yunnan observatory meaning in English
云南天文台
Examples
- Solar radio metric wave radiation events observed using the acoustic - optic spectrograph at the yunnan observatory in march of 1991 with associated optic activity and correspanding evevts are analyzed . some characteristics of the events are obtained in this paper
利用云南天文台声光频谱仪在1991年3月记录到的太阳射电米波辐射事件、光学活动及相关事件作了分析，得到来自6538活动区太阳射电米波事件的一些基本特性。 - We had observed more than ten selected asteroids using 1 - meter telescope in yunnan observatory during 2000 to 2002 . the observational data of seven asteroids had been reduced and analyzed . we have derived their synodic periods and estimated the shape and orientation of rotational axis for one asteroid
为此，我选定了一些直径在125公里左右的小行星进行观测和分析；一方面，测定它们的自转周期，进行“角动量衰减”现象的研究，另一方面，对小行星形状和自转轴指向进行估算，为小行星碰撞演化研究提供更为有利的证据。 - The durations of good imaging within a fixed year are preliminarily obtained by statistical analysis of imaging quality obtained from spectral observations in 1982 with the horizontal spectrograph installed at the yunnan observatory . the results show that in the autumn , september and august , a good image is usually available . for a daytime , there are two time intervals during which the solar image is relatively better than other time , one is in the morning 2 3 hours after the sunrise ; another in the afternoon 3 4 hours before the sunset , and it lasts about 0 . 5 1 . 0 hours for each
通过对云台水平式太阳光谱仪1982年太阳光谱观测中的成像质量情况统计分析，初步得到光谱仪一年中成像质量优良的时间在秋夏9月和8月份；一天内有两次像质优良的时间，上、下午各有一次，分别在日出后2 3小时和日落前3 4小时各有半小时到1小时左右的时间。
