This is a wrong acknowledge, had said to be able to not give cabin immediately without who.
Without giving thought to space shuttle (low-pressure environment) it may not be a bad idea, submarine (high-pressured environment) . The pressure that gets is by it is action directly at equipment itself, the meaning is exterior bear pressure. Do not have any influences to interior. So the mobile space of the person inside is an atmospheric pressure that balances with human body.
Without giving thought to much deeper, also won't affect a person. Be just like the iron case that puts you in to bear fruit in, bury on a few tons of earth to you above, the pressure that earth brings was borne by the box, can not overwhelm you, at most you are can frowsty inside. Bear without the box pressure, can think the person is met how. So diver gives cabin directly is to do not have how old of the problem.
Of the need decompression process that you say is additionally one kind of dive. Be called saturated dive. What is saturated dive? The meaning is the operation that the person carries oxygen to expose Yu Shuizhong directly continuously. We know water submergence deepness is deeper, the pressure of water is greater. In shallow water area, the ordinary air after person breath is compressed goes. But increase as deepness, underwater breathed common oxygen bottle to won't do. The oxygen gas cylinder of special processing wants to carry. But aerobic bottle also is not pure oxygen. Pure oxygen can make philtrum poisonous. So other gas scale is in inside.
Get in human body after high pressure, special lung, can produce the 5 atmosphere standards to 10. Below high pressure, the nitrogen that contains among them can not participate in human body the chemical reaction of each cell material, as heighten of content of human body nitrogen, nitrogen will be paralytic human body. This still passes the person of special training.
More than these, paralytic human body does not say, because be not participated in of nitrogen, at this moment the gas mixture that what human body breathes is inert gase and the oxygen such as helium. And be in harmony of the meeting after inert gase is inspiratory receives human body blood. If do not press regulations to have reduce pressure, rapid rise, deliquescent the inert gase inside body can be decreased suddenly because of pressure, bleb is formed in the joint of diver or body organization, scathing cerebra, body material, can endanger life even.
So, go under water is deeper, rise rate is about to jump over slow, should let the body have slowly get used to a process. Deep-sea fish is salvaged won't do alive, it is a truth.
