Kunio Hidano[4] has shown that the global and local C2-solutions for semilinear wave equations with spherical symmetry in three space dimensions.This paper studies the global and local C2-solutions for the semilinear wave equations without spherical symmetry in three space dimensions.A problem put forward by Hiroyuki Takamura[2] is partially answered.
