dividing filter

To eliminate the ECG signals noises mentioned above, this paper adopts LMS adaptive algorithm and wavelet transform theory to design three kinds of digital adaptive filters& adaptive noise cancellation filter, wavelet transform filter and adaptive signal dividing filter to filter the corresponding noises.

为了消除心电信号检测过程中带有的上述三种噪声，采用LMS自适应算法及小波变换理论，有针对性的设计了自适应滤波器、小波变换滤波器和自适应信号分离器等三种数字滤波器来滤除相应干扰。

By dividing the fiberglass filter into several layers with different mass thickness, the deposition distribution of α particles sampled in the filter is measured and the relation of the deposition with mass thickness is obtained.

对采样在玻璃纤维滤纸上的α气溶胶粒子进行分层测量，得出α粒子在滤纸中随质量厚度的沉积分布规律，进而求得了沉积分布函数。
