今年5月2日,我国登山队許竞、張俊岩、王富州、邬宗嶽、陈三、索南多吉、成天亮、米馬扎西、多吉、云登等10人,以英雄的气概,征服了拔海8012米的希夏邦馬峰,从而抹掉了地球上最后一个8000米以上高峰的空白点。为了攻克險峰,登山运动員要克服哪些困难,要战胜哪些敌手呢?高山环境有三大特点,这就是稀薄的空气、多变的气候、复杂的地形,它們成为横在通向險峰道路上的勁敌。不言而喻,高度,在高山上是起决定作用的因素,山越高,三个勁敌就越厉害。高山上的空气稀薄到什么程度呢?如果把当时当地的天气形势不考虑进去,只取各高度上气压的平均值,随着空气变稀薄气压下降的
On May 2 this year, 10 Chinese, including the mountaineers Xu Jing, Zhang Junyan, Wang Fuzhou, Zong Zongyue, Chen San, Sonnang Dorje, Cheng Tianliang, Mima Zhaxi, Dorje, and Yun Deng, conquered the Tahai 8012 with heroic spirit. Rice’s Xishabangma Peak thus erased the blank spot on Earth’s last peak of more than 8,000 meters. In order to overcome the dangerous peaks, what difficulties do mountaineers have to overcome and which opponents to overcome? The alpine environment has three major characteristics: thin air, variable climate, and complex terrain. They become a strong force on the road leading to the dangerous peaks. enemy. It is self-evident that altitude is a decisive factor in the mountains. The higher the mountains, the more powerful the three rivals. What is the degree of thin air in the mountains? If the local weather conditions are not taken into account, only the average of the air pressure at each altitude is taken, and the air pressure decreases as the air becomes thinner.
