该文简述了在反射系数为白噪声条件下探地雷达记录道中零相位子波的提取，并用提取的子波对探地雷达信号进行互相关滤波的方法原理及编写的相应的程序。

In the precision light screen velocity measuring system, a signal processing technology based on the arithmetic of image processing is put forward to eliminate the interference of random noise to opto-electronic detected signals, so the interval time of the object flying through the two light screens can be gained accurately.

在光幕靶精密测速系统中，提出了一种基于图像处理算法的信号处理技术，消除随机噪声对光电探测信号的干扰，从而可以精确获取物体通过前后两光幕靶的间隔时间。

With the description of the measurement error as Gaussian random variable,the error of real-time measurement of slow fading signal with the RAKE receiver is analyzed.

本文研究了宽带衰落信道中慢衰落信号的实时测量，通过将测量误差描述为高斯分布的随机变量，分析了利用RAKE接收机实时测量慢衰落信号的误差。

Although plenty of useful information on kinematics and dynamics is contained in the three-component seismic data,the signal is usually contaminated by all kinds of random noise,which brings up some obstacles for data processing and interpretation.

三分量地震资料包含着丰富的运动学和动力学信息，各种随机噪声的存在严重降低了资料的信噪比，给有效信息的提取带来了一定的困难。

Each test signal of tank gun control test system usually has random disturbance , real-time recurrence filtering for test signals is performed by means of Kalman filtering.

火炮控制检测系统各检测信号大多含有随机干扰，利用卡尔曼滤波可对检测信号进行实时递推滤波。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
