Abstract
本实用新型提供一种 正态概率分布演示器。 概率在我们生活和工作中常常会遇到, 但是在教学过程中这种正态分布是无法用语言直观的表达清楚的,这就需要一种演示装置。一种正态概率分布演示器,其组成包括:演示板( 3 ),所述的演示板用螺钉( 5 )固定在墙面上,在所述的演示板上部中间位置装有一个球筒( 2 ),所述的球桶内装有小球,所述的球筒经连接板( 1 )固定在所述的演示板上,在所述的球筒的下面按三角形布置固定 n 层六棱柱( 4 ),所述的相邻两个六棱柱间距相等形成蜂窝结构,在最后一层所述的六棱柱下面安装一组接球管( 6 ),所述的接球管位于相邻两个所述的六棱柱之间,所述的接球管下面有装球盒( 7 )。本实用新型用于教学领域。
The utility model provides a normal probability distribution demonstrator. Probability is often encountered in our life and work, but this normal distribution cannot be clearly expressed in language in the teaching process, which requires a demonstration device. A normal probability distribution demonstrator, which consists of: a demonstration board ( 3 ), the demonstration board is fixed on the wall with screws ( 5 ), and a spherical cylinder ( 2 ), the ball barrel is filled with small balls, the ball barrel is fixed on the demonstration board through the connecting plate ( 1 ), and n layers of hexagonal prisms ( 4 ), the distance between the two adjacent hexagonal prisms is equal to form a honeycomb structure, and a set of ball receiving pipes ( 6 ) are installed under the hexagonal prisms on the last layer, and the ball receiving pipes are located between the adjacent two hexagonal prisms. Between the hexagonal prisms, there is a ball box ( 7 ) below the ball receiving pipe. The utility model is used in the teaching field.
