Many of the particles in the atmosphere are in the intermediate region of size . 大气中的许多粒子均属中等尺度。
Test results and analysis show that the above equation can be applied to represent the fcp test results of various materials in the near - threshold region , the intermediate region of stable crack propagation and the rapid crack propagation region measured at different stress ratios 实验结果和分析证明,该式能用于描述具有各种不同特性材料的包含近门槛区、中部稳态扩展区和快速扩展区的整个疲劳裂纹扩展曲线。
Main conclusions or / and creative work are given in following . all materials have same fcp pattern , i . e . , the whole fcp curve comprises the near - threshold region , the intermediate region of stable crack propagation and the rapid crack propagation region and with s shape , though the materials have different micro - mechanisms of fcp 本文的主要结论和创新点有:首先,认为所有固体材料均具有相同的疲劳裂纹扩展宏观规律,即完整的疲劳裂纹扩展曲线都由近门槛区、中部稳定扩展区和快速扩展区所构成,曲线具有相似的s形,尽管不同特性的材料具有不同的疲劳裂纹扩展的微观机制。
The sequence is : non - classical ng supersaturated solid solution spinodal decomposition the variation in precipitation mechanism of 8 " phase in intermediate region is systematically investigated firstly , and it is found that with the increase of composition the precipitation characteristic transforms from that of metastable to instable region gradually 首次发现l12有序畴之间首先形成较宽的重合位置点阵,随时间延续,重合位置点阵逐渐向ll :结构转变,在两有序畴之间形成反相畴界,随后,由于合金发生分解,反相畴界被有序一无序界面替代。
Based on the analysis and summation , a new formula for fcp is developed as eq . ( 3 . 23 ) or eq . ( 6 . 5 ) , and can be applied to describe the fcp pattern in all three fcp regions , including the fcp in the near - threshold region , the intermediate region of stable crack propagation and the rapid crack propagation region 在上述总结和分析的基础上,给出了描述三个区的疲劳裂纹扩展总体规律的公式( 3 . 23 )或式( 6 . 5 ) ,即上述表达式左、右两端量纲一致,式中的各个参量物理意义明确。
