The content of pearlite in alloy exceeded 95% and the content of cementite was under 5%.

该铸铁的珠光体含量大于95%，渗碳体小于5%，抗拉强度可达700~850MPa，硬度为280~350HB，延伸率为3%~5%。

A little of RE can refine the grain size of the austenite, decrease the laminae pearlite cementite.

少量的固溶稀土可以细化BNbRE重轨钢的奥氏体晶粒和珠光体片层结构。

The cementite in the pearlite by ECAP has a stronger ability of spheroidization at a lower annealing temperature.

经ECAP变形的珠光体组织在较低温度退火时，渗碳体具有较强的球化能力。

For example, the TTT diagram for a 0.8% C steel is a continuous curve although there is both a pearlite and bainite reaction occurring, but it is difficult to disentangle the reactions sufficiently to study their kinetics.

例如，TTT图中，0.8 ％的碳钢是一个连续的曲线虽然是珠光体和贝氏体反应都发生，但是难以将这两个反应分开而充分研究其各自的动力学。

The chemical composition and the production process of the high strength hot rolled sheet steel for electrostatic enameling are introduced briefly.

简述了工业生产高强度热轧薄钢板的成分和生产工艺，其室温组织由极细的铁素体晶粒和极少量的珠光体组成。

The chemical composition and the production process of the high strength hot rolled sheet steel for electrostatic enameling are introduced briefly. The microstructure of the steel is composed of fine grained ferrite and tiny amount of pearlite.

简述了工业生产高强度热轧薄钢板的成分和生产工艺，其室温组织由极细的铁素体晶粒和极少量的珠光体组成。

The resulting structure is a mixture of primary or pro-eutectoid ferrite (ferrite that formed above the eutectoid reaction) and regions of pearlite.

作为结果的组织结构是初步的共析铁素体和部分珠光体的混合物。

The results indicate that the fraction of pearlite in the ductile iron matrix increase with increase of copper and the decrease of silicon in this investigation.

研究表明，在试验范围内，随着铜含量增加和硅含量减少，球铁基体中的珠光体数量增多。

As before, any remaining austenite transforms to pearlite upon slow cooling through this temperature.

就像以前说的一样，当缓慢冷却到这温度时所有剩余奥氏体转化为珠光体。

The results showed that the best controlled cooling technology was the third test scheme, that is, some blowers with 100% opened angle, and the microstructure of the wire rod with best comprehensive mechanical properties was sorbite and a little of pearlite.

结果表明，最佳工艺是部分风机开口度为100%，盘条金相组织为索氏体+少量珠光体，综合力学性能最好。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
