本文介绍了在VIZ型无线电探空仪的湿度管道中安装振丝式传感器对过冷液态水进行实验室测量的方法。振丝式传感器的振动频率随其上收集的冰的质量而变化。过冷云是通过将蒸汽注入一个寒冷的房间而产生的。测量是使用旋转臂产生的速度与上升的无线电探空气球相当。从振动线测量发现的过冷液态水浓度进行了比较与基于高速旋转棒的标准测量。基于振动频率的测量和比较与冰的重量收集的旋转棒，它的结论是，振动线系统测量过冷液态水的浓度与控制测量。在这些近似稳态条件下，在2分钟的时间间隔内发现的频率变化率（与控制测量相对应）。
Abstract Laboratory measurements of supercooled liquid water are made by a vibrating-wire sensor whose frequency of vibration varies according to the mass of ice collected on it. The vibrating-wire system is designed to be placed in the humidity duct of VIZ type radiosondes. Supercoolod clouds were generated by injecting steam into a cold room. Measurements were made using a rotating arm to generate velocities comparable to rising radiosonde balloons. Supercooled liquid water concentrations found from the vibrating-wire measurements were compared with a standard measurement based upon a high speed rotating rod. Based upon the vibrating frequency measurements and comparisons with the ice weights collected by the rotating rod, it is concluded that the vibrating-wire system measures supercooled liquid water concentration in agreement with a control measurement. The rate of frequency change found in these approximately steady-state conditions over a 2-minute interval (to correspond with the control measuremen...
