为了解决生产检验工作中手工绘制回火脆性转变温度曲线存在的诸多问题,根据试验数据不同的离散度,建立了三种类型的数学模型,并应用Visual Basic语言编制回火脆性转变温度曲线图程序。经过生产检验所得到的数据的验证,证明该程序是完全符合试验数据的变化规律,具有一定的科学性和实用性。

According to the different discrete degree of the testing data,three types of mathematical model are established. Then these temper brittleness transition temperature curve chart are programed by the models by VB language. The program can resolve many problems which happened by manual plotting curve chart in the produce examining. The program which has been verified by the data gained in the produce examining conforms the objective rule of the testing data and is precisly scientific and utility.
