彗星

Stardust's cometary and interstellar dust samples will help provide answers to fundamental questions about the origins of the solar system.

星团的采样的彗星和星际尘埃样本将有助于回答关于太阳系起源的一些基本问题。

We do have a flight spare that we could practice with, but we know from our experience with the cometary aerogel that it has changed somewhat in space; it has become more brittle .

我们确实有大量可供练习的备用品，但是我们从彗星尘埃的凝胶那里得到的经验是：凝胶在太空里发生了一些变化，变得更加易碎了。

This cometary debris – bits of ice – create a meteor shower.

彗星留下的残骸即碎冰，便形成了流星雨。

And in some ways this looks consistent with the mineralogy/petrology studies that have been done on the cometary Stardust samples – I'll cover that paper too.

从某种意义上说这看起来与对彗星尘埃进行的矿物/岩石学研究相一致，我会报到那篇论文的。

The goal of TAOS project is measuring the number and size distribution of Kuiper Belt Objects down to a few kilometer size of cometary nuclei.

中美掩星观测计画的目标为测量彗星核大小至几公里的古柏带天体之数量与大小分布。

In addition, Stardust carried an equally important payload on the opposite side of the cometary collector: the first samples of contemporary interstellar dust ever collected.

此外，星尘号彗星收集器的背面还携带着同样重要的载荷：第一次采集到的同一时期星际尘埃样品。

Holmes' outburst could be due to a sudden exposure of fresh cometary ice or even the breakup of the comet nucleus.

Holmes彗星爆发的原因可能是彗冰的突然暴露，甚至可能是彗核分裂。

The article said that Herschel had developed a "new theory of cometary phenomena"; he had discovered planets in other star systems; and he had "solved or corrected nearly every leading problem of mathematical astronomy ."

文章说赫舍尔已经发展了"彗星现象的新理论"，发现了其他星系的星球，而且他已经"解决并更正了几乎每个数理天文学的主要问题"。

In England the middle Baroque produced a cometary genius in Henry Purcell, who, despite dying at age 36, produced a profusion of music and was widely recognized in his lifetime.

巴洛克中期的英格兰有一位如彗星划过般的天才音乐家普塞尔，尽管只活了区区36个年头，但是他创作了大量的音乐作品并在他的有生之年得到广泛的认可。

Also in this dissertation, in order to assist the project of simulating cometary spectra of H〓O〓 as proposed by Kawakita and Watanabe Ap.

为了协助Kawakita和Watanabe[Ap.J.574（2002）L183-L185]提出的H〓O〓彗星光谱的理论模拟和进一步标识H〓O〓的实验谱线，本文首次利用偶极矩的从头计算结果计算了振动跃迁矩及谱线强度。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
