东丽湖邻里中心

在承接这个项目之前，我们不知道天津东部还有东丽湖这么一大片保存完好的湿地，夕阳映照着辽阔的水面，芦苇中闪现着轻盈的水鸟。邻里中心——作为这片宝地旁边200hm^2大型低密度社区第一个登台亮相的小组团，对参与其中的所有人来说，既有动人的诱惑，又有切实的压力。     

砂浆立方体抗压强度与底模的关系

用自射线照相技术研究放射性核素在岩石和矿物上的吸附

应用自射线照相和岩相照相技术联合图象法研究了锕系元素和长寿命裂变产物在岩石和矿物上的吸附行为，直接观察到不同矿物和化学成份对核素的吸附。应用这个方法，研究了＾２３９Ｐｕ、＾２４１Ａｍ在花岗岩上的吸附，＾９０Ｔｃ在辉锑矿、锑赭石和脆硫锑铅矿上的吸附以及＾１２５Ｉ在灰硒汞矿上的吸附，得到了一些有价值的结果。

Stochastic TCP friendliness: Expanding the design space of TCP-friendly traffic control protocols

While the current definition of TCP friendliness has enabled a wide variety of traffic control protocols other than TCP, it still considerably restricts the design space of TCP-friendly traffic control protocols. For example, some multimedia streaming applications prefer a smooth sending rate on a time scale of tens of seconds, however, a UDP flow maintaining such a long smoothness time scale is naturally not TCP friendly by the current definition. In this paper, we propose an innovative method to relatively compare the degrees of TCP friendliness of different traffic control protocols, and use it to define a new class of TCP friendliness definitions, called stochastic TCP friendliness (STF). STF greatly expands the design space of TCP-friendly traffic control protocols, while still effectively maintaining the desired fairness of the Internet. To demonstrate the expanded design space, we also develop a new congestion control protocol, called TCP-friendly CBR-Like Rate Control (TFCBR), for multimedia streaming applications which do not require a high sending rate but prefer a smooth sending rate on a time scale of tens of seconds. TFCBR is stochastically TCP friendly, however, it is not TCP friendly by the current definition.     

混合溶剂对Ru(Ⅳ)萃取的研究

一、前言 在一定浓度盐酸介质中,Ru(Ⅳ)以RuCl_6~(2-)络阴离子状态存在,可被C类溶剂TOA(三辛胺)以离子缔合机制定量地萃入有机相。由实验得到在相同条件下,TOA对Ru(Ⅳ)的萃取率随稀释剂介电常数的增加而下降。

Study on diffusion welding SiCp/ZL101 with Cu interlayer

Through the vacuum diffusion welding SiCp/ZL101 aluminum with Cu interlayer,the effect of welding parame-ter and the thickness of Cu on the welded joint property was investigated,and the optimal welding parameters were putforward at the same time.The microstructure of joint was analyzed by means of optical-microscope,scanning electron mi-croscope in order to study the relationship between the macro-properties of joint and the microstructure.The results showthat diffusion welding with Cu interlayer could be used for welding aluminum matrix composites SiCp/ZL101 successfully.
