查询词典 dendritic structure

It was founded that the hardness distribution is approximately symmetrical to the center of welding line , the weakest zone of the whole joint is about 10mm from the center of the welding line . The HAZ of the welding line has an intenerate zone. the center of the welding line presents a typical dendritic casting structure.

结果表明：焊接接头的硬度以焊缝中心线为对称轴呈近似对称分布，焊接接头的最薄弱环节位于距焊缝中心约10mm处，焊接接头的热影响区内存在一个软化区。

The results show that formation of FeO*Cr2O3 induces wetting in reaction between the liquid ceramics and outer stainless steel pipe. The ceramics structure can be divided into three zones, i.e. pin microlite, columnar and dendritic zone.

试验结果表明：外层钢管与内衬陶瓷间因形成FeO*Cr2O3尖晶石相而产生反应润湿，陶瓷层由隐针状内层、柱状中间层和外层树枝晶组成。

Expect for a few pittings,the N+1-implanted surface had a best fineness (average roughness Ra≈4.2nm), close to the unimplanted original surface.The N+2-implanted surface had a black dendritic area,and had a poorer fineness (Ra≈16nm).While in the N+10-implanted surface appeared a ripple structure,with the poorest fineness (Ra≈40nm).

但其表面形貌各异：N+1注入的表面除存在少量点蚀坑外，光洁度最高(平均粗糙度Ra≈4.2nm)，接近未注入前的原始表面(Ra≈3.5nm)；N+2注入的出现黑色枝状区域，光洁度次之(Ra≈16nm)，而N+10注入的则出现&波纹&状结构，光洁度最差(Ra≈40nm)。
