The substance is made out of tiny hollow metallic tubes arranged into a micro-lattice-a criss-crossing diagonal pattern with small open spaces between the tubes. 这种材料是由微小的空心金属管排列在微型格子里制作成的&在这种微型格子上,金属小管呈对角线型纵横交错地排列,管子之间有微小的开放的空间。
A metallic bellows is made from a thin seamless tube. When pattern pieces are laid out on plaids or stripes they must be matched at the seam line and corresponding crossmarks. 金属波纹管是由薄壁无缝管制成的。在格子布或条纹布上排料时,缝线必须对格对条。

Diagnosing corrosion modality system of metallic material in seawater based on fuzzy pattern recognition 基于模糊模式识别的金属材料海水腐蚀形貌诊断系统
So how to convert the rapid prototypes into metal functional exemplars ( especially, this kind of important technical equipments like metallic pattern& tooling) will greatly influence the application of the high-new technology. 如何将这些快速原型转化成金属功能样件(特别是金属工模具这种重要的工艺装备)就成为影响这种高新技术应用的关键。
Finally, the structure of single SRRA was improved by a quasi-Ω-like metallic pattern and a compound material with negative index of refraction was obtained. 对单金属环阵列结构进行了改进,得到了一种体现负折射率效应的准Ω结构的复合介质。
The geochemical features of fluid inclusions are basically identical, for these fluids are belong in H2O-CO2 system, contain the same metallic elements of Au, Cu, Co, Cd etc and possess specifically isotopic constitution of hydrogen and oxygen in rare-earth pattern of positive europium abnormality. 石英包裹体中流体的地球化学特征基本相似,属H2O&CO2体系,含Au、Cu、Co、Cd等金属元素,具独特的氢氧同位素组成和正铕异常的稀土模式。
Taking the grey distribution of metallic samples and their corrosion modality as the knowledge base, the diagnosing system identifying corrosion modality of metallic material in seawater was established according to the theory of fuzzy pattern recognition. The images can be identified by grey distribution. 将所得样本的灰度值分布和对应的腐蚀形貌作为知识库的标准样本,用模糊模式识别理论建立了腐蚀形貌诊断系统,可以由扫描灰度值分布判断金属的表面腐蚀形貌。
TG/ DSC curves confirmed that the most of iron oxides produced by Fe N 2O reaction could be reduced to metallic iron in the presence of CO. XRD pattern revealed that the N 2O reacted with iron to yield Fe 2O 3 as the major product. TG/DSC曲线表明了在Fe与N2O反应过程中CO的作用表现为通过与N2O在反应表面的竞争吸附使铁氧化物还原为金属铁,X射线衍射证明Fe与N2O反应后的氧化物为Fe2O3;
