Abstract: Defined are bilateral and lower side bitangent Laplaec-Stieltjes transform and integral.Discussed are three pairs of dependent converge abscissa of this series.By introducing a seguently decreasing negative real series｛λ(-m)｝and｛μ(-n)｝,the θ linear order and lower order concept and existing theorem in analytic function defined by lower side Laplace-Stieltjes integral are established.The growht theory of the integral in bilinear strip is also established,extending the corresponding results of upper side bitangent Dirichlet series.

Key words: lower side bitangent Laplace-Stieltjes transform； binary in analytic function； abscissa of dependent absolute converge； θ　linear order； θ linear lower order； bilinear strip；
