自报雨警铃(或谓降水警铃、降雨止雨警铃、报雨信号器等)创制以来,全国各水文机关先后设计了许多式样,目前在各站已确为盛行并仍在继续发展试制中。为了解决夜间降雨观测的困难,消除降雨起讫不明符号,提高雨量观测成果,报雨警铃的创制是有价值的,是值得很好地总结推广的。据此目的,我站曾根据目前几种比较流行的报雨式样,分别进行试验,将所得经验总结如下,供各兄弟水文站参考。
Since the invention of rain alarm bell (or precipitation alarm bell, rain alarm rain bell, rain signal device, etc.) since the creation of the national hydrological authorities has designed many styles, at each station has indeed become prevalent and continues to develop Trial production. In order to solve the difficulty of night-time rainfall observation, eliminate the unknown sign of rainstorm, and improve the result of rainfall observation, the creation of rainstorm alarm is valuable and worthy of well summarizing and popularizing. According to this purpose, we have carried out experiments separately on the basis of the more prevalent types of rainstorms at present. The experiences we have summarized below are for the reference of the brothers and hydrological stations.
