摘要
用实验方法研究了图形离散度与图形信号传信绩效的关系。实验的自变量为图形的离散度参数，取值范围为０．３－０．７，应变量为通道容量，实验的刺激信号为２５个矩形组合图形。结果表明，矩形组合图形的离散度与传信绩效的关系为一种非线性函数关系，离散度适中（０．５左右）的图形信号传信绩效较高。增大增减小图形的离散度均不利于信息的有效传递。
Abstract An experiment was conducted to investigate the relationship between the dispersion of figures and information transfer efficiency. The experimentalvariable was the dispersion of figures, which ranged from 0.3 to 0.7. The dependent variable was the channel capacity. The results showed the relationship between the dispersion of matric figures and the information trasfer efficiency approched to a nonlinear function.The figures with middle dispersion (about 0.5)had high information transfer efficiency.Either increasing or decreasing the dispersion caused the decrease of efficiency.
