style="text-indent:25px"> 潛水后為什么身體里有氮氣？人在水底的時間越長，下沉的深度越深，在壓力的作用下身體吸收的氮氣就會越多。那么在上升的過程中水壓減小，多余的氮氣會開始釋放排出，但是這種釋放是緩慢的，如果你上升的速度過快，多余的氮氣會來不及釋放，就會存在身體內(nèi)不同部位，如同有碳酸的汽水，這種沒有釋放完全，殘留在體內(nèi)的氮氣會對人體造成非常的嚴重傷害。潛水的原意是為進行水下查勘、打撈、修理和水下工程等作業(yè)而在攜帶或不攜帶專業(yè)工具的情況下進入水面以下的活動。后潛水逐漸發(fā)展成為一項以在水下活動為主要內(nèi)容，從而達到鍛煉身體、休閑娛樂的目的的休閑運動，廣為大眾所喜愛。</p><p style="text-indent:25px">學性質(zhì)：十分穩(wěn)定，只有在高溫高壓并有催化劑存在的條件下，氮氣成分可以和氫氣反應(yīng)生成氨。同時，由于氮分子的化學結(jié)構(gòu)比較穩(wěn)定，氰根離子CN-和碳化鈣CaC2中的C22-和氮分子結(jié)構(gòu)相似。正價氮呈酸性，負價氮呈堿性。不同活性的金屬與氮氣的反應(yīng)情況不同。與堿金屬在常溫下直接化合；與堿土金屬 —般需要在髙溫下化合；與其他族元素的單質(zhì)反應(yīng)則需要更高的反應(yīng)條件。氮氣在大氣中含量雖多于氧氣，但是由于它的性質(zhì)不活潑，所以人們是在認識氧氣之后才認識氮氣的。不過它的發(fā)現(xiàn)卻早于氧氣。大氣中約有4,000萬億噸氣體，其中氮氣占78%。氮氣微溶于水和酒精。</p><div style="width:100%;text-align:

氮氣是無色無味氣體，是地球大氣中**多的氣體，占大氣體積的78%。其化學性質(zhì)很穩(wěn)定，在一般條件下不支持燃燒，但在一定條件下也能跟其它物質(zhì)發(fā)生化學反應(yīng)。氮氣是化工生產(chǎn)的重要原料，主要用于合成氨，制氮肥、***等。氮氣還可用做焊接某些金屬時的保護氣，使燈泡經(jīng)久耐用的填充氣，糧食、水果在低氧高氮的環(huán)境中能夠保鮮、儲存時間長。液態(tài)氮可作深度冷凍劑，如用于研究超導技術(shù)和材料等。發(fā)現(xiàn)1772年在蘇格蘭愛丁堡，由。1774年法國，含義是無益于生命。氮的英文名稱來源于希臘文nitre，含義是硝石。制備工業(yè)上常用低溫分餾空氣的辦法把氮氣和氧氣分開。工業(yè)氮氣都用黑色鋼瓶裝。海南州氮氣誠信互利。海南州氮氣廠家實力雄厚</p><p
