汽轮机作为动力机械广泛应用于电力、化工等多个行业，汽轮机故障诊断也愈来愈受到人们的重视。气路通流面积作为汽轮机故障诊断的重点，能够通过弗留格尔公式计算得到。由于该公式假设条件是汽轮机有无穷级，故在实际应用中该公式的精度不高。笔者对弗留格尔公式进行改进并将其应用于汽轮机通流部分故障诊断，以此来提高诊断精度。

The Stream Turbine ,as power machinery ,has been widely used in electric power industry and chemical industry in recent years .Correspondingly ,the fault diagnosis of Stream Turbine becomes more and more attractive and stressed .The common fault diagnosis method is focused on flow area ,which can be calculated by the Friu Geer formula .Because the formula assumes that stream turbine has infinite stages ,the accuracy is not high .By improving the Friu Geer formula ,it can achieve higher accuracy in the fault diagnosis of stream turbines .
