摘要
海上降雨量的测量由于雨量器受到调查船摇摆的影响,不能保持承雨面积,所以往往会出现很大的误差,该文介绍了一种简单实用的适合在调查船上使用的降雨量测量工具,它是以已有技术为基础,利用陀螺平衡装置维持雨量器的相对平衡,消除了船舶摆动对测量结果的影响,具有较高的实用性及推广价值。
The surface area of the water in rain gauge often change because of the shaking of the research vessel, so the precipitation measurement on the sea always has big error. This article introduced a kind of simple precipitation measurement tool which is adapted to use in the research vessel. It uses peg-top balance equipment to maintain ombrometer＇ s relative balance, so it can eliminate the impact of the research vessel＇s shaking. The test result shows it possesses practicability and value of generalization.
