| 摘 要： | 探索了 X射线照片密度与显微密度计信号电压之间的关系。利用曲线拟合得到了 X射线照片光密度与输出电压关系的公式。经公式计算的密度值与实测密度值之间差别不大 ,其标准估计误差为 0 .0 178,完全可以用计算密度值来代替实测密度值。直接取其显微密度计输出的电信号 ,经公式转换成光学密度值后再进行 X射线照片的各种性能测试 ,避免了部分测试和换算误差 ,克服了过去密度测量的不便 ,提高了效率

| Abstract: | The relation between the optics density of the X ray and the output information voltage of micro densimeter is investigated. A formula which would describe the relation between the optics density and the output information voltage is obtained by a mathematics method. The difference between calculating density values and measuring valuts is small, the standard error of estimate is 0.0178. The measuring value may be replaced by the calculating value from output voltage getted from the micro densimeter. The error is avoided partly and the information data from voltage output of micro densimeter is got directly. It is more convenient and higher efficient. |
