Using the KMnO4 titration method to detect the catalase activity and the sulfosalicylic acid method to detect the free proline content, the changes of catalase activity and free proline content of plants in Kaili area under air pollution were studied with the representative plants such as Camellia oleifera, Pinus massonina, Cunninghamia lanceolata, Woodwardia japonica and Dicranopteris pedata in Kaili area as research subjects.

方法］以凯里地区的代表性植物（油茶、马尾松、杉树、狗脊蕨和铁芒萁）作为研究对象，采用KMnO4滴定法测定过氧化氢酶的活性，采用磺基水杨酸法测定游离脯氨酸的含量，研究大气污染影响下凯里地区植物过氧化氢酶活性、游离脯氨酸含量的变化情况。

Vancomycin was directly coupled onto Tenta Gel S NH〓 or PEGA resin through its C-terminus. HR/MAS NMR studies indicated that conformation of PEGA-bound vancomycin was the same as free vancomycin, and Ac〓-L-Lys-D-Ala-D-Ala interacts with PEGA-bound vancomycin the same way that it interacts with free vancomycin.

本文将万古霉素C端分别连接到Tenta Gel S NH〓和PEGA树脂上，利用高分辨魔角核磁共振技术研究了万古霉素在固相载体上的构象变化以及与Ac〓-L-Lys-D-Ala-D-Ala的相互作用。

Used the PERCA method to carry on the determination to March campus environment atmosphere, had discovered the peroxy free radical signal had the obvious daily variation, the HO_2 free radical strongest about 14:00 appeared a peak value in the sunlight.

采用PERCA方法对三月份校园环境大气中的过氧自由基进行了测定，发现过氧自由基信号有明显的同变化，HO_2自由基在阳光最强的14：00左右出现一个峰值。

In order to analyze the association of the periodontitis severity with changes of the human dental pulp, one hundred caries-free and restoration-free periodontally involved teeth with different periodontic destruction were studied histologically.

为了分析牙周炎的病变程度与牙髓组织改变的关系，对100个牙体完好的具有不同牙周破坏程度的牙周炎患牙进行了组织学观察，分析牙根暴露量、牙周袋深度和牙齿松动度与牙髓病变的关系。

The experiment obtains the noon peroxy free radical density approximately 11 pptv, the observation had discovered the free radical the density has the direct ratio with the ozonedensity but to have the inverse ratio with the nitrogen dioxide density.

实验测得中午过氧自由基的浓度约11pptv，观测发现自由基的浓度同臭氧浓度成正比而与二氧化氮浓度成反比。

From the experiment discovered for the first time the dimethyl ether may substitute CO to take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and optimized the CH_3OCH_3-NO-HO_2 chemistry amplifying system determination condition, the CH_3OCH_3 best density is 1.876 ppmv, the NO best density is 1.3ppmv, and obtained this method chain length CL=124, 5 parallel determinations densities of HO_2 are the 44.0pptv, the relatively standard deviation is smaller than 4%; Although chemistry box model computed result indicated the dimethyl ether, the ethene, the propene and the ethanol all can take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and their simulation chain length all grows up compared to the CO-NO-HO_2 chemistry amplifying systems, but experiments proved the ethene, the propene and the ethanol have not suit the chain-carrying agents.

首次从实验上发现二甲醚可以替代CO作为过氧自由基化学放大系统的链传递试剂，并优化了CH_3OCH_3-NO-HO_2化学放大系统的测定条件，CH_3OCH_3的最佳浓度是1876ppmv，NO的最佳浓度为1.3ppmv，并得到了这一方法的链反应长度(CL=124)，5次平行测定浓度为44.0pptv的HO_2自由基，相对标准偏差＜4％；虽然化学盒子模式计算结果表明二甲醚、乙烯、丙烯和乙醇都能作为过氧自由基化学放大系统的链传递试剂，并且它们的模拟链长都比CO-NO-HO_2化学放大体系的链长大，但是实验证明乙烯、丙烯和乙醇不适合作为过氧自由基化学放大系统的链传递试剂。
