The purpose of this paper is to solve the problem of high water cement ratio during construction and low water cement ratio during solidification 摘要目的通过将电渗技末引入到混凝土施工过程，解决混凝土工程中施工要求的大水灰质量比与使用性能要求的小水灰质量比之间的矛盾问题。
The optimal synthetic conditions obtained was n ( dac ) : n ( am ) = 2 : 3 , v ( oil ) : v ( water ) = 1 : 1 . 2 and redox initiator or high water - soluble initiator 在单体物质的量比为2 : 3 ，油水体积比为1 : 1 . 2 ，引发剂为氧化还原引发剂或高效水溶性引发剂的条件下，得到了溶解迅速且絮凝效果好的产品。
This system employed ch2cl2 as the initiator , the reaction mixture of 1mol equiv . of dichloride iron ( fecl2 . 4h2o ) and 2mol equiv . of triphenylphosphine ( pph3 ) as the catalyst 此体系以结构简单的二氯甲烷为引发剂，以物质的量比为1 2的四水合氯化亚铁与三苯基膦的反应产物作催化剂。
" appointments for procedures for parents ' day have increased by over 50 percent from five years ago , " said lim ee - seok , the president of t a large cosmetic surgery facility in seoul 首尔一家大型手术美容机构主席利马?埃苏克说： “今年双亲节预定的手术量比5年前增加了百分之五十。 ”
According to tessa hill , a geologist at the university of california , davis , more methane is released into the atmosphere from ocean deposits during periods of warming than previously thought 根据加州大学的研究，在全球变暖期间，海洋中储存中的甲烷气体的释放量比以前想像的更多。
Geohiong ( kaohsiung ) ' s department of health found that the blood samples collected from 1000 school students last year show a significantly higher amount of lead than students in the us and japan 高雄市卫生局旧年给一千耶三年仔学生囡仔抽血,发现讲血内面铅耶量比米国及日本耶学生加足? 。
The analysis shows that the average annual runoff volume has a little increase due to human activities after management , but the average annual sediment production has greatly decreased 通过分析发现，治理后流域内的人类活动使年均径流量比治理以前略有增加，而年均输沙量却比治理以前大幅度减少。
The results showed that the fluidization air velocity was the most important factor for the average mass ratio of powder and gas in the conveying , and that the least important was the agitator vertical height 试验结果表明，对于平均输送固气质量比，流化风速的影响最大，搅拌棒提升高度的影响最小。
Companies also have a stake in exaggeration , as in the recent case of the royal / dutch shell group , which admitted that its “ proven reserves ” were 20 percent less than originally stated 石油公司本身也参与这样的夸大行为，最近的例子是荷兰皇家壳牌石油集团承认其确定蕴藏量比当初宣称的数字少20 % 。
