摘要
本文用投影理论及矩阵的谱分解方法，找出了推广的生长曲线模型的未知协方差 矩阵二及ｔｒ（ＣΣ）在一定条件下的不变最小二乘无偏估计，为以后更深入的研究奠定基础．
The paper reseaches the invariate least square unbaised estimate of the unknown covariance matrix Σ ad tr(CΣ) on the extension of projective theory and the pedigree decom posion of matrix, Satisfying the given condition, on the designed matrices Xi and Wi and be as a basement in further reseach.
