| 8. | The gas field in pemfc means the gas distribution in gas source , gas inlet tube ( scale of m ) , gas - blower , gas manifold ( scale of cm ) , channel ( scale of mm ) , diffusion layer ( scale of um ) , hydrophobic layer and catalyst layer ( scale of nm ) . the aim of changing the scales is to make oxygen reach reaction area as evenly as possible
Pemfc的气场指在气源、进气管(分米级) 、风机、进气箱(厘米级) 、流道(毫米级) 、扩散层(微米级) 、疏水层(亚微米级) 、催化层(纳米级)中的气体分布，每一级尺度的变化是为了气体的进一步均匀化。 |
| 9. | The purified enzyme had a specific activity of 68 . 6 u / mg protein . overproduction of pga was often limited by translocation and / or periplasmic processing steps , subsequently resulted in intracellular accumulation of various types of pga precursors and then formed inclusion bodies in the cytoplasm and / or periplasm

| 10. | The more is diffusion resistance , the less the oxygen quantity is . the even degree going through the diffusion layer and hydrophobic layer depends on relative change of diffusion resistance in crosswise and lengthways . if the diffusion resistance in crosswise is bigger , it will not benefit the oxygen distribution
传输阻力越大，通过扩散层和疏水层氧气的传输量越小，扩散层和疏水层对氧气的均匀化程度取决于其对氧气横向和纵向扩散阻力的相对大小变化，横向扩散阻力大，不利于气体的均匀化。 |
