比较发现胡萝卜醛在甲醇中的瞬态吸收光谱红移，且S1态寿命变短，经分析认为是C=O基团的作用。同时表明SVD方法是处理飞秒时间分辨瞬态吸收光谱有效的工具。

Using triple integral equation based on scalar Green function for forward modeling transient electromagnetic response to a 3 D anomalous body, a frequency response of electromagnetic field component has been evaluated first on frequency domain, then the evaluated results has been transformed into time domain by using fast numeric filtering algorithm.

用基于张量格林函数的体积分方程对三维异常体进行瞬变电磁响应的正演模拟，首先在频率域内计算电磁场分量的频率域响应；然后利用快速数字滤波技术将计算结果转换到时间域。

Namely in high-frequency unit use gradually incisive time resolution and lower frequency resolution, in order to moves the near observation signal quickly to change the part; In low frequency partially has the higher frequency resolution and the lower time resolution, in order to moves the far observation signal slowly to change partially, the wavelet this kind of signal analysing expression characteristic to analyzes the non- steady signal is extremely effective, suits the transient state anomaly very much which smuggles in the survey normal signal and demonstrates its ingredient, therefore by reputation for analysis signal microscope.

即在高频部分使用逐渐尖锐的时间分辨率和较低的频率分辨率，以便移近观察信号的快变部分；在低频部分具有较高的频率分辨率和较低的时间分辨率，以便移远观察信号的慢变部分，小波这种信号分析表示特征对分析非平稳信号是非常有效的，很适合于探测正常信号中夹带的瞬态反常现象并且展示其成分，所以被誉为分析信号的显微镜。
