| Abstract: | It is very important to study the relation between the metal's saturated vapor pressure and temperature in the vacuum evaporating deposition technology. For several metals, such as aurum, argentum, aluminium and gallium, their p T curves are plotted in this paper by B spline method. The basic principle and algorithm implementation are described, and some key techniques and features are discussed. Further more, several improved ways about algorithm and software environment are proposed too. The relative software is developed by C language, and its function and running result are shown, which it is successfully applied control temperature and pressure technology conditions in the vacuum evaporating deposition industry. |
