对流

• At the solar surface, convective motions of heated gases jostle the magnetic field line .
  在太阳表面，炽热气体的对流运动把这根磁力线冲来撞去。
• Energy can be released and intense convective activity and maybe thunderstorms are likely to develop .
  能量能够释放，就可能发展强对流活动甚至雷暴。
• High frequency instabilities result in grossly increased convective heat transfer coefficients in the chamber walls .
  高频不稳定性使室壁对流传热系数大大增加。
• Within the rock which forms the highly permeable reservoir convection currents of hot water or steam occur .
  在形成高渗透性热储的岩体内，存在水或蒸汽的对流运动。
• If the temperature gradient becomes too large, then convection will take over the bulk of the energy transport .
  如果温度梯变得太大，那么对流将承担能量传输的大部分。
• The obvious advantage to these is that they respond quickly to changes in flow rate and will indicate these changes .
  明显的优点是它们对流量变化的响应快，并能指示这些变化。
• In cumulus convection ascent rates of several metres a second give a cooling rate of a few degrees per minute .
  在积云中，每秒几米的对流上升速度造成的冷却速率为每分钟几度。
• At the point c, the star develops a convection zone extending from near the surface deep into the extended envelope .
  在C点，星体产生一个对流区，从表面附近向内扩展到广袤的包层。
• Droplet ignition and extinction in practical combustors are strongly influenced by forced convection and turbulence .
  在实际燃烧室中，液滴点火和熄火受到强迫对流和紊流的强烈影响。
• The fluid flow need not be specified in detail to obtain a semi-quantitative assessment of collection characteristics .
  为了得到采取特性的半定量的估价，并不需要对流场作详细的说明。
