一、我国黄金产业技术进步现状
经过几十年的发展，我国黄金产业的勘探开发技术和产量都取得很大的进步，我国已经成为黄金生产和消费大国。近年来，我国黄金产量稳步增长，并且建立起了完整的产业链。1949年建国时，，。1978年开始，国家出台扶持政策，黄金产业进入快速发展时期。，到2002年已经上升到190吨，从1979年到2002年，%。2003年黄金产量较2002年增长了10吨，为200吨。2007年超过南非居世界第一，2010年达到340多吨。黄金产量已经跨入世界大国之列，成为重要的支柱产业，黄金产业

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
