Pictured above, the fireball was photographed streaking above Teton mountains behind Jackson Lake, Wyoming, USA. The Great Daylight Fireball of 1972 was possibly the size of a small truck, and would likely have created an impressive airburst were it to have struck Earth more directly.
上面影像拍摄的是火流星在美国怀俄明州杰克逊湖后方的提顿山脉上空。1972年巨大的白昼火流星大小可能类似一辆小卡车,可能会形成一次壮观的空中爆炸,或者直接撞击地球。

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea,a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious.
该文根据地海杂波与流星干扰在多普勒谱上的差别,提出了用FIR型高通滤波器滤除杂波使流星干扰凸显出来;再根据流星干扰的分布特点分段计算背景噪声均值,求取流星干扰检测门限;最后用杂波信号来插值流星干扰位置上的数据,消除因去除干扰造成的杂波相位不连续。

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea, a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious. Then a smart threshold is obtained from the minimum mean of different segments of background noise and used to detect the meteor trail echo. Finally the phase discontinuity of clutter from the meteor trail echo suppression is eliminated by substituting the data at echo positions with clatter.

From momentum equation and energy equation, the ablation profile of meteoroid with different radius in different velocity is calculated, and the variation of the ablating cut-off height is analyzed.
本文从流星颗粒的动量方程和能量方程出发,计算不同半径下的流星微粒在不同的注入速度下的消融剖面,并分析了流星消融截止高度的变化趋势。

The Quadrantid meteor shower and the meteor speed during the period of this meteor shower are successfully observed using the Wuhan meteor radar for the first time, and then the correlative questions of observing meteor shower using the all-sky meteor radar are also discussed.
利用武汉流星雷达,首次成功地观测了象限仪座流星雨及流星雨期间的流星速度,讨论了利用单站全天空流星雷达观测流星雨的相关问题。

The observational result shows that this Quadrantid meteor shower occurs between 0000 to 0800 local time in January 4, 2004, with meteor echoes peaking at 0400 local time. Moreover the meteor shower radiant derived from the meteor echoes plane, which is formed by the whole meteor echoes observed by the meteor radar during this shower, accords well with the theoretic radiant of this meteor shower.
从观测结果可以发现此次象限仪座流星雨发生在2004年1月4日的0000-0800LT,其中流星峰值出现在0400LT,而且通过流星雷达观测到的流星雨期间的流星回波平面推测得到的流星雨辐射点也与该流星雨的理论辐射点位置对应非常好。

Geminid Meteor Shower is one of the yearly attractions to astronomers as well as casual observers because of its hourly rate up to 100 meteors during the peak.
双子座流星群是长年倍受看好的流星群之一,无论是天文学家还是一般爱好者,都因为其极盛时期每小时可达100颗流星的盛况而精神抖擞。
-
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。

Meteor including single meteor, and the meteor shower of meteors fire are larger than mung bean of the meteoroid enters the atmosphere will be a visible brightness of the meteor.
流星包括单个流星、火流星和流星雨三种,比绿豆大一点的流星体进入大气层就能形成肉眼可见亮度的流星。

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。
