比較長,涉及專業(yè)方面的數(shù)據(jù)我用字母代替了,見諒!以下是正文: 將上述消解液進(jìn)行適當(dāng)稀釋后按照校準(zhǔn)曲線程序加入A和B溶液,保持最終體積為50mL。 影響信號值的因素較多,主要有C、D、E、F、G、H等。本文將這6個因素采用uniform design experiment進(jìn)行優(yōu)化,選用 uniform design tabulation和相應(yīng)的use tabulation,方案是選取6個因素:C、D、E、F、G、H,每個因素選擇10個水平,試驗方案及測定信號值見下表。 對uniform design experiment選定的6個因素中,保持其他5個因素值不變,改變其中任意1個因素,在含Q的標(biāo)準(zhǔn)溶液中測定其信號值。 通過J軟件,以信號值為考察對象,采用二次項逐步回歸進(jìn)行分析,得到的二元回歸方程為:P. 從該方程的方差分析表可見,該模型顯著,預(yù)測值與實測值之間具有高度的相關(guān)性(R=K)。查F 臨界值表,得F0.05(5,4)=L ,F(xiàn)=M,回歸方程有顯著意義。上述方程的回歸系數(shù)顯著性檢驗表明:試驗6個因素中除了F、G外其他4個因素對信號值的影響皆顯著。 用J軟件求得最優(yōu)化的儀器條件見下表。 [ Last edited by qhd511 on 2011-10-8 at 12:47 ] |

Dilute the disinfection liquid properly and add it to A and B following the calibration curve program. The final solution volume is kept at 50mL. Many factors influence the values of the signal, mainly C, D, E, F, G, H, etc. In this paper the six factors is optimized by uniform design experiment, with uniform design tabulation and corresponding use tabulation. According to schedule six factors are selected: C, D, E, F, G, H, with 10 level chose from each factor. The test scheme and test signal value are listed in below chart. |

Within the six factors selected with uniform design experiment, change the value of any one factors while keeping the other five factors fixed. Test the changed factor’s signal value in standard solution Q. The signal value of the inspection object is processed through the J software, using two items stepwise regression analysis. The gotten binary regression equation is: P. From the equation’s anova table, this model is proved to be suitable. The predicted values and measured value have a high degree of correlation (R = K). Checking critical value table of F, we get F0.05 F (5, 4) = L, F = M, showing that the regression equations are meaningful (?). The regression coefficients of the equations significant test shows that within the six factors, the other four factors have significant influence on the signal value, excluding F, G. |
