| 1. | The first is the channel theory of permeability .
第一个是透过度的通道理论。
|
| 2. | It is evident that the permeability is not a constant .
显然磁导率不是常数。
|
| 3. | The permeability of a soil is important for calculations of underground flow .
土的渗透性对于地下液流的计算很为重要。
|
| 4. | Histamine causes vasoconstriction and increased permeability of small venules .
组织胺能引起血管收缩，并增强小静脉的透性。
|
| 5. | When there is an interface, there is a question of permeability of the fluid moving through it .
只要有一个交界面存在，就有流过该交界面的液体渗透问题。
|
| 6. | It seems likely that the drug resistance is caused by permeability changes rather than enzyme deficiency .
抗药性似乎是由渗透性改变而不是酶缺损而引起的。
|
| 7. | Local substances released by injury produce vasodilatation and increased small vessel permeability .
电损伤释放的局部物质引起血管扩张和增加小血管的通透性。
|
| 8. | Permeability remains an elusive parameter that is not directly measurable by geophysical methods .
渗透率则是一个不能用地球物理学方法直接测出的、捉摸不定的参数。
|
| 9. | A natural escape of hot fluids from the steam reservoir should be prevented by cap rocks with low permeability .
只要存在通透性能低的盖层，蒸气储放热流体就不会自行外逸。
|
| 10. | Fortunately, iron or iron alloys are available which combine high permeability with small hysteresis loss .
幸而，目下已有兼备高磁导率和低磁导率损耗的铁和铁合金，可资利用。
