| Abstract: | In this article we have researched the influence of different sample temperatures against the mathematical model of NIR quantitative analysis to fat content in soybean.In order to diminish the influence, a temperature-mixed model was built,which took variable temperature factor into account in the process of modeling.The temperature-mixed model is more flexible and adaptable to different sample temperatures.The result of experiments shows that the ability to predictio of the temperature-mixed model is much better than that of the single temperature model. |
