In recent years, with the rapid introduction and commercialization of lchinense vai. rubrum, there comes many confusion concerning the identity of cultivars. in this study, the morphological traits of 21 accessions of lchinense var. rubrum were investigated in spring, autumn, summer and with 2 more accessions in autumn. clustering analysis with average distance was processed for the main traits of leaf and flower using dps ( data processing system )
本文對紅?木的21個變異類型作了春、夏、秋三季形態調查（秋季又增加了2個類型） ，對葉、花的有關性狀如葉色、葉長寬比、花色、花瓣長寬比、小花數、花瓣數進行了聚類分析。 -
With respect to genetic similarity, genetic distance and cluster analysis among samples of f1 generation, it showed that the most genetic identity is between jfp and jmp, ( i = 0. 9934, dnei = 0. 0066 ), the next was between jp and jmp ( i = 0. 9873, dnei = 0. 0128 ), the third was jp and jfp, with i = 0. 9681, dnei = 0. 0325 ; the fourth was jp and cp, with i = 0. 9035, dnei = 0. 1015 ; the fifth was cp and jmp, with i = 0. 8862, dnei = 0. 1208, and the furthest was between cp and jfp, with i = 0. 8648, dnei = 0. 1452
由此可以看出在此四組中，雜交組的遺傳變異明顯高於自交組的，雜種優勢已初步顯示出來。而在兩雜交組中，日雄中雌雜交組又優于日雌中雄組中自交組。群體間遺傳相似系數和遺傳距離及聚類分析結果表明：兩雜交組間的遺傳相似系數最大，遺傳距離最小，僅為0 . 0066 ，而中自交組群體與日雌中雄雜交組群體的遺傳距離最大為0 . 1452 ，兩自交組群體間的遺傳相似系數為0 . 9035 ，遺傳距離為0 . 1015 。 -
It comes up with a new notion, d - solution, which is applied to the distance estimation, by virtue of hilbert space ; furthermore, the dissertation has gained a necessary condition which is identity of minimum mean - square value in linear function classes, so that d - solution extends minimum mean - square value within the domain of nonlinear function equation or equation system ; and, the dissertation studies in detail the classical moment estimation and maximal likelihood estimation on the parameters of ar ( p ), a series of theorems in the estimation section shows the moment estimators are consistent on the ground of large samples jikewise, those distribution functions of the estimated parameters accord to maximum likelihood estimation converge gauss distribution if the white noise is gaussan
首先，藉助hilbert空間理論，提出了距離估計的d -解，給出了d -解的必要條件，這個條件在線性函數類里即是極小二乘估計法， d -解的必要條件滿足的方程實質上將極小二乘估計法推廣到多函數及非線性函數類。再而，詳細地研究了多元弱平穩序列自回歸模型ar （ p ）的參數經典的矩的替代估計和極大似然估計，獲得矩的替代估計的一致性的結果。對基於gauss白噪聲假設多元弱平穩序列自回歸模型的均值、白噪聲的協方差陣的極大似然估計都有依分佈收斂到多元正態分佈的統計性質。 -
