Abstract: The methods of Niles p vrelid which he used in strictly pseudoconvex domains are cosulted,in  this paper,and not only for imhomogeneous Cauchy-Riemann equations on some cases that for bounded  open  sets with C'-Boundary,bounded open  sets with piecewise C¹-boundary,and peudoconvex domains with C¹-boundary are discussed,but also their linear integral operators solutions and elementary estimated  are corresponding given.
