More levels of nano-SiO〓 lead to larger particle size. An increase in polymerization reaction temperature causes the decrease in coagulum and increase in viscosity and particle size, and the nano-SiO〓 has same effects at certain temperature. When the levels of hydrophilic monomer acrylic acid and hydroxylethyl methacrylate in core composite are increased, the particle size of emulsifier-free emulsion decreases, in spite of the presence of nano-SiO〓.

无皂乳液具有单分散性好、表面洁净、成本低廉、不影响产品性能的特点,首次研究了含或不含纳米粒子的含羟基和羧基的丙烯酸无皂乳液聚合,发现含或不含纳米粒子的无皂乳液聚合后的粒子粒径较大,具有单分散性;较多的纳米粒子导致较大的乳液粒径;反应温度升高,凝聚物含量下降,而乳液粘度和乳胶粒粒径增加,在相同的反应温度下,纳米粒子降低了聚合过程中的凝聚物含量,增加了乳液聚合物的粘度和粒径;不论纳米粒子是否存在,当无皂乳液核组成中亲水单体AA和HEMA用量增加时,乳胶粒粒径均减少。

First of all,we tested the germination and water uptake rate of 47 species typical xerophil seeds grow up in north China from 20 families,38 genuses under sufficient water and different Grads water stress by high-molecular-weight polyethylene glycol(PEG6000).The results show that Xerophil seeds from the same habitat exhibited similar patterns in response to water stress.Xerophil seeds from arid community were stronger in germination and imbibition than that from other two communities under serious water stress,whereas Xerophil seeds from humid community were sensitive to any degree of water stress.Namely,the seeds live in arid habitat possessed high germination and quickly water uptake in sufficient water or any degree of water stress,but the others grow up in humid habitat shown significant difference which germination and water uptake well under sufficient water but inhibited even if slight water stress.

首先,我们通过对20个科,38属,47种旱生植物种子在水分充足和不同梯度的干旱处理(聚乙二醇PEG6000)条件下的萌发率及吸水率实验发现,当水分胁迫强烈时,分布于干旱沙漠地区的植物种子其吸水率和萌发率都高于半干旱和湿润地区的植物群落,相反,湿润地区植物种子的吸水率和萌发率对任何的水分胁迫都表现出敏感的响应趋势,也就是说,生境恶劣的植物种子在较强的干旱胁迫下,仍然保持了较高较快的萌发率及吸水率,水分充足与水分缺乏时无显著差异,而生境相对较好的植物种子在水分充足情况下萌发与吸水良好,但在干旱胁迫时则受到明显抑制,水分充足与水分缺乏时差异显著。

The exchange of substances between deposited sediments and overlying water must also pass through the DBL. In this study, two series of flume experiments with and without wind blowing conditions were conducted to study the salt release process from sandy sediments in a polder reservoir. The thickness of DBL was directly measured. The experimental salt fluxes through the DBL under the two wind conditions were inter-compared and compared with the estimations using the Fick's first law in an effort to explore the role of DBL in contact inhibition of salt release.
