摘　　要：介绍了余误差函数的定义,激光打印机的定影过程和与定影过程相对应的扩散模型,阐述了余误差函数的数值计算对设计激光打印机定影过程的重要性,并指出了已有文献给出的余误差函数的数值计算方法的局限性,在此基础上,分析了3种可行的数值计算方法:查表法、近似计算法和利用Excel中的工程函数直接计算法,并对每种方法进行了比较,最后确定了一种有效可行而且简洁的数值计算方法,解决了激光打印机定影中的实际问题,提高了工程设计效率。The definition of error function complement, the fixation process of laser printer and the corresponding defusion model are introduced. The importance of numerical solution to error function complement for designing the fixation process in laser printer is introduced. The limitation of the numerical methods for error function complement in the literature is pointed out. Based on the present methods, another three possible numerical solutions are proposed, including mathematical manual, approximate method, and direct method from the engineering function in microsoft excel software. By comparison, it shows that using the engineering function in excel software is the best and most convenient choice. In the fixation process of laser printer, the method is useful and efficient.
