孔洞

Then, cellular PP films were modified by extraction, oxidation and fluorination in a hydrofluoric acid solution.

红外分析和断面的X射线能谱分析表明，经过相继的化学处理(表面小分子萃取、氧化处理和氢氟酸处理)后，PP孔洞薄膜生成了具有一定(来源：A59BCc747论文网www.abclunwen.com)深度的氟化层。

Inspect staircase handrail, platform, footway and covers on trench openings for right function.

检查楼梯栏杆、平台、走梯及地沟孔洞的盖板是否完整，厂房和应急事故照明是否良好。

And when the plant pro recommends those funny-looking pots with all the little holes in them, go for it.

当植物亲建议那些搞笑的前瞻性盆与所有的小孔洞，去为它。

The thermal curing mechanism and property of low dielectric films based PPSQ were studied by FTIR, Gaussian curve fitting and Spectroscopic Ellipsometry.

FESEM测试表明PPSQ在485℃之前能得到平整致密的薄膜；在485～525℃由于苯基的氧化分解有致孔的效果，孔洞结构为圆孔；在525℃之后圆孔将变成连孔，薄膜在局部将变得致密。

Formation of voids and hillocks at the cathode and anode, respectively, has been observed.

其结果，在负极端及正极端界面上，分别生成孔洞和凸起物。

Before degradation: limpid stereo reticular structure of PLGA; One week after degradation: PLGA was corroded and the reticular structure was decreased; Three weeks after degradation: airspace was gradually disappeared and the reticular structure was further decreased; Five weeks after degradation: airspace and the reticular structure were completely damaged, which was in an indefinite form.

降解前PLGA(丙交酯和乙交酯的摩尔比为90∶10)支架材料呈清晰的三维立体网状空隙结构；降解1周后，材料表面受侵蚀，网状结构减少，孔洞局灶性连接呈片状；3周时材料表面受侵蚀现象加重，空隙逐渐消失，网状结构进一步减少，聚合物融合呈大片状；5周后材料空隙、网状结构完全消失，呈不定型均质状。

By employing the 2D discrete dislocation dynamic modeling, the stress distribution in the vicinity of an isolate circular particle embedded in an infinite FCC matrix is investigated, and the void nucleation mechanism is discussed.

基于二维离散位错动力学模拟方法，研究了无限大FCC单晶体内微夹杂周围的应力场分布，讨论了夹杂处孔洞形核的可能机制。

Results CPC-30%vol%PLGA had the best mechanical capability,σ=40.5 Mpa,Ε=13.8 Gpa;Intercommunicative holes which size was among 100 μm～300 μm was observed in...

结果CPC-30%vol%PLGA力学性能最好，抗压强度40.5MPa，弹性模量13.8Gpa；模拟体液下降解6周材料形成100～300μm相互连通孔隙；骨髓间充质干细胞在支架材料表面生长良好，并通过降解产生的孔洞内材料深部长入。

The most perfect models prebiological organisms are fi brous kerite crystals,crystallized in pegmatite voids according to the VLS mecha nism,their shape,structure and composition are very close to those of living org anisms.

前生物有机体的理想模型是纤维状黄绿蛭石，它是按照VLS机制在伟晶岩的孔洞中结晶出来的，其形态、结构和成分与生物有机体十分相似。

Lastly, it needs to be covered with alayer of non-porous, non-cracked rock to provide a leakproof cap.

最后，还需要在外面包上一层没有孔洞和缝隙的岩石来作为防漏罩。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
