在模拟氧化及酸性土壤条件下，用制备的低聚合羟基铁-蒙脱石复合体进行了砷酸根、铬酸根离子的竞争吸附实验，研究了砷酸根离子和铬酸根离子不同用量及不同添加顺序对竞争吸附的影响，并与蒙脱石和含水氧化铁进行了对比。

The results of experiments and analysis shown that the clay mineral is mainly gerundive, montmorillonoid is little, but a great quantity of sodium-ion in gerundive soil and larger pH make the soil as well as montmorillonoid which is intense dispensability, These are two keys for the soil to disperse.

试验和分析结果表明，土样中的粘土矿物主要以伊利石为主，蒙脱石含量较少；伊利土中含有大量的钠离子，使得伊利土象钠蒙脱土一样具有强分散性；pH值较高，使得土壤颗粒之间的净势能表现为斥力，这也促使土样土样产生分散性。

In the first part, this paper makes use of the uniformity experiment method to choose the best remarkable factor and the optimized technics to affect montmorillonite modification, and analyses the structure of organized montmorillonite, intercalate mechanism and array mode of modifying agent in interlayer.

Measured the levels of serum unconjugated bilirubin before and after the treatˉments in each group.

在相同光疗的基础上实验组加用蒙脱石散剂，观察两组治疗后血清胆红素水平的变化程度，同时观察便性状改变情况，评价蒙脱石散剂联合光疗的疗效。

The studies on crystallochemical structure of montmorilloni te indicates that the montmorillonite has a higer ordering degree and a larger l ayer charge.

蒙脱石的晶体化学结构研究表明，蒙脱石有较高的有序度和较大的层电荷，因此，上天梯膨润土适合于制备高效活性白土。

EPR study of the thermal products of these montmorillonites shows that g = 2. 14 signal relates with hydrated copper ions existing in the interlayer of montmorillonites and g = 2. 07 signal relates with Cu~(2+) occupying the ditrigonal cavities of Si-O sheet. And, the supper fine line of g ca. 2. 2 - 2. 7 suggests Cu~(2+) migrating into octahedral vaeancies.

同时，该蒙脱石热处理产物的EPR研究表明、g=2.14信号与蒙脱石层间的水合铜离子相关， g=2.07信号和g为约2.7-2.2超精细结构线分别与进入了粘土矿物Si-O四面体片复三方形孔洞和铝氧八面体空位中的Cu相关。

同时，该蒙脱石热处理产物的EPR研究表明、g=2.14信号与蒙脱石层间的水合铜离子相关， g=2.07信号和g为约2.7-2.2超精细结构线分别与进入了粘土矿物Si-O四面体片复三方形孔洞和铝氧八面体空位中的Cu相关。

The results indicate that interlamellar structure of montmorillonites, amount of surface acidity and its decoloring performance show significant dependence on methods and conditions used.

结果表明，制备方法、条件等对蒙脱石层间结构、表面酸量及表面吸附性等均有较大的影响，且交联蒙脱石在400℃以下热稳定性较好。

Methods The adsorbing effect of montmorillonite was observed in vitro and the effect of decreasing serum concentration of uric acid was studied on acute hyperuricemia model mice. The concentration of uric acid was measured by the reduction method of phosphotungstic acid.

用离体实验研究蒙脱石对尿酸的吸附作用；用小鼠高尿酸血症模型研究蒙脱石降低血尿酸的作用；用磷钨酸还原法测定尿酸含量。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
