本文首先利用Ｏ．Ｓｔｏｌｚ定理证明了自然数的方幂和能够化为多项式。在此基础上，给出了一个化自然数的方幂和为多项式的简便且直观的方法。     

The innovation research of financial early-warning index measurement

The period economic fluctuation is vital for an enterprise to exist and further develop,it directly affect the enterprise financial health.So,it is significant to build up financial early-warning index and measure the warning condition that the enterprise faces and take the effective measures to eliminate. We criticize Altman's Z calculating model and build up some new indexes for enterprise financial early-warning condition measuring and making sound decision.

Pattern formation in Rayleigh-Bénard convection: Numerical simulation with a coupled-map-lattice model

The various patterns formed in Rayleigh-Bénard convection under different conditions are numerically simulated with a coupled-map-lattice model. In the case of a lower aspect ratio (L/d=5), the simulations vividly depicted the main features of the transition process from a laminar state to a soft turbulence and then to a hard turbulence. In this case, the cellular structure in a horizontal section is also reproduced. In the case of a larger aspect ratio (L/d=30), the simulations successfully reproduced the spiral-defect chaos and target chaos in the initial stage of the pattern evolution which were recently found in experiments. In this case, for a fluid ofPr=1, it is verified in simulations that both the ideal straight rolls and spiral-defect chaos are stable attractors in the same parameter regime, and that the initial condition is a decisive factor for which one of the two is formed. In the same case, for a fluid ofPr=4, the target patterns are dominant instead of the spirals, the sizes and distributions of the target are also notably dependent on the initial condition.
