在这些经济带或城市密集区中，随着生产要素的进一步集聚和扩散，最终形成了一个个具有当地特色的产业集群。
With factors of production gathering and spreading further, the industrial clusters have formed finally with characteristic locality in these economy belts and city-intensive areas.
结果表明：只有微分干涉相衬法光学金相才清晰地显示了熔合区扩散过渡层存在白亮、光滑、无胞状柱状凝固特征的“白亮带”和具有胞状凝固特征的后续熔化滞留层。
The results show that "the bright band" and "follow-up melted stagnant layer" are clearly observed only with differential interference contrast and has bright and no cellar-columnar.
对于扩散火焰，高温区在OH带内侧；而对于预混火焰，二者基本一致。
The high temperature zone is at inner side of OH zone for the diffusion flame, but both zones are approximately at the same position for the premixed flame.
经分析得知母带与凝固层的界面结合是靠元素相互扩散形成过渡区实现的。
The analysis results show that the mother band and solidified layer are bonded through the transition lay…
