Just think of yourself as Sir Edmund Hillary leaving base camp.

登顶珠峰第一人把自己想象成埃德蒙·希拉里爵士从营地里出发就好了。

The height variation of the ME snow summit is, according to the GPS measurement in 1992 and 2005, that 25 cm has been descending in the past 13 years, i. e. with the descending rate of 1.8 cm/ a.

根据1992年和2005年的GPS测量，珠峰峰顶雪面高程的变化在13a间约下降25cm，平均年下降率为1.8cm。

The results show that crustal elements such as Al, Ca, Si, K, Fe are the main composition of atmospheric aerosols over mount Qomolangma region and account for more than 82% of the total elemental concentration.

初步分析结果表明，珠峰地区大气气溶胶以Al、Ca、Si、K、Fe等地壳元素为主，地壳元素占总元素浓度的82%以上。

In addition, several previously unnamed grasshopper species were collected during the famously ill-fated 1924 British Everest expedition and are now on display in the British Natural History Museum.

并且，在1924年的那次以失败告终的英国珠峰探险之中，探险者就采集到了跳蛛样本，这些样本现在被陈列在英国自然历史博物馆（British Natural History Museum）之中。

When memories of this year's trauma subside, mountain enthusiasts will return to Everest with the same zeal as before, according to Jiban Ghimire, the managing director of Shangri-La Nepal Trek, a company in Katmandu that provides support to mountaineering teams.

位于加德满都的香格里拉尼泊尔徒步公司（Shangri-La Nepal Trek）为登山队提供支持。公司执行董事吉班·吉米雷（Jiban Ghimire）表示，当关于今年的创痛的记忆退却之时，登山迷们还是会带着同样的热情重返珠峰。
