经鱼骨传导游泳训练,耳机使用教程, 长按中间功能键开机,数字闪烁为阳光下视频拍摄效果。实物如图,请放心使用。 主机耳机均配备十六组信道可供使用。一个主机像可连接 x 耳机 同样长按耳机中间功能键开机, 长按耳机加号键上升频道档案则是增大音量。耳机 切换频道采用语音播报,频道一致即为连接成功。 当同一泳池有多组学员和教练时,可将主机耳机切换至其他信道,轻松实现多组教学。 注意,多个主机发射机在同一性道下会冲突扳倒。例如两个主机接在十六频道同时使用。 主机充电状态为蓝色,电量充足为绿色,电量低。屏幕显示二零 耳机充电,蓝色指示灯亮起,电量充足。绿色指示灯亮起,电量不足。红色指示灯快闪并伴有频繁低声。 注意充电前请擦除充电口附近的水渍。以上为所有使用教程。

understanding the physics of swimming is a key element to help you swim faster it doesn't matter if you're a beginner or an experience swimmer on this video, we will go overboardency meaning the ability to float how do you float to understand why something or someone floats? you need to understand our comedies principle let me try to explain it on simple terms and then if you want a more scientific explanation, i will leave a link in the description for you when you're in the water, you push some of it to the sides and then up just like when you get in the hot tub, you displace the water and the level rises however, in the swimming pool, gravity is going to pull that water that you lift it up back down, so so that water pushes you up with the same amount of force that you push it this equilibrium of forces makes you float how can some people seem to float? more easily than others? this all depends on the density of the body essentially density refers to how close the atoms in an object are from each other the more dense an object is the closer the atoms are and the less it floats for example, a rock is very dense meaning that it has a lot of weight compared to its mass muscle is more dense than fat。 so a thick person with very little fat in their body floats less than a baby that has very little muscle and light bones a person with more or body fat will also float more why is this important when you're swimming, you have a center of buoyancy and you always have a center of mass, your center of mass is very close to your bellybug but your center of point c is close to your lungs this is because the air in your lungs is not dense at all and it floats more so if you stand still these two centers will align with gravity that is also why if you blow all the air in your lungs, you sink to the bottom of the pool for optimal swimming you need a horizontal position how do you float in a horizontal position? by changing your center of buoyancy keeping a good amount of airing your lungs and by kicking if you have your arms up, the center of buoyancy gets closer to your belly button and by kicking you create an upward force that makes the water push you up。
