I've come to get it back from him.

我是来从他那里把它取回来的。

Our dutiful guide, a girl from Taiwan whose last name was Wang, told us that since we had come all the way to Paris, we would not waste our time if we got our portraits drawn.

汪小姐对大伙说，来一次巴黎不容易，如果有人愿意在这儿取一幅粉笔画回去，说不定是个有意义的纪念。我也觉得是这样。

If vintagers came upon you, they would leave no gleanings; If thieves by night, they would destroy as they pleased.

This new kid is a real greenhorn so I asked him to go get me a left-handed hammer .

他说：他要那新来的小伙子为他取一把左手用的锤子。

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.

In this approach, a homography matrix between the ground plane and the image plane is obtained by least square.

它首先利用地平面与图像中的对应点建立一个对应矩阵（homogra-phy），然后利用已知的摄像机高度以及地面上垂线在图像中的投影等约束信息来求取摄像机的参数。

He called to the hostler to fetch a peck of oysters , and give them to his horse .

于是，他让旅店里的马倌去取些牡蛎来喂他的马。

The split between the two groups can hardly be papered over.
