Firstly, we give a necessary and sufficient condition for a nonnegative square matrix to be decomposed into a product of a finite number of irreducible nonnegative matrices in chapter 1. We prove it by using Frobenius normal form in combinational matrix theory and associated directed graph in graph theory. In addition, we can limit the number of factors to three, and construct every factor.

首先，在第一章中，我们给出了一个非负矩阵可以分解成有限多个不可约非负阵的乘积的充要条件，证明过程利用了组合矩阵论中的Frobenius标准型和图论中的伴随有向图，并且将乘积中的因子个数限制到三个，具体地构造出了分解式中的每个不可约非负阵。

Culture tender leaves in culture medium of MS+2,4-D1.5mg/L+30g/L suger+0.7% agar pH5.8 for 20 days in darkness at 25℃, and then subculture to induced Ⅱ-type calli. Use forceps cutting the tissue to nubble with 2mm2, and put the tissue into Agrodacterium tumefaciens LBA4404 liquid supplemented with AS 100mg/L,then, co-culture 3 days, resume 7 days in MS+2,4-D1.5mg/L+30g/L suger+500mg/L cef, take to MS+2,4-D1.5mg/L+30g/L suger+100mg/L cef+10.0mg/L kanamycin culture 20 days in darkness. After that to make it polarize in MS+30g/L suger+100mg/L cef+10.0mg/L km. The percentage of km resistant callus was reached max after infection for 45 min, the average is 29.66%. Simultaneity, tender leave callus are infected 5 min by A. tumefaciens liquid in different negative pressure, and kept on 15 min in Agrodacterium tumefaciens liquid without negative pressure. Then screen out resistant callus and obtain transgenic plants. When the negative pressure is -0.05MP the percentage of km resistant callus was reached max, the average rate is 37.5%.

将心叶接种于MS+2.4-D1.5mg/L+30g/L 蔗糖，琼脂0.7%，pH5.8 培养基中25℃暗培养20d 后继代一次，诱导产生Ⅱ型胚性愈伤组织，用镊子将其夹碎成2mm2大小的小块，置入添加100mg/L AS 的根癌农杆菌LBA4404 菌液中，侵染时间为45min，共培养3 天后，转入MS+2.4-D1.5mg/L+30g/L 蔗糖+500mg/L Cef 培养基中恢复7天，再转入MS+2.4-D1.5mg/L+30g/L 蔗糖+100mg/L Cef+10.0mg/L Km 中，遮光培养20d后，置入其MS+30g/L 蔗糖+100mg/L Cef+10.0mg/L Km 分化，卡那霉素抗性愈伤组织获得率在侵染45min 时达到最大值平均为29.66%；同时以甘蔗心叶愈伤组织材料，通过循环水式真空泵，产生负压，设定不同的负压值，在农杆菌菌液中感染5min 后，在负压条件下继续侵染15min 后，筛选出抗性愈伤组织并获得转化植株，其中在负压为-0.05 时转化率达到最大值，其卡那霉素抗性愈伤组织获得率平均为37.5%。

There are bands of Triticum and Elytrigia in Tritielytrigia, they are new octoploid types that be different from Triticum and Elytrigia.

小偃麦兼有小麦和天蓝偃麦草的酶带，是不同于小麦和天蓝偃麦草的八倍体新类型。5个小偃麦划分成两种不同的类型，中_1和中_2属于第一种类型，中_3、中_4和中_5属于第二种类型。

It was proved that the genomes from E. intermedia may be different between six octoploid Trititrigia and another five 8x Trititrigia Zhong1, Zhong2, Zhong3, Zhong4 and Zhong5 acquired by other breeder.

综合种子醇溶蛋白电泳和细胞学分析结果，初步认为本研究选育的6个八倍体小愝麦与前人选育的中1、中2、中3、中4、中5等5个八倍体小偃麦所携带的中间偃麦草染色体组可能不完全相同。

With Hilbert space filling curve and latent semantic index, MLSQ maps similar data objects in high dimension semantic space into an adjacent range in one dimensional value space, and considers every data object sequence number in one dimensional space as a key. MLSQ distributes the keys to adjacent nodes of structured P2P systems. By embedding the process of searching data points of HSFC into the nodes of structured P2P networks and using the data search mechanism of networks, MLSQ can facilitate to search the data objects in accordance with query requirements.

