摘要：
The pumping characteristic of water vapor on boron and lanthanum hexaboride films formed with an electron beam evaporator have been investigated in high vacuum between 10(-4) and 10(-3) Pa. The measured initial maximum pumping speeds of water for the fresh B or LaB6 films with a deposition amount from 2.3 x 10(21) to 6.7 x 10(21) molecules/m2 separately formed on a substrate are 3.2-4.9 m 3/SM 2, and the saturation values of adsorbed water on these films are 2.1 x 10(20)-1.3 x 10(21) H2O molecules/m2.
