1·Connect a tube FM 5000m altitude to the nostrils, in order to feel the altitude stress.

连接到鼻子的一根高5000米的吸管，感受高原反应。

2·Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes.

风速也随着海拔高度的增加而增加，可能给树木带来严重的压力，这从高海拔地区的变形就可以看出来。

3·ObjectiveTo investigate the effect of simulated high-altitude hypoxia stress on extracellular monoamine and its metabolite levels in hippocampus in rat.

目的探讨模拟高原低氧应激对大鼠海马细胞外液中单胺递质及其代谢产物的影响。
