The proper hydrology model on the gird cell plays an vital role in the Distributed Hydrology Model, In this paper, It is divided two parts in vertical section, they are up-ground and under-ground relating to rainfall, air temperature, evaporation and ooze hydrological model, At the same time, I integrate all indispensable data and found two databases which are geographical information database and hydrological information database, write program using computer language—VB to simulate process of isochrones of the watershed.

创建分布式水文模型的关建是建立一个合适的基于栅格单元的水文模型，本文将栅格单元在垂直方向上分为二层，即地表层和地下层，涉及到降雨、温度、植被截留、蒸散发、下渗等水文计算模型；并综合各类相关数据，建立了地信数据库和水文数据库，通过VB编程进行等时流线模拟计算。

The time from May to September is the active time of hydrological process, which occupies 85% of annual runoff; the spring flood and summer flood are founded in hydrological process, the peak of summer flood is larger than spring flood.

结果表明5-9月为研究流域的水文过程活跃期，该时段内的径流量占全年总径流量的85%；径流过程中存在春汛和夏汛，夏汛洪峰值明显高于春汛。

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。

To predict the geometric operational range of an acoustic homing torpedo under different hydrological condition, this paper presents a method to determine geometric operational range by using sound ray density.

为预报声自导鱼雷在不同水文条件下的几何作用距离，提出了运用声线密度判定几何作用距离的方法。
