表示评述 主题 讨论 评价 展望的科技英语 I（741-780） 741. A substantial review of the properties of the stratosphere and mesosphere has been given by Murgatroyd (1970). 关于平流层和中间层大气的性质在Murgatroyd（1970）的论文中曾作了详尽的评述（回顾）。 742. This review is no exception and is more a quest for a single dominant mechanism that is able to account for many observations than it is a balanced exposition of the pros and cons of all mechanisms heretofore advanced but still not disproved. 这一回顾（评述）也不例外，与其说它是探求一个可以说明许多观测事实的主要机制，不如说它是对到目前为止提出的但仍未被否定的所有机制提出的正反两面意见的不偏不倚的介绍。 743. Sudden stratospheric warmings have attracted researcher’s attention ever since their discovery in the 1950s. Reviews include Holton (1963), Smith (1970)… 平流层突然增暖自五十年代发现以来一直为科学家们所注意。这方面论文有Holton(1963), Smith (1970)。。。。。。（以及其他人）。 744. The origin of electrification in clouds is an old and still unsolved problem. Earlier views of this subject (see, e.g., Moore, 1977) are often biased in favor of a particular mechanism for electrification. 云中起电的缘由是一个古老但仍未解决的问题。早期这一课题的观点（例如可见Moore,1977），因倾向于某一特定起电机制而经常有所偏颇。 745. There has been substantial theoretical interest in free-electron lasers (FEL) for the last decade. 在过去10年对自由电子激光一直有着浓厚的研究兴趣。 746. Recently there has been some renewed interest in the influence that the stratospheric mean wind may have on the tropospheric circulation. 近年来，科学家们对关于平流层平均风可能对对流层环流具有的影响产生了进一步的兴趣。 747. The instrumentation problems have been a major concern in development of synchrotron radiation research. 在同步（加速器）辐射研究中，仪器设备问题一直是重点。 748. Recently this topic has been addressed in the context of linear planetary wave models by among others. 尤其要指出的，最近这个课题由Trenberty (1983)和Appet (1983)采用线性行星波模式进行了探讨。 749. The interaction of intense electromagnetic beams with the atmosphere has been the subject of a number of investigations over the past decade. 强电磁束与大气的相互作用在过去十年一直是许多论文讨论的课题。 750. Few subjects in the atmospheric sciences have been the subject of more controversy than has the subject of sun-weather relation. 在大气科学中几乎没有什么课题比太阳—大气关系的课题更富有争论
