This article is primarily about dealing with local files, but it's worth noting that you can grab, echo, and parse other Web pages with these functions, as well. 本文主要介绍的是如何处理本地文件,但是值得注意的是您还可以用这些函数提取、回显和解析其他Web页面。
Trawl through archive copies of the local newspaper, the Dorset Evening Echo, covering the period of that conflict, and a barely-recognisable country swims into view. 翻遍当年报道这场战争的《多塞特回声报》,一个几乎难以辨认的国家重回视线。
In 12 cases of limited acute thyroiditis there were local low echo mass with nch blood flow signal. 12例亚急性甲状腺炎表现为甲状腺内局限性低回声团块伴丰富的血流信号。
By means of the detection and processing of local singularity in signals, the number of echoes is determinated and the arrival instant of every echo is located. The results of computer simulation show that this method is effective. 该方法通过对回波信号的局部奇异性的检测和处理,确定回波数目和定位各个回波到达时刻,计算机模拟的结果证实了本文所提方法的有效性。
In the course of data processing and echo detecting a single echo pulse detection algorithm, the local median filter and of four different echo characteristic time detecting method are used to determine the most accurate echo detection algorithm. 本系统在数据处理和回波检测过程中,采用单次回波脉冲检测算法、局部中值滤波并通过四种不同的回波特征时间进行回波检测,确定了精度最高的回波检测算法。
And the system design which is based on the Matlab/ Simulink comprises the generating of the transmitted signal and local oscillator signal, the analyze of echo, the receiving module, Data sampling and Information processing. 在熟悉Matlab/Simulink强大功能的基础上,开始Matlab/Simulink下仿真系统的详细设计,包括:发射和本振信号产生方式的设计,回波分析,接收模块的分析和设计,数据采集以及信号处理这几部分。
