八价的

At diakinesis, 0.2 tetravalents, 0.05 hexavalents and 0.05 octovalents per pollen mother cell were detected, which was absent in cultivated cucumber. In 30% PMCs, crossed chromosomes occurred at diakinesis.

在减数分裂终变期，平均每个花粉母细胞有0.2个四价体、0.05个六价体和0.05个八价体，约30%的花粉母细胞中存在拉十字的染色体。

It was reported that Indium complex had anti-cancer activity.The electronic structure of Indium is4d~25s~1 and its ions forms are of In and In.In can form easily octahedral complex with chelating atoms.

有报道称铟的配合物能与DNA作用且有抗癌活性，铟最外层具有4d~25s~1结构，其离子常见价态为In，In，并易形成六配位的八面体结构配合物。

Werner was correct, however, in his conclusions concerning the octahedral geometry of coordination number 6 for cobalt and platinum.

然而，对于钴和四价的铂等配位数为6的八面体几何构形的结论，沃纳是对的。

The blue and purplish blue color derives from octahedral cordination formed with di -valence cobalt and ferric ion.

蓝色的至色机理是二价的钴离子和二价的铁离子构成的配位八面体对光的选择性吸收。

The overvalue phenomenon was clearly demonstrated in 1980s' US real estate loan default.

这一超价现象明显的表现在美国八十年代房地产的信贷危机上。

Article 28. A seller has the right to set a reserve price.

第二十八条委托人有权确定拍卖标的的保留价并要求拍卖人保密。

第二十八条委托人有权确定拍卖标的的保留价并要求拍卖人保密。

There exists isomorphous replacement in the rutile structure, and the most prominent feature is the average content of oxides, being 1.22%, 0.39%, 0.35% and 0.22% for V 2O 5, Fe 2O 3, ZnO and CuO respectively. They substitute Ti 4+ in octahedra. The valence of V is 5, and its polyhedron is trigonal bipyramid, which causes the lattice distortion, breaks the raw octahedron symmetry into square bipyramid, and produces the microstrains in the structure.

天然含钒金红石平均含V2O5可达1.22％，Fe2O30.39％，ZnO0.35％，CuO0.22％，这些金属离子可替代八面体中Ti^4 。V以5价形式存在，配位多面体呈三方双锥，其在晶格内部对Ti的替代导致晶格畸变，打破了配位多面体原有的八面体对称而呈四方双锥的几何形态，并产生结构微应力。

Some further approximations lead to a simple formula that expresses the barrier for nonidentity and identity hydrogen abstraction reactions as a function of the bond strengths of reactants and products.

第八章利用从头算价键计算方法结合价态相关图模型研究了卤族非等同氢提取反应，并对此类非等同氢提取反应做了归纳，推导出描述此类化学反应的能垒的普适半经验公式。

Mn(H_3biim)_2_2Cl_2 and Cd(H_3biim)_2_2Cl_2 have been synthesized from H_2biim, their structures were determined by X-ray crystallography. The two complexes have similar structures and both are neutral compounds. One N atom in H_2biim is protonated, forming a H3biim+ cation. The later is an unidentate ligand, the central metal, Cd or Mn is six coordinated and adopts a distorted octahedral environment.

合成了联咪唑锰配合物Mn(H_3biim)_2_2Cl_2和联咪唑镉配合物Cd(H_3biim)_2_2Cl_2，晶体结构表明这两个配合物结构相似，均为中性化合物，联咪唑的一个氮原子被质子化，形成一价阳离子(H_3biim~+)，它采取单齿配位，中心Mn原子是六配位，其配位环境为畸变的八面体。

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。
