While evaporation from the oceans is the primary vehicle for driving the surface-to-atmosphere portion of the hydrologic cycle , transpiration is also significant .
虽然海洋蒸发的水蒸气是水循环中地球表面到大气这一渠道的首要组成部分，植物蒸腾所占的部分也颇为惊人。
But so far , he notes , " the fundamental relationship between biomass and transpiration has not been changed . "
