  2. The use of wave packet to analyze the dynamics of quantum mechanical systems is an increasingly important method to the study of the classical - quantum correspondence. using the quantum gaussian wave packet analysis method, we calculate the autocorrelation function of the rectangular billiard, the peak positions of the autocorrelation function match well with the periods of the classical periodic orbits, which show that the period of the classical orbits can be produced by the time - dependent quantum wave packet method. we also discuss wave packet revivals and fractional revivals in the rectangular billiard, the results show that there are exact revival for all wave packet at each revival time. we find additional cases of exact revivals with short revival times for zero - momentum wave packets initially located at special symmetry point inside the billiard

    利用波包分析量子力學體系的動力學行為在研究經典和量子的對應關系方面越來越成為一個非常重要的方法.利用高斯波包分析方法，我們計算了矩形彈子球體系的自關聯函數，自關聯函數的峰和經典周期軌道的周期符合的很好，這表明經典周期軌道的周期可以通過含時的量子波包方法產生.我們還討論了矩形彈子球的波包回歸和波包的部分回歸，計算結果表明在每一個回歸時間，波包出現精確的回歸.對于動量為零的波包，初始位置在彈子球內部的特殊對稱點處，出現一些時間比較短的附加的回歸
  3. Thirdly, the short - term and long - term financial early - warning system is established based on the financial statements of marketing corporation in electric power, medicine and general merchandise. systematic method, efficiency coefficient method and linear regression method are applied in the short - term financial early - warning system from the aspect of cash flow, operating performance and function model ; growth periods method and management grade method are applied in the long - term financial earl y - warning system from the aspect of growing capability and financial stratagem. finally, lots of examples are given to validate these early - warning models, and some countermeasures are discussed for avoiding and eliminating the distress of enterprise

    首先，介紹了企業財務預警的概念、功能和國內外的研究現狀；其次，闡明了企業財務預警的原理、程序和方法；再次，它以電力、醫藥和百貨行業的上市公司報表為資料，按照指標選取、標準判斷、警限設置和警度預報的步驟，從企業的現金流量、財務業績和函數模型三方面，分別運用系統化方法、功效系數法和線性回歸法構建了企業短期財務預警系統，從企業的成長能力和財務戰略兩方面，分別運用周期波動法和管理評分法構建了企業長期財務預警系統；最後，舉了大量實例對構建的各個預警模型進行考證，並從財務角度探討了企業的防警和排警對策。
