环境监理工作思路必须转变

拓宽和深化环境监理工作的思路，必须使环境监理由某环节向全过程监理转变，由重点向全方位监理转变，由静态向动态监理转变，由被动向主动监理转变，由劳动密集型向科技型转变，由执法型向执法服务型监理转变，由独立向联合监理转变，由封闭型向开放型监理转变。

Experimental determination of the kinetic rate law for the oxidation of perchloroethylene by potassium permanganate

Flushing soils contaminated with trichloroethylene (TCE) and perchloroethylene (PCE) with a permanganate (MnO₄⁻) solution has been shown to reduce the solvent content of the soil. Experiments were performed to quantify the rate at which KMnO₄ oxidizes aqueous solutions of PCE over a range of concentrations. In a series of homogeneous reactors, aqueous phase PCE concentrations were monitored over time in nine experimental trials with excess oxidant concentrations ranging from 5 to 30 g/l. Analysis of the data was performed to quantify the oxidation reaction order with respect to PCE and KMnO₄ and the reaction rate constant. The reaction between PCE and KMnO₄ was determined to be first-order with respect to both PCE and KMnO₄ with an overall specific reaction rate coefficient of 2.45±0.65 M⁻¹ min⁻¹.

Wet and dry epoch durations of spatially averaged rain rate,their probability distributions and scaling properties

This article is concerned with the notion of duration of wet and dry epochs in stochastic processes of spatially averaged (instantaneous) rain rate over a given region. Gamma, Lognormal, and Inverse Gaussian parametric families of probability distributions have been considered as candidate models for the distribution of such durations. Goodness of these model's fit to data of dry and wet epoch durations obtained from real time series of spatially averaged rain rate, has been tested with Pearson's -test. The parameters of each of these models have been estimated by maximum likelihood and method of moments, based on TOGA-COARE measurements of tropical rainfall. The hypotheses of independence and identical distribution (i.i.d.) among durations of dry or wet epochs have also been tested using a certain version of the Wald-Wolfowitz test. Finally, the effect of spatial scale on the moments of dry and wet epoch durations has also been investigated, pointing to self-similarity of the underlying random structures over space. The main result of this study is that among the three candidate models, Inverse Gaussian is the one conforming most adequately with all the classical testing criteria implemented here, and also with the newly established scaling behavior of both dry and wet epoch duration processes over space. This is a remarkable finding, considering that the Inverse Gaussian family has recently been also justified from a theoretical viewpoint as a reasonable model for the probability distributions of dry and wet epoch durations.

能源安全观助解我国《能源法》之结

中国已相继出台诸如《煤炭法》、《电力法》、《节约能源法》、《可再生能源法》等一系列与能源有关的法律法规,但严峻的能源形势使得一部能源领域的基本法的制定成为迫切需要.美国《能源政策法2005》在一定程度上对我国《能源法》的构建有很好的借鉴意义,但中国要制定《能源法》首先应结合中国的国情对《能源法》进行科学定位.能源安全观作为一种基本理念对把能源安全放在首位的《能源法》来说有着特殊重要的意义,这个基本理念将对《能源法》的基本原则和基本制度的理性建构产生深刻的影响.

室内空气中甲醛污染与防治

甲醛是室内空气中最主要的污染物质之一,对人体健康有非常大的危害.本文采用国家标准方法--酚试剂分光光度法对成都50多处房屋室内的甲醛浓度及其变化规律作了具体的分析,结果显示,总样品甲醛平均浓度为0.141mg/m3,超标率为50%,各采样点甲醛最高浓度为0.296mg/m3,超过国家标准值的2倍多.甲醛浓度水平随着时间的推移先是有一个升高的过程,然后才不断降低,所以建议延长空置时间,增加有效通风量,请有关部门检验合格后方可入住.
