In different replant years, the quantity of bacteria, actinomycete and fungi and the proportion of each in total numbers were different, the quantities of bacteria and fungi increased with replant year increased, while, that of the actinomycete reduced along with replant years increasing.

不同栽培年限蘑菇覆土层土壤中的细菌、放线菌和真菌的数量及其在微生物总数中所占的比例不同：不同栽培年限的土壤样品中，细菌和真菌的数量随着栽培年限而增加，放线菌的数量随着栽培年限的增加而减少。

Although most antibiotics reduced the number of bacteria in pancreas, they affected the balance of intestinal microflora. The QYT herbs could decrease the number of intestinal aerobe, increase the number of bifidobacteria and lactobacillus, and significantly reduce bacterial translocation rate.

绝大多数抗生素虽然能减少胰腺细菌数量，但却影响微生态平衡，而清胰汤能明显减少肠道需氧菌数量，增加双岐杆菌和乳酸杆菌数量，降低细菌的移位率。

According to the change of the enemy\'s quantity and the qualitative theory of the differential equation, we research the spruce aphides and its predator system. At the same time, we discussion the spruce aphid multiplication model when the natural enemy quantity is a certain value and the periodic oscillating model whose the quantity of the natural enemy changes along with the time. Obtains the stability condition of the balance point and the limit-cycle existing condition, the system presents the dissipative structure\'s character. Finally it explains that this theoretical analysis has certain practical significance regarding the preventing and controlling harmful insect.

第五章，松毛虫与其天敌的关系是食饵和捕食者的关系，根据天敌数量的变化，利用微分方程定性理论，研究松毛虫与天敌系统，讨论天敌数量为一定时的松毛虫增殖模型和天敌数量随时间变化的周期振荡模型，得到正平衡点全局稳定性和极限环的存在条件，通过计算机模拟，说明周期振荡的捕食模型能够呈现典型的时间耗散结构特征，对于防治害虫有一定的实际意义。

Through field observations and sampling, by referencing to other documents and information, with correlation analysis and principal component analysis as mathematical tools, we know that: the distribution of the number of birds has close relations with density of zoobenthos and ratio of water area, the correlation coefficient of the distribution and the two factors are 0.916 and 0.745, the density of zoobenthos is the most direct reflection; Vegetation types , the coverage and water level may have relations with the distribution of the kind of birds, normally, middle and large volume birds need high vegetation and high coverage as their habitats, and waterfowl like deep water as their habitats; Human activities have low impact on the the distribution of the number of birds, but the activities have relations with all the other environmental factors.

通过实地的观测、采样，并结合其他文献的资料，以相关分析和主成分分析作为数学工具，得知：鸟类的数量分布和底栖生物密度、水域面积比例有着密切关系，鸟类数量分布与两者的相关系数分别为0.916和0.745，其中，底栖生物密度是鸟类数量分布的最直接反映；植被类型、植被盖度和水位可能与鸟类的种类分布有一定关系，通常体积中、大型的鸟类需要较高的植被高度，来作为自己的栖息场所，水禽需要水位较深的区域作为自己的栖息场所；人为活动对鸟类数量分布的影响不大，但对所有自然环境因子都有一定影响。

Straw returned to field played a positive role in increasing soil insect communities with the largest contribution, primarily the amounts of individuals and dominant species of macro and meso/micro soil animal, especially Neanuridae and Isotomidae animals individual amounts increased by nearly 10 times.(3) Soil nutrien had a positive correlation with soil bacteria, azotobacter, ammonifying bacteria, cellulose decomposing bacteria and denitrifying bacteria. Straw returned to field could stimulate effective microorganisms growth and population quantity in the soil. The increase of microbe community amount is 15%~44% more than that of CK.(4) Soil nutrien had a positive correlation with soil phosphatase, urease and sucrase activities, and a negative correlation with catalase.

研究发现：(1)长期配施秸秆能提高土壤速效氮、磷、钾含量，平均分别提高15%、48%和22%；(2)配施秸秆对土壤昆虫群落呈正向作用且贡献最大，主要增加了大型、中小型农田土壤动物的个体总数和优势类群数量，尤其是疣跳科和等节跳科动物个体数量增加近10倍；(3)土壤养分与土壤细菌、固氮菌、氨化细菌、纤维分解菌和反硝化细菌呈正相关，秸秆还田激发土壤有益微生物的生长和类群数量，使土壤微生物类群数量比对照增加15%~44%；(4)土壤养分与土壤磷酸酶、脲酶、蔗糖酶活性呈正相关，与过氧化氢酶呈负相关，秸秆还田增强土壤蔗糖酶、磷酸酶和脲酶活性，特别是脲酶和蔗糖酶活性平均提高26.5%。

First, in view of a question our supposition newborn babys quantity is , then through to various ages stages survival percentage , the animal quantity which as well as this animals overall quantity analysis moves away establishes this community the dynamic change model , uses in this community near two years various ages stage individual quantity distribution which moves away, with the C language programming computation, extrapolates the current this animals age structure.

首先，针对问题一我们假设新生幼仔的数量为，然后通过对各年龄阶段的存活率、被运走的动物数量以及该动物的总体数量的分析来建立该群落的动态变化模型，利用该群落近两年内被运走的各年龄阶段的个体数量分布，用C语言编程计算，推测出当前该动物的年龄结构。

As PTDT does in threshold traits, PTDT is valid not only for different QTL effect level, but also for maker with multiple alleles and multiple tightly linked markers.(2) Under an appropriate selection ratio s (in this study, s is 0.2, 0.4, 0.6, 0.8, respectively), the power of PTDT can be improved and the genotying individuals can be decreased using selective genotyping design. However, the power of PTDT is related with population size and population structure, an appropriate selection ratio can be defined by simulation based on the existing data.(3) Among the three transforming methods, mixed-family selection is the best, full-sib selection has same power to mixed-family selection in many parameter combinations, and Estimated Breeding Value selection is inferior to them.

数量性状QTL定位的模拟研究结果表明：(1)数量性状经有效转化后，PTDT对数量性状QTL定位保持了阈性状QTL定位的稳健与高效，对不同效应大小的QTL(10％，30％，50％)PTDT都是一个有效的分析方法；(2)在多等位基因标记、多标记方面，PTDT的检验功效与阐性状分析时一样高效；(3)在合适的选择率下(本研究的分别为0.2，0.4，0.6，0.8，1.0)，选择性基因型测定不仅可以减少基因型测定的数量，而且可以提高PTDT的检验功效，但选择性基因型测定的PTDT检验功效很大程度上与群体大小和结构有关，这个可根据具体情况通过模拟找到一个合适的选择率；(4)三种转化方法的转化效力结果表明，家系内混合家系选择的转化效力最高，家系内全同胞选择次之，估计育种值选择的转化效力较差。
