Based on these researches,a full theoretical method is established, which is an applicable to determine all possible STPR mechanisms of anyone usable topological limb.Finally,this family of STPR mechanisms is determined one by one.Each mechanism in the family is depicted by means of the type of its topological limb,the actuated layout,and the structure parameter.

Firstly, velocity expression of translational parallel manipulator was presented based on the screw theory. Secondly, the actuated screw, the actively unactuated screws and idle screws of each limb were determined according to the reciprocal screw theory. Then, all basic kinematic chains were enumerated by means of the number of limb connectivity and the limbs containing closed-loops were obtained by replacing the passive prismatic joints in the basic kinematic chains with planar closed-loop structures.

位移监测信息分析及综合法从变形的多种预测方法的运用及结果比较，到用于评价边坡整体加固效果和不利因素对边坡损害程度的综合研究，旨在帮助工程师进行动态设计和信息化施工。

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。

Three strains of bacteria were isolated from haemolymph, hepatopancreas, ascites and muscle of the diseased Eriocheir sinensis caused by aeromonas. All of the three isolates were Gram-negative rods, motile by means of single polar flagella, and were facultatively anaerobic; Glucoce was catabolized with production of acid and gas; Oxidase was positive.

利用硫酸铵盐析、Sephadex G-100凝胶层析和DEAE-Cellulose离子交换柱层析等方法，从其胞外产物中分离纯化出了2种胞外蛋白酶，用SDS-PAGE电泳测得两种蛋白酶的分子量分别为39.6kD和20kD.39.6kD蛋白酶活性在50℃～60℃范围内热稳定性最好，最适pH为9，而20kD蛋白酶的最适温度为50℃，最适pH为8。
