摘要
针对 JDY- 4型测长仪的边界区域产生的一种未定粗大误差进行实验研究 ,作出误差分布曲线 ,找到产生误差的原因 。
An experimental research is conducted on the uncertain parasitic errors of model JDY 4 Length Surveying Instrument along the border area in order to make out the error distribution cvrve and find out their causes .As a result,two solutions are proposed.
