摘　　要：本文从潜影形成和热显影过程两方面综述了提高光敏热成像(PTG)材料感光性能所采取的方法和所取得的成果.在潜影形成方面,主要阐述了增加光吸收效率、提高潜影形成效率和降低最小潜影中心的原子数来提高感光性能,而在促进热显影方面,分析了显影剂、有机银盐、显影促进剂、pH值、pAg值等对感光性能的影响,并提出了可能存在的其他因素.In this paper, the methods and the results in the researches for improving photographic properties were reviewed based on both the formation of latent image and the process of heat development. In the former, improving photographic properties by increasing efficiency of light absorbance, improving efficiency of forming latent image and ：reducing atoms of center of smallest latent image were summarized, and in the latter, the influence of developer, organic silver salt, development advancers, pH, and pAg on the photographic properties were analyzed. Some other possible factors were proposed.
