通过对比四种变量选择方法，可以得到采用连续投影算法进行变量选择后，一定程度上简化了模型，并提高了模型的预测精度。

Comparing with four kinds of variable selection methods , the method of continuous projection algorithm variable selection could enhance quantitative spectral calibration model prediction accuracy and modeling efficiency and the NIR calibration models with good predictive ability and stability could also be acquired .

同时基于这些模拟值，参考CE理论和Heyes关系式，以对比温度、对比密度以及对比孔径为变量，关联出两个简单流体等摩尔混合物在微孔中扩散系数的计算模型。

Based on the Chapman-Enskog theory and Heyes equations , two correlation models , which can describe the diffusivity of simple fluid mixtures in porous media , are proposed as functions of the reduced temperature , density and pore width .
