AB - In this paper, we prove that under some conditions, A two-dimension vectorial Sturm-Liouville Problem can only have finitely many eigenvalues of multiplicity two. Using this result, we imply that the spectral of two Sturm-Liouville Problem of dimension one , or two string equation, have finitely many ,such that the eigenvalues of the elements in common. And then we find a bound
