水性

Form April to July, 1975, and 1977, a series of artificial stimulating precipitation experiments by seeding clouds with, metaldehyde and silver-iodine from the ground by the small rockets were carried out in Gutian reservoir region of Fujian province.

1975年和1977年4—7月，在福建古田水库地区进行了由小火箭携带介乙酸和碘化银播云的人工降水试验，采用区域回归随机试验方案，利用统计方法检验效果。试验对象主要是系统天气影响下的降水性层状云和积状云，以三小时时段为试验单元，总共进行了62次随机试验，其中实际作业31次，对比试验31次。

In the research of metal ion self-crosslinking latex, a lot of experiments proved that when 6% MAA, 2% methylol acrylamide and 0.5:1 of molar ratio of Zn2+/COO- by adding zinc acetate to adjust were used, hardness of film reached 2H, water resistance gaind 96h longer and other characteristics measured up coating standard.

在对金属离子自交联乳液的研究当中，由大量的实验得知：当MAA含量为6％，N-羟甲基丙烯酰胺含量为2％的乳液，加入的醋酸锌使Zn~(2+)／COO~-摩尔比为0.5：1时，乳液涂膜后硬度达2H，耐水性达96h以上，其它涂膜性质符合漆类标准。

The thin layer of microbiotic crusts with lower bulk density, lower density, higher soil porosity and higher water-holding capacity will markedly influence the soil hydrological processes, such as the processes of penetration, the interception, the redistribution and the evaporation of precipitation, which will threat the soil-water environment in Shapotou area.

容重较小、比重低、孔隙度高和持水性能强的薄层微生物结皮对土壤水文过程产生了深刻的影响。在沙坡头地区，微生物结皮改变了降雨在沙丘土壤中的渗透、再分配、拦截和蒸发等过程，并最终导致固定沙丘土壤水环境的恶化。

Micronization of irbesartan has been studied using an anti-solvent recrystallization method.

采用反溶剂重结晶法对疏水性药物依贝沙坦了进行微粉化研究。

This change corresponds to the formation of micelle-like clusters self-aggregated by the cholesterol moity once the CHD concentration exceeds 0.01mg/ml.

在此浓度之上，PNA的荧光屏强度大大增强，表明CHD分子中的胆固醇自聚集而形成了疏水性胶束状的聚集体。

Results showed that monobasic alcohol can decrease the micropolarity of β-CD cavity, but the formation constant of pyrene-β-CD inclusion complex is being larger, and polybasie alcohol had the opposite effects.

由于具有不同的尺寸大小的疏水性空腔，cD可与多种化合物形成包络物，已显示出在催化反应，化学仿生学等领域中的重要作用。

HC-402-2 Homogeneous catalyst for benzene hydrogenation is improved through removing water from the catalyst and reducing the content of emulsified material in nickelous isooctanoic acid cyclohexane liquor.

HC - 40 2 - 2型苯加氢均相催化剂经过改进，去除催化剂中的水份，降低异辛酸镍环己烷溶液中乳化物含量后，在保持加氢效果不变的前提下，大幅度提高了催化剂的抗水性能、延长了催化剂的使用寿命。

The hydrophobic and hydrophilic organic fractions each accounted for about 50% of DOC of the secondary effluent samples. Hydrophobic acids were the largest group accounting for 42%, followed by hydrophilic acids and non-acid hydrophilic matters at 26% and 24%, respectively; nonacid hydrophobic matters at 8% were the smallest group.

实验结果表明：当生化出水中有机物浓度以DOC表征时，水中硫水性物质与亲水性物质各占50%，其中疏水酸浓度最高，约为42%，其次为亲水酸和非酸亲水物质，分别占25%和24%，非酸疏水物质仅为8%。

But after the accumulation of experiences about the quality of water, this occasionality can be changed into some kind of necessity.

在水的自由状态下有很多意外的偶然性，但在对水性熟悉的经验积累后，这种偶然也会变为某种必然。

In this paper,the monomers including St and BA with strong waterproof property were employed to modify the traditional PVAc emulsion,and meanwhile draw into DAAM functional monomer in the copolymer system,will prepare out cross linking copolymer emulsion for ADH to improve the waterproof,oilproof and dry/wet mechanical property of fuel oil filter paper.

采用具有较强抗水性的苯乙烯、丙烯酸丁酯等单体对传统聚醋酸乙烯酯乳液进行共聚改性，并在共聚体系中引入双丙酮丙烯酰胺功能单体，制备出可通过外加己二酸二酰肼交联的外交联醋丙共聚乳液，以期提高燃油滤纸的耐水、耐油性和干湿态的力学性能。
