不变化的

The varying tendencies of partition coefficients of some compounds in aqueous or nonaqueous solvent systems by calculating the phase equilibria with universal quasichemical functional group activity coefficient model are predicted. These compounds included saturated and unsaturated fatty acids ethyl esters,N2,4dinitrophenylamino alcohols, pnitrophenyl glucosides and so on, with simple structures and much differences in polarity.

以饱和及不饱和脂肪酸乙酯、2，4二硝基苯胺基脂肪醇和对硝基苯基葡萄糖甙等结构较为简单、极性差别较大的溶质系列为研究对象，应用修正的通用基团活度系数模型，通过相平衡计算，预测了它们在含水或不含水的溶剂体系中分配系数的变化趋势，并与前人的工作进行了对比。

The version that people responded to the best talked about "air pollution" rather than "climate change"– because pollution is something visible that they could relate to, with strong connotations of dirtiness and poor health.

人们反响最好的版本用了"大气污染"而不是"天气变化"——因为污染是人们相关的可见的东西，有很强的肮脏和不健康的意思。

The key factor causing the variation of soil bulk density was the uneven distribution of soil texture.

土壤质地不均匀分布是引起土壤容重变化的关键因素。

For example, give yourself a week to give a twenty-dollar bill to someone you don't know.

举例来说，每一星期布施二十元给你不认识的人，并看看那星期当中有什麼变化？

"The three-man defence can be altered, but that will to win won't change."

The results show that, with the change of angle in fixed slenderness ratio and spacing of particles, the materials failure state is interface breakout and matrix crack.

结果表明，在保持颗粒长径比(2：1)和颗粒间距不变的情况下，随着θ的变化，不存在颗粒断裂的危险，材料的主要失效方式为界面脱离和基体开裂。

As for heads-I-win capitalism, the problem of asymmetric risk should shrink, because the rule changes needed to make the financial system safer will also remove unwarranted profits.

对总是一方赢的资本主义来说，不对称的问题应当会有所减小，因为使金融系统更安全所需的规则变化将会剔出不合理的利润。

Neither atmospheric scientists nor oceanographers can adequately account for the speed of the changes.

大气科学家和海洋学家都不能很好地解释变化的速度。

Methods:The clinical therapeutic effect was 0bserved and blood gas was analyzed before and 24hm after NIPPV for 20 patients with bronchial tube asthma who were not susceptible to routine therapy.

观察20例经过常规治疗效果不佳的支气管哮喘患者应用NIPPV治疗前、24h后临床疗效及血气变化。

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。
