In this thesis, we study some open problems and conjectures about the linear complementarity problem. it consists of the next three aspects : firstly, we study murthys " open problem whether the augmented matrix is a q0 - matrix for an arbitary square matrix a, provide an affirmable answer to this problem, obtain the augmented matrix of a sufficient matrix is a sufficient matrix and prove the graves algorithm can be used to solve linear complementarity problem with bisymmetry po - matrices ; secondly, we study murthys " conjecture about positive semidefinite matrices and provide some sufficient conditions such that a matrix is a positive semidefinite matrix, we also study pang ' s conjecture, obtain two conditions when r0 - matrices and q - matrices are equivelent and some properties about e0 q - matrices ; lastly, we give a counterexample to prove danao ' s conjecture that if a is a po - matrix, a e " a p1 * is false, point out some mistakes of murthys in [ 20 ], obtain when n = 2 or 3, a e " a p1 *, i. e. the condition of theorem 3. 2 of [ 25 ] that a p0 can be deleted and obtain a e " a is an almost e - matrix if a is a co - matrix or column sufficient matrix
本文分為三個部分,主要研究了線性互補問題的幾個相關的公開問題以及猜想: ( 1 )研究了murthy等在[ 2 ]中
提出的公開問題,即對任意的矩陣a ,其擴充矩陣是否為q _ 0 -矩陣,給出了肯定的
回答,得到充分矩陣的擴充矩陣是充分矩陣,並討論了graves演算法,證明了若a是雙對稱的p _ 0 -矩陣時, lcp ( q , a )可由graves演算法給出; ( 2 )研究了murthy等在[ 6 ]中
提出關於半正定矩陣的猜想,給出了半正定矩陣的一些充分條件,並研究了pang ~ -猜想,得到了只r _ 0 -矩陣與q -矩陣的二個等價條件,以及e _ 0 q -矩陣的一些性質; ( 3 )研究了danao在[ 25 ]中
提出的danao猜想,即,若a為p _ 0 -矩陣,則,我們給出了反例證明了此猜想當n 4時不成立,指出了murthy等在[ 20 ]中的一些錯誤,得到n = 2 , 3時,即[ 25 ]中定理3 . 2中a p _ 0的條件可以去掉。
The afterheat, which is collected by recovery devices, in winter can be used as the low level thermal source of heat pump, and in summer can preheat feed water, thus equivalent an economizer. because energy flows in the system so reasonably that energy is used to the most, therefore, its energy conservation effect is significant, and the operating expenditure declines consequently. the sewage can be reused after due treatment, thua it has a certain social and ecological benefit, too
本研究中選用分離式熱管裝置
提供洗浴用水,利用水源熱泵裝置,一機兩用,進行空間供熱和製冷,並通過余熱
回收器對系統內的余熱進行
回收,冬季可作為水源熱泵的低位熱源,夏季可對鍋爐給水進行預熱,起到「省煤器」的作用。這樣實現系統內的能量合理流動,從而達到節能的目的,同時洗浴污水經適當的處理后可以
回用,因而還具有一定的社會和生態效益。
Newcastle disease virus ( ndv ) strain 695, a thermostable nature avirulent strain, were replicated in embryonated chicken eggsand its rna was extracted from allantoic fluid. referred to the reported sequence of f gene, a pair of primers were designed and synthesized. f gene of ndv b95 strain was amplified by rt - pcr, the pcr products were checked by agrose gel electrophoresis and purified by agrose gel fracion method

提取病毒的基因組rna ,參考國內外發表的ndv融合蛋白基因序列,設計一對特異性引物,經反轉錄聚合酶鏈式反應( rt - pcr )擴增出約1700bp大小的特異性片段,將此片段
回收純化后,利用t - a克隆技術將其克隆到pgem - t - easy克隆載體中,再轉化大腸桿菌jm109感受態細胞,轉化后經分子量比較、 pcr鑒定和酶切分析篩選陽性克隆。
