水溶液

Surface tension of the calcium hydroxide solution is higher than that of water when the concentration of additive is the same.

但同浓度下，石灰水溶液的表面张力要高于水溶液的表面张力。

Based on these facts, the properties of films regenerated from new aq. alkali soluble cellulose/NaOH solution with sulfuric acid as coagulator were studied. The structure and morphology of the film was characterized by SEM, and also the influence of coagulator concentration on the film property was studied.

在此基础上，对新型碱可溶纤维素/NaOH水溶液体系在以硫酸水溶液为凝固剂时所成膜的性能进行了研究，采用SEM电镜对膜的结构与形态进行了分析表征，研究了凝固剂浓度对膜性能的影响。

The fry of black seabreamand giant sea perch with 4.0cm-8.5cm using the methods of dyeing, i.e., the fish immersed in the water solution containing comestible pigment, immersion in tetracycline, i.e., the fish immersed in the water solution containing tetracycline, and marking by spraying, i.e., the fish sprayed with fluorescent pigment spraying on the skin of fish, and double marking, i.e., the fish sprayed with fluorescent pigment spraying on the skin of fish after feed with tetracycline, and control group. The survival rates, mark retention rates and hydrology data were separately measured every three days for black sea bream and every two days for giant sea perch. The results were as follows.

本研究针对体长4.0cm-8.5cm的黑鲷及金目鲈的鱼苗采用染色法(将鱼只浸泡在含有食用色素的水溶液中)、四环霉素浸泡法(将鱼只浸泡在含有四环霉素的水溶液中)、喷枪法(利用高压喷枪将萤光色素打在鱼的表皮)以及双重标识法（四环霉素投餵法加上喷枪法）与一组空白组进行试验，黑鲷每三天一次、金目鲈每两天一次，调查标识后鱼只的时间别残存率、时间别标识残留率以及水质资料，结果如下。

The results indicate that the weak election-withdrawing group 4-hydroxymethyl in 4-position of pyridine in 4-HMDPA could weaken the fluorescence intensity of the lanthanide complexes. The contradistinctive experimental results show that the fluorescence intensities of these complexes are related to pH value of the aqueous solution and the dipole moment of solvent molecule: in the neutral aqueous solution,the fluorescence intensities of these complexes were strongest,while the less the dipole moment was,the stronger the fluorescence intensity was.

结果表明，在吡啶4位引入弱吸电子基团4-羟甲基会减弱稀土配合物的荧光强度；在水溶液中稀土配合物与溶液的pH值有着密切的关联，中性水溶液中荧光强度较大；分子偶极矩较小的溶剂中稀土配合物荧光强度较强。

In recent years, much hard work has been done by scholars from all over the world. These work has mainly involved the denaturation mechanism of proteins in water, in the solution with denaturant and in the solution with other matters.

近年来，国内外学者在此方面做了大量的工作，主要涉及蛋白质在水溶液中的变性机理、在有变性剂存在下水溶液中的变性机理及在含有其它物质水溶液中的变性机理。

By using a vitrating digital densimeter (DMA602/60), the densities of glycine and alanine in aqueous methanol, ethanol and propanol solutions were measured at 298.15 K, and the apparent molar volumes calculated. According to McMillan-Mayer approach, the volumetric interaction coefficients were evaluated.

用DMA602/60型震动管数字密度计测定了298.15 K下甘氨酸、丙氨酸分别在纯水和四个不同浓度甲醇、乙醇和丙醇水溶液中的密度，计算了相应的表观摩尔体积，用最小二乘法拟合了氨基酸在醇水溶液中的标准偏摩尔体积。

Outside the drug would depend on the status of the skin, water erosion or swelling, the use of 2% boric acid aqueous solution or aqueous solution of 0.1 lei佛奴Hydropathic, exudate and erosion after the disappearance of topical corticosteroid preparations, such as eczema cream, Qushi oil, cream, etc.

外用药要视皮肤病变状态而定，出水糜烂或红肿时，用2％硼酸水溶液或0.1雷佛奴水溶液湿敷，渗液与糜烂消失后，外用皮质类固醇激素制剂，如湿疹霜、祛湿油、肤轻松霜等。

Laboratory data indicate that the water solubility and injectivity of the polymer were good at reservoir conditions.

结果表明，该聚合物水溶液配制方便，将粉末状态的聚合物配制成1500mg/L的水溶液仅需2h。

We can do many interesting experiments in science class. That's why we like science class very much. However, some experiments are difficult and dangerous. For example, something acid and alkaline will erode our body. Besides, indicators are very dangerous. So, be very careful to do any experiments inscience class! This is our experiment in science class.

我们喜欢上自然课，因为上自然课可以做实验，我们的自然实验有些有趣，有些困难，不过全都非常好玩，可是有些实验会使我们得生命有危险，像水溶液实验，因为酸、碱性的水溶液，会是我们的身体腐蚀，指示剂也非常危险，所以做实验要非常小心，以上就是我们的自然实验。

Through treating 10-20 min with 60-80 times water dilution of the optimum formula emulsion, the corrected mortality of the fly eggs which were placed on the fresh kipper reached 100%, and the quality of dried kipper was affected little.

经最优配方乳化肉桂油的50~60倍水溶液处理，蝇卵校正未孵化率在95%以上，用该乳液的60~80倍水溶液浸泡接卵鲜咸眷10~20min，校正未孵化率达到100%，且不影响干咸鲞品质。

This paper demonstrated the impact on the environment today, an important factor is Education.
