四甲基苯醌在氯化正丁基吡啶－AlCl＿3室温熔盐中的循环伏安行为

四甲基苯醌在氯化正丁基吡啶－ＡｌＣｌ＿３室温熔盐中的电化学行为，和室温熔盐的酸碱度有关，在碱性熔盐中，四甲基苯醌以不络合的形式存在，电极上的还原过程是一个ＥＣＥ过程；在酸性熔盐中，形成络合物ＴＱ（ＡｌＣｌ＿３）＿ｍ，络合数ｍ为１，２，３，随熔盐酸度变化，此外，醌类物质芳香环上的取代基，也影响其电化学性质。吸电子基团使还原电位正移，推电子基团使还原电位负移。     

暗管排水对滨海新垦区土壤盐分动态的影响及脱盐效果

作者在上海五四农场沿海滩涂垦区进行了为期两年的田间试验，对暗管排水条件下土壤盐分动态及脱盐效果作了监测分析和研究。试验结果表明，塑料暗管排水对降低１ｍ土体中的盐分效果明显，土壤含盐量由试验前的０．１８７％￣０．２５６％降至０．１３０％左右。发展暗管排水，对改良盐渍土和防止次生盐渍化具有重大的实践意义。     

黄浦江口氯化物预报公式的初步探讨

黄浦江是上海人民生活和生产的主要水源,咸水入侵会影响黄浦江水质,给上海带来很大的危害。本文在分析黄浦江咸水入侵规律的基础上,利用吴淞水厂1973～1979年的实测资料,选取枯季月瞬时最大氯化物值为因变量,运用多元逐步回归及相合非参数回归方法,建立了黄浦江口的氯化物预报公式,取得了比较满意的结果。

盐胁迫对三角滨藜种子萌发和幼苗生长的影响

通过NaCl溶液培养和海水浇灌处理，研究了盐胁迫对三角滨藜种子萌发和幼苗生长的影响．结果表明，随NaCl溶液浓度的提高，三角滨藜种子萌发有下降趋势，但低于140mmol／L NaCl溶液对三角滨藜种子萌发无明显影响；高浓度盐胁迫对三角滨藜的幼苗生长表现出抑制作用；低浓度盐胁迫（低于100mmol／L NaCl溶液培养或25％海水浇灌）则能促进其营养生长．     

Research on Fault Tolerant Scheduling Algorithms of Web Cluster Based on Probability

Aiming at the soft real time fault tolerant demand of critical web applications at present, such as E-commerce, a new fault tolerant scheduling algorithm based on probability is proposed. ““““““““Ib achieve fault tolerant scheduling, the primary/slave backup technology is applied on the basis of task‘s self similar accessing characteristics, when the primary task completed successfully, the resources allocated for the slave task are reclaimed, thus advancing system‘s efficiency. Experimental results demonstrate on the premise of satisfying system‘s certain fault tolerant probability, task‘s schedulabilistic probability is improved, especially, the higher task‘s self similar degree is, the more obviously the utilization of system resources is enhanced.     

Reliability Analysis of Sensor Networks

To Integrate the capacity of sensing, communication, computing, and actuating, one of the compelling technological advances of these years has been the appearance of distributed wireless sensor network （DSN） for information gathering tasks. In order to save the energy, multi-hop routing between the sensor nodes and the sink node is necessary because of limited resource. In addition, the unpredictable conditional factors make the sensor nodes unreliable. In this paper, the reliability of routing designed for sensor network and some dependability issues of DSN, such as MTTF （mean time to failure） and the probability of connectivity between the sensor nodes and the sink node are analyzed. Unfortunately, we could not obtain the accurate result for the arbitrary network topology, which is # P-hard problem. And the reliability analysis of restricted topologies clustering-based is given. The method proposed in this paper will show us a constructive idea about how to place energyconstrained sensor nodes in the network efficiently from the prospective of reliability.
