摘　　要：对自制 3组 A货翡翠、酸处理充填 B货翡翠和酸处理未充填 B货翡翠样品进行了显微硬度和抗压性分析测试。结果表明 ,A货翡翠的显微硬度远比 B货翡翠的高 ,一般在 70 0～ 1 3 0 0 kg/ mm2 之间 ,平均在1 1 0 0 kg/ mm2 左右 ;酸处理未充填 B货翡翠的硬度最小 ,一般在 2 3 0～ 672 kg/ mm2 之间 ,平均在 4 90 kg/ mm2左右 ;酸处理充填 B货翡翠的硬度介于两者之间 ,一般在 50 0～ 90 0 kg/ mm2 之间 ,平均为 750 kg/ mm2 左右。抗压性也以 A货翡翠最好 ,为 4 95～ 775MPa;酸处理充填 B货翡翠次之 ,为 3 63～ 579MPa;酸处理未充填 B货翡翠最差 ,为 2 3 1～ 2 73 MPa。Three groups of natural jadeite jade and treated jadeite jade samples are tested in microindentation hardness and compressive strength. The results show that there are great difference in durability between natural jadeite jade and treated jadeite jade. The microindentation hardness of natural jadeite jade is highest, generally 700～1300kg/mm 2, equally about 1100kg/mm 2; that of unfilled acid treated jadeite jade is lowest, generally 230～672kg/mm 2, equally about 490kg/mm 2; that of filled acid treated jadeite jade is between above two, generally 500～900kg/mm 2, equally about 750kg/mm 2.Also, the compressive strength of natural jadeite jade is highest, 495～775MPa; that of unfilled acid treated jadeite jade is lowest, 231～273 MPa; that of filled acid treated jadeite is between above two, 363～579MPa.
