叠加次数 meaning in Chinese
stacking fold
Examples
- Bin stack technology , effectively integrating acquisition and processing technology , is the continuity of high precision 3d acquisition , aiming at increasing reflecting energy , resolution and s / n ration through small bin size acquisition , enlarged bin size processing and increasing cmp fold times . besides 3d acquisition , bin stack can also be used in 2d acquisition
面元叠加技术，是高精度三维地震的延续，它有效地把采集技术和处理技术紧密结合为一体，通过小面元采集、扩大面元处理，提高cmp面元的叠加次数，以达到提深层反射能量、提高分辨率、信噪比的目的。 - In chapter 4 , i performed the analyzing work with wavelet and fastica and find that wavelet was a high efficient way to filter the cep signal when i set the wavelet and scaling function to haar , decomposing level to 4 , threshold method to fixed to threshold and white - noise structure to scaled white - noise . it took the advantage that reduced the accumulating times to 60 with more smooth signal and less distortion . but fastica takes no advantage on this facet
本文通过小波变换和独立分量快速分析模式识别的方法对cep数据进行了分析处理，同时与数字低通椭圆滤波器的处理效果进行了比较，发现用小波对cep的数据进行滤波处理时，可以将数据的叠加次数从120降低到60次左右，且信号的质量要比以前的处理方法好；但是独立分量快速分析方法效果不很好。
