| 1. | Dust collector - terminology - part 2 : inertial dust collector , porous layer dust collector and wet scrubber 除尘器术语第二部分:惯性式过滤式湿式除尘器术语 |
| 2. | The grain size of the porous layer is about 2nm and the thickness lamellar layer is a few tens of nanometer 由钛合金基体到羟基磷灰石的过渡层是钛的氧化层,厚度大约几个纳米。 |
| 3. | The second layer consists of a honeycomb - like structure . this porous layer achieves moisture permeability and resistance to water penetration 第二层是类蜂窝的孔状结构,以达到透湿和防水功效。 |
| 4. | The layers from substrate to top of the deposited film are ti substrate , buffer layer ( interface between substrate and film ) , porous layer and lamellar layer 研究发现,从钛合金到羟基磷灰石共有四层结构:钛合金基体、钛合金的氧化层、多孔的纳米晶羟基磷灰石和花瓣状的结晶良好的羟基磷灰石。 |
| 5. | Saed ( selected area electron diffraction ) , hrem ( high resolution electron microscopy ) and eds ( energy dispersive spectrum ) experiments confirmed that both the porous layer and lamellar layer are composed of nano - crystalline ha ( hydroxyapatite ) 实验中采用了选区电子衍射、高分辨观察和x - ray能谱等实验手段,分析了羟基磷灰石各层的形态、成分与微结构。 |
| 6. | Through observing the interface of porosity hap sintered at 1050 , the gradient changing of pore size was observed that was like gradient structure of bone . in the compact layer there were a few about 50 y mpores and many about 5um micropores . in the porous layer there were many about 500um pores 致密层存在少量的尺寸为50 m左右的气孔和大量的尺寸为5 m左右的微孔,这是原料中残留有机物烧失以及粉末颗粒烧结不致密形成的;多孔层存在大量的尺寸为500 m左右的大孔,这是柠檬酸造孔剂烧失形成的,在大孔之间存在一些约50 m 、 100 m的气孔。 |
