水准面 [测] level plane
[测] water level
[测] level surface
- 在较低地水准面地区,大雪帮助农民保持土壤温度,因此在严寒中挽救了种子。
Snow aids farmers by keep heat in the lower ground levels, thereby saving the seeds from freezing. - 本次制作的地球水准面模型在绘制地球地貌时也将会被用来参考。
The geoid is also used as a reference surface from which to map the topographical features on the planet. - 地水准面臭氧(来自交通和生物量燃烧),碳黑(来自摩托车)和甲烷(来自农业,牛和木材燃烧)也起到一定的作用。
Ground-level ozone (from transport and biomass burning), black carbon (from motor vehicles) and methane production (from agriculture, cattle and wood burning) also play roles.
