| 9. | The texture and colours of ice can also vary . the lower the air content , the more the colour changes from white to blue - just like your fingers 冰的结构和颜色也千变万化。冰中的空气含量越少,其颜色变化就越多。 |
| 10. | An analytical model for the forced condensation of steam in the presence of noncondensable gases was proposed based on the mass , momentum and energy conservation equations of condensing mixture flow , involving the analogy between heat and mass transfer in the gas / liquid interface 总之,蒸汽流量、空气含量和系统压力是影响蒸气冷凝的重要因素。相似的基础上,建立了竖直管内蒸气强迫对流冷凝的一维分析模型。 |
