八倍体

The analysis result indicates that the chromosome number of 38 accessions is ranged from 63 to 90 as same as septuploid, octoploid, enneaploid and decaploid, respective.

结果发现台湾鱼腥草收集品染色体数目介於63~90条之间，分别为七、八、九及十倍体，另发现染色体数84与85条之异数体收集品。

""I have known Captain Savery, at York's buildings, to make steam eight or ten times stronger than common air; and then its heat was so great that it would melt common soft solder, and its strength so great as to blow open several joints of the machine; so that he was forced to be at the pains and charge to have all his joints soldered with hard solder.

""我知道（萨弗里队长，在纽约的建筑物，使蒸汽八名或10倍强，比常见的空气；然后，其热量是如此巨大，它将熔体常见的软钎料，其强度很大，吹开几个节点的机器；使他被迫要在痛苦和主管有他的所有接头焊接硬钎料。

A new picorna-like virus was isolated from dead Evtropis oblique larvae deceased from NPV infection. Electron microscopic observations of purified virions were non-enveloped isometric particles with diameter of 26nm. The virions contain two capsid proteins: 31.5kDa and 28.8kDa, the amount of later is 2.5 times more than that of the former. Analysis of 3′terminal sequence of EoPV clone identified that it can encode RdRp and has eight conserved motifs. Homology analysis shows that it is closely related to Perina nuda picorna-like virus.

从核型多角体病毒感染致死的茶尺蠖幼虫尸体中分离到一株微小RNA病毒透射电镜观察纯化的病毒粒子为无囊膜、无表面特征、直径约26nm的球状颗粒。16%的SDS-PAGE显示它有两个分子量为31.5 kDa和28.8 kDa的衣壳蛋白，后者的含量是前者的2.5倍。3′端克隆序列分析表明EoPV基因组3′有poly尾，编码RNA聚合酶，含有微小RNA病毒RNA聚合酶的八个保守基序，同源性分析表明它与榕透翅毒蛾微小RNA病毒亲缘关系最近。

Cage hexahedral silsesquioxane (T 8), an octamer, each of its sides consists of silicon and oxygen ring. From which, many kinds of macromer and related inorganic/organic nanocomposites containing inorganic silicon dioxide core have been prepared.

笼型六面体倍半硅氧烷(T8)是一类每个面都由硅氧八元环构成的六面体，从它出发可制得以二氧化硅为核心的大分子单体以及无机/有机纳米复合材料。

Then the surface of the star polymer was intramolecularly crosslinked using octa(3-azidopropyl)polyhedral oligomeric silsesquioxane, POSS-(N_3)_8,as the inorganic multifunctional crosslinker at high dilution concentration via click chemistry,forming a novel POSS/polymer hybrid nanostructure.Thermogravimetric analysis shows that after surface crosslinking, the thermostability of the core crosslinked PS can be remarkably improved.In the second work,we synthesized of a novel polymer with quatrefoil-shaped topology.

接着，我们合成了一种结构规整的含八个叠氮功能团的无机分子—多面低聚倍半硅氧烷，以其为交联剂，我们通过Click反应在即稀浓度下实现了前驱体星型聚合物的分子内表面交联，得到了外层为无机分子交联，内层为有机高分子的星状高分子，这种新型的星状聚合物表现出了优良的热稳定性能。

Employing high-dilute method and 5-fold excess amine prepared two new "two-armed" acyclic diamine intermediates I_a and I_b, which are also intermediates of synthesizing microcyclic compounds, and eight aromatic Schiff bases, II_, were synthesized from reaction of I_a or I_b condensing with different aromatic aldehydes. Their composition and structure were characterized by Elemental analysis, IR, UV-Vis, LIF,~1HNMR and MS. The hydrogen bond interactions and MS fragmental patterns were also discussed.3. Several novel transition metal complexes using II_a as ligand were synthesized and identified by Elemental analysis, IR, UV-Vis,~1HNMR and molar conductivity.

1，采用高度稀释及胺过量五倍的方法合成了两个具有吡啶双酰胺臂的非环二胺Ⅰ_a和Ⅰ_b，并以它们为中间体进一步合成了八个芳香席夫碱Ⅱ_a-Ⅱ_h，通过元素分析及各种波谱测试鉴定了它们的组成与结构，对化合物的UV-Vis、LIF、IR、~1HNMR及MS进行了较为详细的讨论，还探讨了席夫碱的氢键相互作用及质谱裂解方式； 2，以席夫碱Ⅱ_a为配体合成了几个新型的过渡金属配合物，并通过元素分析、UV-Vis、IR、~1HNMR、摩尔电导及DTA—TG对其进行了表征，讨论了化合物的配位情况及配体在配位中的脱质子行为。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
