The development of credit unions is highly associated with effective legal *** legal content must be consistent with the inherent law of credit *** and regulations control the credit union system and help keep them on a smooth and healthy *** article is trying to reveal the legislative history and status of credit unions on the Chinese mainland and *** compares how to maintain fairness and efficiency during reforms of credit unions across the strait in order to give reference to and complement each other and produce new ideas for the development in the future.

An accurate three-dimensional potential energy surface(PES) for the He-Na2 van der Waals comple was calculated at the coupled cluster singles-and-doubles with noniterative inclusion of connecte triple(CCSD(T)) level of theory.A mixed basis set,aug-cc-pVQZ for the He atom and cc-pCVQZ for th sodium atom,and an additional(3s3p2d1f) set of midbond functions were *** computed inte action energies in 819 configurations were fitted to a 96-parameter analytic potential model by leas squares *** PES has two shallow wells corresponding to the T-shaped structure and the linea configuration,which are located at 12.5a0 and 14 a0 with depths of 1.769 and 1.684 cm-1,respectivel The whole potential energy surface exhibits weak *** on the fitted PES,state-to-stat differential cross sections were calculated.

For the discrete dynamical system on the nonnegative orthant generated bya cooperative and concave map T, we present an algebraic criterion of its asymptoticbehavior. The global behavior of such a system is completely determined by the sign of allprincipal minors of the matrix I-DT(0). This criterion applies to the cooperative systemwhich is concave, time-dependent and periodic in t. We give the sufficient conditions thatthe zero solution of such a system is globally asymptotically stable and that it possesses anonzero periodic solution which attracts all initial conditions in the nonnegative *** at the origin. The results of Smith under weaker conditions and some applicationsare included.
