X射线管辐射场强度阴极侧高于阳极侧。当X射线透过钢板后,底片的黑度阳极侧高于阴极侧。本文通过试验发现了这一现象,并试图定性地解释这一现象。
The X-ray tube field intensity is higher on the cathode side than on the anode side. When the X-ray transmission through the steel plate, the darkness of the negative side of the negative side of the film. This article found through experimentation this phenomenon, and try to explain this phenomenon qualitatively.
