信息輸入是數(shù)控車床自動(dòng)編程系統(tǒng)的第一個(gè)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(dòng)加工所需數(shù)據(jù)的輸入，存儲(chǔ)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(diǎn)布置是無線傳感器網(wǎng)絡(luò)（Wireless Sensor Network，WSN）的一個(gè)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(gè)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(jìn)行BPR的第一個(gè)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(gè)環(huán)節(jié)，它將軟硬件緊密地銜接在一起，這對于一個(gè)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.
