随机水文学 meaning in Chinese
stochastic hydrology
Examples
- In process of researching aridity , a important way is to research regional aridity characteristic using the method of stochasic hydrology
应用随机水文学的方法研究一个地区的干旱特征是干旱研究中一条正在探索的途径。 - According to the least twin multiplication to calculating the sensitivity index in several water production functions . thus , the writer obtains the fitted the value of the sensitivity index and the varied rule . at the same time , the writer puts forward a new method named rag a ( real coding based accelerating genetic algorithm ) and combines raga with dpsa to calculating the best irrigation system under the non - sufficient irrigation of well irrigation rice in sanjiang plain
根据《随机水文学》理论中的时间序列分析法，建立了适合三江平原井灌水稻需水量预报的非平稳时序随机模型；通过分析降雨随机特性，选定季节性时序随机模型，建立了适合三江平原井灌水稻降雨预报的月平均降雨模型；根据最小二乘法，计算出几种常用水分生产函数中的敏感指数及敏感系数，进而得到三江平原适宜采用的水分生产函数漠型及模型中敏感指数的变化规律；本文提出遗传动态规划法( raga ? dp ) ，即采用改进的基于实数编码的加速遗传算法( realcodingbasedacceleratinggeneticalgorithm ，简称raga )与动态规划法( dpsa )相结合，推求非充分灌溉条件下三江平原井灌水稻的最优灌溉制度。
