non-porous

The 3-5 μ m non-porous composite microspheres of zirconia and urea-formaldehyde ( UF) resin were used as matrix of HPLAC stationary phase. The diameter and construction of the composite microspheres were judged by scanning electron microscope.

以3－5μm的非多孔二氧化锆与脲醛树脂（UTR）复合物微球用作高效液相亲和色谱固定相的基体，并用扫描电子显微镜检验该基体的结构和粒径。

The phosphoproteins were exchanged by the initial buffer and separated by chromatofocusing in the first dimension. The fractions with pH value between 8.5 and 4.0 were separated by non-porous silica reverse-phase high-performance liquid chromatography.

将磷酸化蛋白用初始缓冲液置换后，进行一维色谱聚焦分离，再将一维收集的pH值在8.5至4.0之间的组分分别进行二维无孔硅胶反相高效液相色谱分离。

When paint is new, it is the most impermeable it will ever be, this means it is a very smooth non-porous, continuous film. This piece of stone has not been properly faced off.

当漆面是新的时，它的渗透性很小，也就是说，它很光滑，没有孔，是一个平滑的面。这块石头的表面还没有很好地弄光滑。
