It is found that the convection heat transfer plays an important part in the bulk above the return flow section and the heat conduction only rises in the bottom region.

研究表明，回流口截面以上区域传热以对流方式为主，底部区域则主要是逐层导热。

The model assumes that forced convection and nucleate boiling coexist in the annular flow regime.

该模型认为环状流区域同时存在强制对流与核态沸腾两种换热方式。

The experiment quantitatively verifies the existence of convection flows of gas induced by the gradient magnetic field, furthermore the convection flow promotes the combustion in diffusion flames.

实验定量地验证了梯度磁场可以诱导气体对流的发生，从而进一步推进扩散火焰燃烧反应。
