Many research works have shown that the microstructural control of TiAl alloys have an important influence on their mechanical properties, and also found that the grain size, the interlamellar spacing and the α〓/γ volume fraction of the microstructural features are the key factors of microstructural control.

已有的研究确定了TiAl合金的显微组织控制对其力学性能有着重大的影响，提出了TiAl合金的显微组织中晶粒大小，片层间距和α〓/γ相比例等是组织控制的主要因素。

The results show that with the finishing temperature at 950 ℃, as the cooling rate increases, interlamellar spacings of pearlite is reduced; as cooling rate reaches 5℃/s, martensite precipitates.

结果表明，随着冷却速度的加快，高碳钢SWRH77B在950℃变形时，其珠光体的片层间距变细；冷却速度达到5℃/s时，有马氏体组织析出。

Through the comparison of this model with Miller and Smith's shear cracking model, it can be shown that the smaller the interlamellar spacing of pearlite is, the higher the resistance of crack initiation and propagation will be.

该模型与Miller和Smith提出的剪切开裂模型的比较可以说明，珠光体片层间距越细小，裂纹萌生和扩展的阻力越大。

The stability of lamellae decreases with decreasing interlamellar spacing and discontinuous coarsening occurres during aging.

层状组织的稳定性随片间距减小而降低，表现为时效时发生不连续粗化。

The test results show that the contact fatigued microstructure characters mainly the reduction of pearlitic interlamellar spacing, the formation of different type of substructures as well as the deformation and fracture of cementitic lamellar in pearlite.

结果表明，PD3钢轨钢接触疲劳变形组织的主要特征是：珠光体片层间距的减小；不同类型亚结构的形成；渗碳体的变形与断裂。

The finer the pearlitic interlamellar, the more the plastical deformation and the higher the ability of deformation strengthening.

珠光体原始片层间距越细小，塑性变形特征越显著，形变强化能力越高。

With the addition of Al of about 1 wt%, the proeutectoid cementites were restrained during equilibrium transformation and dynamic phase transformation, the stability of undercooled austenite during deformation was increased, retarding the formation of pearlite and the interlamellar spacing of pearlite was decreased.

Al的加入使动态相变过程中奥氏体的稳定性提高、珠光体转变推迟，进一步细化了珠光体片层间距。

Exposed rock strata range from the 1.7 billion-year-old Vishnu Schist of the Inner Gorge, to the pale caprock Kaibab limestone deposited 250 million years ago, to the 1 million-year-old black lava flows in the western canyon.

In 54 cases (56 eyes) lamellar corneal grafting was performed with these buttons.

用这种角膜片共做了54例(56只眼)板层角膜移植术。

Ninteen cases were lamellarly scaned C2 section on axis by MRI without interval.

将MRI和X线平片两种影像学检查诊断颈椎损伤的337病例进行对比分析，其中19例病例MRI C2区局部轴位薄层无间隔扫描。
