The turkmen mountains are relatively high, but it is hard to imagine the palace remaining frozen without some sort of technical help
土庫曼山的海拔相對來說比較高，但是如果沒有一定的技術支持，很難想象宮殿能夠一直保持冰凍的狀態。The results demonstrate that the upper limit of permafrost in this area had declined from 1970s to the middle phase of 1990, and permafrost has appeared degenerate tendecy, but since middle 1990s, permafrost have a stable state ; ground temperature of roadbed near the earth surface is higher than that of the natural ground, thawing time of roadbed near the earth surface is longer than that of the natural ground, the heat income within the permafrost is greater than the heat release from the permafrost during anannual period, the heat accumulation within the permafrost is temporarily appeared as temperature rising, but with the heat accumulation within permafrost growing up year by year, permafrost temperature will become higher gradually, and strong thawing of permafrost could be happened in the region
結果表明：風火山地區從20世紀70年代到90年代中期凍土上限下降，凍土出現退化現象，從90年代至今凍土趨于穩定；路基近地表地溫明顯高於對應天然地表下的地溫，路基近地表經歷的融化期長于對應天然地表，進入多年凍土區的熱收支也呈現出吸熱明顯大於放熱的周期性變化，進入多年凍土的熱積累暫時以增高地溫耗熱為主，但隨著凍土吸熱量的逐年積累、凍土溫度的不斷升高，本區凍土可能發生強烈融化。The research work about durability of high - performance self - compacting micro - expansive concrete show that the micro - expansive function and micro - bubble producing function of mineral admixture h can improve the impermeability, frost - resistance ability and sulfate eroding resistance ability etc of self - compacting concrete
研究了免振搗微膨脹高性能混凝土的各項耐久性能，結果表明：山于新型礦物添加劑h的微膨脹功能和微量發氣功能，研製成功的免振搗微膨脹高性能混凝土具有優良的抗滲性、抗凍性、抗硫酸鹽侵蝕等耐久性能。We are already seeing changes in rainfall ; an increase in the frequency and severity of extreme weather events ; melting sea ice and permafrost ; retreating glaciers
氣溫不斷升高，降水量開始改變，極度惡劣的天氣情況愈加頻繁，破壞力也更大。海平面的冰塊開始溶化，永久凍土也開始解凍，冰山開始消退。分享友人
