结合工程实例就乳化沥青厂拌冷再生配合比设计探讨

冷再生配合比设计一直处于模糊的摸索阶段,对工程现场铣刨RAP材料进行了冷再生配合比设计,既利用土工基层配合比设计中最大干密度和最佳含水量的理念,也充分结合热沥青混合料的配合比设计中马歇尔空隙率、稳定度、劈裂强度等理念,确定了厂拌乳化沥青冷再生配合比。即RAP料占87%,石屑(0～5mm)占13%,水泥掺量为1.5%,最佳含水率7%,最佳沥青用量为2.5%。     

光束的非交迭效应对极化干涉仪的影响

从高斯光束基本理论出发,分析了双光束的非交迭效应对ＭａｃｈＺｅｈｎｄｅｒ极化干涉仪性能的影响,提出了改善极化干涉仪性能的途径,并在实验中得到了验证．用自制的有衬底的线栅极化器组装成的ＭａｃｈＺｅｈｎｄｅｒ极化干涉仪,在波长为３３７μｍ（８９０ＧＨｚ）的条件下,测得调制比优于１９ｄＢ,插入损耗小于１ｄＢ．     

硒蛋白分子生物学及其生理功能研究进展

在硒蛋白特别是硒酶的活性中心发现含有硒半胱氨酸,说明硒对硒蛋白的结构和硒酶的活性有着重要意义,研究发现,硒半胱氨酸是参入到蛋白质分子中的第21种氨基酸,硒是唯一受基因调控的微量元素,本文对硒蛋白分子生物学及其生理功能研究进展进行综述。     

模型NEPE推进剂燃烧转爆轰实验研究

建立了推进剂燃烧转爆轰（ＤＤＴ）的实验系统，分别利用弱约束和强约束对ＮＥＰＥ推进剂的ＤＤＴ过程进行测试，得到了其速度增长规律和诱导爆轰距离，并对强弱约束的ＤＤＴ数据进行了比较．实验表明，在弱约束条件下由于侧向稀疏作用，推进剂较难产生由燃烧到爆轰的转变，一旦形成爆轰，稳定爆速将不受约束强度的影响．     

The Optimum Model and Its Decision Support System of Coal Quality Balance

1　 Coal Quality Balance and Its Significance[1]Coal quality balance is to make a comprehensive plan concerning excavation steps and coalamount disposition of different coal seams based upon the natural coal-preservation stateand its relation with mining engineering in the three dimensional space so as to have thequality of coal excavated from different districts blended and coordinated the greatestextent possible and ensure the coal quality uniformity and stability,thus raise economicand soc…     

Agent-oriented Aid-modeling for the Distributed Activity Network

1　 IntroductionModern system characters distributed problem solving from the view of new generation ofDSS.Thus,traditional DSS(P.Sage,1 992 ) will separate the system into4 main parts atdifferent allocation,so that it needs an environment of information technologies (R.Blanning,1 995) and the supportoforganizational connectivity(M.Jeusfeld,1 997) .Atthesame time,distributed decision processing requires coalescent problem modeling andcollaborated decision.The distributed problem solves in…
