Kinetics of methanol dehydration to dimethyl ether on modified kaolin catalyst was studied in an integral reactor under normal pressure. It is deduced that the surface reaction of methanol molecule adsorbed on the active site of catalyst with methanol molecule in gas phase is the rate determining step. The hyperbolic type kinetic equation r=ksbMpM2/(1+bMpM+bpE) is obtained according to the theory of langmuir even adsorption and using the R-E mechanism.

采用积分反应器，考察了常压下在改性高岭土催化剂上甲醇脱水生成二甲醚的反应动力学，根据Langmuir均匀吸附理论，采用R-E机理，推断吸附的甲醇分子与气相主体中的甲醇分子发生的表面反应为速率控制步骤，得到双曲线型动力学方程为： r= ksbMpM2 /(1+bMpM+bpE)（r为反应速率， ks为反应速率常数， bM为甲醇的吸附平衡常数， b为二甲醚和水的吸附平衡常数之和， pM、 pE分别为甲醇、二甲醚的分压）。

According to the experiment results of degradation in field, degradation mechanism of the biodegradable mulch film can include four stages: the first, the material surface appeared deficiency while the surface area and interstice increased of material in the action of natural environment and microorganism; the second, along with the surface area and interstice of material increased and the gap strengthened, the chemical chain of the high polymer's principal chain broke as a result of the hydrolysis or the enzymatic effect in the action of hydration, causing the molecular weight and mechanics function descended; the third, the molecular of high polymer split the low polymer after its physical mechanical function descended, the material decomposed the fragments, the mass defect intensified; the fourth, the low polymer of fragments form in the natural environment, the microorganism, the biological enzyme became the smaller fragments, thus absorbed by the phagocytes, or further turn into CO2 and H2O due to hydrolysis.

根据田间降解试验结果推测，生物全降解地膜的降解机理可能包括四个阶段：第一，在自然环境、微生物作用下，材料表面出现缺陷，同时表面积增大、空隙增多；第二，随着材料表面积的增大、空隙的增多，吸水性增强，在自水合作用下，高聚物主链由于水解或酶解而使化学链断裂，导致分子量和力学性能下降；第三，在其物理机械性能下降后，高聚物分子链断裂为低聚物分子，材料裂解为碎片状，质量损失加剧；第四，碎片状低聚物在自然环境、微生物、生物酶作用下进一步水解变成尺寸更小的碎片，从而被吞噬细胞吸收，或进一步水解，生成CO2和H2O。

Landmarks such as the virgin-white Dives in Misericordia Church in Rome and the Marunouchi Building in Tokyo were among the first to be coated with the semiconductor, which breaks down organic molecules—including those in grime and pollution—when exposed to light and water and then releases them into the air.

象罗马洁白无暇的仁慈天主教堂和东京的丸之内大厦等标志性建筑，将属于首批运用这种半导体涂料的建筑物。当与 hat中文是什么光和水接触的时候，这种半导体涂料能够降解有机分子－包括尘垢和污染物中的有机分子，然后将它们释放到空气中去。

In salt solution, because of the role of ionic charge, so that intramolecular hydrophobic chain to enter into force enhancement, molecular chain contraction, so value continued to drop.

在盐溶液中，由于离子电荷的作用，使疏水链节分子内缔合力增强，分子链收缩，因而值也持续下降。

The recent progress in preparation and recognition of molecularly imprinted polymers in aqueous phase are overviewed and discussed.

Oil is a nonpolar molecule, while water is a polar molecule.

油属於非极性分子，而水属於极性分子。

During incubations, significant uptake fluxes of NO(superscript - subscript 3) and SiO(superscript 2- subscript 3) were commonly shown at the sediment-water interface, and largely controlled by their concentrations in the overlying water. The molecule diffusive fluxes, calculated from the concentration gradients between overlying water and surface pore water, seemed not so important in the exchange fluxes.

沉积物－水界面交换过程在春季表现为对NO(上标-下标 3)和SiO(上标 2-下标 3)的吸收，吸收的量在很大程度上取决于上覆水中这两种营养盐的浓度；由上覆水和表层间隙水浓度梯度所决定的分子扩散通量对实际交换通量的控制有限。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
