When the number of times of thermal fatigue cycle surpasses the critical valve Nc, cracks grow from initiating to continuous propagation. 当热疲劳循环周次超过临界值NC后,裂纹由萌生阶段发展到连续扩展阶段。
Afterwards, the church headquarters constantly sent missionaries into China in order to support the activities of their followers and to make the continuous propagation of Nestorianism. 之后,本部教会组织继续派遣传教士至华,支援中国境内景教徒的活动,使景教得以在华继续传播。
In the Yanshanian period, with continuous NW-directed propagation of the front of the southeastern Guangxi thrust nappe structure, the Jurassic-Cretaceous foreland basin also migrated continuously in a NW direction. 进入燕山期,随着桂东南逆冲推覆构造前缘不断地向NW方向扩展,侏罗纪&白垩纪时期的前陆盆地也不断地向NW方向迁移。
For the reason of the theory of human aural perception, in this paper, we present a system based on the fusion of multi-band Continuous HMM ( CHMM ) and Back Propagation Neural Network ( BPNN ). 根据人类的听觉感知机理,本文提出了一种改进的基于多带连续隐马尔科夫(CHMM)和BP神经网络融合的识别算法。
In this paper, the effects of continuous or sudden variation of cross-section and wave velocity on propagation and reflection of stress-wave in 1-D bar are discussed in consideration of the action of soil damping based on numerical analysis. 本文从数值分析角度探讨了在土阻尼作用下,应力波在一维变截面、变纵波速(突变或连续变化)杆中的传播及反射。
