Results Eight species belonged to three families, two orders of rodent animals and seven species of fleas were found in this area. Rattus losea and Xenopsylla cheopis were dominant species, R.flavipectus , R.norvegicus , Suncus murinus , and Banolicota indica were familiar species. The annual average density of rodents, the infected rate with flea of rodents, index of fleas, index of X.cheopis and free flea in room were 10.58%, 28.38%, 0.7916, 0.5702 and 0.0515 respectively.

结果 合浦县鼠疫疫源地的啮齿动物共有2目3科8种，以黄毛鼠为优势鼠种，黄胸鼠、褐家鼠、臭鼩鼱和板齿鼠为常见种；蚤类有7种，以印鼠客蚤为优势蚤种；年平均鼠密度、平均鼠体染蚤率、平均蚤指数和印鼠客蚤指数分别为10.58%、28.38%、0.7916和0.5702，地面游离蚤指数为0.0515。

The logarithm difference values of partition coefficients of the compounds in butyl ether/water and in cyclohexane/water system were used for the measurement of the Lewis acidity, while the logarithm difference values of partition coefficients in trichloromethane/water and in tetrachloromethane/water system were used for the measurement of the Lewis basicity, and they were used successfully to differentiate the relative strength of Lewis acidity and basicity for 59 benzene and its derivates.

以化合物在正丁醚/水和环己烷/水溶剂体系中分配系数的对数差作为酸性指数，以其在氯仿/水和四氯化碳/水溶剂体系分配系数的对数差作为碱性指数，提出了一种新的度量有机物Lewis酸碱性的方法，按此方法成功地区分了59种苯系物Lewis酸碱性的相对强弱；并成功地将上述酸碱性指数引入定量结构—性质/活性相关研究之中，探讨了苯系物的正辛醇/水分配系数、水溶解度和土壤有机碳吸附系数等常见理化性质与其Lewis酸碱性间的相关性并建立了相应的定量模型，发现它们之间存在良好的相关性。

Although only a little financial derivatives appeared in domestic capital market. The index fund has developed for a period of time. Such as Wanjia 180 index fund which underly Shanghai 180 index and ShenZheng 50 ETF.

By using the normalized difference vegetation index extracted from CBERS-02 data and the leaf area index data obtained from field measurement, this paper analyzed the relationships between the NDVI and the LAI of total samples of meadow, marsh vegetation, shrubs, and islanded forests of the wetland vegetation in Honghe Nature Reserve of Sanjiang Plain. The linear and non-linear regression models between NDVI and LAI of different wetland vegetation types were established, and the spatial distribution of LAI in the Honghe Nature Reserve was mapped.

利用中巴资源卫星CBERS-02影像提取的归一化植被指数和同期野外实测的叶面积指数数据，分析了三江平原洪河自然保护区草甸、沼泽植被、灌丛和岛状林4种湿地植被及样本总体的NDVI与LAI之间的相关关系，建立了NDVI与不同湿地植被类型叶面积指数间的线性和非线性回归模型，并制作完成洪河自然保护区LAI空间分布图。

The results display that the thymus-index, spleen-nidex, immune globulins of IgA, IgG, IgM and alexins of C3, C4 in the experiment groups were significantly higher than those of the control group (P.05); the spleen's lymphocytes translation stimulate indexes in the experiment groups were higher than that of the control group at a significance level(P.01). The peritoneal macrophages can enhance the ability of swallowing. The ability of licking up neutral red was depended upon the dosage of drug.

The results showed that the species number of periphyton was the greatest in summer and the density of dominant species was the highest in summer and autumn, and the water quality was generally consistent with the tendency of the changes both in the indices of diversity and evenness. There were significant negative correlations between the contents of N and P in water, and the indices of diversity, evenness, algae density, total biomass, while CODcr and BOD5 did not show any significant relationship with these four biological indices.