该方法利用Hilbert空间填充曲线和潜在语义索引，将高维语义空间中相似的数据对象映射到一维数值空间中的邻近区域中，并以每个数据对象在一维数值空间中的序号作为键，将数据对象的索引分布到有组织P2P网络邻近的结点上，通过将HSFC中数据点的查找过程嵌入到有组织P2P网络的结点上，再利用网络的数据查找机制，MLSQ可方便地搜索到符合查询要求的数据对象。

The concern outspreads by two dimensions: the first starts off from individual existence and explores the rationality of it; the second is based on the provincen point, rethinking and questioning collective utopia. The specific representations are: the reflection on political utopia in historical memory through the material plight of the weak, the oppugnation of economic utopia by the delineation of the tragic fates under cultural puzzledom; the paradox of strength and absurdity caused by the loss of normality and rationality through the creation of the strong characters, which is also the contradiction between the modern call of "strength" and the criticism on the loss of morality; the meaning of existence for the intellectuals, the embarrassment they encounter in reality and the disillusion of collective utopia by the description of different life styles for the intellectuals.

这种关注在文本中表现为对三类人物的刻写：通过弱者在物质困境中的生存对历史记忆中政治乌托邦做出反思，从文化困境中弱者的命运悲剧对经济乌托邦做出质疑；通过强者形象写出了道德失范与理性缺失导致的强大与谬误同在的悖论；通过知识分子不同的生存方式，揭示了其存在的意义和在现实中的尴尬，以及知识分子试图重建群体乌托邦梦想的破灭。

Moreover,through the review of relevant literature on CIT,we find that there are still some aspects left uncovered or seldom covered. These aspects are as follows:(1)for the issue of the role of metonymy in conceptual integration,and the aspects of the role of metonymy in satisfying optimality principle;(2)the applications of metonymy in English and Chinese idiomatic expressions,especially in the two special kinds of Chinese idioms—set phrases and wisecracks.

通过对相关文献的回顾，我们发现还有一些方面论述较少或没有论述到，这些方面如下：(1)关于转喻在概念整合中的作用，以及转喻在满足概念整合的优化原则中的作用；(2)转喻在英语和汉语熟语中的应用，尤其是汉语熟语中所特有的两种形式，即成语和歇后语等转喻性和隐喻性表达在概念整合网络中的在线意义构建和幕后认知。

51 Orchidaceous species discovered by way of investigation fall into 32 genuses with 41 sedentary plants, 7 adnascent plants and 3 saprophyte plants. Sedentary plants distribute in the communities are composed of panacea, fagaceae, rosaceae, ericaceae plants with life form geophytes.

在调查中出现的32属51种兰科植物中有41种地生兰、7种附生兰和3种腐生兰，地生兰中以兰属植物中的春兰、蕙兰分布最广，生长在松科、山毛榉科、蔷薇科、杜鹃科等构成的植物群落中，生活型为真地下芽植物。

The Laser microprobe analysis shows that the argon isotope is evenly distributed in the muscovite. The preliminary conclusion is (1) muscovite in high-pressure metamorphic orthogneiss does not contain excess argon and can be the object for 40Ar/39Ar dating;(2) muscovite in the Qinglongshan eclogite contains large amounts of excess ...

由此得出的初步结论是：①高压变质的正片麻岩中的白云母中不含过剩Ar，这类矿物可以作为~(40)Ar/~(39)Ar同位素测年的对象；②青龙山榴辉岩中的白云母含大量过剩氩，而作为其围岩的超高压正片麻岩中的白云母却不含过剩氩，这一事实证明了榴辉岩中白云母的过剩氩不是来自围岩，而是榴辉岩自身继承的。

The influence of battery formula and technology parameter on the safety performance of mercury-free alkaline Zn/MnO2 button cell was explored.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
