The results show that infiltration and solidification are effectively promoted by vacuum-adjustable pressureinfiltration process, which also avoids the gas and the inclusion binds.
结果表明，真空变压力浸渗法具有良好的渗流和凝固条件，避免了气体和夹杂物的裹入等问题；

The infiltration process was done successfully on the base of the knowledge of hydraulic and vacuum negative pressure.
