Among the special nine pollutants, however, eight of them, including Hexachlorobenzene, N-Nitrosodi-N-propylamine, 3,3-dichlorobenzidine, 2,4,6-trichlorophenol, 2,3,4,5,6-pentachlorophenol, indeno (1,2,3-cd) pyrene, 4,4'-DDT and Heptachlor were in need of concern while another chemical: dibenzanthracene be of special concern. The sources of these chemicals were discussed and some control strategies were suggested based on the risk assessment.

结果表明，有18种有机污染物超过了USEPA的标准浓度要求，其中9种物质具有一定的生态风险，其中六氯苯、N-亚硝基二正丙胺、3，3'-二氯联苯胺、2，4，6-三氯酚、五氯酚、茚并(1，2，3-cd)芘、4，4'-滴滴涕、七氯在内的8种化合物具有一定的风险，而多环芳烃二苯并蒽需要引起更高警惕；在此基础上探讨了这些化合物的来源及作用，并提出了相应的防治建议。

The experiment shows that 2% tebuconazole(200g a i /100kg oxadiargyl),2.5%fludioxonil(200ml a i /100kg oxadiargyl)can be used for control of wheat stem smut, control effect is 94.7%and 88.3% respectively,Obvicusly,it's much higher than mose of 15% triad imefon,40%quintozene.

试验结果表明，2 %立克秀湿拌剂 2 0 0g/1 0 0kg、2 。5%适乐时悬浮种衣剂 2 0 0ml/1 0 0kg拌种对小麦秆黑粉病具有很好的防治效果，防效为 94.7%、88.3%，极显著高于对照药剂 1 5%三唑酮、40 %五氯硝基苯的防效。

Three common lipase activity determination methods including alkaly titrition method,p-nitrophenol method and copper soap method,aiming at consuming time,accuracy and repeatability,are compared.

比较了碱滴定法、对硝基苯酚法和铜皂法等三种常用的脂肪酶活力测定方法的测定时间、准确性和重复性。

Finally, N ethey[3,3 dimethyl spiralindoline naphthoxazine]was synthesized by the addition of 1 nitroso 2 naphthol also,the photochromic mechanism of the substance and its photochromic phenomenon in ethanol were studied.

报道了以苯肼和 3 甲基 2 丁酮为原料首先合成 2 ，3 ，3 三甲基吲哚，吲哚再与碘乙烷亲核取代，碱化得费舍尔碱，最后与 1 亚硝基 2 萘酚作用合成N 乙基 [3 ，3 二甲基螺吲哚啉萘并恶嗪 ]的全过程，并研究了该物质的变色机理以及在乙醇溶剂中的光致变色现

In this thesis, Water Solubility, 1-Octanol/water Partition Coefficient, molecular Total Surface Area, Aqueous Activity Coefficient, Henry Law's Constant and gas chromatogram relative retention times for biphenyl and its 209 chlorinated congeners were studies with holographic QSAR techniques and highly predictive QSAR models were developed. An internal validation (cross-validation) and external validation were performed to evaluate the predictivity and robustness of the HQSAR models. Based on these highly predictive QSARs, the corresponding data of 5 properties of all these pollutants were presented.

应用简化的响应曲面分析来建立显著的预测模型，必须要考虑到空间立体因素的影响；基于分子模拟技术的三维QSAR技术能够建立显著的预测模型，并且有利于对毒性机理的理解；而基于分子全息的QSAR技术建立了具有高度预测能力的QSAR模型，组内交叉验证和组外预测等方法证明模型具有高度的预测能力和稳健性，可以对硝基芳烃这一类分子结构、体内代谢过程和致毒机理都很复杂的污染物进行定量预测。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
