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.

本文分为三个部分，主要研究了线性互补问题的几个相关的公开问题以及猜想：(1)研究了Murthy等在[2]中提出的公开问题，即对任意的矩阵A，其扩充矩阵是否为Q_0-矩阵，给出了肯定的回答，得到充分矩阵的扩充矩阵是充分矩阵，并讨论了Graves算法，证明了若A是双对称的P_0-矩阵时，LCP可由Graves算法给出；(2)研究了Murthy等在[6]中提出关于半正定矩阵的猜想，给出了半正定矩阵的一些充分条件，并研究了Pang~-猜想，得到了只R_0-矩阵与Q-矩阵的二个等价条件，以及E_0∩Q-矩阵的一些性质；(3)研究了Danao在[25]中提出的Danao猜想，即，若A为P_0-矩阵，则，我们给出了反例证明了此猜想当n≥4时不成立，指出了Murthy等在[20]中的一些错误，得到n=2，3时，即[25]中定理3.2中A∈P_0的条件可以去掉。

Western culture in the red is a derogatory very strong word, is "fire","blood" of the association, it is a symbol of brutality, bloodshed, such as (1) The red rules oftooth and claw killing and violence, rule ,(2) red revenge bloody revenge,(3) a red battle bloody; it a symbol of radical, violent revolution, such as (1) red hotpolitical campaign heated political campaign,(2)a red revolution Red revolution,(3) red activities leftist radical activity; it is also a symbol of danger, tension, such as (1) red alert air raid alarm,(2) a red adventure story of a nerve-wrecking adventures,(3) a red flag danger signal flags; it a symbol of debauchery, obscenity, such as (1) a red waste of his youth(2) a red light district demi-monde,(3) Is she really sored as she is painted?

西方文化中的红色则是一个贬意相当强的词，是"火"、"血"的联想，它象征着残暴、流血，如（1）The red rules oftooth and claw残杀和暴力统治，（2）red revenge血腥复仇，（3）ared battle血战；它又象征激进、暴力革命，如（1）red hotpolitical campaign激烈的政治运动，（2）a red revolution 赤色革命，（3）red activities左派激进活动；它也象征危险、紧张，如（1）red alert空袭报警，（2）a red adventure story一个令人紧张的冒险故事，（3）a red flag危险信号旗；它还象征着放荡、淫秽，如（ 1）a red waste of his youth他那因放荡而浪费的青春，（2）ared light district花街柳巷，（ 3）Is she really sored as she is painted？

During the postgenomics era the information about genomic sequence and gene functions provides a new foundation for evolutionary biology and ecology As the first whole-genome sequenced plant Arabidopsis thaliana and its wild relatives have played a critical role in understanding the evolution of genomics and speciation Both A halleri and A lyrata are closely related to the model species A thaliana A halleri ssp gemmifera occurs in northeastern China Japan and Taiwan; while its sister A halleri ssp halleri is mainly distributed in Europe Geographical barriers such as Tienshan Mountain Range isolate these intraspecific sisters Likewise A lyrata ssp kamchatica and ssp lyrata occur in East Asia and North America respectively Such distribution patterns seem to be consistent with allopartic speciation The comparison between ancestral and extant polymorphism by multilocus can be informative about the population genetics of speciation In this study we collected and analyzed DNA sequences of 98 genes from four wild relatives of A thaliana A halleri ssp gemmifera A halleri ssp halleri A lyrata ssp kamchatica and A lyrata ssp lyrata The ancestral states of these four species were compared to each other in terms of level of genetic variation However the ancestral species at the time of speciation were substantially more polymorphic than the extant geographical populations The observations are not fully compatible with speciation by strict allopatry At some species pairs parapatric speciation seems more reasonable in speciation of Arabidopsis The 98 gene sequences are also used for the congruence test between gene genealogy and species phylogeny Only 28 genes support the species phylogeny but there are 23 genes supports another major genealogy { lyrata} thaliana Based on the phylogenetic position change of A lyrata ssp kamchatica and Ks value for each species pair suggested the recent directional gene flow between A halleri ssp gemmifera and A lyrata ssp kamchatica

阿拉伯芥是第一个完成基因体定序的开花植物，其基因体资讯提供植物学研究的重要依据；在解析阿拉伯芥属物种的亲缘关系以及种化机制等重要的演化议题时，阿拉伯芥近缘的野生物种自然成了不可或缺的关键；跟阿拉伯芥近缘的物种包括A halleri及A lyrata，其中A halleri ssp gemmifera主要分布於中国东北、日本以及台湾，与近缘的A halleri ssp halleri其分布於欧洲隔著天山及大陆的障蔽，而A lyrata ssp kamchatica主要分布於东北亚及台湾，与分布於北美五大湖的A lyrata ssp lyrata被北极圈所分隔，这样的分布模式暗示异域种化的可能。藉由多基因分析比较祖先物种与现生物种遗传歧异度的相关可提供讯息探讨种化时期的族群遗传结构，本研究针对A halleri ssp gemmifera、A halleri ssp halleri及A lyrata ssp kamchatica、A lyrata ssp lyrata四个物种，两对互为亚种的姊妹群，以阿拉伯芥为外群进行研究，在四个物种完成98个同源基因的分子序列，利用套装软体MCMCcoal来估算祖先物种的遗传变异，亦估算现生物种的核苷酸歧异度，观察到？多物种配对中祖先物种遗传多型性大於现生物种DNA歧异度，显示异域种化模型并无法完全解释阿拉伯芥属物种的种化模式，在某些物种配对间邻域种化模式应比异域种化更为可能；在基因树与物种树的比较，98个基因片段的亲缘模式只有28个是与已知物种树一致的，有23个基因其树状图支持{ lyrata} thaliana的型式，藉由kamchatica位置的变化以及估算各物种配对间的平均同义置换率，推测在A halleri ssp gemmifera与A lyrata ssp kamchatica间具有近代的单方向基因交流。

