潛(qian)(qian)(qian)(qian)水(shui)(shui)工(gong)程作業中(zhong)下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)和(he)上升(sheng)都要做(zuo)輕(qing)松下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)和(he)上升(sheng)的工(gong)作。這是因(yin)為(wei)很(hen)多人(ren)剛(gang)開(kai)始(shi)下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)的時候(hou)并不(bu)是很(hen)輕(qing)松，因(yin)為(wei)浮力控制(zhi)不(bu)好，然(ran)后下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)速(su)度稍(shao)微快(kuai)了一點。會出(chu)現(xian)緊張過(guo)度，輕(qing)松下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)我們可(ke)以選擇水(shui)(shui)底斜坡或(huo)者(zhe)下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)繩(sheng)來控制(zhi)下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)速(su)度，如果你的面鏡出(chu)現(xian)擠壓(ya)，你可(ke)以通過(guo)鼻(bi)子呼氣來平衡(heng)，如果你的耳朵出(chu)現(xian)擠壓(ya)疼痛，你要停止下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)，然(ran)后上升(sheng)到(dao)淺一些(xie)的深度，直到(dao)耳朵感(gan)到(dao)不(bu)適消失為(wei)止，然(ran)后捏住鼻(bi)子鼓氣或(huo)者(zhe)吞(tun)咽(yan)口(kou)水(shui)(shui)和(he)下(xia)(xia)(xia)(xia)巴左右擺(bai)動再慢(man)慢(man)地(di)下(xia)(xia)(xia)(xia)潛(qian)(qian)(qian)(qian)。傷風感(gan)冒時 別潛(qian)(qian)(qian)(qian)水(shui)(shui)。而上升(sheng)中(zhong)做(zuo)輕(qing)松上升(sheng)，也是同理(li)。

  ，在潛水(shui)下堵漏工程作業的(de)(de)(de)(de)時候，因為工作或其他(ta)原因，有時就會忘(wang)記看自己的(de)(de)(de)(de)氣(qi)(qi)(qi)瓶里殘(can)余的(de)(de)(de)(de)空(kong)氣(qi)(qi)(qi)量(liang)，如果等(deng)到他(ta)們沒有氣(qi)(qi)(qi)吸的(de)(de)(de)(de)時候已(yi)經(jing)來(lai)不(bu)及了。這個時候剛剛好他(ta)們的(de)(de)(de)(de)潛伴就在身邊，所以必須要(yao)用(yong)潛伴的(de)(de)(de)(de)備用(yong)氣(qi)(qi)(qi)源(yuan)來(lai)呼吸，然后離開水(shui)底上(shang)升到水(shui)面上(shang)來(lai)。
