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。

It was found that because of the difference in component distribution and structure, the tendency that pores furcate and bend was smaller in amorphous precursor than in crystalline precursor, and for the amorphous precursor, the velocity of Al leaching-out and the expanding of specific surface area of catalyst were more sensitive to activation process parameters.

结果发现，由于两者在组元的分布及结构上的差异，非晶态前置体合金在活化过程中形成的微孔发生弯折、分叉的倾向要小于晶态前置体合金，同时前者在活化过程中的抽Al速率、以及所得到的催化剂的比表面积等对活化工艺更为敏感。

A new recovery technology of solid waste was made which is from furfuryl alcohol production by furfural hydrogenization. When the solid waste is placed in a vacuum drying box, and is under lower negative pressure and at 130℃, the organic materials in solid waste can be distilled and then returned to the refining workshop to produce qualified furfuraldehyde and furfuryl alcohol. The remainder is mixed with soda ash and roasted in a reverberating furnace. The sodium chromate can be obtained by leaching. Rough cupric oxide is dissolved in nitric acid and cupric nitrate is obtained. A new catalyst was prepared by the above sodium chromate and cupric nitrate and used in furfuryl alcohol production.

将糠醛液相加氢生产糠醇产生的废渣置于真空干燥箱中，在较低的负压状态下保持130℃的温度，蒸馏回收废渣中的有机物，返回糠醇精制车间获得合格的糠醇与糠醛产品；剩余的固体废弃物与纯碱混合，在反射炉中焙烧，浸取获得铬酸钠水溶液；最后剩下的粗氧化铜溶于硝酸得到硝酸铜溶液；将铬酸钠溶液、硝酸铜溶液按一定比例混合，加入氨水搅拌，分离出的沉淀经传统方法焙烧活化、造粒制得新催化剂，回用于糠醛液相加氢生产糠醇。

The effect of ferrous iron on the leaching rate of gallium and phosphorus was not significant.

镓和二价铁离子的沉淀率随磷酸根离子浓度的增加而增加，当磷酸根离子与金属离子摩尔比大于1：1后，磷酸根离子浓度对沉淀率的影响不再变化；温度对镓离子沉淀过程的影响较小，对二价铁离子的沉淀过程影响较显著。

The results showed that Weipa ore is gibbsite and its leaching efficiency is high when digested at higher than 200 ℃,so applicable to sweetening ore in digestion process,under conditions that the sweetening process is controlled in the range of 195～200 ℃ for 15～20 min and the dosage of Weipa .

对澳大利亚韦帕矿的溶出性能及以韦帕矿为后加矿的增溶溶出技术进行了实验研究。考察了增溶温度，增溶时间，后加矿加入量对溶出效果的影响，同时对后加矿增溶溶出的矿浆性能进行了对比性研究。结果表明：韦帕矿为三水铝石矿，在200℃以上溶出时，浸出率较高，适宜作为增溶溶出过程的后加矿。以韦帕矿为后加矿，其适宜的增溶溶出条件为：增溶温度195~200℃，增溶时间15~20 min，后加矿的质量分数为15%~20%。后加矿增溶溶出矿浆具有优良的沉降压缩性能
