Its only required argument is a numericaldistance that identifies how far the extrusion should be performed.
该方法惟一需要的参数是一个数值距离，表明挤压应该执行多远。

Numerical results show that the squeezing ratio decrease at some initial distance when the amplitude increase and the squeezing was best if pluse wave shape near fundamental soliton.
数值结果表明，增大初始振幅在初始一定距离范围内能减小压缩比，接近理想光孤子的脉冲波形压缩效果最好。

Numerical results show that the squeezing ratio largely increase at the nearby of collision distance.
