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. 將該聚合物水解,得到了以十二烷基苯基為疏水端、甲基丙烯酸鏈段為親水端的兩親性聚合物。
- In the condition of oil wet, the micro-residual oil exists in blocklike dendrite-residual oil forms. 油濕條件下,微觀(guān)剩余油以連片的枝狀剩余油形成存在。
- 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. 地質(zhì)勘測包括確定施工現場(chǎng)地表下面的土壤和巖石成分、土壤的性質(zhì)、基巖的深度以及有無(wú)斷層和地下河流。
- 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. 部分生物酶吸附在巖石顆粒表面,改變巖石的潤濕性(由油濕改為水濕),降低原油流動(dòng)阻力,增加原油的流動(dòng)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. 由于該地區位于中緯度北亞熱帶季風(fēng)區,氣溫偏涼而且多雨,海拔每上升100米,季節相差3--4天。
- Parts which are oil wetted should also require Level 2 residual magnetism. 同樣,被機油浸潤過(guò)的零部件也需進(jìn)行二級剩磁檢測。
- 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,表面活性劑不會(huì )乖乖溶解在液體中,反而是喜歡群聚在氣泡表面,讓疏水端對準氣體,而親水端則一頭栽入液體中。
- The accident put an untimely end to the party. 意外事故使聚會(huì )匆匆結束了。
- The boys were itching for the lesson to end. 那些男孩子們渴望下課。
- After the wettability of oil sand is changed to oil wetting with silicone oil, the adsorbance of surfactant would increase. 用硅油使油砂潤濕改變后,表面活性劑在油濕性油砂的吸附比在水濕性油砂上吸附大。 分析了表面活性劑在油砂上出現最大吸附的機理,分兩步建立了表面活性劑在大慶油砂上的吸附模型。
- It's natural to slack2 off towards the end of a hard day's work. 一天緊張工作快結束的時(shí)候有些放松是自然的。
- The company declared a large dividend at the end of the year. 公司在年底宣布分發(fā)高額股息。
- The army was disbanded when the war came to an end. 戰爭結束時(shí),軍隊即被解散。
- The two teams were all square at the end. 最后兩隊以積分相同而結束。
- Are there any exams at the end of this term? 這個(gè)學(xué)期期末有考試嗎?
- The battle finally brought the war to an end. 這一仗使這場(chǎng)戰爭終告結束。
- The rent is due at the end of each quarter. 繳納租金以每季度末為期限。
- Wasteful people usually end up in debt. 揮霍浪費者最后往往負債。
- A year in America will cost you no end of money. 在美國住一年要花很多的錢(qián)。
- It's no fun to find oneself at the end of the rope. 山窮水盡,可不是好玩兒的。
