The conservation law of nonholonomic system of second-order non-Chataev's type in event space is studied The Jourdain's principle in event space is presented. The invariant condition of the Jourdain's principle under infinitesimal transformation is given by introducing Jourdain's generators in event space. Then the conservation law of the system in event space is obtained under certain conditions. Finally a calculating example is given.

The authors give a proof of the convergence of the solution of the parabolic approximation towards the entropic solution of the scalar conservation law div f(x, t, u) = 0 in several space dimensions. For any initial condition uo (RN) and for alarge class of flux f, they also prove the strong converge in any space, using the notion ofentropy process solution, which is a generalization of the measure-valued solutions of Diperna.

Lie symmetry and Mei conservation law of continuum Lagrange system are studied in this paper. The equation of motion of continuum system is established by using variational principle of continuous coordinates. The invariance of the equation of motion under an infinitesimal transformation group is determined to be Lie-symmetric. The condition of obtaining Mei conservation theorem from Lie symmetry is also presented. An example is discussed for applications of the results.
