我厂利用微计算机进行氢氮比控制。在化工企业中H_2/N_2控制是一个比较复杂的课题,由于引入参数多、数据处理程序、参数处理程序,计算服务程序等组合起来在TRS—80机汇编程序有一万多条。同时受TRS—80内存缓冲区容量的限制,这么长的一个程序不能同时在缓冲区内进行汇编,因此,往往采用二个或多个程序。(它们单独分别存盘,使用时,顺序将它们调入内存 I use micro-computer plant hydrogen and nitrogen ratio control. H_2 / N_2 control in chemical industry is a complex subject. Due to the introduction of many parameters, data processing programs, parameter processing programs and calculation service programs, there are more than 10,000 assembly programs in TRS-80. At the same time by the TRS-80 memory buffer capacity constraints, such a long program can not be assembled in the buffer at the same time, therefore, often using two or more programs. (They were separately saved, when used, in order to transfer them to memory
