物质‐场分析是T RIZ中的一种基于功能的重要的问题分析工具．76个标准解则是 T RIZ中一类基于知识的问题解决工具，通过区分所要解决问题的物质‐场模型来确定问题的性质，选择不同的标准解得到技术问题的解决方案．针对目前标准解分类方式选择时易选错及选多个时难抉择的问题，按照物质‐场模型类型及相似性原理，将标准解中解决技术系统性能提高问题的前3类标准解，分为与不完整物质‐场模型、作用不充足物质‐场模型及有有害功能物质‐场模型相对应的3类标准解，归纳了新的标准解解题流程，详细介绍了解题步骤．最后，以多晶体硅破碎过程中易污染的问题为例进一步论证了该分类方式的便利性及可用性．%Su‐Field analysis is an important tool of analysis based on function in TRIZ .Through describing and abstracting the technical problem ,investigators establish the Su‐Field model of this problem .Though ,76 Standard Solutions is a kind of tools of solving problems which is based on knowledge in TRIZ .Designers can obtain the solutions of the technical problem by choosing the different Standard Solutions w hich determine the nature of the problem by distin‐guishing the model of Su‐Field of the problem .Aiming at the problems existing in the current classification method such as easy to choose a w rong solution or difficult to choose from multiple Standard Solutions ,the first three kinds of Standard Solutions which were aimed at improving the performance of the system were reclassified into three types based on the similarity principle .The three types were corresponding to the Su‐Field models which were the incomplete model ,the in‐sufficient model and the harmful model .The solving process and steps were summarized also .Fi‐nally ,the problem of pollution in the process of polycrystalline silicon crushing was taken as an example to further demonstrate the convenience and availability of the former method .
