Through transformations, the time-dependent boundary condition on the airfoil contour and the boundary condition at infinity are brought fixed to the boundaries of a finite domain. The boundary conditions can thus be satisfied exactly without increasing the computational time. The novel scheme is useful for computing transonic, strong disturbance, unsteady flows with high reduced frequencies. The scheme makes use of curvefitted orthogonal meshes and the lattice control technique to obtain the optimal grid distribution. The numerical results are satisfactory.

Similar to Blasone et al.[Phys.Rev.D 72(2005)013003]by examining the expectation value of the flavor charge under the normalized flavor state of the neutrino,we demonstrate that the introduction of the flavor state is consistent with the flavor charge only when the conditions,i.e.(A)|p|=0(the low energy case),or|p|/mi≫1(the relativistic case)and(B)the flavor state should be defined of the Pontecorvo form|νe〉=cosθ|ν1〉+sinθ|ν2〉or equivalently except a global phase,are satisfied.The root of the issue lies in the structure of the flavor charge operator.The diagonalization of the flavor charge operator with the integer eigenvalue can be realized through the Bogoliubov–Valatin transformation when condition A is satisfied.The eigenstate of the diagonalized flavor charge is of the Pontecorvo form under condition B.

This paper considers the system where with where provided orThe traveling wave solution of problem （A）, （B） is proved to be asymptoically stable when （C）1, （C）2 are satisfied and rarefaction wave solution is proved to be asymptotical when （C）3, （C）4 are satisfied, provided that the initial disturbance is suitably small and of zero constant component. The proof is given by the elemental L2 energy method.

Recently Lax operator algebras of many known integrable systems in 1 + 1 dimensions have been presented by direct computation. The aim of this letter is to give a systematic description for Lax operator algebras of integrable systems. In accordance with Ref. [ 4], let B denote all complex （or real）C∞-differentiable functions P[u] = P（x, t, u）, Br={(P1,…,
