Pure-remote sensing information models are free of the numerous distributional parameters that are difficult to obtain in vast area. The following sections are included in the study.(1) The VCI and SVI based on time-series NDVI data are used to analyse regional drought and the following results were reached: As the vegetation growth status index, the response of VCI and SVI to precipitation was land cover type, temporal and site specified. So VCI and SVI have little information about drought when used to monitor regional drought especially in China that has a mountainous topographty.(2) Based on the interpretation of NDVI-Ts space, NDVI and land surface temperature was combined to construct NVDI-Ts space from which the TVDI (Temperature Vegetation Dryness Index) was obtained with line ratio method and normalized slopes method. When compared with the topsoil moisture measured in situ, TVDI are competent in regional drought monitoring. Illumed by the NDVI-Ts space, we combined the NDVI with day/night land surface temperature difference and apparent thermal inertia to construct NDVI-ΔT and NDVI-ATI spaces from which the DVDI and AVDI were estimated respectively with 8-day composite MODIS 〓 product and 16-day composite MODIS NDVI product.

具体包括以下几方面的内容：(1)VCI和SVI在干旱监测中的作用评价：探讨利用NDVI时间系列数据建立的植被状态指数和标准植被指数评价区域干旱的可行性，研究结果表明：VCI和SVI作为植被相对生长状况指标，对降水的响应随着植被覆盖类型、时间和空间等而表现出不同的敏感性，因此在大区域干旱监测中，特别是我国这样地形复杂多样的国家，VCI和SVI在干旱监测中的作用都是有限的；(2)利用TVDI评价全国干旱等级分布：结合陆地表面温度和植被指数建立NDVI-T〓空间，在NDVI-T〓空间物理意义理解的基础上，分别采用线段比值法和斜率归一化法构建温度植被干旱指数，并利用TVDI研究了我国2000年3～5月份各旬的干旱分布，取得比较满意的结果。

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.

肺活量、肺活量/体重指数，肺活量/胸围指数，肺活量/身高指数，随年龄增大而增大，且有明显的性别差异，指数各年龄组男女均值的变化与其形态发育过程密切相关。

From Japan's stock market performance, PPI peaked down time in February of 1974, but the early fall as a result of PPI in the price index of imported goods under the guidance of a slow down, so until the third quarter of 1974 with the fourth quarter of Inter, GDP deflator is it the real meaning of the fall, while real GDP rose bottom.

从日本股市的表现，生产者价格指数攀升，甚至在1974年2月的时间，但初秋，作为生产者价格指数在进口商品价格指数结果下缓慢的指导下，因此，直到1974年第三季度第四季度国际米兰，GDP平减指数是它的下跌的真正含义，而实际国内生产总值增长的底部。

The Financial Times-Stock Ex**nge 100 Share Index (known as the "Footsie") records the average value of the 100 leading British shares, and is updated every minute during trading.

Filed experiments of 2001 showed that treatments with fungicide either 2 days before or 2 days post inoculation, tebuconazole reduced the disease index of the spikes by 80.32% and 70.64, as well as increased grain yield by 12.95% and 8.74% in comparison to the untreated control. Application of metconazole led to decreases of the disease index by 80.5% and 68.0% and increases of grain yield by 11.41% and 11.45% compared with the untreated plants. In 2002, with the serious occurrence of the head blight, tebuconazole reduced the disease index of the spikes by 76.47% and 78.67% and metconazole reduced the disease index by 82.06% and 81.89% in comparison to the untreated control.
