摘　　要：通过用合像水平仪测量直线度误差实例,分析了在测量过程中如桥板定位、数据处理和图线绘制时容易忽略的问题,采用正确的方法可减小测量误差。An experiment about measuring straight error by split-image levelling instrument is presented. Some important but easily neglected problems are analyzed. These problems are always happened in the measuring process such as bridge plate positioning, data processing and drawing lines. The proper method is adopted to minimize the measurement error.
