gray-scale value

The image reconstruction algorithm based on RBF neural networks uses RBF networks to build the mapping relationship between the capacitance value and the image gray-scale value .

基于RBF神经网络的图像重建方法的实质就是用RBF神经网络建立电容测量值到图像灰度值的映射关系模型。

Gelatin zymography and quantified analytical system were used to detect gray-scale value of straps to observe the expressions of MMP-2 and MMP-9 ;

用明胶酶谱分析和电泳凝胶定量分析系统测定酶解条带的灰度值观察肿瘤组织MMP-2和MMP-9表达水平；
