實則注解： 基礎平板1、窄面(mian)檢(jian)測(ce)(ce)橋(qiao)板(ban)(ban)(ban)比寬面(mian)橋(qiao)板(ban)(ban)(ban)打仗精度(du)(du)高； 2、寬面(mian)檢(jian)測(ce)(ce)橋(qiao)板(ban)(ban)(ban)比窄面(mian)檢(jian)測(ce)(ce)橋(qiao)板(ban)(ban)(ban)易實現現首尾(wei)(wei)點銜接，從檢(jian)測(ce)(ce)利便(bian)思索，選(xuan)寬面(mian)檢(jian)測(ce)(ce)橋(qiao)板(ban)(ban)(ban)較好； 3、檢(jian)測(ce)(ce)橋(qiao)板(ban)(ban)(ban)支(zhi)承(cheng)面(mian)寬度(du)(du)加(jia)大(da)到10mm，測(ce)(ce)點值雖(sui)有(you)變(bian)化，但立體度(du)(du)值變(bian)化不大(da)，注明寬度(du)(du)加(jia)大(da)到10mm時橋(qiao)板(ban)(ban)(ban)仍(reng)用(yong)； 4、檢(jian)測(ce)(ce)橋(qiao)板(ban)(ban)(ban)支(zhi)承(cheng)面(mian)長(chang)度(du)(du)對丈量下場影響(xiang)不大(da)；鉗工平臺 5、在_高精度(du)(du)打仗的前提(ti)下，只管即便(bian)選(xuan)用(yong)檢(jian)測(ce)(ce)利便(bian)、裝(zhuang)配(pei)平板(ban)(ban)(ban)易實現首尾(wei)(wei)銜接的檢(jian)測(ce)(ce)橋(qiao)板(ban)(ban)(ban)，即支(zhi)承(cheng)面(mian)長(chang)度(du)(du)B=50-60mm，寬度(du)(du)b=10mm為宜。
