To study the effect of papermaking wastewater irrigation on soil hydrological properties in saline reed field, different wastewater irrigation frequencies were employed in the saline reed field of Yellow River Delta. Soil infiltration course and hydrological properties were determined in field and laboratory. After wastewater irrigation, the change of the soil pH value, soil salt content and soil hydrologic-physical properties were observed. The results were showed that: 1 After wastewater irrigation, the mean reduction of soil pH value was 6.0%.

为研究造纸废水灌溉对黄河三角洲内陆盐碱芦苇地土壤水文特征的影响，通过设置芦苇地不同废水灌溉次数下的随机区组试验，采用田间测量土壤入渗过程和实验室内测定水文物理参数相结合的方法，分析造纸废水灌溉前后土壤pH值、含盐率及土壤水文物理参数的变化。

It is suggested that policy should be on the basis of minimum irrigation, soil mulching and straw and manure utilization, and the leading one of its measures should be to use high-salined groundwater as an accompaniment of river water, by the integration of the power-pumped-Yellow-River irrigation system and well-water irrigation system, to lower the watertable and reduce the irrigation cost. Thus the dynamic balance of salts, as well as the prevention and reclamation of salinization, will have been kept through the management of water and soil organic matter.

Applying combined method of quantitative analysis and qualitative analysis, on the basis of on ago research fruit, this paper firstly analyses main factors that affect the safe distance from friendly force to target for tank gun overhead firing systemically. Based on that, this paper builds math model of calculating the safe distance from friendly force to target separately aiming to the difference of tank gun overhead firing in plane and undulate terrain. At last, through applying Mathematica soft, this paper presents the safe distance from friendly force to target for a tank gun overhead firing used APFSDS, HEAT and HESH, combined qualitative analysis.

采用定量分析和定性分析相结合的方法，在以往研究成果的基础上，首先系统地分析并提出了影响坦克炮超越射击时友军至目标安全距离的主要因素；以此为基础，针对平坦地形和起伏地形上坦克炮超越射击的不同情况，分别建立了确定友军至目标安全距离的数学模型；最后通过运用Mathematica软件进行定量计算，并结合定性分析，提出了某型坦克炮使用尾翼稳定脱壳穿甲弹、空心装药破甲弹和杀伤爆破榴弹进行超越射击时友军至目标的安全距离。

A centroid adjustment method is presented which can maintain the horizontal pose robot body when one arm is hung on the overhead ground lines. The balance weight is moved by the servo motor according to the angle of inclination between the inspection robot body and the horizontal plane, which can be checked by the obliquitous sensor, so that the centroid position of inspection robot is concentrated on the arm that is hung on the overhead ground lines. Because the body of inspection robot is kept in horizontal pose, the other arm can accomplish corresponding task for attaching to or detaching from the overhead ground lines.
