摘　　要：工程设计中,常常用到压缩因子,但由于需采用迭代计算,造成计算困难。采用PLC的功能块图编程语言,利用反馈变量方便地实现了迭代运算,解决了压缩因子的计算问题。In engineering design, compression factor is often used. However, iterative calculation is needed in acquisition of compression factor, which is often difficult in calculation. By using modular programming language provided in PLC and through feedback variables, iteration can be easily performed, with which the problem in the calculation of compression factor is solved.
