关于6050，当X的旋转角达到90°时，Y轴的角度会突变达到100多度，为什么呢？

发现一个问题：这个我也尝试了，确实出效果了。但是有一个可能大家没有注意到的问题，就是当只绕着某一个轴(Y轴)旋转到86度的偏角时，输出的Awz[0](即Awz_X)也准确接近86度，此时另一个角度Awz[1](即Awz_Y)不变，接近0；但继续旋转到90度时，虽然Awz_X也精确到90度，但另一个角度Awz[1](即Awz_Y)的角度迅速逐步增加，达到100多度，这个很奇怪呢！正常来说，绕某个轴旋转，应该只有一个角度变化，而另一个角度是不会有太大变化，所以请问下这个是什么原因？

如上是我在一楼链接中打印出来的log，在Awz_X旋转达到86°以前，YAwz_Y的角度基本不变；但是随着Awz_X逐渐达到90°时，Awz_Y为什么会达到100多度呢？

当Awz_X继续旋转到96°时，Awz_Y基本保持在160~180°之间，相对稳定；所以目前的变化主要是在Awz_X旋转角度在86°~96°之间时，另一个角度Awz_Y为什么变化这么大呢？
