An accurate replica of the source should be provided for practice in handling and for making accurate measurements of source-detector distances . 为了练习操作，为了精确地测量源到探测器的距离，应当备有源的精确的复制品。
The limitations of this scheme became quite apparent with the introduction of detectors such as the plumbicon, image orthicon and vidicon . 这个方法的局限性在引进诸如氧化铅光导管摄像管，超正析象和光导摄像管之类的探测器之后变得很明显。
