以TS为载体的催化剂对脱除三甲胺性能的研究

用Ti(SO4)2和硅溶胶制备TS载体。研究了以TS为载体的催化剂催化氧化脱除三甲胺的臭味。在制备TS载体的研究中考察了反应温度、钛硅比、焙烧温度、老化条件（如老化时间、pH值）等因素对载体吸附性能和比表面积的影响，并考察了不同活性组分、不同钛硅比的催化剂对脱除三甲胺的催化活性的影响。实验结果表明，添加Pd活性组分以及Ti:Si比为4：1mol的催化剂具有低温催化活性，脱臭效果好。     

Optimizing the atmospheric sampling sites using fuzzy mathematic methods

A new approach applying fuzzy mathematic theorems, including the Primary Matrix Element Theorem and the Fisher Classification Method, was established to solve the optimization problem of atmospheric environmental sampling sites. According to its basis, an application in the optimization of sampling sites in the atmospheric environmental monitoring was discussed. The method was proven to be suitable and effective. The results were admitted and applied by the Environmental Protection Bureau (EPB) of many cities of China. A set of computer software of this approach was also comuletelv comniled and used.     

Photodegradation of acetochlor in water and UV photoproducts identified by mass spectrometry

The sunlight photodegradation half-lives of 20 mg/L acetochlor were 151, 154 and 169 days in de-ionized water, river water and paddy water, respectively. When exposed to ultraviolet (UV) light, acetochlor in aqueous solution was rapidly degraded. The half-lives were7.1, 10.1, and 11.5 min in de-ionized water, river water and paddy water, respectively. Photopreduets of acetochlor were identified by gas chromatography/mass spectrometry(GC/MS) and found at least twelve photoproducts resulted from dechlorination with subsequent hydrtrxylation and cyclization processes. The chemical structures of ten photoproducts were presumed on the basis of mass spectrum interpretation and literature data. Photoproducts are identified as 2-ethyl-6-methylaniline; N, N-diethylaniline ; 4, 8-dimethyl-2-oxo- 1,2,3,4- tetrahydroquino-line; 2-oxo-N-(2-ethyl-6-methylphenyl)-N-(ethoxymethyl) acetamide; N-(ethoxymethyl)-2‘-ethyl-6‘-methylformanilide; 1-hydroxyaeetyl-2-ethoxyl-7-ethylind ole; 8-ethyl-l-ethoxymethyl-2-oxo-1, 2, 3, 4-tetrahydroquinoline; 4, 8-dimethyl-l-ethoxymethyl-2-oxo-1, 2, 3, 4-tetrahydroquinoline; 2-hydroxy-2‘-ethyl-6‘-methyl-N-(ethoxymethyl) acetanilide and a compound related to acetochlor. The other two photoproducts were detected by GC/MS although their chemical structure was unknown.

安全工程专业本科教育培养模式的探讨

本文分析了当前安全工程专业本科教育存在的一些问题，如本科基础知识教育欠系统和规范，知识结构的行业限制性过重，课程设置不甚合理等，这些问题对培养高素质安全科学人才及本专业自身的发展不利，笔者就合理的培养模式作了探讨，提出本科教育应有明确的目标，业务能力应有具体要求，专业知识结构应划分为四个层次。     

佳木斯台形变观测对东北地区几次浅震“场兆”异常的探讨

大地震在主破裂前往往行成地壳变形,高应力作用下进入峰值后的变形阶段,反映到地倾斜观测日均值曲线上,表现为固体潮形变趋势异常,这些异常能否指示远距离的地震,近年来不少研究者发现,远场前兆往往出现在对应力、应变变化反应灵敏的特殊构造部位。佳木斯台可能处于这种特殊的构造部位,对东北地区浅源地震短期前兆异常“场兆”的趋势性变化具有一定的意义。

不同状态MnO2对废水中As(III)的吸附研究

利用MnO2对含As(III)废水进行了吸附实验, 结果表明, MnO2对As(III)有着较强的吸附能力, 其饱和吸附量为44.06mg/g(δ-MnO2)和17.9mg/g(ε-MnO2), 阴离子的存在使MnO2吸附量有所下降, 一些阳离子(如Ga3+、In3+)可增加其吸附量, 吸附后的MnO2经解吸后可重复使用.
