Abstract：
The Lattice Gas Model is essentially intrduced to describe the features of isospin effect on the yield of ho particles,their ratios and double isotopic ratios. Calculations show that the multiplicity of light particles is consistent consistent the systematics of isospin. Moreover,the isotopic yield ratios are in accordance with N/Z of the system. With the increasing of (N-Z)/A, the isotopic ratios decrease,but double isotopic ratios display their insensitivity to isospin.
