 By means of Fourier transform, the solution has been obtained in the form of a double integral and this in turn has been approximated by the saddle point method for a geometrical picture. The bottom is represented in integral form using Fourier's double integral theorem. In previous versions of this technique, the characteristic function of the MAI component of the decision statistic was expressed in terms of a double integral over the distributions of phase and delay. The elastic scattering amplitude of a scalar particle in an arbitrary plane wave electromagnetic field is obtained in the form of a double integral by the method of dispersion relations. The double integral representing the entropy Stri of spanning trees on a large triangular lattice is evaluated using two different methods, one algebraic and one graphical. 更多 To find the sectionally holomorphic veclor ■(P)≡(φ_0,φ_1,φ~2,φ~3):1) Which is holomorphic in D~+ and D~-, i.e. satisfying the system of partial differential equations of elliptic-type of the first order in spaceand satisfying on the boundary surface ∑ the boundary condition(H)_l ■~+(P_0)=G(p_0)■~-(p_0)+■(P_0)Where G(p_0)=[G_(ij)(p_0)],ij=1,2,3,4, which is a given nonsingular function matrix on ∑ and (?)(P_0)=(g_1,g_2,g_3,g_4) is a given function vector and they are satisfying the H (Hlder) condition on ∑.

The RQCS code is designed to supply multigroup constants for thermal neutron reactors. It deals with a flexible input format of differential nuclear data which is similar to but somewhat simpler than that applied in ENDF/B library. There are thirteen types of group averaged cross sections as output constants, including elastic transfer cross sections.Each element of the high order transfer matrices of elastic scattering results from a double integral, its inner integral is given by R_ι(E,μ_1,μ_2)=integral from μ_1 to μ_2 P_ι(μ)P(μ,E)dμ. It is the oscillation property of Legendre function in the integrand that makes the calculation of elastic matrices the most timeconsnmming work in the whole calculation, particularly when the order 1 gets higher (1=8 for example). In the early stage of our work, we studied the method proposed in MIGROS-3 (KFK-2388), but we found the calculation speed of this method was too low to make the method practicable for 1=8 when using a medium computer, therefore we propose a new method, in which the inner integral may be obtained by interpolation and simple algebraic operation. The calculation speed of this method is faster than that of the KFK method.
