1·The slope selectivity and the stopband of the filters are further improved by utilizing a combination of source-load coupling and over-moded cavities in the same filter.

在同一个滤波器中同时使用源端负载端耦合和多模腔融合技术，使滤波器的频率选择斜率和阻带性能得到改善。

2·Results show that the effect of projection noise on the reconstructed fields is represented by a slope function related to the filter used in deflection tomographic filtered back-projection algorithm.

因此提出了改进的偏折层析滤波反投影算法，数值模拟表明，改进算法在有效抑制倾斜现象的同时，对重建结果不会造成明显的失真。

3·Median filter is a common denoising algorithm. This paper proposes a new adaptive weighted algorithm based on the slope of the curved liner.

中值滤波是常用的降噪算法，本文提出了一种基于窗口拟合曲线的斜率信息的自适应加权算法。
