First, by taking into account not only interband effects but also intraband effects, such as carrier heating , spectral hole burning , two-photon absorption and ultrafast nonlinear refraction and the interaction of control pulse and signal pulse in SOA, the relationship between the performance of TOAD (including flatness of switching window, chirp of output signal and extinction ratio of the demultiplexed signal) and the parameters of input pulse (including the wavelength and power of control and signal pulse) are studied.

首先，在考虑到由于带内效应，诸如载流子热效应、谱烧孔效应、超快非线性折射效应和双光子吸收效应而导致得非线性增益压缩效应以及控制光和信号光相互作用情况下，研究了TOAD的各性能参数，包括开关窗口的平坦性、输出信号的啁啾特性、解复用信号的消光比特性等与输入控制光和信号光的波长及功率的关系，在此基础上对TOAD性能进行了优化。

In order to eliminate the aliasing, at each step of decomposition or reconstruction, fast Fourier transform is performed the result obtained by convolving the input signal with filters, setting frequency spectrum of the redunctant frequency components to be zero, and inversely fast Fourier transforms the result after zeroing. The result after processing is the input signal of next step,and single sub-band reconstruction is implemented to extract the feature item of GPS data sequence.

为消除频率混淆现象，分解与重构时，每作一次信号与小波卷积后，将其结果作一次快速傅立叶变换，频谱中多余的频率成分的谱值置零，再对置零后的频谱进行傅立叶逆变换，然后继续进行小波包的分解与重构，从而实现单子带重构提取GPS数据序列特征项。

And then, etiolated seedlings were stressed under the 25℃、0℃、-10℃ and -20℃, which resulted in decrease in POD activity, and that under -10℃ and -20℃ were the weakest, but there were no markedly difference between them. And the POD activity of Jingdong 8 and SCREEM were stronger than others at any temperature.

4种温度条件下25℃时的酶活力较强，0℃次之，-10℃和－20℃较低，且－10℃和－20℃下的酶活力基本一样；在各温度条件下，冬性品种京冬8号和SCREEM均表现出较强的酶活力，但没有特殊的同工酶谱带。
