当波长趋于零时，折射系数都趋于1，这是由于脉冲激光的频率增高，等离子体中产生了非常强的“透镜”效应所至。
When the wavelength tends to zero, the refraction coefficient will tends to 1. Because with the frequency of pulse laser is going up, the very strong "Lens" effect will be produced in plasma.
推测形成这种运动方式的原因是造山带闭合时的斜向碰撞和造山带前缘准噶尔地块的透镜体边界效应。
This is attributed to the oblique collision during closing of the belt and the lens-effect of the Junggar massif in front of the belt.
