The main researching contents included as following:relationships betweenspecies diversity,community richness,vegetation succession,soil volume weight,solu-ble Na+concentration and five soil chemical elements(N、P、K、Ca、Mg)concentrationwith grazing intensities in the grassland.Relationships between concentrations,re-serve pools of plant nutrient materials,including five macroelements(N、P、K、Ca、Mg),crude protein,crude fibre,crude fat and total nonstructural carbohydrate,and their allocations in defferent plant parts with grazing intensities in thegrassland.Effects of grazing on Leymus chinensis population were also examined andthat more attentions were paid on the responses of many biological characteristics ofabove-and below-ground plant modules to different grazing intensities.Furthermore,in the respects of plant production,survival rate,tillering ability,total nonstructuralcarbohydrates content and others,the effects of one years different defoliationpatterns on the vitality of Leymus chinensis population were detected.

主要研究内容有：放牧对羊草草地植被和土壤的影响，致力于物种多样性、群落丰富度、植被演替和植物生产量、以及土壤容重、土壤水溶性Na+含量和五种土壤大量营养元素(N、P、K、Ca、Mg)的含量等土壤理化性状与放牧强度关系的分析，分析了不同放牧强度与羊草草地草群和羊草种群地上和地下各植物部分中多种营养物质的浓度、贮量及其分配的关系；放牧对羊草种群的影响，注重了羊草种群的地上与地下各植物器官对不同放牧强度的反应和适应性变化，最后，从植物生产量、存活率、分蘖能力以及总非结构性碳水化合物含量等方面，探讨了不同人为去叶方式组合对羊草种群当年和次年生活力的效应。

The seasonal pattern of parasitism of the white-backed planthopper, Sogatella furcifera, was investigated in a subtropical double cropping of rice ecosystem in hilly region Jinghua-Quzhou Basin, Zhejiang, China.

在亚热带浙江金衢盆地的丘陵双季水稻田的早、晚稻期间研究了白背飞虱的被寄生和被捕食作用下的存活率。早、晚稻白背飞虱卵被缨小蜂寄生率分别为 1 1 %和 1 6 %，被捕食及未知因子死亡率分别为 2 3%和 1 6 %。

For example, victims of the Death Cap, one of the deadliest mushrooms, may not feel anything _(3)_ during the first 12 hours. But beginning in the 13th hour, the victim may start to have violent stomach pains and gas. Vomiting and diarrhea follow shortly. And finally, their liver and kidneys fail and they have only a 50 percent chance of survival. The survivors are spared but have to _(4)_ permanent liver and kidney damage for the rest of their days.

例如，误食一种名为『毒鹅膏』的致命毒菇，前十二个小时可能不会有任何异状，但第十三个小时开始，中毒者会开始产生剧烈腹痛和胀气，接着上吐下泻，到最后会导致肾脏和肝脏衰竭，中毒者只有百分之五十的存活率，但幸存者必须终身饱受肾脏和肝脏损伤。

That you will be able to raise the survival rate.

这就能提高你的存活率。

Results:The 1~5 years survival rate was 100%.
