水－仲丁醇－碳4三元体系8MPa时的液液平衡

在国内首次建立的一套温度高达３５０℃，压力直至２０ＭＰａ的高压液液相平衡测定装置上，测定了水－仲丁醇－碳４三元体系在８ＭＰａ和４０３．１５，４２３．１５，４４３．１５Ｋ时液液相平衡数据。采用修改的Ｒ－Ｋ方程对此数据进行了理论关联。关联结果与实验数据一致。     

高氯废水中COD的测定

沿海城市以海水为工业用水,其废水经处理后,用标准方法测定COD 时,产生了几十倍甚至于上百倍的正误差,当改用研究的“高氯废水COD 测定方法”测定时,有效地消除了 Cl~-离子对 COD 测定的影响,测定结果的准确度及精密度均符合我国“环境监测技术规范”的规定。     

植物药超氧物歧化酶活性与某些性质的研究

应用NBT光还原法对23种植物药材SOD粗提液活性研究表明。供试材料全部达到200units·g~(-1)F·W的水平,13种超过300units·g~(-1)F·W,野山楂高达812.5units。酶的比活,玄参、何首乌位列前茅,超过300units·mg~(-1)protein~-,野山楂、枸杞等都在150units·mg~(-1)protein~(-1)以上。综合分析,何首乌、野山楂、玄参与枸杞等酶活性与比活都高,有开发利用的价值。植物药普遍具有Mn-SOD与Cu·Zn-SOD,本研究首先发现枸杞、宁夏枸杞、沙参和合子草具有Fe-SOD。酶粗提液的热稳定性明显优于纯化酶。     

MeV Pb离子在非晶Si中的射程离散──离子束混合和增强扩散的影响

１．０ＭｅＶ２０８Ｐｂ离子在非晶Ｓｉ中的投影射程ＲＰ和射程偏差ΔＲＰ作为注量和温度二者的函数用背散射法进行测定．注量的变化范围为５×１０１３～７×１０１４ｃｍ－２．注入是在室温和ｔ＝－１２０℃下完成的．由由实验所确定的投影射程，射程偏差与注量或温度无关，并且分别等于２９５和７２．２ｎｍ．与ＴＲＩＭ８６的计算结果相比较，发现ＲＰ的偏离为１８％，而ΔＲＰ的偏离为３６％．ＲＰ和ΔＲＰ二者与注量及温度的无关性，排除了所观察到的与ＴＲＩＭ的矛盾是由于注入期间辐射增强扩散或离子束混合效应而引起的解释。

Method for Risky Multiobjective Group Decision-Making and Its Application

The multiobjective group decision-making problem under risk is common in reality. This paper focuses on the study about risky multiobjective group decision-making problem where the index value is not certain. We give indexes classifying method and index normalizing formula of this type problem. By building objective function that minimizes general weighted distance from every alternative to the relatively best and worst alternative, the optimal membership degree of every decision-maker to every alternative can be obtained, and by building another objective function that minimizes general weighted distance from the optimal membership degree of every decision-maker to every alternative to the group optimal alternative and the group inferior alternative, the optimal membership degree of every decision-maker to every alternative can be obtained, which are both based on probability theory and fuzzy theory. Aftermost a model is established which collects group preferences. This method provides a new idea and     

Aspirin-like drugs may block pain independently of prostaglandin synthesis inhibition

Summary Using flurbiprofen, a chiral anti-inflammatory and analgesic 2-arylpropionic acid derivative, the enantiomers of which are not converted to each other (less than 5%) in rats or man, we obtained evidence that prostaglandin synthesis inhibition is primarily mediating the anti-inflammatory activity but prostaglandin synthesis independent mechanisms contribute to the analgesic effects. Thus, the S-form inhibited prostaglandin synthesis, inflammation and nociception in rats. The R-form had much less effect on prostaglandin synthesis and did not affect inflammation. It did, however, block nociception in rats almost as potently as the S-form. S-flurbiprofen, in contrast to the R-form, was clearly ulcerogenic in the gastrointestinal mucosa. These results indicate additional molecular mechanisms of analgesia and suggest the use of R-arylpropionic acids as analgesics.
