二聚的

A year ago, at a get-together of a dozen girlfriends from college, I saw my old friend, Therese Gibson.

一年前，在十二位女大学生举行的一次聚会上，我看到了我的老朋友，特里萨·吉布森。

It is the most common form of PVDF and the most thermodynamically stable.

它是聚偏二氟乙烯的最常见晶型，也是热力学最稳定的晶型。

The capacity of combination between monomer silicic acid and monomer aluminum was weak, while it was stronger between the polymer silicic acid and monomer aluminum and the products were mainly bidentate or tridentate coordination compounds.

单体硅酸与单核铝的结合能力较弱；聚硅酸与单核铝的结合能力则较强，反应产物主要为二啮或三啮配合物。

The conversations (below 60%) of these polymerization reactions are much lower than those of TPH and DCB, indicating that the trimerization is favorably promoted by the activation of strong electron-withdrawing substitutents in the para-orientation.

自制二腈聚合转化率均低于60%，低于TPH和DCB的转化率，说明吸电子对位取代基有利于氰基的三聚反应。

Objective To study a new method of preparing acellular porcine valved conduits by decellularization with poly ethylene glycol and to observe the change of mechanical properties.

目的 探讨聚乙二醇法在生物带瓣管道准备中的应用价值，比较PEG去细胞前后带瓣管道的物理特性。

We designed new soluble poly(2,6-anthracene vinylene),and the structure and some properties were characterized by ~1H NMR, DSC and TGA and GPC.

本文以我们新近合成的2，6-二甲基蒽为起始原料，在国际上首次设计合成了可溶性的聚2，6-蒽基乙烯，对各中间体和目标聚合物进行了必要表征。

The different adjuvants affected suspended rate of 15% triadimedon wettable powder in the study.

通过对 15 %三唑酮可湿性粉剂不同配方悬浮率的研究发现，加入聚乙二醇 6 0 0 0 ，其热贮之后的悬浮率仍≥ 6 5 %。

n thes paper, the oligomers with different molecular weight of monohydroxylpolyethersulfones were synthesized in solution and the optimum condition ofpolymerization was obtained; With phase transfer catalyst method,the oligomerswas obtained and transformed to monovinylpolyethersulfones macromer. Its structure was characterized with IR and 1H-NMR.

本文采用溶液法以单酚（4－氯－4'－羟基二苯砜）为原料合成了不同聚合度的单酚低聚体，得到了控制聚合度的最佳聚合条件；用相转移催化剂法成功地将单酚转化为单烯大分子单体，并用IR、1H—NMR对其结构进行了表征；测定了双键官能度均在1.90以上。

A high-resolution video camera, along with an infrared camera for navigation, was placed in the front of the craft along with three light-emitting-diode arrays for fill lighting and two quartz halogen lamps for spotlighting.

一台高解析度摄影机放置在小船的前方，另外还有一台导航用红外线摄影机、三排发光二极体负责提供充足的照明，以及两个石英卤素灯用于聚光。

A sample (660 mg ) of an oligomeric protein of Mr 132,000 was treated with an excess of l-fluoro-2,4-dinitrobenzene (Sanger's reagent) under slightly alkaline conditions until the chemical reaction was complete.

一分子量为132，000的660mg寡聚蛋白样品，在弱硷性条件下用过量的1-氟-2，4-二硝基苯处理，直到反应完成。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
