From mathematical models for inverse scattering in two dimensional inho - mogenous media including variable impedance, all kinds of probable mixed variable impedance boundaries and cracks, from interior and exterior trans - mission problems and radiation condition, ill - posed integral equation and indicator function method are formulated for the diverse of boundary iden - tification. it is shown that the kernel of the integral equation characters the boundary of scatterer, which is determined by solving it by virtual of regularity method, meanwhile, some numerical tests are given. 3
在二維非均勻介質逆散射邊界識別的數學模型（包括一般的非均勻介質，正交各向異性介質，變阻抗介質，各種可能的混合變阻抗邊界問題）下，由內透射問題和外透射問題以及輻射條件，推導了上述介質的邊界識別的積分方程和指示函數方法，由於積分方程的核充分表徵了散射物的邊界，由此說明只要利用正則化方法求解該積分方程，就可以確定散射物的邊界。 -
Time series methods are especially good for short - term forecasting where, within reason, the past behaviour of a particular variable is a good indicator of its future behaviour, at least in the short - term
時間序列法特別適合短期預測，原因之一是一個特定變量的可以由先前的屬性推斷出未來屬性，至少短期可以。 -
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。 -

In upscaling, to generate an unbiased aggregation of a sparsely sampled variable from an uneven environment, use a richly sampled indicator that covaries with the variable of interest ( a scalar ) to create a weighted average
尺度上推時，要從不規則的環境中建立分散取樣變量的無偏集合，就利用與影響變量（標量）共變的已充分取樣的指標得到加權平均值。
