The results obtained by electron microscopic observation show that the supercoiled pUC18 DNA adopts a doughnut-like solenoidal structure with outside diameter about 43.8 nm and inside diameter about 2.0 nm in ammonium acetate-H2O medium.

观察结果显示：在疏水性的甲酰胺-水展开系统中，DNA采取通常的互缠式结构；在含有1.5 mmol/L醋酸铵的水介质中制备的超螺旋DNA标本，DNA采取线圈型结构，测得pUC18 DNA分子这种结构的外直径约为43.8 nm，内直径约为2 nm。

It has also been found that the density of water in droplets was significantly larger than that of free water, and was varied with the solvents, while the configuration of AOT molecule kept unvaried.

发现在微乳液滴中的水的密度明显大于自由水的密度，并随溶剂变化，而AOT分子的构型不变。

Water passageway albumen forms the velar channel of solute of alternative carriage water, young member and gas, grow in the plant main effect has in development process.

水通道蛋白形成选择性运输水、小分子溶质及气体的膜通道，在植物生长发育过程中起重要的功能。

After the basis set superposition error correction and the zero point vibration energy correction, the interaction energies for three types of NMA-acetic acid complexes and one type of NMA-water complex were -44.3,-35.5,-32.4 and -16.0 kJ·mol-1 respectively, which showed that NMA had a great affinity for acetic acid than water.

NMA与水\醋酸之间都有氢键形成，经计算得到NMA-醋酸复合物的稳定化能在-32.4~-44.3kJ/mol之间，且平面构型的NMA-醋酸复合物稳定能较高，而NMA与单分子水的稳定化能仅为-16.0kJ/mol。

The results show that the dehydration efficiency improves with the increase of the amount of butanol during the continuous distillation dehydration process;the first four coordinated water molecules in bischofite can be more easily taken away than the last two coordinated water molecules,especially the last one;the ultrasonic pretreatment of the bischofite bu...

研究结果表明：在连续蒸馏法脱水过程中，水氯镁石的脱水率随着丁醇用量的增加而提高；水氯镁石最初4个结晶水分子较容易脱除，后2个结晶水特别是最后1个结晶水难以脱除。

Cation group has the capability of charge neutrality and this would make oily wastewater demulsify and remove oil easily. Hydrophobic group would improve hydrophobic-oleophilic nature of the oil granule. Simultaneously, wetting reversed agent would change wetting performance of oil granule, enhance conglutination capability between air bubble and oil granule. And Frother would form bigger foam layer on the water, so it could prevnt granule with air bubble from rolling downward.Using the hydrophobic polymeric flocculant as one of ingredients for flotation agent formula, the flotation agent has good treatment effect.

浮选剂配方中的疏水性高分子絮凝剂分子链上带有的阳离子基团起到电中和作用，使含油污水易于破乳除油，而疏水基团能增强颗粒的疏水性能；润湿反转剂能改变颗粒的润湿性，增强气泡与颗粒的粘附能力；起泡剂在水面能形成强度较大的泡沫层，起阻止带气絮粒向下翻动的作用。

This paper deals with different ways to depolymerize the chitosan into water soluble low molecular weight polymer.Molecular weight of water soluble low molecular weight chitosan was determinated by GFC.

探讨并比较了壳聚糖解聚成水溶性低聚物的不同途径，用GFC方法测定了水溶性低聚物的相对分子质量，证实选用NaNO2作解聚剂解聚效果良好。

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。
