The soil erodibilities are compared and appraised for the majority of the soil types in Ningxia. The method published by D. W. Fryrear et al is adopted to calculate erodible fractions for the soils in Ningxia. The erodibilities of main soil types are compared and analyzed. Spatial distribution of soil erodibilities in the region can be perceived on the Map of Ningxia Soil Erodibility. The map is based on the digitized map of soil types of the all region by means of the geographical information system of Region Manager. Evaluation results show that erodible soils occupy a large portion of the total area of the region.(3) The third task is evaluation of effects of human activities for farming on soil erodibility. Tillage and cultivation can alter soil properties. The paper, based on the discussion on the characteristics of farmland suffering wind erosion in the region, analyzes the contents and intensities of farming disturbing surface soil. Emphasis is paid on the effect of farming on erodibilities of each type of soil.

W Fryrear等人的计算土壤可蚀部分含量的方程，此方程的自变量包括土壤有机质、碳酸钙、沙粒含量、沙粘比，计算了宁夏主要土壤类型表层的可蚀含量，进而比较它们的可蚀性，并以宁夏土壤分布图为底图用地理信息系统建立了宁夏土壤风蚀数据库，完成了宁夏土壤可蚀性图，评价结果显示宁夏地区主要的土壤类型较容易遭受风蚀；（3）农业经营对土壤风蚀的影响及其评价，在分析宁夏农业土壤遭受风蚀特征的基础上，首先讨论了农业活动对土壤理化性质的干扰，评价主要耕作栽培措施对土壤风蚀的影响，选取粗糙度、表面结皮、可蚀颗粒含量、留茬和有效时间为指标，用打分方法作了评价。

CD8~+ cell is the main T lymphocyte subset in spleen, and B lymphocyte mainly is IgG~+ cell, moreover the amount of these B lymphocytes could exceed CD3~+ T lymphocyte subset after 7 days. CD8~+ cell is the main T lymphocyte subset in tonsil of appendix, and B lymphocyte is IgM~+ cell, and the amount could exceed CD3~+ T lymphocytes after 35 days. After 21 days, B lymphocytes in esophago tonsil are the main IgA~+ cells and the amount exceeds CD3~+ lymphocytes. The amount of CD4~+ lymphocytes is more than CD8+ lymphocytes.4. CD3~+、CD4~+ and CD8~+ T lymphocytes in spleen mainly distribute in periarterial lymphoid sheath. However IgM~+、IgG~+ and IgA~+ cells mainly distribute in ellipsoid periarterial lymphoid sheath and germinal center. T lymphocytes in appendix tonsil mainly distribute in middle and inferior part of mucous and the B lymphocytes mainly in middle and mucous between 4~7 days. Whereafter T, B lymphocytes equably distribute in mucous. CD4~+ cells arrange tightly and mainly occupy the central part in aggregates of T lymphocytes in esophago tonsil and CD8~+ lymphocytes mainly distribute in periphery. Meanwhile B lymphocytes encircle the periphery of aggregates of T lymphocytes. The aggregates of B lymphocytes is mainly the germinal center with lots of IgM~+、IgG~+ and IgA~+ cells. Meanwihle T lymphocytes encircle the periphery of aggregates of B lymphocytes.5. There is an intimate relationship between the development of tissue structure of peripheral immune organs and lymphcytopoiesis. The maturation of tissue structure is stimulated by the immigration of lymphocytes and the mature tissue structure provides place where lymphocytes grow mature and functionate.

脾脏在21日龄时达到稳定，食管扁桃体和盲肠扁桃体均在35日龄时达到稳定；脾脏中T淋巴细胞亚群以CD8~+细胞为主，B淋巴细胞则以IgG~+细胞为主，并在7日龄后数量超过CD3~+T淋巴细胞；盲肠扁桃体中T淋巴细胞亚群以CD8~+细胞为主，B淋巴细胞以IgM~+细胞为主，并在35日龄后数量超过CD3~+T淋巴细胞；21日龄后，食管扁桃体中B淋巴细胞以IgA~+细胞为主，数量超过CD3~+细胞，CD4~+细胞的数量多于CD8~+细胞。4、在T、B淋巴细胞组织定位方面，脾脏中CD3~+、CD4~+和CD8~+T淋巴细胞主要分布在动脉周围淋巴鞘中，而IgM~+、IgG~+和IgA~+细胞主要分布在椭球周围淋巴鞘和生发中心中；4～7日龄时，盲肠扁桃体中T淋巴细胞主要分布在粘膜固有层的中下部区域，而B淋巴细胞则主要分布在中上部区域，随后各日龄T、B淋巴细胞均匀地分布在粘膜固有层中；在食管扁桃体的T淋巴细胞聚集物中，CD4~+细胞紧密排列，主要占据中央部位，CD8~+细胞主要散布在外周，同时B淋巴细胞又环绕在整个T淋巴细胞聚集物的外周；B淋巴细胞聚集物主要为生发中心，其中存在大量IgM~+、IgG~+和IgA~+细胞，同时T淋巴细胞又环绕在整个B淋巴细胞聚集物的外周。5、外周免疫器官的组织结构发育和淋巴细胞发生之间存在密切的关系，淋巴细胞迁入淋巴器官刺激组织结构的发育成熟，同时成熟的组织结构又为淋巴细胞发育成熟并行使功能活动提供场所。

This thesis analyzes theoretical base about the back-to-life curriculum in kindergarten from the angle of life, life and children, life and curriculum, which put forward the point that life is definitely to occupy, enjoy, assimilate and create the material culture, spiritual culture and institutional culture of human beings, and life is an motile activity which exists, develops with a person"s life and which can realize a person"s life values.
