d＝a+(c1+c2+c3+c4-b1-b2-b3-b4)/2
d1＝a+(c1+c3-b1-b3)
d2＝a+(c2+c4-b2-b4)
wherein d represents the average inner diameter value of the cylinder sleeve to be tested; d1 represents the inner diameter of the cylinder sleeve to be tested in the X direction; d2 represents the inner diameter of the cylinder sleeve to be tested in the Y direction.
