摘　　要：带有光学对点器的经纬仪在安置时要遵循一定的操作程序,即用脚螺旋对中,用架腿整平,一般情况下,只要按照这个程序进行操作,就能够很快将仪器安置好。但是,当标桩凸出地面使标志点距仪器底部较近时使用这个方法会失效,这种情况在野外测量时偶然会遇到。为了解决这个问题,文中对对中整平的原理进行了论述,在此基础上,提出了当标桩高于一定高度时的对中整平方法,该方法可以概括为:用架腿对中,用脚螺旋整平,与常规的操作正好相反。这是一个非常程序化的技术,只要按照这个程序去操作,也能够很晚完成对中整平工作。When we set up a theodolite with optical plummet over a station,we must handle the instrument according to designed rule,such as center it by revolving foot screws,level it by stretching out and drawing back tripod legs.Under ordinary circumstances,the theodolite can be set up quickly,so long as it is operated according to the rule.But when the pillar is overtop the ground and the mark is closer to the boot of the instrument,the method will become invalid,this case is accidently in field surveying.To solve the problem,in this paper,the principle of centering and leveling is firstly discussed,based on which,a new method of centering and leveling is suggested.This new method can be summarized as: to center by stretching out and drawing back tripod legs,to level by revolving foot screws,which is reverse with the usual operation rule.This is a very programming method,we can center and level theodolite quickly according to this rule.
