The lay volunteers will stop here, but a team of16 climber-scientists will go on to the south col( just under8,000 metres) and ten will continue to the summit, at an altitude of8,848 metres, where the air pressure is just a third of its sea-level value.

• 业余志愿者将就此止步，而同时一个由16名登山科学家组成的小分队会继续向上攀登直到南隘口（拔略低于8，000米）之后他们中的10人会继续向峰顶前进。
