一倍半

As Princeton bioethicist Peter Singer notes in his new book, if we fed that grain to the 1.4 billion people who are living in abject poverty, each of them would be provided more than half a ton of grain, or about 3 pounds of grain/day － that's twice the grain they would need to survive.

正如普林斯顿大学生物伦理学家彼得辛格在其新书指出，如果我们将此谷物粮食餵养活在赤贫中的十四亿人，将可供给每人超过半吨的谷物，或约一天三磅的谷物那是两倍於其维生所需。

Another way of stating this same relationship is to say that the length of the string is equal to an integral number of half wavelengths.

这种关系的另一种描述是，线的长度应等于半波长的整数倍，即是线的两个固定端正好为驻波的波节。

I think a bird needs a cage at least one and a half times its untrimmed wing span in at least two, but preferably, three dimensions.

我觉得一只鸟需要的一个笼子至少要一个半工作日，它们未切边的翼展部分需要两个工作日，但最好是三倍大的体积。

For the E. coli lac operon, write the partial diploid genotype for a strain that will produceβ-galactosidase constitutively and permease by induction.

以大肠杆菌的乳糖操纵元为例，请写出一菌株的部分二倍体基因型：β-半乳糖苷酶是组成型表达的，透过酶是诱导表达的。

It took Cockcroft and Walton five years to build a machine that worked. Finally, in April 1932, they had a machine that produced a steady stream of hydrogen nuclei with an energy of about half a million volts. They were carefully measuring the quality of the stream, in no hurry to begin doing nuclear experiments. On the morning of April 13, Rutherford came into their room, saw what they were doing, and lost his temper. He told them to stop wasting their time and do some science. The next day, Cockcroft was occupied with other business. Walton was alone in the laboratory, ready to do the first experiment, using his hydrogen nuclei to bombard a target made of the light metal lithium. The result was spectacular. The lithium nuclei were split in two and fell apart into pairs of helium nuclei.

用了五年时间，考克饶夫和华尔顿建造出了第一台能运行的加速器，最终，在1932年，他们制造出了能够提供稳定氢粒子流的加速器，粒子能量大约为50万伏特，他们并没有急着做核试验，而是精心测量了粒子流的性质，4月13日清晨，卢瑟福来到他们的房间，看到他们还在测量，大发雷霆，告诉他们停止浪费时间，开始科学研究，第二天，考克饶夫就被安排了其他事情，只剩华尔顿一个人在实验室里，准备做第一次实验，用他的氢粒子流轰击用轻质金属锂作的标靶，结果极为壮观，锂原子被分裂成两半形成一对氦原子，氦原子释放出的能量比氢原子注入的多达三十倍！

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
