1) local free convection
局地自由对流
1.
In this paper Monin-Obukhov similarity functions,embeded with local free convection,of surface layer in unstable atmosphere are obtained by using dimensional analysis,in view of turbulent generation and development, based on determinative factors of turbulent transport---turbulent dynamic energy and mixing length.
本文从湍流产生和发展的本质出发，以湍流动能和湍流混合长为湍流输送的决定因子，用因次分析的方法得到了一套可包括局地自由对流在内的不稳定大气近地层Monin－Obukhov相似性函数。
2) free convection
自由对流
1.
The problem considered is that of the free convection boundary layer on a horizontal elliptic cylinder whose temperature is suddenly increased.
就水平放置的椭圆柱体温度骤然升高所产生的自由对流问题 ,选取椭圆坐标系 ,建立了与时间相关的边界层方程 ,应用傅里叶级数简化方程组的边界条件 ,并以此逼近得到精确解。
2.
Under certain conditions, the vertical density difference may induce free convection of the fluids.
自由对流是一种由于流体的密度变化而产生的流体的运动。
3) local convection
局地对流
1.
The results suggest that the local torrential rain occurred on 13 July 2007 can be attributed to the uplifting of southeast streams at lower levels forced by mountains,and the local convection occurred on 10 July 2007 was triggered by an ABL convergence line.
利用常规气象资料、雷达、风廓线和地面自动站资料,分析2007年7月两次局地对流天气过程发现,7月13日的局地短时暴雨是由低层东南风遇山脉抬升后产生的;7月10日的局地对流是由边界层辐合线触发形成的。
4) free thermal convection
自由热对流
1.
The underlying abnormal mantle heat gave rise to the free thermal convection, which in turn caused the heat to be lossed.
笔者借以热力学的自由热对流原理来加以论述:攀西巨厚的火山岩体在下覆异常地幔热作用下,发生自由热对流,引起热量散失,使地壳沉降与隆起不均衡,生成地堑地垒的格局。
5) laminar free convection
层流自由对流
6) free convection
自由对流，自然对流
