本文简要介绍和分析了确定水和水蒸汽参数的计算机程序的常用方法,指出在汽轮机装置热计算中拟采用专用子程序的形式。介绍了综合应用已有公式用FORTRAN语言编制的适用于舰用汽轮机装置热计算的若干实用子程序,并有编制两个专用子程序的方法及其应用的举例。 This paper presents a brief introduction to and analysis of common methods for computer programs that determine water and steam parameters. It is pointed out that specialized subroutines are intended to be used in thermal calculations of turbine installations. A number of practical subroutines for the thermal calculation of marine steam turbine installations, which have been formulated using the FORTRAN language in combination, have been introduced. Examples of methods and their applications for the preparation of two dedicated subroutines are introduced.
