極大(da)限度(du)地排(pai)除空(kong)氣(qi)中(zhong)的(de)(de)氧(yang)(yang)氣(qi)、硫、油、水(shui)和(he)其它雜質，有效降(jiang)低了(le)輪胎(tai)內襯層的(de)(de)氧(yang)(yang)化(hua)(hua)程度(du)和(he)橡(xiang)膠被腐蝕(shi)的(de)(de)現象，不會腐蝕(shi)金屬輪輞(wang)，延長了(le)輪胎(tai)的(de)(de)使用壽命，也(ye)極大(da)程度(du)減少輪輞(wang)生銹的(de)(de)狀況。充了(le)氮(dan)氣(qi)的(de)(de)輪胎(tai)還可以防止(zhi)輪胎(tai)自然氧(yang)(yang)化(hua)(hua)和(he)龜裂(lie)，因為純凈(jing)的(de)(de)氮(dan)氣(qi)不像空(kong)氣(qi)那樣(yang)含有包括水(shui)在(zai)內的(de)(de)多(duo)種(zhong)成分，因此對橡(xiang)膠的(de)(de)腐蝕(shi)性(xing)小，能(neng)夠延長輪胎(tai)的(de)(de)使用壽命。常溫(wen)下(xia)，氦氣(qi)是一種(zhong)極輕(qing)的(de)(de)無(wu)色、無(wu)臭、無(wu)味(wei)的(de)(de)單原子氣(qi)體(ti)(ti)。是所有氣(qi)體(ti)(ti)中(zhong)難液(ye)化(hua)(hua)的(de)(de)，是不能(neng)在(zai)標準大(da)氣(qi)壓下(xia)固化(hua)(hua)的(de)(de)物質。液(ye)化(hua)(hua)后溫(wen)度(du)降(jiang)至2.174K時，具有表面張力很小、導熱性(xing)很強、黏度(du)極低等特殊(shu)性(xing)質。利用液(ye)態氦可以得到(dao)接近零度(du)的(de)(de)低溫(wen)。

氦(hai)(hai)氣(qi)(qi)在(zai)科(ke)學實驗、臨(lin)床(chuang)和工業(ye)生產(chan)上都有(you)(you)(you)著(zhu)非常(chang)廣(guang)泛的(de)(de)用(yong)(yong)(yong)(yong)(yong)(yong)途(tu)。從大(da)(da)(da)型強子對(dui)撞機到(dao)點焊機（一(yi)種焊接機器(qi)），液(ye)氦(hai)(hai)被廣(guang)泛地用(yong)(yong)(yong)(yong)(yong)(yong)來冷卻設備，因為它既方(fang)便(bian)又有(you)(you)(you)效。另外，液(ye)氦(hai)(hai)的(de)(de)用(yong)(yong)(yong)(yong)(yong)(yong)途(tu)是用(yong)(yong)(yong)(yong)(yong)(yong)在(zai)磁(ci)共(gong)振(zhen)成(cheng)像(xiang)(xiang)設備中。磁(ci)共(gong)振(zhen)成(cheng)像(xiang)(xiang)可以(yi)應(ying)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)全身(shen)各系統(tong)的(de)(de)成(cheng)像(xiang)(xiang)診(zhen)斷，而其設備中的(de)(de)超(chao)導磁(ci)體需要用(yong)(yong)(yong)(yong)(yong)(yong)液(ye)氦(hai)(hai)來冷卻到(dao)接近(jin)零度。這種醫學設備是用(yong)(yong)(yong)(yong)(yong)(yong)氦(hai)(hai)大(da)(da)(da)戶，用(yong)(yong)(yong)(yong)(yong)(yong)氦(hai)(hai)量大(da)(da)(da)約占全世界用(yong)(yong)(yong)(yong)(yong)(yong)氦(hai)(hai)量的(de)(de)1/3。由于(yu)氦(hai)(hai)氣(qi)(qi)比氫(qing)氣(qi)(qi)安全，可以(yi)用(yong)(yong)(yong)(yong)(yong)(yong)氦(hai)(hai)氣(qi)(qi)代替(ti)氫(qing)氣(qi)(qi)充(chong)填飛船、氣(qi)(qi)象氣(qi)(qi)球等。氦(hai)(hai)氣(qi)(qi)還可以(yi)作為色譜和載(zai)氣(qi)(qi)，隨著(zhu)宇宙空間(jian)技術(shu)(shu)、激光技術(shu)(shu)和紅外線探測技術(shu)(shu)的(de)(de)發展，氦(hai)(hai)還有(you)(you)(you)著(zhu)廣(guang)泛的(de)(de)用(yong)(yong)(yong)(yong)(yong)(yong)途(tu)。 利用(yong)(yong)(yong)(yong)(yong)(yong)液(ye)氦(hai)(hai)的(de)(de)-268.9℃的(de)(de)低(di)沸(fei)點，液(ye)氦(hai)(hai)可以(yi)用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)超(chao)低(di)溫(wen)冷卻。而超(chao)低(di)溫(wen)冷卻技術(shu)(shu)在(zai)超(chao)導技術(shu)(shu)等領域(yu)有(you)(you)(you)較(jiao)廣(guang)泛的(de)(de)應(ying)用(yong)(yong)(yong)(yong)(yong)(yong)，超(chao)導材料需要在(zai)低(di)溫(wen)（100K左右）中才能(neng)表現出超(chao)導特性，大(da)(da)(da)多數(shu)情況下只有(you)(you)(you)液(ye)氦(hai)(hai)能(neng)比較(jiao)簡便(bian)地實現這樣(yang)的(de)(de)極低(di)溫(wen)。
