Defintion: GDP is the total market value of all final goods and services produced by a country. Final versus Intermediate: By \final\, we mean the goods and service that are purchased for final use by purchaser and not for resale or further processing. The meaning intermediate is opposite to final. Value Added: GDP not only reflects the market value of final goods and service, but also reflect the income generated from producing these final goods and service

Balanced search tree: A search-tree data structure for which a height of O(lg n) is guaranteed when implementing a dynamic set of n items

采用计算机对生产过程进行监视和测量的系统，一般称 为数据采集系统 (Data Acquisition System 简称DAS)，或称为 计算机安全监视系统、计算机信息处理系统、数据采集监视 和处理系统等。 国外最早应用计算机对生产过程进行监视和测量在60年代 初期，据统计，1968年时美国在火电厂应用计算机已多达190 多台，其中70%左右为纯粹的DAS系统，30%左右除DAS系统 以外，少部分具有的运行控制功能
