A part of a surface like kappa alpha lambda, which forms a circle, appears in the process of drilling. The surface absorption of ETAThere are four surfaces of a kappa alpha lambda(1A), one surface of a first surface, one surface of a second surface (11) (12) (13), and the third and fourth surfaces. (14)This allows the absorption of the surface absorption in the handling process, as well as on a Thursday surface (15).This is a mansion with a circular section (15a) formed on the surface and a perforated sixth surface (16) produced by the treatment. On Thursday, I told the surface (15).The perforation takes place in the direction (a) shown by the arrow to make the first surface, the second surface (11) (12),The surface of third and fourth surfaces (13) (14) forms surface shear.Therefore, the outer surface (15) of the four blocks kappa alpha lambda(1A) last Thursday forms a circular part (15a), and the sixth one. Surface (16);Towards the surface (15) of the Thursday, the formation of the surface can form a prescribed dimensional accuracy, and any. Among them, the first surface (11)Second surface (12).The surface of the third and fourth surfaces (13) (14) can provide a surface absorbed by such a surface (15) in which___gamma was formed last Thursday. 15AAbsorption is the core of the surface.
