水污染

In order to evaluate the risk of groundwater contamination resulting from pesticide leaching, a new fugacity model was developed on the basis of former researchers'work. In this model soil was divided into two compartments: unsaturated consisted of three subcompartments: air, water, and soil solid, and saturated phase consisted of two subcompartments: water and soil solid.

在上述实验研究的基础上，结合农药污染地下水的研究在环境中的重要性，提出了一种包含地下水相在内的土壤多介质环境逸度模型，把土壤分为不饱和层相（由空气、水、土壤固体三个亚环境相组成）和地下蓄水层相，用来评价农药对地下水污染的情况。

In the end,the countermeasures were given to the groundwater pollution issues by coal gangue.

最后对煤矸石山淋溶液对地下水污染问题提出了治理措施。

Optimal algorithm of combined nonlinear Hopfield network appears powerful validity in solving nonlinear planning, which includes nonlinear objective function, linear constrains and high-demension of decision-making variants, for its ability of nonlinear parallel computation. It is prominent among optimal algorithms because of its function of simply implement with electrocircuit hardware. Genetic algorithm is expressly suitable for optimal calculation regarding the planning of massive, highly nonlinear, inconsecutively differentiable and multiobjective function as well as objective function without analytical expression. However, it inclines to prematurity, as well as its limitation in ability of partial optimal search. Introducing the optimal algorithm of niche genetic simulated annealing to standard Genetic algorithm, can therefore improve the full-scale or partial search ability of Genetic algorithm effectively. It has a far-flung perspective in the field of systemic planning of water pollution control.

组合式非线性Hopfield网络优化算法所具有的非线性大规模并行计算能力在求解具有非线性目标函数、线性约束条件及高维决策变量的非线性规划问题方面显示出了强大的生命力，它易于电路硬件实现的功能更是在优化算法中独树一帜；遗传算法采用概率搜索技术，不受目标函数与约束条件的限制，特别适合大规模、高度非线性的不连续可微的多峰目标函数及无解析表达式的目标函数的规划问题的优化计算，但其存在容易早熟、局部寻优能力较差等缺点，本文在标准遗传算法中引入小生境技术及模拟退火算法有效地改善遗传算法的全局和局部搜索性能，提高了全局最优解的寻优质量，小生境遗传退火模拟优化算法在水污染控制系统规划中的应用前景极为广阔。
