The conclusions on the invariant set deduced in last chapter are applied to this model. although some results are deduced with the aid of computer computing, we stil1 regard it is rigorous because of the nonempty of the regions we obtained. the following numerical simulations further reinforce our results
並通過計算機數值計算論證了我們給出摘要的具體參數范圍並非空集；爾后，我們還將第二章中得到的不變集的性質運用於該時間映射之中；最後，我們給出了相應的數值模擬以進一步說明理論證明的有效性和正確性 -

Numerical result shows that the new method is more efficient in convergence than the standard lanczos algorithm ; the second algorithm generalizes the implicitly restarted arnoldi ( ira ) augmented by soreesen to the implicitly restarted lanczos algorithm, which improves the convergence rate of lanczos algorithm by making good use of the spectral information obtained from the previous process. the last algorithm utilizes deflation strategies to the second algorithm to forming invariant subspace for a, so that the stability can be kept in computing process
數值試驗表明，該演算法比標準lanczos方法具有更好的收斂性；第二種演算法是將求解特徵值問題的隱式循環arnoldi方法（ ira ）應用於求解對稱不定線性方程組的lanczos演算法，充分利用lanczos演算法過程中的譜信息，確定預處理；第三種演算法是在第二種演算法的基礎上，運用收縮技巧，形成近似不變子空間，以提高收斂速度和數值穩定性。 -
Finally, the effectiveness of the proposed method is verified through theoretical and numerical results for systems with both unknown time - invariant and time - varying parameters
理論分析與模擬結果表明，跟蹤誤差信號在一預先指定區間上收斂到零，在起始區間段上被囿於死區所確定的區域中；並保證閉環系統中所有信號是有界的。 -
