The following conclusions have been reached, milk has an obvious absorption in the mid-infrared band, and the locations of the absorption peak are consistent with the attributes of molecule functional group analysis and the information from FOSS Company; the effects of the factors on the repeatability are below 3‰; For the quantitative analysis, the method of factorial design is applied to optimize the calibration set. The outliers are determined considering the residual variance distribution. The correlations are 0.990 and 0.986 for fat and protein, respectively. The Root Mean of Square Error of Prediction is 0.121 and 0.111 for fat and protein, respectively. With the application of the methods of wavelengths selection, the numbers of wavelength is decreased greatly from 3301 to 100. The speed is accelerated and the accuracy of the calibration is improved to some extent.

结果表明：牛奶在中红外的吸收特性明显，吸收峰的位置与分子结构的谱带归属以及乳品分析仪器的成功厂商FOSS公司提供的资料基本一致；各种因素对光谱测量影响的CV值基本可以控制在3‰以下；在定量检测中，通过析因设计方法优选校正集样品，结合样品的残差图确定奇异点，脂肪模型和蛋白模型的相关系数分别为0.990和0.986，预测均方根误差分别为0.121和0.111，而在采用波长选择对模型进行优化后，波长从3301个减为100个以内，加快了运算的速度，同时还在一定程度上提高了模型的精度。

One was that research objects were ruleless and dishevelled. Another was that research target was reducing Ommission Error of change parcel. The Distance Discriminate Analysis was meliorated in the paper to get better recognizing effect. One was turning the question of change parcel to the question of standard land type. Another was making strict regulation. This improved Distance Discriminate Analysis is not only visual and briefness, but also easy operational.

在设计变化地块识别的判决函数时，本文针对变化地块识别工作的特殊性：1、以无规律性、无集群性的变更地块为研究对象；2、以降低变更地块的漏判率为目标，对距离判别法做了如下改良：1、将无规律、无集群性的变更地块识别问题转化为有规律、有集群性的地类识别问题；2、严格判类规则(将落入误判高发区的待测样本视为变更地块)，以减少变更地块的漏判。

Three-way data analysis (Chapter 1 to 5 of Part Ⅰ): In terms of the symmetry of trilinear model, several statistical criteria including coupled vectors resolution errors and slice-wise diagonalization error are proposed for statistically plausible resolution of trilinear data. These criteria form the basis for the development of novel trilinear analysis procedures. In Chapter 1 the coupled vectors resolution method is developed for second-order calibration.
