The results demonstrate that: ARMA(1,1) model,auto-regressive model with GDP as exogenous variable,auto-regressive model with policy as exogenous dummy variable,and logarithm linearity and removal average model are all valid models for forecasting tax revenue.

结果表明：ARMA(1，1)模型中，以GDP为外生变量的自回归模型、以政策因素为虚拟外生变量的自回归模型以及对数线性移动平均模型都是预测税收收入的有效模型，但以GDP为外生变量的自回归模型在预测2005年税收收入时，预测值与实际值的预测偏差仅有1。

In Kubuqi sandland of Erdos plateau, from 1991 to 1996, we collected the datum of 42 months about three-toed jerboa,dersert hamster, Chinese jird, striped hamster,five-toed jerboa, and ground squirrel, and we focused to describe their seasonality, inter annual change and trends by moving average and analysis of PCA.

Firstly, two covering hypersphere algorithms were proposed, referred to as minimum volume covering hypersphere algorithm and moving medium centers covering hypersphere algorithm, to heuristically and rapidly select the promising hidden center vectors from all the training samples. Then the particle swarm optimization algorithm combined with recursive orthogonal least square algorithm was used to further prune the initial hidden centers and optimize the control parameters.

为在实际应用中加速优化速度，降低优化计算复杂度，首先提出了最小体积覆盖超球和移动平均中心覆盖超球两种算法，用于启发式的从训练样本中快速的初选出径向基概率神经网络的隐中心矢量，然后将粒子群优化算法和 ROLSA 结合进一步优选隐中心矢量，同时优化核函数控制参数，实现径向基概率神经网络的全结构优化。
