Molchanov wave 2 - Equalisation:Frenzel

---

1 . The main difference between equalisation in Wave 1 and 2 is the amount of air available for equalisation . It is easy to move large portions of air from the lungs to mouth at shallower depths , but at deeper depths , as we approach residual volume , we will need to learn to move smaller portions of air to the mouth.

1. 在wave1和2中，平衡的主要区别在于可用的空气量。在较浅的深度将大部分空气从肺部输送到口腔是很容易的，但是在较深的深度，当我们的肺部接近残余气量时，我们需要学会将较少的空气输送到口腔。

2 . Freedivers at Wave 2 are advised to master the Frenzel technique . To do this , one needs to develop better control of the breathing muscles , including the diaphragm and intercostal muscles , and not involve them in moving air from the lungs to the mouth.

我们建议wave2水平的自由潜水员掌握法兰左平衡法。要做到这一点，我们需要更好地控制呼吸肌肉，包括横膈膜和肋间肌，让他们不要参与从肺部到口腔的空气流动。

3 . A freediver has to equalise pressure in the middle ear regularly throughout the dive ( roughly every 1-2 movement cycles to begin with ) . In time , the tympanic membrane and the auditory tubes will adapt to pressure changes , becoming more flexible. As this begins to happen you will be able to increase the interval between successive equalisations.

在潜水过程中，自由潜水员必须定期平衡中二的压力（以大约每1-2个运动周期一次开始）。随着时间的推移，鼓膜和耳咽管将适应压力的变化，变得更加灵活。这时，你将能够增加平衡耳压之间的间隔时间。

4 . There are few tips for facilitating ear equalisation as follows : relax the neck and face muscles descend more slowly , equalise the pressure more
often , start equalising earlier and descend along a diagonal trajectory , rather than straight down.

以下是一些有助于耳朵平衡的小窍门：放松颈部和面部肌肉，更慢地下降，经常地平衡耳压，尽可能早地平衡耳压，平缓倾斜地下潜，而不是直线下潜。
