《中华人民共和国防震减灾法》执法时效浅析

《中华人民共和国防震减灾法》的实施,为作好防震减灾工作提供了法律依据和保障,标志着我国的防震减灾工作已纳入法制化管理的轨道。加强防震减灾法制建设,依法管理防震减灾工作,是实现防震减灾社会功能的根本保障。在本法律条文中,关于执法时效问题没有明确规定,本文通过对该问题的浅析,希望为本法的修订和防震减灾工作深入开展提供一些参考。     

引燃点火减轻焦炉烟尘污染

土法炼焦，对大气环境污染严重。采用引燃点火无回收焦炉，操作简单，材料省，出焦优质，大大减轻了对大气的污染。本文对引燃点火无回收焦炉的结构及有关问题作了较为详细的叙述。

Dimethyl phthalate biodegradation by Dunaliella tertiolecta

Dunaliella tertiolecta has an ability to biodegrade dimethyl phthalate(DMP) was found in this study, and the average of the biodegradation rates were 11.3 mg/(L·d) and 30.5 mg/(L·d), and the average of the phthalic acid (PA) production rates were 1.5 mg/(L·d) and 3.6 mg/(L·d), for initial 100 mg/L and 300 mg/L DMP, respectively. The larger amount of accumulation by D. tertiolecta under higher DMP concentration may be responsible for the increase of biodegradation rate, and one of products of DMP biodegradation by D. tertiolecta may be PA. By fitting the process of DMP biodegradation by D. tertiolecta with a kinetic equation newly suggested, the standard deviations between calculated and observed values were 2.5 mg/L and 5.7 mg/L, respectively.

Heavy metal adsorption on the Le An River sediment —The adsorption model

In this study,the surface properties and adsorption properties of the Le An River sediment were modelled via surface complexation approach.The model parameters were determined based on the data of our potentiometric titration experiments and the metal adsorption experiments with the Le An River sediment samples.Consequently,the surface complexation models for the natural sediment,in our case the Le An River sediments,which can interpret the experimental data very well were successfully established.Three typical surface complexation models that is the constant capacitance model,the diffuse layer model and the triple layer model,were considered in this research.This work indicated that the consistency and the interdependency among model parameters together with the selection of the surface adsorbed species should be emphasized.     

光合细菌与酵母跨界融合(杂合)子发酵味精废水研究

光合细菌球形红假单胞菌（Ｒｈｏｄｏｐｓｅｕｄｏｍｏｎａｓ ｓｐｈａｅｒｏｉｄｅｓ）酿酒酵母（Ｓａｃｃｈａｒｏｍｙｃｅｓ ｃｅｒｅｖｉｓｉａｅ）细胞分别经溶菌酶和蜗牛酶脱壁形成原生质体，在聚乙二醇（ＰＥＧ）和Ｃａ＾２＋诱导下实现了真核与原核细胞的超远缘杂交，经抗菌素培养基初步鉴定，融合产物能同时在含有链霉素和制霉菌素的培养基中生长，而双亲细胞只能在含有单一抗菌素的培养基中生长，经初筛与得获得高絮弟性

生活垃圾复垦排矸场其渗滤水和腐熟后土壤特性的试验研究

为了考察生活垃圾复垦排矸场的渗滤水特性,对垃圾与矸石在三种不同堆置方式下重点考察了渗滤水pH值、COD、F~-、Cr~(6 )和全Hg浓度;并对腐熟后土壤中的有机质含量、容重、含水量及饱和水等进行了测定。试验研究表明,垃圾与矸石均匀混合堆置方式具有较好的效果。
