Abstract
In the previous report, we have dealt with the general solution of crossed partial linear difference equation which was expressed in term of stress or deformation about spaced trussed plate having infinite lattice element with simply supported edges. Now, we shall proceed our discussion with the study made on to the solution for boundry condition with four pointed supports continuous in edges by the same method mentioned in the previous report. To begin with, the very same procedures can be applied for the solution of homogeneous difference equation and then inhomogeneous difference equation af referred to in the previous article, except that we must consider the conditions of horizontal deformation, for the equation is indefinite only in case of symmetric condition when calculating equation of stress and force.
