物料内部的水份(溶剂)不断的向表面渗透、蒸发、排出、三个过程不断进行，物料在很短时间内达到干燥目的。
Water (solvent) inside the material is permeated, evaporated and discharged from the surface. The said three processes happen constantly and the materials will be dried in a short period.
结果显示，表面渗透探伤法能准确确定连轧坯和轧后钢板表面缺陷的位置。与酸浸法相比，表面渗透法更加直观、准确。
The results show that the defaults places can be exactly determined by penetrant method which is more visual and accurate than acid leaching method.
因为这种瓷料是陶瓷质地的，看起来像玻璃，与老式的物料不一样，其表面是光滑而且具有非渗透性，咖啡，茶叶红酒或是抽烟等都不会在其表面形成斑点。
Since porcelain is ceramic, and therefore glass-like, its surface is smooth and impervious and unlike older bonding materials, it will not be stained coffee, tea, red wine or cigarette smoking.
