查询词典 octahedron

In compound 1, Co is in a distorted octahedron environment with four nitro-gen atoms from the tripodal ligand and two oxygen atoms from the bridged oxalate, and the molecule is a dimmer-ic structure consisting of two LCo unites linked by bridging oxalate.

在配合物1中，Co与来自三脚架配体的4个氮和草酸根桥联配体的2个氧原子配位，处于扭曲八面体配位环境。由草酸根桥联两套LCo，构成了一个双核结构。

For comp ound 7, the cage is consisted by six MoO〓 and four PO〓. The six MoO〓 octahedrons have consisted to the loop structure, the there PO〓 tetra hedron become triangle and the other one lies the centre. The one oxygen of two MoO〓 octahedron is coordinated to Mn atom which linked the other cage like this cag e and this Mn have six ligands.

在化合物7中，每一个笼由6个MoO〓八面体和4个PO〓四面体构成，6个MoO〓八面体构成环，四个PO〓四面体形成一个三角形在其上面，4个P和6个Mo具有C〓的对称性，每二个MoO〓八面体提供一个O原子与Mn原子配位，这个Mn原子再与相同的这样的笼相连，形成一个中间细两端粗的形状，这个Mn原子是6配位的，每一个这样的笼再通过一个Mn原子连接起来，形成二维的网状结构，而这个Mn原子是五配位的。

The O2N3 of macrocycle and SO24 - coordinated with Cu2 +, Co2 + and Ni2 + to form a distorted octahedron .

Cu2，Co2Ni2+各自与环上O2N3和SO42-配合形成一个畸变八面体结构。

Ni6 cluster is an octahedron belonging to Oh point group. Its 3Eg orbital presents strong negative exchange coupling and has a trend of antiferromagnetic couplings. Ni5 cluster is of three-side pyramidal structure belonging to point group C3v. The magnetic moment direction of Ni atom lying on vertex of the pyramid is antiparallel to the moment direction of the Ni atoms lying on underside of the pyramid, which present the characteristic of ferrimagnetic couplings.

具有Oh点群对称的八面体原子簇Ni6的3Eg轨道上存在很强的负交换耦合，呈现反铁磁耦合趋势；具有C3v点群对称的三边金字塔结构的原子簇Ni5位于塔顶点的Ni原子与基面上的Ni原子磁矩方向相反，但大小不等，呈现出亚铁磁交换耦合特征。

Different from Ni70Mn25Co5（suitable for growing （100）crystal plate）, Fe is suitable for growing (111) crystal plate. It may be related to that (100)growing area of Fe is very narrow. In diamond research with medium of Fe, most crystals are octahedron or six-eight body. It is very hard to synthesize hexahedron diamond.

与Ni70Mn25Co5触媒生长特性（适合于（100）晶面生长）不同，Fe作触媒适合于（111）晶面生长，这可能跟Fe触媒的（100）生长区非常窄有关，因为在Fe触媒粉末金刚石研究中，晶体基本为八面体或六八面体，很难合成六面体金刚石。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
