Crystal lattice constants are close to other experiment results. Three kinds of chemical bonds exist among Mg and B atoms, between magnesium and boride is ionic bond and metallic bond is the predominant interaction in the layer formed by magnesium atoms. A strong covalent bond in the form of sp2 hybrid between boride atoms is the most important factors which can affect the transition temperature of MgB2. Population analysis clearly shows that electrons are transferred from Mg to B, as a result, the electron-phonon coupling in the layer of B is very strong.

When it comes to the local prediction of chaotic time series, owing to the fact that the fixed embedding dimension、the number of the nearest neighbours and regularization parameters can cause the added prediction error,we give the adaptive local linear method and discuss the adaptive selection method of regularization parameters, the advantage of which is tested by the Henon map and Lorenz system simulated data and the integrated index in stock market of Shanghai, to show its practicable value.
