Range Finder and Calculating Board for Jump-Ski

跳跃滑测距器和绘算板是滑水运动跳跃滑项目测算运动员跳跃成绩的裁判和训练的必备专用器材。本文着重介绍了测距器和绘算板的构造原理,跳跃成绩的计算,仪器的使用方法和如何确定观测器的观测位置等。本文所列跳距计算式,如配以电算机程序,可同时打印运动员号码,跳距,上台角度,起跳及着水时间,并排出名次。本套装置自1981年迄今已作到Ⅱ型,经使用,达到国内、国际竞赛要求。

The Jump-Ski Range Finder and Calculating Board is a useful instrument for measuring results in water-skiing contests. This paper provides an explanation about the principles of its design, the measuring formula and the methods of using it.By putting the Jumping Range formula into a computer,we can simultaneously produce some other data such as the skier's number, the length of a jump, the entering angle, the commencing and finishing time of each jump, and even the placing of each competitor.This instrument was first produced in 1981 and by now a Type II version has been developed. Over the years it has been used in domestic and international competitions with satisfactory results.
