信息輸入是數(shù)控車床自動編程系統(tǒng)的第一個環(huán)節(jié)，提出信息輸入建模方法的研究，旨在解決NC本削自動加工所需數(shù)據(jù)的輸入，存儲和快建傳遞的問題。

　　This paper aims at discussing the research of information input process and storage method which are used in NC programming system.

　　節(jié)點布置是無線傳感器網(wǎng)絡(luò)（Wireless Sensor Network，WSN）的一個基本問題，是對監(jiān)測區(qū)域的有效覆蓋，也是網(wǎng)絡(luò)初始化的第一個環(huán)節(jié)。

　　Sensor deployment is the basic problem in Wireless Sensor Network ( WSN), which is also made to cover the monitored area efficiently and the first step for sensor network initialization.

　　由于流程建模是進行BPR的第一個環(huán)節(jié)，所以選擇合適的工具尤為重要。

　　Because process modeling is the first tache to carry through BPR, it is very important to choose appropriate tools.

　　Boot loader也是嵌入式系統(tǒng)軟件開發(fā)的第一個環(huán)節(jié)，它將軟硬件緊密地銜接在一起，這對于一個嵌入式設(shè)備后續(xù)的軟件開發(fā)至關(guān)重要。

　　Boot Loader is the first link in embedded system software development, and intimately connected hardware with software. It is important for a follow-up of embedded system software development.
