查询词典 zenith

But the only zones in which the moon passes the zenith, the point directly over the head of the spectator, are between the twenty-eighth parallels are the equator.

但是，月亮经过天顶点，也就是说它能够爬上观测者的头顶的地方，必须位于地球赤道和南北纬二十八度之间的地带。

The highest point; the zenith .

这位作家已经鼎鼎有名了。

Sartre's star was at this point at its zenith, but Derrida was later to repudiate most of French existentialism's legacy and in the long run it was his early encounters not with Sartre but with the anti-humanists Nietzsche and Heidegger which had the greatest impact upon him.

刚在自威尼斯回来的路上的查太莱夫人康妮，便私下和梅洛斯约好了上伦敦旅馆中去相会。肉与肉一行接触，她也就坚决地立定了主意，去信要求和克列福特离婚，预备和梅洛斯两人去过他们的充实的生活。

Surrounding the zenith (the point directly above the observer) and always at the same altitude as the Sun is a lovelyparhelic circle, caused by sunlight reflecting from ice crystals with nearly vertical faces.

在天顶的方向，有一个受到冰晶垂直面的反射形成的幻日，通常是与太阳同高，一般来说，如果你知道如何去观察它，日晕比彩虹常见多了。

Within the limitation of SBTART model, the paper is concerned with the preliminary study of the feasibility of determining total atmospheric ozone by scattered ultraviolet radiation from the clear zenith blue sky.

选用SBDART模式作为大气辐射传输计算模式，通过模拟计算和结果分析探讨无云的晴天、垂直对天顶观测的紫外前向散射反演大气臭氧总量的可行性。

The results showed that the red /blue color index during twilight changed evidently with AODs in lower atmosphere. When AOD was small, there was a maximum of the radiance at 450nm in the high view elevation angle. So the sky color at the zenith is blue. However, the maximum shifted to red wavelength (about 700nm) with the fall of view elevation angle.

计算结果分析表明，曙暮光时天空辐射强度的红蓝光颜色指数随近地层大气气溶胶光学厚度的变化显著；当τ较小时，太阳辐射随波长的变化显著，在高仰角450nm附近有极大值，天顶方向以蓝色调为主；而在低仰角极大值向红光方向移动。

Zenith Media has a well-performed year and maintaining and growing existing client relationships with like China Mobile and SGM.

Zenith Media has a well-performed year, and maintaining and growing existing client relationships with like China Mobile and SGM.

实力媒体在去年表现相当出色，与重要客户中移动和上海通用的合作关系良好，并进一步拓展。

The Eddington scheme is slightly more accurate in thicker optical depth region, while the two-stream DISORT is more accurate in the thin optical depth region where the solar zenith angle is less than 60 degree. Second, we compare the two two-stream schemes in a realistic atmospheric profile with gaseous transmission considered.

对于单层大气，Eddington 近似在光学厚度大的时候比二流离散纵标法更精确一点；而二流离散纵标法在光学厚度小且太阳天顶角小于60 度的时候更准确。

They reached Zenith at about three o'clock in the morning and went immediately to the home of the telegraph operator.

凌晨3点钟左右，他们到达了泽尼斯，并立即赶到了报务员的家里。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
