到深海去考察,向海底要宝藏,这是人类几千年来梦寐以求的。水下无人航行器即俗称潜水机器人便是现代科技打造的探海利器。人体水下的限制人的身体直接进入水中,无论是时间或是深度都极为有限。水深每增加10米,水压就要增加约一个大气压,而且人肌体组织和血液中溶有氮气,压力增大氮气溶量增加,当压力突然减少或解压时,氮气就迅速逸出,形成气泡,造成血管堵塞、肌体破坏,甚至死亡,这便是通常所说的减压病。一些潜水作业者和潜水运动员,经过长期训练,可不靠任何器具在较深的水中较长时间憋气。例如日本一些沿海地区的渔业妇女,通过长期生产活动练就了一身潜水的好本领,可不带氧气呼吸器具、不穿潜水服,
Go deep into the sea to study, treasure to the sea, this is human dreams for thousands of years. Unmanned underwater craft that is commonly known as diving robot is the modern science and technology to build a sea exploration weapon. Underwater human body limits the human body directly into the water, both time and depth are extremely limited. For every 10 meters of water depth, the water pressure will increase by about one atmosphere, and nitrogen dissolved in human body tissues and blood will increase the pressure of dissolved nitrogen. When the pressure suddenly decreases or decompresses, the nitrogen rapidly escapes to form bubbles , Causing blood clots, body damage, and even death, which is commonly referred to as decompression sickness. Some scuba divers and divers are long-time trained to hold their breath in deeper water without any equipment. For example, fishery women in some coastal areas of Japan have trained themselves in diving skills through long-term production activities without using oxygen breathing apparatus and wetsuits,
