It read: 2015 Everest Expedition fully underway.

照片旁写的是：2015珠峰探险全面展开。

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。

The quake's epicentre was close to Everest Base Camp, which was evacuated after an avalanche triggered by the April 25 quake killed 18 climbers.

此次地震的震中接近珠峰大本营（Everest Base Camp）。在4月25日发生的地震引发的雪崩导致18名登山人员丧生后，珠峰大本营的人员已经撤离。

Anyone who climbed Mount Everest and survives is lucky.

挑战珠峰能够存活是一种运气。

But China and Nepal have had a long-running disagreement over the height.

但中国和尼泊尔在珠峰的高度认定上却存在长时间的争论。

Two Sherpas, Apa Sherpa and Phurba Tashi, hold the joint record for most Everest ascents.

两个夏尔巴人——阿帕·夏尔巴（Apa Sherpa）和普巴·塔西（Phurba Tashi）——共同保持着登顶珠峰次数最多的纪录。

The joint announcement of the new peak height is of great significance in carrying forward the undertakings to the future and showcasing the high level of the continuous development of China-Nepal relations.

今天我和你共同宣布珠峰最新高程具有承前启后的时代意义，也充分体现了中尼关系持续发展的高水平。
