查询词典 sensitometry

Thus,in routine tests,it is reasonable and practical to use specific visible light instead of the X-ray beam as the illuminant for sensitometry.

因此 ，在日常的检测工作中，采用特定的可见光代替X射线作为感光测定时曝光的施照光，是实际而合理的方法。

Sensitometry: Study of the response of photographic emulsions to light.

感光测定：研究摄影乳剂对光的反应。

Photographic sensitometry, determination of optical density; geometric conditions for reflection density
