乙撑

Using ethylamine as a preswelling agent, a detailed study of the effect of solvent, amount of amine added, reaction time has been carried out. Among these the dielectric constant of the solvent has been found to be the most important factor.

以乙胺为预撑剂，详细考察了溶剂、胺的加入量、反应时间等因素的影响，发现溶剂的介电常数是影响这类晶体剥离和嵌入的最重要的因素。

Purpose To study the therapeutic dose of 153Sm-EDTMP for interradiation.

目的 探讨153Sm-乙二胺四甲撑膦酸内照射治疗剂量。

Objective With Monte Carlo and MIRD methods respectively, the absorption dose of ^153Sm- EDTMP was calculated in different target organs of nasopharygeal carcinoma patient so as to explore their clinical value.

文章摘要：目的以153Sm-乙二胺四甲撑膦酸（153Sm-EDTMP）治疗鼻咽癌多发性骨转移为例，分别用蒙特卡罗法（Monte Carlo，MC）和MIRD方法计算153Sm-EDTMP治疗后病灶和骨髓等靶器官的吸收剂量，探讨其临床应用之不同。

The corrosive nature of the sterilant, whether it is clean steam, formaldehyde, peroxide or ethylene oxide, has caused problems with gaskets and seals.

灭菌剂的腐蚀性能，不管是清洁蒸汽、甲醛、双氧水还是乙撑氧，都能引起垫圈和密封的问题。

If the fluidity of the injection was bad, the appearance of the product would berough, brittle, and very difficult to satisfy the actual application. In order to improve thefluidity of the melting-body in full filling condition, different types of lubricant function were used in the paper. Though the metallic soap might enhance the fluidity of themelting-body, the dosage was huge, which might cause drops on the mechanics intensityof the product, and cause magnet to be crisp and easy to crack.

为改善在高填充时熔体的流动性，研究了不同润滑剂的作用，金属皂类可以提高熔体的流动性，但用量较大，会导致产品的力学强度的下降，磁体脆而容易开裂，乙撑双硬脂酰胺可以提高熔体的流动性，复合材料的力学强度也较高。

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。
