We make the following assumption for when 2 is positive definite matrix, different estimators about matrix of regression coefficients and inefficiency of least squares estimate have been discussed in many documents. considered 2 is nonnegative definite matrix, this thesis derives best linear unbiased estimate of parameter matrix b and estimable parameter function kbl under the meaning of matrix nonnegative definite and the property of maximum probability of blue is investigated. next, we discuss some necessary and sufficient conditions of the equality of the lse and blue, then we derive the estimation of the deviation bet - ween the least squares and the best linear unbias estimators of the mean matrix, meanwhile a relative efficiency of lse ofb is proposed and its bound is given
當0時，眾多文獻討論了回歸系數陣的各種估計及lse的有效性，本文考慮了當0的情形，給出了回歸系數陣b及其可估參數函數kbl的在矩陣非負定意義下的最優估計（ blue ） ，研究了它的一個最大概率性質，並且討論了最小二乘估計成為最佳線性無偏估計的充分必要條件，在此基礎上給出了均值矩陣的最小二乘估計與blue的偏差估計，定義了lse相對于blue的一個相對效率，並給出了它的界。 -
Chapter 3 consider the initial - boundary value problem utt - where q is a bounded demain in rn with smooth boundary 3q ; with m ( s ) is a nonnegative c1 - function for s > 0 satisfying with we show that under certain conditions the solution blow up in finite time. chapter 4 consider the initial - boundary value problem and < ? > 2. we show the decay rate of the solutions of the equation
第三章我們考慮了定義在具有光滑邊界的有界區域上的kirchhoff型方程初邊值問題其中0 ， r ， p 1 ， q 1 ， 1 ；當s 0時， m （ s ）是空間c ~ 1中的非負函數，且滿足其中， 0 ， 2這章我們給出了上述方程解的有限時刻爆破條件。 -
A sufficient condition for the existence of a solution to robust decentralized dissipative control via state feedback and via output feedback is derived in term of a set of hamilton - jacobi - issacs ( hji ) inequalities. the sufficient condition is that the robust decentralized dissipative control problem can be resovled for all admissible uncertainties, if there exists a scaling c1 storage function such that hji inequalities have nonnegative solution. the controllers constructed make the nonlinear system robust dissipative with respect to the quadratic supply rate
基於hji不等式給出了含有不確定和干擾非線性互聯系統魯棒分散耗散控制存在的充分條件，即對于所有允許的不確定如果存在標量c ~ 1類存儲函數使得hji不等式有非負定解，那麼非線性互聯系統魯棒分散耗散控制就可獲得，並且構造的控制器使得非線性互聯系統在給定二次型供給率下具有魯棒耗散性。
