1·The pearlitic rail steel was widely used as rail track in China for its prominent performance in anti-wearing and high yield strength.
珠光体轨道钢是目前我国铁路轨道采用的主要钢种，其性能特点是抗磨损性能好，屈服强度高。
2·Pearlitic transformation in steel is a typical diffusion eutectoid transition.
钢中珠光体转变属典型的扩散型共析转变。
3·Relationship between microstructure of pearlitic rail steels and mechanical properties, and the effects of alloying elements are subject, which people have always been studying.
珠光体钢轨钢的组织与性能之间的关系、合金元素的作用机理一直是人们不断研究的课题。
4·At the last, the steps mechanism of pearlitic growing and some eutectoid structures of non Fe-C alloys are pointed out.
最后讲述了珠光体生长的台阶机制及一些非铁碳合金的共析组织。
5·The effects of magnetic field on heat conduction of ferritic and pearlitic steels in the magnetic field heat treatment were studied.
研究结果表明：在磁场热处理铁素体钢或珠光体钢时，磁场能够显著地促进钢的传导传热、加速钢材的冷却、细化铁素体晶粒。
