介质特性对DBD降解苯的影响

为了提高介质阻挡放电（dielectric barrier discharge，DBD）等离子体的处理效率，研究了内外介质组成分别为：（1）石英＋石英；（2）陶瓷＋石英；（3）陶瓷＋陶瓷这3种情况下苯的降解情况。试验结果表明，在处理低浓度含苯废气时，陶瓷＋陶瓷效果最好；陶瓷（内管）＋石英（外管）在处理高浓度含苯废气时显示出优势。通过对气相产物和固相结焦产物的分析验证了DBD能有效降解苯，降解产物不会带来新的污染。进一步分析了实验条件和介质材料的变化对DBD降解苯的影响机理。     

In vitro effects of metal ions on lipid peroxidation induced by alcohol in mice liver homogenate

The study is aimed to estimate the effect of different heavy metals such as Hg2+, Cd2+, Mn2+, Cr3+, Ni2+, Se2O3(2-), As2O3 water solution and combined effects of Hg2+, Mn2+, Cr3+ on lipid peroxidation in mice liver homogenate in vitro. Lipid peroxidation was determined as thiobarbituric acid-reacting materials (TBA). We select five different concentrations of selected ions for experiments. Correlations used to identify the concentration of ions associated with lipid peroxidation. The rate of lipid peroxide formation in mice liver homogenate increased with the gradual addition of alcohol. When alcohol dose was up to 0.5 ml, the rate of lipid peroxide formation was greatest. At tested concentrations, the effects of metal ions on lipid peroxidation induced by alcohol were classified into three groups, and are as follows: (1) simulative, Hg2+. (2) inhibitory, Mn2+, Cr3+, Ni2+, Se2O3(2-). (3) ambiguous, Cd2+, As2O3 water solution. When Hg2+, Mn2+ and Cr3+ were added to the mice liver homogenate with alcohol at the same time, Hg2+, Mn2+ were the main agents for the rate of alcohol induced lipid peroxidation. The simulative effect of Hg2+ on lipid peroxidation induced by alcohol indicate that alcohol-drinkers will have further health risk when they are exposed in polluted regions than others, and Mn2+, Cr3+, Ni2+, Se2O3(2-) may act as free radical scavengers and preventive remedy for alcoholism in part. Furthermore, analysis of combined effect of Hg2+Mn2+ and Cr3+ provide us a new way to estimate the combined effect of multi-materials.

晋城市旅游气候条件及旅游舒适度特征分析研究

利用晋城所辖气象站1981年-2015年气象观测资料,分析晋城市旅游气象条件特征,用温湿指数、风效指数、穿衣指数综合指标,对晋城逐月旅游气候舒适性进行评价。分析结果表明:晋城旅游资源丰富,适宜旅游时间相对较长。晋城市区、高平、陵川、沁水旅游舒适期从4月开始至10月结束,阳城从3月延至10月。春季最佳旅游适宜地为阳城,夏季最佳旅游适宜地为陵川,5月和9月是晋城全域旅游非常舒适期。该分析结论为地方旅游发展规划和游客出行提供了依据和参考。     

基于LCA的聚乳酸快递包装环境友好性评价

以聚乳酸快递包装为研究对象,运用生命周期评价（LCA）方法对聚乳酸快递包装的原料获取、加工、使用及5种处置情景的环境影响进行比较,并采用累积能源需求（CED）方法对能源消耗情况进行分析.功能单位（1000个规模为25×35cm的聚乳酸快递袋,918kg）快递袋原材料获取、加工及使用阶段的环境影响潜能值分别为1.09×10^-9、5.64×10^-10、1.24×10^-10.海洋水生态毒性是聚乳酸快递袋环境影响的主要类型,占77%;非生物资源耗竭潜能值、人类毒性次之,分别占9%和6%.能源消耗主要类型为不可再生能源,占总能源消耗的89%,其中,快递袋使用阶段为主要贡献阶段,占比为91%.处理阶段5种处置情景中情景Ⅴ（焚烧47%,填埋13%,回收40%）对环境最为友好,通过增加焚烧和回收处置的比例,减少填埋比例对环境有着更为积极的影响.     

Stainless steel corrosion scale formed in reclaimed water: Characteristics, model for scale growth and metal element release

Stainless steels generally have extremely good corrosion resistance, but are still susceptible to pitting corrosion. As a result, corrosion scales can form on the surface of stainless steel after extended exposure to aggressive aqueous environments. Corrosion scales play an important role in affecting water quality. These research results showed that interior regions of stainless steel corrosion scales have a high percentage of chromium phases. We reveal the morphology, micro-structure and physicochemical characteristics of stainless steel corrosion scales. Stainless steel corrosion scale is identified as a podiform chromite deposit according to these characteristics, which is unlike deposit formed during iron corrosion. A conceptual model to explain the formation and growth of stainless steel corrosion scale is proposed based on its composition and structure. The scale growth process involves pitting corrosion on the stainless steel surface and the consecutive generation and homogeneous deposition of corrosion products, which is governed by a series of chemical and electrochemical reactions. This model shows the role of corrosion scales in the mechanism of iron and chromium release from pitting corroded stainless steel materials. The formation of corrosion scale is strongly related to water quality parameters. The presence of HClO results in higher ferric content inside the scales. Cl⁻ and SO₄^2 − ions in reclaimed water play an important role in corrosion pitting of stainless steel and promote the formation of scales.
