There is a lot of noise in the data observed by airborne gravimeter. Digital lowpass FIR-filter is needed to extract the factual gravity field information from such data.

航空重力测量数据中含有大量的噪声，需要采用FIR低通滤波器来提取实际的重力异常信息。

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea,a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious.

该文根据地海杂波与流星干扰在多普勒谱上的差别，提出了用FIR型高通滤波器滤除杂波使流星干扰凸显出来；再根据流星干扰的分布特点分段计算背景噪声均值，求取流星干扰检测门限；最后用杂波信号来插值流星干扰位置上的数据，消除因去除干扰造成的杂波相位不连续。

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea, a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious. Then a smart threshold is obtained from the minimum mean of different segments of background noise and used to detect the meteor trail echo. Finally the phase discontinuity of clutter from the meteor trail echo suppression is eliminated by substituting the data at echo positions with clatter.

该文根据地海杂波与流星干扰在多普勒谱上的差别，提出了用FIR型高通滤波器滤除杂波使流星干扰凸显出来；再根据流星干扰的分布特点分段计算背景噪声均值，求取流星干扰检测门限；最后用杂波信号来插值流星干扰位置上的数据，消除因去除干扰造成的杂波相位不连续。

Designing FIR filer actually means solving a group of fine coefficients.

FIR滤波器的设计最终可归结为求解一组滤波器系数，采用最小二乘法优化这些系数。

But something else in her was strange and inert and heavy. His body was urgent against her, and she hadn't the heart any more to fight. He looked around. 'Come---come here! Through here,' he said, looking penetratingly into the dense fir-trees, that were young and not more than half-grown.

最后，她决定出去散散步，并不是到树林，而是向相反的方向去，她可以从大花园的其他一面的小铁门里出去，到马尔海去，那是一个宁静而灰色的春日，天气差不多可说是温暖的，她一边走着，一边沉味在飘渺的思想里，什么都没有看见。
