1、傅里叶频谱分析。在信号分析中,空间变化的信号与时间变化的信号是相同的。 Application of these techniques to temperature sensing is based on the observation that die temperature is simply a space-varying signal, and that space-varying signals are treated identically to time-varying signals in signa ...
Touch file DNS 域名解析,方便记忆 hosts 文件是 Linux 系统上一个负责 ip 地址与域名快速解析的文件,以 ascii 格式保存在 /etc/ 目录下。 hosts 文件包含了 ip 地址与主机名之间的映射,还包括主机的别名。在没有域名解析服务器的情况下,系统上的所有网络程序都通过查询 ...
