天文学

"A height of between 80,000 and 90,000 feet is as much as can reasonably be expected, and so balloon-borne instruments can contribute little to either ultra-violet astronomy or X-ray astronomy."

它们可望升到的最大高度为80，000至90，000英尺，因此球载仪器无法对紫外天文学或X射线天文学作出贡献。

To bring about a shift in how Astro 101 is taught similar to that motivated by Hake's study of introductory-physics teaching, we conducted a national study in collaboration with instructors who agreed to use the LSCI, to determine the effectiveness of various teaching strategies in Astro 101 classes.

为了使天文学101的教学方法发生转变，使之类似于黑克在基础物理学研究中所推行的方法，我们跟同意使用 LSCI 的教师协作，进行了一项全国性的研究，以便确定在天文学101的课堂教学中各种教学策略的效果。

A new science, Radio Astronomy, has emerged, and it is very closely allied to astronomy, astro- physics

出现了一门新兴学科----无线电天文学，它与天文学、天文物理学和物理学关系密切。

The motives for his introduction of an astronomical system different from that of Schall could also be two-faceted. Firstly, under the influence of the dispute between Lansberge's Copernican school and the Tyconic school in Europe, he apparently became a sympathizer of Lansberge's system. Secondly, being quite aware of the serious errors of Tychinic astronomy in some calculatoins, like a number of other Jesuit Fathers doing, Smogulecki was pobably trying to replace it with Lansberge's system, which he believed to be more exact.

至于他为什么要介绍一种不同于弟谷体系的天文学系统，原因也有两个方面：首先，他明显受到当是欧洲哥白尼和弟谷两大天文学派之间的论战的影响，并且对哥白尼学派的主张持同情态度；其次，于许多入华耶稣会士一样，穆尼阁很明白，弟谷体系在天文计算中仍然存在很大误差，所以想用他认为更加精密的兰斯伯格的天文学系统来对它加以取代。

Finally, however, Maria Mitchell did become the first professor of astronomy at Vassar, and was at the same time the first woman to teach astronomy in any American college.

可是，最后玛丽亚确实当了瓦萨学院第一个天文学教师，同时也是美国所有的学院中讲授天文学的第一个妇女。

Astronomy was of old standing in Babylonia, and the standard work on the subject, written from an astrological point of view, later translated into Greek by Berossus, was believed to date from the age of Sargon of Akkad.

天文学在古老的巴比伦尼亚中，处于从属地位，很多有关天文学的作品都以占星术的观点来写，据说是来自于阿卡德的萨尔贡年代，后来由贝罗索斯翻译成希腊语。

We tried hard to understand his astronomical work as a whole in order to discuss more thoroughly the reason of the failure of the Chinese traditional calendrical astronomy in the calendar reform in the late Ming Dynasty.

一些学者对明末传统历法复兴的有关问题以及邢云路的天文历法工作进行过研究和探讨，该文则将邢云路的工作看作一个整体放在明末传统天文学复兴和历法改革的背景中进行细致讨论，力图对他的工作形成整体性的认识，以期深入探讨传统天文学在明末改历中失败的原因。

On the other hand, however, the book already made Smogulecki a "dissident" both within and without the Jesuit circles in China, given the sensitive role of calendrical astronomy in both the Chinese society and the Jesuit mission to China. The fate of this "dissident" and his book within the Jesuit circles affords quite for thought.

不过，尽管如此，由于天文学在中国社会以及耶稣会传教工作的地敏感地位，穆尼阁对汤若望引进的天文学系统的批判实际上已经使他成为耶稣会中的&异议分子&，而这位&异议分子&和他著作在耶稣会中的命运也颇为耐人寻味。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
