Not content with confining themselves to their degree subject, 59 percent of incoming students expressed a desire to pursue a secondary field of study, and 36 percent hoped to learn a language.

由于不满足于局阴在自己的专业上，有59%的新生表示出一个愿望，ꢜ就是他们要从事其他领域的研究。有36%的人希望学习一门语言。

At low magnetic field, the effects of magnetic-field-induced confining potential on the main features of the excitonic spectra are negligible.

在较低磁场下，其引入的限制势对激子吸收谱的主要特性的影响可以忽略。

At the same time, that gas must be prevented from touching the walls of the reactor by confining it in a powerful magnetic field known as a magnetic bottle.
