查询词典 meteor

Of course, the meteor was part of the annual rain of dust from periodic Comet Swift-Tuttle known as the Perseid Meteor Shower.

斯威夫特－塔特尔彗星周期性回归后，遗留下的尘埃形成一年一度的流星雨，也就是著名的英仙座流星雨，当然，这颗流星就是其中的一部分。

Explanation: This bright and colorful meteor flashed through Tuesday's early morning skies, part of the annual Perseid Meteor Shower.

说明： 这颗来自英仙座流星雨的明亮多彩流星，在星期二掠过了清晨的长空。

The Perseid meteor shower has been observed for about 2000 years, with the first known information on this meteor shower coming from the Far East.

英仙座流星雨已经看到了大约2000年，第一已知信息关于这个流星雨来自远东。

Meteor in the majority of them fell to the ground about 60-70 km height Will be burning out, and by our Sky Survey camera tracking shot of a meteor that this is a very slow rate of growth fell to the ground about 37 kilometers away from the high, it at least a few films or meteorite impact to the scene.

大多数流星在它们降到到地面大约60-70公里的高度时就会被燃烧掉，而由我们的巡天摄像机跟踪拍摄的这一颗流星却以相当缓慢的速度降到了距离地面大约37公里的高度处，因此它至少有一片或几片陨星撞击到了场面。

For observers in northern hemisphere, we do not need to wait until wee hour for the show. The meteor shower is known as Geminid Meteor Shower because the meteors are radiating from the constellation of Gemini.

这时候所见的流星，多数原自于双子座，故被称为双子座流星群；而发射出流星的那一处则是辐射点，靠近&北河二&这颗亮星。

An effective approach based on MTI filtering to eliminating nontransient meteor trails interference is presented using the theory of eigen subspace after analyzing the feature of the meteor trails in detail.

针对流星余迹干扰的特点，利用特征子空间理论，提出了有效消除非瞬态流星余迹干扰MTI滤波的方法。

However, the NASA Web site quotes meteor expert David Asher from the Armagh Observatory in Northern Ireland as saying that people "are probably seeing the Taurid meteor shower."

北爱尔兰阿尔马天文台的流星专家戴维·阿舍尔表示，人们看到的火球可能是金牛座流星雨，这种流星雨往往会在每年10月底到11月初这段时间里出现。

The spectrum analysis shows that ① Infrasonic waves produced by meteor are mostly very short, lasting one to five minutes;②Periods of the infrasonic waves range mostly from 40 to 408 seconds, and a few waves range from 40 to 480 seconds;③ During 7:21 p.m. to 8:41 p.m. on Nov. 17, the infrasonic waves were much denser. After 8:41 p.m., the waves become more and more sparse, all waves conform to those observed with naked eyes;④ Amplitudes of infrasonic waves from meteor differ significantly from each other (weaker ones below 5 to 10 Pa, medium ones from 10 to 20 Pa, and stronger ones from 20 to 40 Pa). Two of the strongest ones reach 75 Pa and 50 Pa respectively around 7:28 p.m. and 8:07 p.m. on Nov. 17. An explanation of above results is given.

频谱分析结果表明：①各流星产生的次声波大都很短暂，持续时间为1~5min；②流星次声波的周期大都在40~408s；③在1998年11月17日19：21-20：41期间流星次声波仍很密集，20：41后才变得越来越稀疏，恰与肉眼观测结果相符；④流星次声波的振幅彼此相差很大，较弱的在5~10Pa，中等的在10~20Pa，较强的在20~40Pa，最强的两个波在11月17日19：28和20：07前后分别达到75Pa和50Pa。

The phenomenon caused meteor particles called meteoroids, so meteor and meteoroids are two different concepts.

造成流星现象的微粒称为流星体，所以流星和流星体是两种不同的概念。

It will make the characters of ethnical and local culture eliminated. On the other hand, this tendency stimulates the arousal of the selfconsciousness of ethnical and local culture.
