术语“线性判别函数”的详细信息

英译术语:

linear discriminant function

汉语语境:

将距离判别分析法应用于岩体质量等级分类问题中，建立岩体质量等级分类的距离判别分析模型，选用单轴抗压强度、岩体声波纵波速度、体积节理数、节理面粗糙度系数、节理面风化变异系数和透水性系数6项指标作为距离判别分析模型的判别因子，以工程岩体实测数据作为学习样本进行训练，建立相应线性判别函数对待判样本进行分类。

英语语境:

Based on the principle of Mahalanobis distance discriminant analysis, a classification model of engineering quality of rock masses is established, including six indexes reflecting the engineering quality of rock masses:uniaxial compressive strength, P-wave velocity in rock, volumetric joint countr, oughness coefficients of joints, weathering coefficients and permeability coefficient of joints. Linear discriminant functions are obtained through training a large set of expansive samples.
