中文摘要: 回答器是高空探测仪器的组成部分。长期以来我国一直使用以电子管为主要元器件的回答器，目前在回答器的关键元器件中，晶体管替代电子管已由趋势变为现实。中国气象局从1997年起在全国范围内推广使用晶体管回答器。作者从原理、性能测试以及正确使用方法等方面对晶体管回答器作了介绍。
中文关键词: 晶体管回答器，原理，使用
Abstract:The transmitter is one of important upper-air sounding instruments.A volume tube as a key element of the transmitter has been used for a long period,it has become a reality that the volume tube is replaced by a transistor in the transmitter.The transistor transmitter Type GPZ5-3 has been used in all upper-air sounding stations since the beginning of 1997.The information of this instrument including its principle,specifications test and the right operation was described.
