摘要
简述落球法测定重力加速度等实验中 ,采用自制激光光电计时器 ,提高了测量时间的准确度 ,该计时器具有定位准、抗干扰能力强等优点。
A new type of laser photoelectric calculagraph has beendesigned and constructed.Using this home-made calculagraph to measure the acceleration of gravity in the free-fall experiments,we have a much better accuracy than before.The results show such photoelectric calculagraph has the advom tages of accurate orientation and strong interference rejection etc.
