1.He said he visited MaSeR periodically to ensure that the material was fully recycled.
他说他曾定期去参观过MaSeR以保证那些原料被完全回收利用。
2.During the early nineteen-fifties a remarkable device known as the maser came into being through the efforts of a number of scientists.
在本世纪五十年代初，通过许多科学家的努力，出现了一种引人注目的器件，叫做微波激射器。
3.Last year the art critics praised Jonas as if he were a maser, but he turned out to be a nine day's wonder.
去年艺术评论家们还赞颂乔纳斯为大师呢，但后来证明它只是一个昙花一现的人物。
4.Figuratively, one may imagine the radiation of such a spherical maser as resembling a little hedgehog.
可以很形象地把这种球状脉塞源的辐射想象为一个小刺猬球的样子。
5.Hydrogen absorbing alloys have been widely used today to store the hydrogen, they also can be applied to the Hydrogen Maser.
合金储氢方式现在已被广泛采用，这种储氢方式也可应用于氢原子钟。
6.Although he thought of the key idea in 1951, the first maser was not completed until a couple of years later.
尽管在1951年关键的想法已经产生，第一个微波激射器还是直到二年后完成。所以应该选C。
7.A maser is a collection of molecules -- in this case, water -- that amplifies light into a powerful beam.
一个脉泽就是一组分子（在这个话题下就是水分子），它会把光线放大为强大的光束。
8.In the case of this mega-maser, the light was emitted when the universe was very young -- about 10% of its current age.
在宇宙还是很年轻（大约是它目前年龄的10%）的时候，光线从这座巨型脉泽中发出。
9.By studying the size and temperature of the mega-maser itself, we can try to understand how it formed.
通过研究巨型脉泽自身的大小和温度，我们可以设法搞清楚它是如何形成的。
10.His discoveries, which won him the Nobel prize, led to the caesium atomic clock and the hydrogen maser.
这一获得诺贝尔奖的发现产生了铯原子钟和氢微波激射器。
