Porous ceramic materials on the base of strontium zirconate were developed with zirconium dioxide,baddeleyite powder,and granular polysterol.

采二氧化锆、斜锆矿粉、碳酸锶及粒状聚苯乙烯制成了锆酸锶多孔陶瓷材料。

Some people have reported seeing more semivolatile elements in a class of interplanetary dust particles (IDPs) called “chondritic porous” IDPs.

有报告在一类被称作“多孔球粒陨石”的行星尘埃颗粒（IDPs）中见到了较多的半挥发性元素。

A uniform magnetic field acts perpendicular to the porous surface which absorbs the micropolar fluids with a suction velocity varying with time.

均匀磁场垂直作于可以吸收微极流体的多孔表面，吸引速度随着时间而变化。

SEM showed the porous structure of the CTCP and the seeded hPDLCs were well attached to the CTCP with cytoplasmic extensions and lamellipodia.

扫描电镜下可见材料具有良好的多孔网状结构,牙周韧带细胞伸出多个伪足样突起,紧密贴附在材料表面,细胞沿材料的孔隙边缘生长并连接成片。

SEM showed the porous structure of the CTCP and the seeded BMSCs were well attached to the CTCP with cytoplasmic extensions and lamellipodia.

扫描电镜下可见材料呈多孔网状结构，兔骨髓基质细胞紧密贴附在材料表面，细胞可沿材料的孔隙活跃生长。

If you look over the element ratios we measured, you might conclude that our comet particles look more like chondritic porous IDPs than CI chondrite meteorites.

如果你查看我们测定的元素比率，你将得出结论——我们的彗星颗粒看上去更接近多孔球粒陨石IDPs而不是CI球粒陨石。

Adsorbable gases can be separated by porous ceramic membranes under the capillary condensation mechanism of membrane separation, on which prior study was only limited to pure components.

多孔陶瓷膜在毛细管冷凝传质机理的作下能够有效地分离吸附性气体。而毛细管冷凝膜分离传质机理的研究还很不充分,目前,文献报道仅局限于纯组分气体的传质模型研究。

As much as 40% of Hyperion could be porous, according to research led by Dr Peter Thomas of the Center for Radiophysics and Space Research at Cornell University published today in the journal Nature.
