Abstract: A glass ceramic is provided to address the challenge that bioceramics known to be used for bone defect repair often lack good hardness, proper degradability, low post-implantation stimulation to surrounding tissues and promotion of bone defect repair in combination. The glass ceramic comprises a major crystallized phase, which is either diopside or wollastonite; and a minor crystallized phase, which comprises any one or more selected from the group consisting of diopside, wollastonite, lithium disilicate, silicon dioxide, lithium metasilicate and Li2Ca2Si5O13. In the glass ceramic, the molar ratio of elemental calcium, elemental lithium and elemental silicon is 1:x:2, in which x is from 0.05 to 1. However, when the major crystallized phase is diopside, the minor crystallized phase does not comprise diopside; and when the major crystallized phase is wollastonite, the minor crystallized phase does not comprise wollastonite. The present invention also comprises a method for manufacturing the glass ceramic.

Abstract: A contour accuracy measuring system and a contour accuracy measuring method are provided. The contour accuracy measuring system captures location coordinate data of shafts of a machine tool. The location coordinate data are calculated to obtain a first true round trajectory on an inclined plane as reference information. The contour accuracy measuring system then adjusts parameters of the locations of the shafts based on the location coordinate data of the shafts of the reference information to generate a second true round trajectory on the inclined plane, so as to get to know whether the locations of the shafts after the parameters are adjusted comply with a standard. Therefore, the overall measurement process can be speeded up by automatically measuring the parameters and automatically testing an operating status.
