D Match any decimal digit, same as [0-9] \D is inverse of \d: do not match any numeric digit

d 匹配任何数字，和 [0-9] 一样 \D 是 \d 的反义：非任何数字

Because the signal now resides in the digital domain, you can apply a lowpass digital filter to attenuate the higher frequency noise and a decimator filter to slow down the out

因为信号位于数字域，可以采用低通数字滤波器削弱高频率噪声，采用抽取滤波器减小输出数据的速度。

The system is composed of trust model, structure and function design, certificate database design, and implements the core functions of a standard CA system including signing, issuing and revoking certificates. The security communication modular of the system is based on the SSL Protocol to enhance the security of system communications. Besides, the kernel functions of the system are packed into DLL library, including symmetrical encryption algorithms, digest algorithms, digital signature algorithms and certificate operations such as certificate request, certificate building, certificate format conversion etc.

本文的主要工作是：在研究PKI相关技术的基础上，设计了企业CA系统方案，包括信任模型、结构和功能设计、证书库的设计；实现CA系统中最为核心的数字证书管理，提供数字证书的签发、注销和发布等各项功能；实现了基于SSL协议安全通信模块，增强了系统通信的安全性；系统采用动态链接库技术封装了对称加密算法、数字摘要算法、签名算法以及证书处理(包括证书请求、证书生成、证书格式转换等功能)，以动态链接库的形式提供调用接口，成为应用的安全基础设施。

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.
