  1. The flood and drought in both first stage and second stage of rainy season in fujian province were forecasted by the ways of line regression prediction equation and three kinds of artificial neural network models, the results show : the backpropagation ( bp ), radial basis function ( rbf ) and elman neural network models are much better than line regression prediction equation in historical sample fittings, independent sample test, actual prediction ability

    （ 3 ）運用線性回歸預報方程和三種人工神經網路模型對福建汛期旱澇進行預測的實驗表明： bp 、徑向基（ rbf ）和elman這三種人工神經網路模型在歷史樣本擬合精度上、獨立樣本檢驗結果和網路模型的實際預測能力上都明顯優于傳統的線性回歸方法。
  2. Technology of non - damage test for concrete intensity is extensively applied in project testing, as a precise and direct approach. accordingly, the test in this essay makes use of average concrete samples made up of commo - n raw material in boutou, and adopt comprehensive method of ultrasonic elasticity to test the concrete used within one year in boutou. through the regression analysis, we get the regression equation of anti - intensity of these two materials under the given conditions. according to the result, we establish the accurate curve line for comprehensive method of ultrasonic elasticity and provide practiced and non - damage testing approach and calculating method for concrete intensity test and reference for testing staff concerned

    混凝土強度無損檢測技術作為一種簡便快捷準確的測強技術在工程檢測中得到了廣泛的應用，鑒於此，本次試驗通過採用包頭地區常見原材料製成的一定批量常見齡期的不同種類（指混凝土試塊中的粗骨料、混凝土強度等級不同）普通混凝土標準試塊，採用回彈?超聲綜合法對包頭地區齡期不超過一年的現場混凝土進行了大量的試驗，並利用回歸分析，給出兩種骨料混凝土在相應測強條件下的立方體抗壓強度回歸方程，根據實驗結果建立包頭地區精度較高的混凝土回彈?超聲綜合法基準測強曲線，為實際工程的混凝土現有強度評定提供簡單易行的無損測試方法和計算方法，供有關檢測人員參考使用。
  3. This paper use experimental data to set up linear regression equation with unitary and regression straight line, to use variance analysis and related coefficient to test validity of equation

    摘要本文利用實驗數據建立一元線性回歸方程；回歸直線，並用方差分析法和相關系數法檢驗方程的有效性。
  4. The following conclusions were reached : i ) in different watershed, runoff depth and sediment transport modulus have power function ( y = axb ) relationship and the non - line regression equation can well simulate their relationship. parameter a and b can reflect difference of watershed harness degree

    通過研究，取得如下結論： （ 1 ）在不同流域內，徑流深與輸沙模數均成冪函數（ y = ax ~ b ）關系，其關系方程以非線性回歸擬合結果比較好。
  5. To prove the applicability of respective regression equation, the essay adopt regression analysis to test the accordance of samples and find the testing report accords with the predicating one. to test the applicability and practical usage of the intensity curved line in boutou, we test the concrete items on site, and compare it with standard curved line in my country, and the consequence shows that : the intensity curved line of the comprehensive method of ultrasonic elasticity has high applicability and accuracy

    為了更好的檢驗回歸所得到的超聲回彈綜合法測強曲線方程在包頭地區的適用性和實用性，我們特地進行了工程現場混凝土構件強度的檢測試驗，並且和全國的基準曲線方程相比較，得到的數據顯示：我們由試驗得到的超聲回彈綜合法測強曲線方程在包頭地區有很好的實用性和適用性，精度相對較高。
