【摘要】:正{1}水肺潛水?dāng)z影的技巧水肺(英文縮寫為SCUBA)又叫自攜式水下呼吸裝置,人們潛入水中,必須依靠它來自由呼吸。水肺潛水?dāng)z影(簡稱水下攝影)指的是攝影者攜帶水肺潛入水下所進(jìn)行的攝影活動,圖1。由于潛入水中每增加10米,水中的氣壓就增加1個大氣壓,水肺具有自動調(diào)節(jié)壓力的功能,使?jié)撍吣軌蚝粑脚c地面空氣相同壓力的空氣。目前的水肺一般允許潛水者在不超過40米深的水下工作兩個小時。
[Abstract]:The technique of scuba diving photography (SCUBA) is also called self-propelled underwater breathing device. People must rely on it to breathe freely when they dive into the water. Scuba diving photography (underwater photography for short) refers to the photographic activities of the photographer who submerges underwater with the water lung. Fig. 1. As the air pressure in the water increases by 1 atmospheres for each increase of 10 meters in the water, the lungs have the function of automatically regulating the pressure, so that the divers can breathe the same air pressure as the air on the ground. The current lungs generally allow divers to work for two hours under water not more than 40 meters deep.
