During the period of the mineralizing, the surroundings of studying are is continental facies. The aggraded materials who have experienced long time efflorescence and leaching have corrosion and eluviated the alkali metals, alkaline earth, silicon, iron and so on. The schwer l Al2O3 is keeped down. So this condition made the enrichment of the aluminum and the bauxite is formed.

铝土矿成矿时期，研究区为陆相环境，已沉积物质在炎热潮湿的气候条件下经历了长期的风化淋滤作用，将碱金属、碱土金属、硅、铁等溶蚀淋滤掉，难溶的Al2O3残留下来，造成铝的富集，形成了铝土矿。

In this work, an attempt was made to use ultrafiltration to replace conventional resin decoloring unit operation.

在实验中使用了切割分子量为4960.5u的超滤膜，实验结果表明超滤是取代树脂脱色的有效手段，可以充分纯化土霉素结晶液并改善结晶，脱色过程收率由树脂法的95.3%提高到98.6%。

On the basis of the test results and site investigation, the chemical clogging mechanism was analyzed. Ferric mineral in the stratum is deoxidized.

针对长江堤防典型的地层砂样，采用砂砾石和聚氨酯作为反滤料，利用葡萄糖溶液模拟地层中的还原条件，开展了反滤试验；并结合对实际减压井运行的观察，分析研究了化学淤堵的机理。

Composite membrane was applied in the desalination-purification for dye KB-R, and the rejection for KN-R was kept at nearly 100% and the flux waved about 45L/m h. The dye KN-R was almost desalinized through 8 times cycle.The separation properties of three hollow fiber composite membranes for nucleotide containing phosphate were tested at 0.6MPa, room temperature.

在室温、0.6MPa下，考察了CMa，CMb和CMc三种复合纳滤膜对含有磷酸盐杂质的核苷酸的分离性能，膜CMc对核苷酸的截留率最高(达97.9％)，同时膜的通量也较大(为27.5L／m~2h)，因此选用膜CMc作为核苷酸分离用复合纳滤膜(来源：A586d0dBC论文网www.abclunwen.com)。

Through the above structure, it can extend the life of the filter element pipe, improving dewaters effect, realizing time control of the oil water partition line with automatic exhaust of water.
