随着体育事业的发展,在体育运动训练和竞赛中,需要现代化的电子仪器。为了解决短跑训练中的精确计时问题,我们教练员和少年运动员,因陋就简地自行设计和制造了一台“自动电子秒表”,它的计时精确度可达10~(-3),而且使用方便。这台表曾在一九七九年全国青少年科技作品展览会上展出,获得壹等奖;并在一九八○年全国体育科研仪器和药物研制成果展览会上展出,经评议,认为操作简单,效果较好,可供训练使用。现把制造的技术介绍如下。
With the development of sports, in modern sports training and competition, modern electronic instruments are needed. In order to solve the problem of precise timing in sprint training, our coaches and young athletes have designed and manufactured an Automatic Electronic Stopwatch, which has a timing accuracy of 10-3, and is easy to use. The table was exhibited at the National Youth Science and Technology Works Exhibition in 1979 and won the First Prize. It was exhibited at the National Exhibition of Sports Scientific Instruments and Drugs in 1980, Simple operation, the effect is better, for training and use. The manufacturing technology is introduced below.