As a whole,the notable characteristic of primary productivity in size-fractioned structure was that nanoplankton occupied comparatively significant advantage in Beibu Gulf.Nanoplankton has the largest contribution to gross primary productivity,and picoplankton was the secondary contributor,while microplankton the least.The contribution of microplankton for primary productivity in the north Gulf was more than that in the other waters.Nanoplankton and picoplankton contribute more to the gross primary productivity in offshore deep waters than in inshore shallow waters3.The Beibu Gulf can be divided into three ecoregions:Region-Ⅰis the ecoregion in inshore shallow waters of the north Gulf.In average,the water depth is 18m,DIN is 1.88μmol/L,DIP is 0.20μmol/L,N:P is 9.4:1,dissolved silicate is 5.17μmol/L,the Chl a conentration in surface layer is 2.27mg·m~(-3),the assimilation index in surface layer is 3.80mg/,the primary productivity is 198.78mgC/(m~2·d), and potential fishery production is estimated to be 0.24gC/(m~2·a) according to the primary productivity.The ecoregion is mainly affected by the northern coastal water systems,and may be fit for aquaculture;Region-Ⅱis the ecoregion in offshore deep waters of the north Gulf and the coastal shallow waters to the west Hainan Island.In average,the water depth is 35m,DIN is 2.01μmol/L,DIP is 0.18μmol/L,N:P is 11.2:1,disovled silicate is 4.23μmol/L,the chlorophyll a of surface layer concentration is 1.45mg·m~(-3),the assimilation index of surface layer is 4.12 mg/,the primary productivity is 276.60mgC/(m~2·d),and the estimated potential fishery production is 0.34gC/(m~2·a) according to the primary productivity. The ecoregion was mainly influenced by ocean current from the South China Sea, rivers in the west coast of Hainan Island and the water from Qiongzhou Strait.It may be fit for aquaculture and fishery;Region-Ⅲis the ecoregion in offshore deep waters of the mid and south Gulf.In average,the water depth is 75m,DIN is 0.77μmol/L, DIP is 0.15μmol/L,N:P is 5.1:1,disovled silicate is 3.05μmol/L,the chlorophyll a of surface layer concentration is 0.70mg·m~(-3),the assimilation index of surface layer averaged is 3.69mg/,the primary productivity is 350.89mgC/(m~2·d),and the estimated potential fishery production is 0.43gC/(m~2·a) according to the primary productivity.The ecoregion was mainly affected by the circulation inside Beibu Gulf, and may be fit for fishery.

初级生产力的粒级结构的一个显著特点是总体上微型浮游生物在全调查海区均占较明显优势，对总初级生产力的平均贡献最大；微微型浮游生物对初级生产力的平均贡献次之；小型浮游生物对总初级生产力的平均贡献最小；湾北部小型浮游生物对初级生产力的平均贡献高于湾中部和湾南部，而湾中部和湾南部微型和微微型浮游生物对初级生产力的平均贡献高于湾北部，远岸深水区高于近岸浅水区。3、北部湾可以分为三个生态区：湾北部近岸浅水区，该区的环境主要特点是平均水深19m，DIN浓度平均值为1.88μmol/L，DIP浓度平均值为0.20μmol/L，N：P为9.4：1，硅酸盐浓度平均值为5.17μmol/L，表层叶绿素a平均值高达2.27 mg·m~(-3)，表层同化指数平均为3.80 mg/，初级生产力平均值198.78mgC/(m~2·d)，根据初级生产力计算潜在渔业资源碳生产量平均为0.24 gC/(m~2·a)，该区主要受湾北部沿岸水系影响，适合作为水产养殖区；湾北部深水区和海南岛西部沿岸浅水区，该区的环境主要特点是平均水深35m，DIN浓度平均值为2.01μmol/L，DIP浓度平均值为0.18μmol/L，N：P为11.2：1，硅酸盐浓度平均值为4.23μmol/L，表层叶绿素a平均值1.45 mg·m~(-3)，表层同化指数平均为4.12mg/，初级生产力平均值276.60 mgC/(m~2·d)，根据初级生产力计算潜在渔业资源碳生产量平均为0.34 gC/(m~2·a)，该区主要受南部湾口区海流向湾内延伸，沿岸海南岛河流注入湾内和琼州海峡过道水的影响，适合作为渔业作业区和水产养殖区；湾中部和南部远岸深水区，该区的环境主要特点是平均水深75m，DIN浓度平均值为0.77μmol/L，DIP浓度平均值为0.15μmol/L，N：P为5.1：1，硅酸盐浓度平均值为3.05μmol/L，表层叶绿素a平均值0.70 mg·m~(-3)，表层同化指数平均为3.69 mg/，初级生产力平均值350.89 mgC/(m~2·d)，根据初级生产力计算潜在渔业资源碳生产量平均为0.43 gC/(m~2·a)，该区主要受北部湾环流影响，适合作为渔业作业区。
