摘　　要：本文扼要地介绍了专门用于加速度计静态标定的ＰＢＴ—Ⅰ型双轴转台的工作原理、性能和构造。基于地球上给定地点的重力加速度（ｇ）为一恒量和转角的准确测量，给出了加速度计主要参数（灵敏度、线性度和横向灵敏度）的标定方法和步骤。Principle, function and construction of the PBT-1 biaxial tilting table for calibrating accelerometers are described in this paper. Based on a constant value of gravitational acceleration at a given location of the earth and accurate measurement of tilting angle of the table, a calibrating method and procedure for primary parameters of accelerometers, i.e. sensitivity, linearity and cross axis sensitivity, are presented.
