摘　　要：函数P-集合是P-集合的函数形式,是通过改进P-集合得到的一个具有动态特征、规律(函数)特征的信息规律模型。在函数P-集合中,函数的属性满足数理逻辑中的合取范式。函数逆P-集合是函数P-集合的对偶模型,在函数逆P-集合中,函数的属性满足数理逻辑中的析取范式。这里定义函数P-集合是一类动态信息规律模型,定义函数逆P-集合是另一类动态信息规律模型;在函数P-集合与函数逆P-集合的结构、动态特征与它们的属性范式特征的基础上,给出函数P-集合在信息图像拼接与伪装中的简单应用,以及函数逆P-集合在商品利润的风险估计-识别中的简单应用。函数P-集合、函数逆P-集合是关于动态信息规律应用研究的新理论、新模型。Function P-set is the function form of P-set.It is an information law model with dynamic characteristics and law or function characteristic obtained by improving P-set.In function P-set,the function’s attribute satisfies conjunctive normal form in mathematical logic.Function inverse P-set is the dual model of function P-set,in which the function’s attribute satisfies disjunctive normal form in mathematical logic.Here function P-set is defined as a type of dynamic information law model,while function inverse P-set is defined as another type of dynamic information law model.Based on the structures,characteristics and attribute normal forms of function P-sets and function inverse P-sets,a simple application of function P-set in information image splicing and camouflage and a simple application of function inverse P-set in profit risk estimation-identification were researched.Function P-sets and function inverse P-sets are the new theories and new models for the application research of dynamic information law.
