层次分析法评价濠河水质研究

介绍了层次分析法的步骤 ,以濠河水质评价为例 ,建立了濠河断面 ,污染因子层次结构模型。运用层次模型计算各断面相对权重。将各断面的单因子指数进行排序。最终确定濠河水质从优—劣的总排序 :和平桥 >北濠桥 >跃南路 >三元桥 >长桥。为污染优先控制提供技术支持     

分光光度法测定水样中铬

在ｐＨ４．４ＨＡＣ－ＮａＡｃ缓冲介质及乳化剂ＯＰ存在下，Ｃｒ６＋与二溴羟基苯基荧光酮（ＤＢＨＰＦ）显色反应生成桔红色络合物．该络合物最大吸收位于４８２ｎｍ波长处，表现摩尔吸光系数εｍａｘ＝３．４７×１０４．络合物配位比为Ｃｒ６＋：ＤＢＨＰＦ＝２：３，Ｃｒ６＋在０－１６μｇ／２５ｍＬ范围内遵守比耳定律．方法已用于水样中微量铬的测定，结果满意．     

草履虫──针杆藻群落对混合印染废水净化作用的条件实验

本文对混合印染废水的静态净化过程，进行了生物群落观察和条件实验。发现废水净化初期以大量细菌和草履虫（以 Ｐ． Ｃａｕｄａｔｕｍ为主）繁殖为特征，同时伴生着少量浮游藻类。随着净化过程的进行，细菌和草履虫数量下降，以针杆藻（以 Ｓ． ａｕｃｓ为主）为建群种的浮游藻类群落占优势。化学分析表明，净化作用与温度、光照条件及废水起始浓度有关。

Unemployment effects of climate policy

This paper models the unemployment effects of restrictions on greenhouse gas emissions, embodying two of the most significant types of short-term economic imperfections that generate unemployment: sectoral rigidities in labor mobility and sectoral rigidities in wage adjustments. A labor policy is also analyzed that would reduce the direct negative economic effects of the emissions restrictions.The politics of limiting greenhouse gas emissions are often dominated by relatively short-term considerations. Yet the current economic modeling of emissions limitations does not embody economic features that are likely to be particularly important in the short term, in particular, the politically sensitive unemployment rate. Moreover, only a few of these studies also consider policies that would offset the negative direct economic effects of emissions restrictions. For plausible estimates of the parameters, the model shows that, with the labor market imperfections, if there were no offsetting policies, the reductions in GNP in the U.S. in the first 10 years after emissions restrictions were imposed would be as much as 4%. However, if there were two policies, instead of just one: a counteracting labor market policy, as well as the emissions restrictions, the negative direct economic effects could be completely eliminated.     

重视开发非粘土砖墙体建材的负面环境影响

开发非粘土砖墙体建材应重视它们的隔声、抗震、放射性及隔热等性能是否符合技术标准,避免产生新的社会和环境问题。同时应严格技术考核,政府的倾斜政策也应合理、适度。

检测水中亚硫酸还原厌氧梭菌孢子的培养液富集法

水体中亚硫酸协还原菌的孢子，能在水中生存较长时间，容易在水池或管道中滋生，产生黑臭，可作为水体长期或周期性污染的一种指示，但目前国内尚无测定该菌的完整方法，作者建立了一种比较适合我国国情的测定方法，以国产蛋白陈替代胶胨型的水解液，结果阳性特征明显，精密度，重现性均较好。
