标准范围

该方法的原理是按照规定对样品进行曝光和处理，从合成图像中获得密度测量值，以生成感光曲线，从中获取值并用于确定ISO速度和ISO范围。该方法适用于泡状缩微胶片，其主要光谱灵敏度在350 nm至450 nm范围内，用于从正片原稿生成负片图像和从负片原稿生成正片图像。

The principle of the method specified is exposing and processing samples as specified, obtaining density measurements from the resultant images to produce a sensitometric curve from which values are taken and used to determine ISO speed and ISO range. The method applies to vesicular microfilms which have their principal spectral sensitivity in the region of 350 nm to 450 nm and are used to produce negative-appearing images from positive originals and positive-appearing images from negative originals.
