But short - term studies of death from acute exposure on smoggy days have yielded mixed results.
对于因严重暴露在烟雾天气中而造成的死亡情况,短期研究所得的结果含混不清。
The index change rates had corresponding changes with the rising of the simulate-altitude, before acute exposure in hypoxia and just acute exposure in hypoxia.
随着模拟海拔高度的升高,在急性低氧暴露前后,这些指标也随之发生相应递增或递减变化。
The ten cities on this list are the ones with the most acute exposure to problems that could cause large imbalances of water supply and demand.
名单上的十个城市都暴露出可能导致水供需极不平衡的诸多问题。
