在产品可能受到污染的区域，需要制定使用非渗透性的手套，发网，帽子，须套以及限制饮食，喝水，吸烟等的程序。
Procedures for use of impermeable gloves, hairnets, caps, beard covers, etc. and for restrictions on use of food, drinks, tobacco, etc. in areas whereby product contamination could occur.
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.
遗憾的是，当外源(非母体)蛋白质进入婴儿的渗透性肠道时，可能会带来严重的健康问题。
Unfortunately, serious health problems can develop when foreign proteins are allowed into the infant's permeable intestinal tract.
计算结果表明，数值模拟方法能够合理地描述非水相流体的运移过程和污染特征。土体渗透性和污染物残余饱和度是其重要影响因素。
Numerical results show that the contamination characteristics of NAPLs can be reasonably described, which is significantly affected by intrinsic permeability of soils and residual saturation of NAPLs.
