## 根因

雪崩碎屑像流化体一样运动；游泳或侧滚无效，因为雪太密且湍急，无论受害者如何移动都会被迅速掩埋。

## 解决方案

1. ```
   If caught, deploy an avalanche airbag backpack immediately (pull handle). Airbags increase buoyancy and reduce burial depth by keeping victim near the surface.
   ```
2. ```
   Perform the 'avalanche swim' technique correctly: try to move to the side of the avalanche (not against flow) and create an air pocket in front of your face as the snow slows. Use one hand to clear space.
   ```
3. ```
   Carry and know how to use avalanche transceiver, probe, and shovel. Practice companion rescue drills. Most survival depends on rapid extrication by companions within 15 minutes.
   ```

## 无效尝试

- **** — Spreading limbs increases surface area but also increases torque, causing tumbling and disorientation (80% 失败率)
- **** — Avalanche snow moves at 80-200 km/h; jumping is impossible due to force and disorientation (90% 失败率)
- **** — Poles and axes are ripped from hands instantly; attempting to anchor increases injury risk from impact with rocks/trees (85% 失败率)
