您要查找的是不是:
- By hydrolysis of poly(tert-butyl methacrylate)s, amphiphilic polymers with dodecyl phenyl as hydrophobic end and poly(methacrylic acid) segment as hydrophilic end were obtained. 将该聚合物水解,得到了以十二烷基苯基为疏水端、甲基丙烯酸链段为亲水端的两亲性聚合物。
- In the condition of oil wet, the micro-residual oil exists in blocklike dendrite-residual oil forms. 油湿条件下,微观剩余油以连片的枝状剩余油形成存在。
- In general, the method of compaction has a significant effect on the compacted clayey soil when the compaction is conducted on the wet side of optimum. 地质勘测包括确定施工现场地表下面的土壤和岩石成分、土壤的性质、基岩的深度以及有无断层和地下河流。
- Part of bio-enzyme adsorbed on the surface alters the wettability of rock(turn oil wet to water wet), decreases oil flow resistance and increases oil's flow properties. 部分生物酶吸附在岩石颗粒表面,改变岩石的润湿性(由油湿改为水湿),降低原油流动阻力,增加原油的流动性;
- Since the mid-latitude regions located in the north sub-tropical monsoon zone, the temperature cool and wet side, each rising 100 meters above sea level, the season went up 3 - 4 days. 由于该地区位于中纬度北亚热带季风区,气温偏凉而且多雨,海拔每上升100米,季节相差3--4天。
- Parts which are oil wetted should also require Level 2 residual magnetism. 同样,被机油浸润过的零部件也需进行二级剩磁检测。
- Rather than staying dissolved in the bulk liquid, surfactants prefer to gather around the surface of a bubble with their hydrophobic ends aimed into the gas and their hydrophilic ends stuck in the liquid. 因此,表面活性剂不会乖乖溶解在液体中,反而是喜欢群聚在气泡表面,让疏水端对准气体,而亲水端则一头栽入液体中。
- The accident put an untimely end to the party. 意外事故使聚会匆匆结束了。
- The boys were itching for the lesson to end. 那些男孩子们渴望下课。
- After the wettability of oil sand is changed to oil wetting with silicone oil, the adsorbance of surfactant would increase. 用硅油使油砂润湿改变后,表面活性剂在油湿性油砂的吸附比在水湿性油砂上吸附大。 分析了表面活性剂在油砂上出现最大吸附的机理,分两步建立了表面活性剂在大庆油砂上的吸附模型。
- It's natural to slack2 off towards the end of a hard day's work. 一天紧张工作快结束的时候有些放松是自然的。
- The company declared a large dividend at the end of the year. 公司在年底宣布分发高额股息。
- The army was disbanded when the war came to an end. 战争结束时,军队即被解散。
- The two teams were all square at the end. 最后两队以积分相同而结束。
- Are there any exams at the end of this term? 这个学期期末有考试吗?
- The battle finally brought the war to an end. 这一仗使这场战争终告结束。
- The rent is due at the end of each quarter. 缴纳租金以每季度末为期限。
- Wasteful people usually end up in debt. 挥霍浪费者最后往往负债。
- A year in America will cost you no end of money. 在美国住一年要花很多的钱。
