Using a variety of diversity indexes to study the diversity of grasshopper in different habitat region, the results showed that diversity indexof 5 kinds of habitats has the order: crude redeposit broad-leaf weed-tree forest＞farmland region＞artificial larch tree＞lakefront wetland＞cutting blank.

采用各种多样性指数对不同生境蝗虫多样性进行了研究，结果显示，Shannon-wiener多样性指数的排序情况为天然次生阔叶杂木林＞农田＞人工林＞湖边湿地＞采伐迹地，Pielou均匀度指数变化和H′变化较为一致，相关系数为0.918，达到了显著性水平。

At the lower generation (C5) of the autotetraploid eggplant, plant shape index and the ratio of the well-balanced plants (9.19%) are low. The average shape index for 12 strains of the three different female parents is 0.4779. But its genetic rate is: h^2=96.39%±3.52%. Plant shape index shows strong minus correlation with average fruiting ability, it's relique interrelated coefficient is: r=-0.9989 and correlative heritability is: h=-95.22%.

Since 1997, the trend of deflation has been appeared in our country , the commodity retail price index, the residents consumption price index and the production material trade price index all have been appeared to be negative growth, the increase extent of money supply and the money circulation velocity also have been appeared to decline.

1997年以来，我国出现了通货紧缩的趋势，商品零售价格指数、居民消费价格指数、生产资料批发价格指数均出现了负增长，货币供应量增幅和货币流通速度也出现了下降的趋势。

Based on choosing contrast and definite water conditions, we suggested that relative mean yield of all irrigation treatments, revisionary drought yield index , revisionary water yield index , sensitivity index of stages and revisionary yield index could be used to identify yield, drought resistance, water use efficiency, water sensitivity and water adaptive.

提出在合理选用对照种和明确水分鉴定条件的前提下，采用干旱产量指数修订值鉴定品种的抗旱性，用丰水产量指数修订值鉴定各水分条件下品种的水分高效性，用各水分条件下品种的平均产量相对值鉴定品种的高产性，采用阶段敏感指数鉴定不同生育期的水分敏感性，采用产量系数修订值鉴定品种的适水性。

Based on systematic analysis, nine seismometry parameters that response earthquakes well in North China are selected, which are seismic frequency, seismicity scale, mf-value, b-value, D-value,η-value, seismicity intensity entropy and seismicity time entropy. Using synthetic anomaly index method, we calculated their seismic anomaly index values separately and synthesized these values into a chronogenesis curve. After studying its short-term anomaly characteristics to earthquakes, the criterion index for M≥5.8 earthquakes in North China is obtained. The R-value test indicts that it has good prediction effect.
