Based on the continuously irrigating model test of brackish water(4.7g·L-1)on the shallow thick-bedded clay parting heavy loamy soil with treatments of different amendments,such as zeolite,phospho-gypsm and so on,the effects of long term brackish water irrigation on the physical and chemical characters of soil and the effects of amendments on the soil of long term brackish water irrigation were all discussed.

结果表明，长期灌溉微咸水有恶化土壤化学性状、物理性状的趋势，土壤表层聚盐、氯钠离子比例提高、土壤初始入渗率逐年降低，短期灌溉还能破坏土壤水稳性团聚体，但施用沸石、磷石膏等适宜土壤改良剂能够起到缓解的效果。

Natural fermentation of corn in the process of lactic acid bacteria as the most important advantage of strain, the article on lactic acid fermentation process in detail the analytical results show that: from chemical constituents, the ferment of lower ash, soluble sugar, fat content, protein, starch proportion cases raising; from the structure of starch, amylose fermentation in the increase, in molecular weight amylopectin rice amylopectin close to the molecular weight of the development.

在玉米米粉制作的过程中，发酵的方法能改良玉米的性质使其具有可加工性、改善玉米的不良风味。玉米自然发酵的过程中，乳酸菌为最主要的优势作用菌种。对乳酸菌发酵的过程进行详细的解析表明：从化学成分上来讲，发酵作用降低了灰分、可溶性糖、脂肪的含量，使蛋白质、淀粉所占比例提高；从淀粉结构来讲，发酵使直链淀粉含量增加，支链淀粉分子量朝着接近大米支链淀粉分子量的范围发展。

The main results are:(1) The cumulate cause-effects model was demonstrated at both macro and micro level data. The problem of data fitting of hypertension prevalence data was solved well enough with the cumulate cause-effects model. The parameters of the model were meaningful for the practice.(2) Taking the hypertension developing speed as an indicator of health equality of hypertension between urban and rural residents in China and discovered the macro level determinants of it.(3) The causal network was testified by the structure equation model.(4) It is found that the major determinants of hypertension prevalence in China is population ageing, overweight, lifestyle changing due to high economic developing speed and the lagging behind of health education.

主要的研究成果有：(1)首次观测到我国高血压的患病率曲线符合累积风险效应模型，解决了高血压患病率资料数据拟合中长期存在的方法学问题，并对模型中参数的实际流行病学意义给出了合理的解释，能够对疾病的发病率进行间接的估计；(2)提出了用高血压的发展速度作为衡量我国城乡高血压造成的健康不平等的重要指标，解决了我国高血压患病率评价中长期存在的一些错误性认识，揭示了我国高血压城乡发展不平衡的宏观决定因素；(3)利用结构方程模型对构建的网络模型进行拟合分析，证明了模型的有效性；(4)揭示了目前影响我国高血压发展趋势的决定因素，主要包括人口老龄化趋势加剧、超重人口比例增加、经济的快速发展带来生活方式的转变和健康教育的相对滞后等几个方面。

Microstructure and property of electrospun regenerated silk fibroin /gelatin nanofibers;2. Regenerated silk fibroin membrane was prepared by using waste silk at room temperature.

采用桑蚕废丝制作再生丝素室温干燥膜，并以不同质量比例与水溶性胶原蛋白混合，溶解于质量分数为98%的甲酸中制得不同质量分数的纺丝液，选择一定的工艺参数进行静电纺丝。

In the light of geological characteristics of Dongfang 1-1 Gas Field, mass indoor experiments are conducted and studied. Sand grain level are analyzed, the sand control parameters and screen pipe and blind pipe combination proportion is optimized. On this basis, the most suitable horizontal screen pipe sand control method for this gas field is found. Through the medium of DONGFANG 1—1 gas field field conduct proven, the sand control technology are completely run up to DONGFANG 1-1 gas field completion require.

针对东方1—1气田的具体地质特征，通过大量的室内实验研究，对地层砂粒度进行了分析和分选性研究，对防砂参数和筛管与盲管的组合比例进行了优化，从而找出最适合该气田的水平井筛管防砂完井方法，通过东方1—1气田的现场实施证明，该防砂技术完全达到了东方1-1气田完井的要求。

Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.

间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大，而玉米最小，可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2）间套大豆根际pH值的下降，导致磷肥施入土壤后形成〓-P的比例显著提高，转化成〓-P等难溶性磷减少，说明间套的大豆能减缓肥料磷在土壤中的转化和固定，减少磷素向无效化方向转化。3）复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区，而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异，说明根际磷才是真正有效磷，根际施磷是解决磷素竞争的有效途径。4）。
