明年还穿这身衣服滑吗？偶遇的话能拜见大神吗？

阿拉布：提醒一下，胸与板头朝向一致的位置，也就是旋转/轴转的中性点，不是弧顶。

我不知道旋转/轴转中性 ...

你引用的资料是Bob Barnes制作的回转序列图，所以要解读的话还是要尽量从原始资料理解比较准确。

BB定义的中性区/点有四种：

转弯中性区："Turn Neutral"—the moment a new turn begins—the end of one turn and the beginning of the next, when turns are linked, as the red circles indicate. It is the point at which the paths of the feet and the center of mass cross, when viewed from directly overhead. Because turns generally begin at some angle across the slope, the "default" characteristics of turn neutral include 1) some degree of "counter" and uphill tip lead, as the legs are rotated in the hip sockets, 2} skis approximately level—not flat on the snow—and at "critical edge angle" (see), and 3) somewhat more pressure on the downhill or new inside ski—not "50:50." (Note that real turns will often show situation-based variations from these "default" characteristics.)

旋转中性区： “rotary neutral” — skis pointing straight ahead with no lead
立刃中性区：“edge neutral” — skis flat on the snow surface
压力中性区：“pressure neutral” — balance 50-50 on both skis

=====================================

至于说红线蓝线的切线，再说一遍，”面向COM前进方向“只是一种意识引导，或者说提示，而不是标准，所以用切线来定义身体朝向是非常不准确的。

具体的身体朝向问题，是跟滑法相关的，并不能一概而论。BB的回转图就是定义了一种”标准滑法“，而后在这个基础上分析。直接把BB的回转图套用到别的滑法，那可能会有完全错误的结论。
