  1. It is desirable for all related insiders and outsiders to discern all potential risk in advance. this paper, with the adoption of special treatment resulted from abnormal financial position as the indicator of financial distress, the univariate variable analysis and multiple variable analysis as the research approach and some financial ratios as variable, tries to find an optimal financial distress prediction model of chinese manufacturing listed companies based on public accounting data. our finding demonstrate that five general financial ratios and three ratios concerning the cash flow have better predicting ability, the erroneous classification ratio are low. these five general financial ratios are earning per share, return on net assets, return on gross assets, growth rate of net profits, growth rate of net assets ; the three ratios concerning the cash flow are net cash flows from operating activities per share, net re - earnable cash flows / current liability, net cash flows from operating activities / net profit

    研究結果表明，在單變量分析中，每股收益、凈資產收益率、總資產報酬率、凈利潤增長率、凈資產增長率這5個財務比率的錯分率較低、預測能力較強；經營活動凈現金流量與凈利潤之比、每股經營現金流量、可重復賺取的現金凈流量與流動負債之比這三個現金流量財務比率對于預測上市公司財務困境具有有效性；多變量分析中，應用費雪判別分析和典則判別分析得到兩個判別模型，在典則判別分析中，應用兩種方法確定所建模型的最佳分界點，檢測證明應用所得兩個判別模型進行財務困境預測的準確率很高。
  2.

  3. This filter is a combination of adaptive ud decomposition kalman filter with quad method. it use quad method to detect and correct the gross errors in observations, use ud decomposition technique to improve computation precision and overcome the instability of filter caused by instability of values, when divergence of kalman filter had been detected, an adaptive filter is employed to adjust the prediction error covariance matrix

    該法用擬準檢定法準確地探測和修正量測方程中存在的粗差；用ud分解演算法改進了計算精度，克服了由於數值不穩定帶來濾波的不穩定性；當判斷濾波器發散后，則啟用sage自適應濾波器，調整預測誤差方差，以克服濾波器的發散。
