摘要: 我们建立了两台不同类型的固体β射线望远镜系统，并成功地用于实验．本文以这两个望远镜系统为例，阐述了固体β射线探测器的特点，及其在核物理实验研究中所起的重要作用． Two sets of solid β-ray telescopes of different type were bunt and used successfully in experiments.. This paper gives examples of two telescopes to describe the featureof solid β-ray detectors and their important function in experiments of nuclear physics.
