【摘要】 用尖端导线作感应元件,用调频—调幅体制传递讯息,制成了雷雨云中的电场探空仪。频率调制器由一只2П1П管组成,另一只2П1П管组成发射频率为85兆赫的发射机。地面接收设备采用了一定的抗干扰电路,能消除非当顶闪电引起的干扰,使用该仪器进行了五次探测(结果见图9),并对深测结果作了初步分析。更多还原

【Abstract】 The electric-field-radiosonde for thunderclouds is made. A long wire with points at both ends is employed as its inductor and a FM-AM telemetering system is used. The FM-AM system consists of two vaccum tubes 2П1П. One is used for frequency modulator and another for transmitter. The transmitting frequency is about 85 MHZ. An anti-interference circuit is employed in the receiving equipments, thus the interference caused by non-overhead lightning can be removed. The results of five soundings obtained in thunderclouds are given and analy2ed primarily.更多还原
