，李平兰1,*（1.中国农业大学食品科学与营养工程学院，北京食品营养与人类健康高精尖创新中心，北京 100083；2.北京市水产科学研究所，北京 100068；3.内蒙古大学生命科学学院，内蒙古呼和浩特 010021）摘 要：生物被膜是大多数细菌在自然状态下的一种生长方式，使菌体具有浮游态时不具有的优势。

它的形成和发展受到群体感应系统的调控，该系统是细菌依赖于群体密度而调控其生理行为的一种机制。

其中LuxS/2型自诱导物（autoinducer 2，AI-2）群体感应系统又称种间群体感应系统，广泛存在于G＋及G－菌中。

其信号分子AI-2被认为是种间通用的信号分子，参与调控多种细菌的生物被膜。

此外，目前已发现多种LuxS/AI-2型群体感应系统抑制剂，它们可以影响许多细菌生物被膜的形成。

目前研究人员已开始致力于揭示LuxS/AI-2型群体感应系统调控生物被膜形成的分子机制，这对于进一步理解LuxS/AI-2型群体感应系统与生物被膜的关系具有重要意义。

LuxS-dependent quorum sensing is a widespread system used by bacteria for cell-to-cell communication, which can regulate biofilm formation in a cell density-dependent manner. Autoinducer 2 (AI-2) produced by LuxS, is a species-nonspecific signal used by both gram-negative and gram-positive bacteria for biofilm formation. Currently, several inhibitors of LuxS/AI-2 quorum sensing have been determined to influence biofilm formation based on their anti-AI-2 communication mechanisms. Recently, there has been a surging interest in the mechanism of biofilm regulation by LuxS/AI-2 quorum sensing system, which is important to better understand the relationship between LuxS-dependent QS system and biofilm formation.Key words: biofilms; LuxS/AI-2 quorum sensing; autoinducer 2; quorum sensing inhibitor; regulation mechanism DOI:10.7506/spkx1002-6630-201619043中图分类号：Q939.99 文献标志码：A文章编号：1002-6630（2016）19-0254-09引文格式：刘蕾, 桂萌, 武瑞赟, 等.
