<p><P>PROBLEM TO BE SOLVED: To provide a decision method for the homogeneity of a sphere in which the homogeneity is decided by taking into account a deviation amount of the sphere center between respective spherical layer bodies. <P>SOLUTION: When coordinates of the sphere center Ga of a spherical layer body Sa on the outermost layer of the sphere S are used as the origin, X- coordinates of the sphere center Gm of a spherical layer body Sm as an m-th body as counted from the spherical layer body Sa in the outermost layer are designated as x<SB>m</SB>, Y-coordinates are designated as y<SB>m</SB>, Z-coordinates are designated as z<SB>m</SB>, X-coordinates of the sphere center Gn of a spherical layer body Sn as an n-th body are designated as x<SB>n</SB>, Y-coordinates are designated as y<SB>n</SB>, and Z-coordinates are designated as z<SB>n</SB>. The deviation amount A (A=[(x<SB>n</SB>-x<SB>m</SB>)<SP>2</SP>+(y<SB>n</SB>-y<SB>m</SB>)<SP>2</SP>+(z<SB>n</SB>-z<SB>m</SB>)<SP>2</SP>]<SB>1/2</SB>) of the center between the spherical layer bodies Sa and Sb as two layers, that of the center between the spherical layer bodies Sb and Sc as two layers and that of the center between the spherical layer bodies Sc and Sa as two layers are calculated by the following expression so as to decide the homogeneity of the sphere S. <P>COPYRIGHT: (C)2003,JPO</p> |
