The conventional evacuating system : combination of oil diffusion pump, booster pump and mechanical rotary pump, has serious faults in the case of pumping the chemically unstable matter. For instance, in the degassing stage of the molecular distillation plant, the gas is composed of air, volatile matter, water vapor and mist of unstable compound. These components are decomposed or polymerized in a evacuating system, and damage the normal opperation of pumps, especially in oil rotary pump. This is caused by less circulation of oil, and moving parts would be damaged.To conquer this difficulty, we tried to select the new pump composion ; diffusion-booster, steam ejector and water jet. This system has not any moving parts, so we can avoid adove difficulty. The performances of these pumps are as follows : Diffusion booster : Pumping speed (800900 l/sec at 10-310-2 mmHg) Critial back pressure (57mmHg) Steam ejector : Pumping speed (20 l/sec at 1 mmHg), Back pressure (40 mmHg) Water jet : Pumping speed (0. 95 l/sec at 5 mmHg), Back pressure (atmosphere).The overall performance shows very satisfactory result, and this system is now under continious operation for over a year.

Recent studies on the Rashba effect on surfaces are reviewed. The Rashba effect refers to the k-dependent spin splitting of valence bands due to spin-orbit coupling in two-dimensional systems under out-of-plane electric field. After the physical mechanism of the Rashba effect is briefed, experimental and theoretical studies since the surface Rashba effect was first demonstrated for Au(111) in 1996 are surveyed with an emphasis placed on the microscopic origin of the giant Rashba spin splitting on surfaces covered with monolayer films of heavier elements. Most recently, giant Rashba spin splitting was realized on the surface of semiconductors, which serves a possibility of spintronic application of the surface Rashba effect.
