在X线片的暗室处理中,由于沿用的安全照明亮度非常低,造成操作不便,效率低,工作人员还容易产生疲劳感。为此,很多科研人员为提高安全照明的亮度进行了大量的研究工作,例如在X线片感光乳剂中加入各种减感剂,在胶片显影前进行减感前浴处理等。这些方法都因为有一定的缺点,所以实用价值不大。近年来,由于X线片自动冲洗机的实用化,国外对这一课题的研究已不感兴趣。但是,根据我国的国情,离x线片冲洗自动化尚有一段距离,因此作者认为目前对本课题的研究仍有其一定韵实用意义。
In the X-ray darkroom treatment, due to the use of security lighting brightness is very low, resulting in inconvenient operation, low efficiency, the staff is also prone to fatigue. To this end, many researchers to improve the brightness of safety lighting carried out a lot of research work, such as the X-ray emulsion added a variety of desensitization agent, before the film development for pre-sensory bath treatment. Because of these methods have some shortcomings, so practical value is not. In recent years, due to the practical application of X-ray film automatic washing machine, foreign countries have no interest in the research of this topic. However, according to China’s national conditions, there is still a long way to go before automation of x-ray film processing. Therefore, the author believes that there is still some practical significance for the research of this subject at present.
