| Abstract: | It is shown that the full pressure of each point detected is equal in
the vaccum apartment, and it is recognized that the flow field inory
vaccum apartment is a potential one. According to the aerodynamic theory,
theoretical flow field in the vaccum is the one shown by the equal potential
lines calculated with finite element method and FORTRAN program. |

| Keywords: | vaccum apartment potential flow field |
