The progress levels of symptoms after pathogen infection showed that interaction of gray leaf spot pathogen and host has differentiation or polymorphism. The progress levels of symptoms is different.The aggressively has polymorphism. The pathogenicity of different isolates in same cultivar has polymorphism, or the host reaction type of same isolate in different cultivars has polymorphism.The host reaction type has differentiation. There are seven types of host reaction in cultivar and inbred after infected by GLS pathogen:Rectangular lesion without chlorotic halo, Rectangular lesion with chlorotic halo,Irregular lesion without chlorotic halo,Irregular lesion with chlorotic halo, Spot lesion with chlorotic halo,Rectangular and irregular lesionand Rectangular and spot lesion. The host reaction type is coalesced lesion when disease severely. Frequency of each reaction types is different.

通过对玉米灰斑病菌侵染后的显症过程的系统观察，可在组织水平上说明该病菌与寄主互作反应存在分化或多样性：玉米灰斑病菌不同菌株侵染后显症过程表现出明显的差异；玉米灰斑病菌在侵袭力上存在多样性，菌株间对同一种品种的致病性表现多样化，或者同一菌株对不同品种侵染引起的寄主反应表现为多样性；病斑反应型的分化，玉米灰斑病菌侵染玉米品种或自交系后，主要有7种病斑反应类型，即RH型、RN型、IRH型(不规则形具褪绿晕圈病斑)、IRN型(不规则形无褪绿晕圈病斑)、SH型、RI型(长矩形与不规则形混合病斑)和RS型(长矩形与斑点形混合病斑)，若发病严重，病斑连成片，而且这些反应类型出现的频率也不同。

To validate the above conclusion, a series of mixture tests were performed and different samples were made by mixing each of three kinds of nature silt and the nature clay with different mixture ratio. The liquid-plastic limits of all the samples, in which the clay particles content were between the nature silt and the nature clay, were attained using the combined test method. The results showed that the lowest clay particles content of the silt, when it was suitable with the combined test method, is 12% to 15% with little differences. If the point of 3～4mm depth of penetration of fall cone exist, and the loglog relationship between the depth of penetration of fall cone and the water content of all the points were clearly linear, it could be concluded that the clay particles content of the sample is over the lowest value when the combined test was suitable.

3其后为了进一步验证所得结论，针对三种粉土，分别与一种黏粒含量较大的天然黏土进行多种组合的配比试验，配比后的土样其黏粒含量均介于原粉土与原黏土之间，并对各种配比后土样进行联合测定法确定液、塑限的试验研究，得出各种土对联合测定法适用的最低黏粒含量限值因粒径组成不同、矿物组成不同等因素，存在微小差异，在12%到15%之间；当圆锥下沉深度在3～4mm之间的试验点存在，且与其他试验点之间能形成良好的双对数直线关系，即认为土中黏粒含量超过该土对联合测定法适用的最低限值，联合测定法适用。

The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.

结果表明：各物种的热值动态变化规律并不是统一的，这种变化可能与植物各器官热值的变化及生殖期出现的时间有关；各植物器官的热值普遍表现出穗的热值大于茎和叶；水生植物的热值明显小于中生性和湿中生性植物；种内热值变化随物候期变化有一定的规律，大约会出现2次低值、2次高值；种间热值差异是由于植物本身性质决定的，在相同生境和气候条件下，植物体中含能物质越多，就越易积聚热值，从而更适宜生长在此环境。

Compared with the original powder, the content of Si in the three troches increased by 8.09, 14.68, 12.64 times respectively. Accordingly, they were added with a little amount of silica gel. The content of trace element such as Ca, Fe, Zn in sample 4 have optimized clearly.

结果表明，当载荷较小时，2种理论计算出的弹性大挠度悬臂梁的变形曲线差别很小；而当载荷较大时，2种理论计算出的弹性大挠度悬臂梁的变形曲线存在比较明显的差异。

The results showed that highly significant differences were observed between the two nitrogen treatments and also among family lines in the 4 nutrient contents. Applicating nitrogen may increase the contents of CP and CF in stalk, but decrease the contents of ADF and NDF. The variance segregation of stalk nutrients of F2∶4 lines were in normal distributions and with over parent segregation in some degree. The sensitivity to nitrogen fertilization varied with maize genotypes.

结果表明，两种氮肥处理之间以及不同家系之间各营养成分含量差异均达极显著水平；增施氮肥有利于提高秸秆的粗蛋白和粗脂肪的含量，降低酸性洗涤纤维和中性洗涤纤维的含量；两种氮水平条件下，不同家系之间秸秆各主要营养成分含量的变异性分离均符合正态分布，并存在不同程度的双向超亲分离；不同基因型的玉米对氮素的敏感性各异。

The differences of the micro structure and properities of the bulk sinters, between the fabrication methed of powder metallurgy and reactive synthesis for silver tin oxide composite, are studied in prensent thesis. With the increase of the tin oxide content in silver matix, the electric conductivity of the composite tended to decreace. While in the same tin oxide content, the electric conductivty of the composite fabricated by reactive synthesisis better than that by powder metallurgy. One of the reasons is that the regular net structure existing in former composite.

研究了两种方法即粉末冶金法和反应合成法制备的银氧化锡复合材料烧结坯在组织上的区别和性能上的差异，两种方法制备的银氧化锡复合材料，随着氧化锡含量的升高，材料导电性均呈下降趋势，而相同成分的材料，反应合成法制备的银氧化锡复合材料的烧结坯的导电性要优于粉末冶金法，有规则的网络状组织结构是反应合成法制备的烧结坯导电性好的原因之一。

Asian citrus psyllids and in the Citrus Aphis citricola both the phloem feeding insects, but insect feeding behavior of two significant differences, in addition to two kinds of insects share a common EPG wave (A wave, B wave, C wave, E1 wave, E2 wave, G wave), the wave of Aphis citricola appeared in the path of many pd wave, pd wave is aphids in plant cells in the epidermis during exploratory puncture the cell membrane caused by feeding, which kind of contact information on the intracellular selection in the aphid host plant play an important role in the process.

求中文翻英文翻译，很急，谢谢亚洲柑桔木虱和绣线菊蚜在沙田柚上都为韧皮部取食性昆虫，然而，两种昆虫的取食行为有明显差异，除了两种昆虫拥有共同的EPG波形（A波、B波、C波、E1波、E2波、G波）外，绣线菊蚜在路径波中出现很多pd波，pd 波是蚜虫在植物表皮层细胞的试探性取食时刺破细胞膜而产生的，这种对胞内信息的接触在蚜虫选择宿主植物的过程中起了重要作用。
