A Programming Calculation Way about Bubble Point

In design calculation of petrochemistry industry, bubble point calculation has an extensive application, it is very important. In the course of calculating bubble point by bubble point equation, it is very difficult to select bubble point temperature or pressure, but it is easy to bring radiation phenomenon in calculation. Therefore, calculation result could not be achieved. In the paper, a programming calculation way about bubble point is bring forward, which avoids above problems. Moreover, the program, which is adjusted by the temperature or pressure and applied in calculating bubble point, can be applied extensively in calculating no linearity humdrum continuity function.
