| Abstract: | The cross sections of the leaves in steam turbines(LST) are changed continuously. This paper discusses the subject for establishing the mathematical model of a complete LST by use of the outline—graths of several cross sections of different parts of the LST with the method of inserting values. So that we can take the advantages of the computer characteristics of swiftness and accuracy to calculate and draw the outline—graphs of LST in any positions. With the result that it can provide an efficient and accurate method for studying and making the patterns of the LST |
