摘要: 在感光测定中,一般都用图解的方法从感光特性曲线上求出感光度、反差系数和灰雾密度等特性数值.用图解法求得的三个参数有一定的局限性.本文作者采用数学模拟法求出这些参数值.

Abstract: In sensitometry, the sensitivity, contrast coefficient and fog density are generally deduced from characteristic curve graphically.The graphical method of determination of the characteristic parameters has certain limitations.In this paper, the author attempted to obtain these characteristic parameters by using mathematical models.
