masers n. 微波激射器;脉塞;量子放大器;分子增幅器(maser的复数形式)
- This paper will describe the performance of hydrogen masers used in Nanshan VLBI station.
这篇文章将描述上海天文台为中国VLBI网南山站研制的氢脉泽的性能。 - Before long, many other physicists were building masers and trying to discover how to produce stimulated emission at even shorter wavelength.
不久以后,许多其他的物理学家也正在制造微波激射并且试图发现如何产生更短波长的刺激发散。 - The team found that the masers seem to be orbiting the galactic centre faster than expected at those distances, meaning more mass is needed to keep them in orbit.
这个团队发现,脉泽环绕银河系中心的速度比它们所在位置应有的速度要快,这意味着它们需要更多的质量让自己保持在轨道上。
