(11) By using � �S x y, # � from equation (8) we obtain C1 0$ � �C These can be mathematically described by the composition of the deterministic and random components of irregularities in the given Cartesian coordinate system: � � � � � �h x y S x y x y, , ,� � � (1) where S(x, y) is the deterministic function of the surface (x, y) coordinates and �(x, y) is the homogeneous random normal field.	cache/ap-328.pdf	txt/ap-328.txt
