摘　　要：将一年中可以进行光谱观测的时间相对最多,同时太阳成像质量相对较好的月份作为光谱观测最佳时间。为此我们统计了光谱仪1976年到1987年的观测资料,初步分析得出云台凤凰山太阳光谱最佳观测时间的年分布情况,相对好一些的是9月份,其次是3～4月份。We take the duration as the optimal period during which the more and better observational data are available within one year. After statistical analyzing the related spectral data obtained with the spectrograph from 1976 to 1987, an annual distribution of optimal duration of solar spectral observation at the Phoenix Mountain of Yunnan Observatory is preliminary obtained, the result shows that the optimal durations in a year are September, then, from March to April.
