摘　　要：本文提供了一个精确设计麦克斯韦速率分布演示仪的理论方法,可以精确计算出伽尔顿模板底部的滑行曲线.以铊原子蒸汽的麦克斯韦速率分布为实例设计演示仪,给出滑行曲线的解析式.A theoretical method is proposed to design the demonstrator of the Maxwell speed distribution precisely. The sliding curve set on the bottom of the Gardon board may be calculated exactly. As an example, we design the demonstrator that shows the Maxwell speed distribution of Tl vapor and present the analytical formula for the sliding curve.
