1.In this paper,a comprehensive study of flare of 14,July 1980 is presented by using the patrol,of Ha,white light,S2HG observational data obtained at Yunnan observatory,radio data at Beijing observatory and X-ray data from SMM.
本文利用云南天文台耀斑H_α巡视观测、活动区白光照相及速度场资料,结合SMM的X射线资料和北京天文台的射电观测资料,对1980年7月14日日面3B级大耀斑进行了综合研究。
2.Seventeen of the 24 variables in Com. , announced by Archer (1959), were observed in Feb., and Mar. 1984, with an UBV photometer attached to the 91 em reflector at McDonald Observatory and a V colour photometer attached to the 35 cm reflector at Yunnan Observatory. The indentifications of the observed stars are listed in Table 1 and shown in Fig.
在1984年2—3月,用美国McDonald天文台91cm反射镜的UBV测光系统和云南天文台35厘米反射镜V色测光系统,对Archer 1959年在后发座用照相方法发现的24颗变(双)星中的17颗进行了观测研究,全部没有大于0~m.
3.On 4 February 1975, the commune or brigade leading cadres would have obtained information directly or indirectly from six different sources: (1) the general provincial warning relayed to them through city and county committees, (2) in the case of Yingkou County, an evacuation order from the county committee, (3) nearby earthquake observatories, particularly the Shipengyu Observatory, (4) local amateur precursory monitoring groups such as the team of the Haicheng Observatory, (5) neighboring villages and industrial units, and (6) the foreshocks and the damage they were already causing.
1975年2月4日，公社或大队领导干部直接或间接从六个不同的来源获得信息：（1）通过市级与县级革委会传达给他们的总的省一级的警告；（2）在营口的例子中，撤离的命令由县革委会下达；（3）附近的地震观测站，特别如石硼峪地震观测站的情况；（4）地方的业余前兆检测工作组，如海城地震观测站（“群测点”）；（5）附近的村庄与企业，与（6）前震以及已经造成的损失。
4.The experimental results showed the time comparison precision was about ±8ns and the time comparison accuracy was about±100ns. At the same time we established the link between Hong Jiao ground station and Shaanxi Observatory by the Loran— C/9970 and BPL time signal transmitted by Shaanxi Observatory.
在试验期间,同时接收Loran—C西北太平洋链的信号以及陕西天文台的BPL长波授时信号,并在上海与陕西之间进行了搬钟验证。 试验结果表明,利用卫星进行时间比对的平均精度为±8ns(1σ),时间比对的准确度优于100ns。
5.Starting from the basic theory and method of CRS,the actual developmental status of CRS is introduced in particular. It indicates that the formula of small angle rotary method is wrong,which is adopted by Crimean Observatory of Ukraine,Shanghai Observatory and IERS in calculating reference frame of extra-galactic radio star sources,and corrects this error.
本文从天球参考系的基本理论和方法出发 ,详细地介绍了天球参考系目前的发展状况 ,指出乌克兰里克米亚天文台、上海天文台和IERS在计算河外射电源参考架时采用的小角旋转法公式是错误的 ,并进行了改正
6.This is the second report on the topic whether seismomagnetic signals exist in the Sq variations of three magnetic components before great earthquakes. A great earthquake of M S7 1 occurred on October 19, 1996 near the Kanoya magnetic observatory in Miyazaki, Kyushu, Japan. The distance between the epicenter and the Kanoya observatory is about 90 km.
1996年 10月 19日日本九州宫崎 (Miyazaki)发生 7 1级地震 ,震中距鹿屋地磁台约 90km。
7.Complex type III-moving IV solar radio burst on Sep. 23, 1998 observed with radio spectrometers (1 - 2 GHz and 2.6 - 3.8 GHz) at Beijing Astronomical Observatory (BAO) is analyzed preliminarily, combining with the data obtained from the SSRT (5.7 GHz ) in Russia and radio spectrometer in Germany. These study fields of electron acceleration and magnetic structures in the corona are expanded.
利用北京天文台1998.09.23日1—2 GHz和2.6-3.8 GHz频谱仪观测到的一个III—IV型复杂大爆发,结合俄罗斯SSRT和德国分米-米波动态频谱仪的观测资料,进行了初步的比对分析,拓展了关于日冕电子加速和日冕磁结构方面的一些研究内容.
8.High signal-to-noise spectral observations were taken in red region by use of the coude Reticon attached to the 2.1 m reflector at McDonald Observatory ia November and December, 1984. Following the former studying [ 4 ] , we analyse the rotation for 37 stars from 31 RS CVn binary star systems.
我们用美国McDonald天文台2.1米反光镜Coude Reticon观测,对31个RS CVn型双星系统的37颗子星的自转进行了测量。
