Aiming at the problem on taking no account of relation of forecast factors and instability of regression results caused by selected factors with no orthonormalization which would bring out error to computational results, monadic linear regression analysis and nature orthonormalization function as well as stepwise regression were integrated to establish forecast models of cold in nanjing and upper respiratory tract infection, cerebral hemorrhage as well as cerebral infarction in jinhua
過去在選擇預報因子時沒有考慮預報因子間的相關性，挑選的預報因子由於非正交使回歸計算的結果不穩定，給計算帶來一定的誤差。針對這一問題，文章將一元線性回歸分析、自然正交函數法（ eof ）和逐步回歸方法結合起來，建立了南京感冒以及金華的上呼吸道感染、腦出血和腦梗塞的發病指數預報模型。並將模型結果與逐步回歸法建立的模型進行比較。 -
And forecast ability was compared between the models built by selecting factors as well as orthonormalization and the other models built by stepwise regression analysis directly. the comparative result was forecast ability of model by monadic linear regression analysis and nature orthonormalization function as well as stepwise regression was stronger than the models by direct stepwise regression analysis
比較得出:通過一元一次線性回歸進行因子篩選，並對其進行正交化分析，再進行逐步回歸建立的預報模型比直接利用逐步回歸分析建立的模型的預報功能強的多。 -
( 3 ) the re - orthonormalization technique is used to solve the loss of orthonormality of basis vector during the classical gmres method solving large - scale three dimensional elasto - static be problems. based on the characteristic of fundamental solution and the coefficient matrix, several precondition methods are studied. by using the technique of re - orthonoramalization and precondition, the practical gmres method is developed based on the classical one
（ 3 ）採用重正交技術解決了經典gmres方法在求解大型三維彈性靜力邊界元問題過程中出現的基向量正交性喪失的問題；結合邊界元基本解和系數矩陣的特點以及并行化的要求，研究了幾種預條件技術；並以重正交技術和預條件技術實現了經典gmres的實用化。 -
By utilizing the main advantages of orthonormalization and power conservation from hilbert transformation, it is found that bit error rate is close to that of dcsk system, but transmission speed is one time higher than that of dcsk system, and the system ' s output variance is effectively reduced
基於qpsk的思想，引入qcsk調制方式，利用hilbert變換對正交且能量守恆的特性，有效減小了系統輸出的方差，較dcsk系統，傳輸速率提高一倍，系統誤比特率與dcsk系統相近。
