Based on the phase shift pulse width modulation technology, the mathematical non-linear model is developed.

基于移相载波调制，建立了变频器的非线性数学模型。

It is called a shift register because the data is shifted through the register by one bit position on each clock pulse.

这就是移位寄存器，因为数据在每一个时钟脉冲的作用下通过寄存器会移动一位。

Control pulse is coupled into this pulse shaper by wavelength division multiplexer. Nonlinear phase shift of signal laser is induced by control pulse because of cross phase modulation.

该全光脉冲整形器利用波分复用器将控制光脉冲引入光纤环形镜中，控制光脉冲由于交叉相位调制在信号光上产生了非线性附加相移。

This relatively minor shift, the model found, still produces enough energy to initiate a wave-like pulse of crystal-shattering snow separation that quickly propagates uphill and leads to a major release of the upper layer.
