部队的军事行动都是在一定的地形条件下进行 ,都必需考虑地形条件的影响 ,而使用军用地形图 ,在量读距离、计算面积时 ,必需使用坡度改正数进行修正 ,力求使图上作业的结果与实地相符。否则 ,直接影响作战行动组织计划的严密性。 The military operations of the armed forces are all conducted under certain topographical conditions. All of them must consider the impact of the terrain conditions. When using the military topographic maps, when reading the distance and calculating the area, they must use the correction of the slope correction to make the work on the map The results match the field. Otherwise, it will directly affect the rigor of the plan of operations organization.
