信息輸入是數控車(chē)床自動(dòng)編程系統的第一個(gè)環(huán)節，提出信息輸入建模方法的研究，旨在解決NC本削自動(dòng)加工所需數據的輸入，存儲和快建傳遞的問(wèn)題。

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

　　節點(diǎn)布置是無(wú)線(xiàn)傳感器網(wǎng)絡(luò )（Wireless Sensor Network，WSN）的一個(gè)基本問(wèn)題，是對監測區域的有效覆蓋，也是網(wǎng)絡(luò )初始化的第一個(gè)環(huán)節。

　　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，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也是嵌入式系統軟件開(kāi)發(fā)的第一個(gè)環(huán)節，它將軟硬件緊密地銜接在一起，這對于一個(gè)嵌入式設備后續的軟件開(kāi)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.
