The optimal control law obtained consists of linear analytic functions and a compensation term which is a series sum of the adjoint vectors. The analytic functions can be found by solving a Riccati matrix difference equation and a matrix difference equation. The compensation term can be obtained by a recursion formula that solves adjoint vector equations.

The estimation results show that the deferred income expense has positive relationship with earnings management, indicating that the more changes in earnings, the more possibilities that enterprise may decorate the earning level by using deferredincome tax. Additionally, the empirical result also shows that the instrument of earnings management for an enterprise usually focuses on the adjustment of recognition timing from the income and expense of the enterprise rather than the deferred income tax valuation allowances due to the temporary differences between GAAP and tax law, which is consistent with the previous studies.

实证结果发现，递延所得税费用与企业盈余管之为有显著的正向关系，表示企业盈余变动额愈大，愈可能使用递延所得税费用修饰盈余水准；实证结果同时也显示，企业真正用作为盈余管工具的部分是会计与税法规定之宽松程同而产生之暂时性差，主要从企业收入与费用认之时间点上加以调整，而非由递延所得税资产之备抵评价科目著手，此一结果则与先前之文献符合。

Furthermore, how to apply the model efficiently in practice is deeply discussed. As the variance produced by the forecasting model as concerned, the real-time revised method of hydrological forecasting is highlighted.

Later, an error selfregressive multi-stratum recursive prediction model is set up as well as a current algorithm offered. Finally, the difference collated model and the gloss control method, which are devoted to updating the mid-long term hydrological forecasting during the meditate period, are put forward.
