潛(qian)(qian)(qian)(qian)(qian)水工程作業中下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)和(he)(he)上(shang)升(sheng)都(dou)要做輕(qing)松(song)下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)和(he)(he)上(shang)升(sheng)的(de)工作。這(zhe)是因為(wei)很多人剛(gang)開始下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)的(de)時候(hou)并不是很輕(qing)松(song)，因為(wei)浮力(li)控(kong)制不好，然(ran)(ran)后(hou)下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)速度稍微快了一(yi)點(dian)。會(hui)出(chu)現緊(jin)張(zhang)過度，輕(qing)松(song)下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)我們可(ke)以選擇水底斜坡(po)或者(zhe)下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)繩(sheng)來控(kong)制下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)速度，如果你(ni)(ni)的(de)面鏡(jing)出(chu)現擠壓(ya)，你(ni)(ni)可(ke)以通過鼻(bi)子(zi)呼氣(qi)來平衡，如果你(ni)(ni)的(de)耳(er)朵出(chu)現擠壓(ya)疼痛，你(ni)(ni)要停止下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)，然(ran)(ran)后(hou)上(shang)升(sheng)到淺一(yi)些的(de)深度，直到耳(er)朵感到不適消失(shi)為(wei)止，然(ran)(ran)后(hou)捏住鼻(bi)子(zi)鼓氣(qi)或者(zhe)吞咽口水和(he)(he)下(xia)(xia)巴左右擺動(dong)再(zai)慢(man)(man)慢(man)(man)地(di)下(xia)(xia)潛(qian)(qian)(qian)(qian)(qian)。傷風感冒時 別潛(qian)(qian)(qian)(qian)(qian)水。而上(shang)升(sheng)中做輕(qing)松(song)上(shang)升(sheng)，也(ye)是同理(li)。

  ，在潛水下堵漏工程作業的(de)(de)時(shi)(shi)候，因為工作或其他原因，有(you)時(shi)(shi)就會忘記看自己(ji)的(de)(de)氣(qi)瓶里(li)殘余的(de)(de)空(kong)氣(qi)量，如果等到他們(men)(men)沒有(you)氣(qi)吸的(de)(de)時(shi)(shi)候已經(jing)來不(bu)及了。這個時(shi)(shi)候剛剛好他們(men)(men)的(de)(de)潛伴就在身邊，所以必須要用(yong)潛伴的(de)(de)備用(yong)氣(qi)源來呼(hu)吸，然后離開(kai)水底上升到水面上來。
