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

进技术进步，在地区试点的基础上，全面实施增值税转型改革，将机器设备纳入增值税抵扣范围。
从我国现实的情况来看，根据我国现行的增值税和营业税制度，我国增值税的税基主要是第二产业中的工业和第三产业中的批发零售业的增加值，营业税的税基是第二产业中的建筑业和第三产业中除批发零售业外的其他行业的流转额。因此，在我以及两者相对比重的变化都和我国的产业结构有着直接的关系。改革开放以来，随着经济的高速发展和产业结构的不断升级，服务业在国民经济中所占的比重也越来越大，尤其在经济发达地区，例如，2011年，%；北京市第三产业占GDP比重为75%
