山東00級大理石方規的(de)物理性(xing)穩(wen)定 組織縝密(mi) 受撞擊晶(jing)粒脫落(luo) 表面不(bu)(bu)起(qi)毛邊 不(bu)(bu)影響其(qi)平面精度，能夠保證長(chang)期不(bu)(bu)變形，線(xian)膨(peng)脹系數小，適用于工業生產中的(de)垂直測量。

保留平(ping)行(xing)度(du)和垂直度(du)檢驗的功用(yong)，大(da)理石方尺是一(yi)種方形的大(da)理石檢具(ju)。比較罕見的一(yi)種類型，分歧的時分，并(bing)不是是角度(du)的檢驗和加(jia)工(gong)(gong)工(gong)(gong)具(ju)，次要(yao)是丈(zhang)量，檢驗或許是加(jia)工(gong)(gong)石材共(gong)建(jian)的平(ping)行(xing)成(cheng)效(xiao)，以達成(cheng)各(ge)個工(gong)(gong)件(jian)的完整平(ping)行(xing)度(du)。正是因為如斯，眾多石材工(gong)(gong)件(jian)中，都有(you)著一(yi)定(ding)的專業性(xing)使用(yong)效(xiao)果(guo)。
