易用的

We have used GC to follow up the formation of epoxy acid and established the acidify condition; we have done series of parallel experiments to better the pivotal condensation reaction between acid and amine; In the cyclization step, we use cheap and available reagent-Lithium amide , rather than expensive LiHMDS, to proceed the reaction; and at last, we introduced green reagent-ozone to clear the phenyl group of nitrogen to avoid using heavy metal reagent-CAN. The total yield for this method is 29.8%.

通过GC监测，确定环氧酸的最佳酸化条件；对关键的酸和胺的缩合步骤，平行试验了多种条件；在环合一步，用价廉易得的氨基锂及催化量的HMDS代替昂贵的LiHMDS进行反应；氮上苯基的脱除采用臭氧，避免了重金属试剂-硝酸铈铵的使用，总收率为29.8％。

The system — the first of its kind in the world — does not predict quakes, but officials say it can give people enough time to get away from windows that could shatter, or to turn off ovens and prevent fires from razing homes.

该系统，是世界上同类产品中的第一个，它并不是用来预测地震，但是具官方发言人说，它可以给人们足够的时间逃离易碎的玻璃，关掉烤箱和阻止可能毁掉家的火灾。

The crowd represented every facet of cross dressing, from some male transvestites wearing women's clothes but making no attempt to look like a woman, to drag queens dressed in long evening gowns covered in sequins, with beautiful wigs and perfect make up.

人群描述穿的十字架的每个方面，从一些男易装癖者穿女装，但是没有尝试看起来象一名妇女，令人妖的是覆盖装饰衣服用的圆形小金属片的晚礼服，与一起美丽假发和完美补足。

Safariland's distributor in San Diego, Don Hacklander, regularly demonstrates the safety and ease ofcadet shooting 50 yard head shots. This simplicity of training, citizen safety through accuracy, and

圣地亚哥的&狩猎园地&的发行人——Don Hacklander——定期示范各种城区使用武器的安全与易用性，他从警察学院找来射击技术最糟的学员，让他们在15分钟内射击50码头靶。

All smaller than the traditional American bottom brackets seen on many older BMX bikes, these save weight, clean up appearances, and add ease of use with threads and straight push fit bearings.

所有小于传统的美国底部许多老年人小轮车的括号内看到，这些节省的重量，清理出场，并添加易用性和线程的使用和适合直推轴承。

Turok is hopeful that string theory and a related development known as the " holographic principle ", which shows that a singularity in three dimensions can be translated into a mathematically more manageable entity in two dimensions (which may imply that the third dimension and gravity itself are illusory).

弦理论及其相关的用三维方式描述宇宙奇点的全息图原理的进展，使塔洛克抱有希望，使他能将这些理论转化成数学上较易处理的二维实体（这可能意味着第三维和重力本身是虚幻的）。

But neoclassical theorists depart from the essence of the Keynesian aggregate theory when they try to develop it. They use static and comparative static method that is the Walras equilibrium, to explain the dynamic aggregate relations thatKeynes wanted to explain. In doing so, their theories fall into logical paradoxes and in order to avoid the difficulty neoclassical theory only can be applied to the barter economy.

而新古典理论家在阐释发展凯恩斯总量理论的过程中，背离了凯恩斯本人的初衷，用静态和比较静态的瓦尔拉斯一般均衡框架来解释凯恩斯要说明的总量关系，结果使理论陷于各种逻辑问题，为避免逻辑矛盾，该理论只适用于分析以物易物的实物经济关系。
