地面条件 meaning in English
surface condition
Examples
- Comparison of structures between crystals of barheaded goose hemoglobin grown in space and earth
空间和地面条件下斑头雁血红蛋白晶体结构的比较研究 - This exhibit creates an environment simulating how astronauts walk on the moon , letting visitors experience the feeling of walking under conditions of weightlessness or little weight , and allowing audience members , especially young people and teenagers , to acquire an interest in astronautical activities
展品为观众创造在地面条件下模拟宇航员在月球表面行走的环境，使观众体验微重力条件下行走时的飘浮感觉，培养观众、特别是青少年对航天活动的兴趣。 - Wavelengths or scales of surface heterogeneity are less than 20km . simulation results show that cbls do reach a quasi - stationary state correspondent to specified surfaces , after a long enough evolution . in this transition process and after that , horizontal statistics , i . e . mean potential temperature and vertical heat - flux , show profiles little differences to those over homogeneous flat surface . main effect of surface heterogeneity is to increase kinetic energy in cbl and the increase concentrates in the direction of surface heterogeneity . the time of cbl spent to reach its first peak of mean kinetic energy ,
模拟结果表明，在充分长的时间后，边界层达到一种适合于地面条件的准定常态。这种准定常态和向其过渡的过程中，水平平均的边界层廓线性质，如平均位温廓线垂直热通量廓线等几乎与平坦均匀地面的结果相同，或差异极小。地面非均匀性的主要作用是使边界层动能增大，并以地面非均匀性变化方向的动能增加为主。
