摘　　要：建立了封闭体内曲面型不同材料(低密度材料和高密度材料)之间的微小间隙工业CT测量方法。对多种不同材料同一积分区域进行分区积分,开发专用测量软件,测量曲面型不同材料之间的微小间隙,测量精度达到0.02mm。The accurate measurement of micro interstice between different curved materials （low density material and high density material） was constructed with industry CT. the closure. Through the subarea integration of different materials＇ same integration domain, the technial software was designed to measure the micro interstice between different materials. The measuring accuracy is 0.02mm.
