摘　　要：首先介绍了嫦娥三号任务中，VLBI观测网、VLBI中心的设置和处理流程，然后简单介绍了差分单程测距（delta-differentialone—wayranging，ADOR）处理方法。重点对整个任务期间的观测结果进行了统计分析，并从中选出有代表性的几次任务进行了说明。The background of the VLBI tracking system in the Chang＇e-3 mission, inc[udittg the Chinese VLBI Network （CVN）, the setup for the VLBI observation and the procedure of data reduction, is introduced, along with the processing method for the ADOR （delta differential one-way ranging） technology. In this paper, we focus on the statistic information obtained by analyzing the observations during the whole period of the Chang＇e-3 mission. Through these analyses and studies, several typical sessions are characterized in detail.
