| 摘 要： | 鉴于分子天文学对研究银河系结构、恒星诞生和演化、宇宙化学及宇宙生命等方面有极其重要的意义,近年来国内不仅在这个领域的理论研究有迅速发展,而且积极进行着实测手段的建设.其中,用于谱线观测的射电频谱仪先后确定采用的数种技术方案,均已进行研制并已在实验室调测.然而因种种技术上的考虑,原来并没有打算采用国外已广泛使用的全数字化自相关射电频谱仪.

| Abstract: | We made a prototype digital autocorrelation spectrometer which was used in a successful radio spectral line observation of hydroxyl at 18 cm band ftowards the Halley's Comet and five maser sources. The observation was done cooperatively in March and April 1986 by Peking University, Shanghai Observatory and the 39th Institute of Ministry of Electronics Industry. In China, this observation is the only radio spectral line observation towards the Halley's Comet and the first radio spectral line observation towards molecular clouds. |
