In the end the calculation method of directional barrel's parallelismerror is given.
给出了定向管平行度误差的计算方法。

In measuring and evaluating the parallelismerror with the leveler, data processing is conventionally carried out by manually graphic and calculation methods according to the data measured.
在使用水平仪对平行度误差进行测量及评定时，目前一直沿用着用手工按图解法或计算法进行数据处理。
