The dimension and dispersion of the precipitation decrease, the lath character of bainitic ferrite tends to be evident.
碳化物尺寸变小，弥散度减小，贝氏体铁素体条片状特征明显；Unlike that of tempered martensite structure, there is little effect of oxygen content on the fatigue properties of ferrite-pearlite steel.
与调质回火马氏体组织不同，氧含量对铁素体-珠光体组织的疲劳性能没有明显的影响。The lamellar cementite in the pearlite broke up and a large number of granular cementite precipitate on the ferrite boundaries.
在相邻铁素体界隅及边界上出现大量颗粒状和膜片状的渗碳体。By analyzing the shape and arrangement of the fossil melanosomes, they were able to get clues to their original color.
通过分析化石黑素体的形状和分布，就可以得到它们原本颜色的线索。In conclusion, the fatigue properties of microstructure carefully controlled ferrite-pearlite steel could be as high as that of QT steel.
总之，组织精细控制的铁素体-珠光体型非调质钢的疲劳性能可达到调质钢的水平。Previous attempts to diagnose the colour of long extinct animals focused on pigment "containers" in feathers known as melanosomes.
Manning博士解释说，先前对复原早已灭绝的动物的体色的尝试，集中在研究黑素体上。A ferritic stainless steel alloy having a reduced tendency to form silica on at least a surface thereof also is provided.
也提供了在至少其表面具有减少的形成二氧化硅倾向的铁素体不锈钢合金。Ferrite bands with inside sulfides stretched along the rolling direction in the laminate area were the main cause of plate laminate.
指出了其沿轧向分布的铁素体带及其内部的条状或片状硫化物是中厚板分层的主要成因；The microstructure of weld bead obtained by shielded metal arc welding are massive ferrite and a little pearlite, HAZ are lath bainitic.
手工电弧焊焊缝组织主要为块状铁素体和少量珠光体，热影响区组织为板条状贝氏体组织；
