以“可持续制造”为主题的大型装备制造领域，能源消耗大户的锻造业需要进行锻件性能评价的完善和锻造工艺的提升，这依赖于此锻件品质在服役环境中高性能、长寿命方面的表现。因此，本研究针对汽轮机钛合金长叶片展开锻造加工效应下的性能合理评价及寿命可靠预测模型的研究，主要包括:(1)通过揭示钛合金锻件工艺相关的微观结构和残余应力的形成与演变规律，实现锻造加工相关的完整性关键特征参量的提取;(2)澄清服役环境中锻造加工诱发的残余应力释放机制，建立环境—残余应力—微观组织综合效应的映射关系，合理描述三者对材料环境致裂抗力的

在纵向通风隧道内车厢内火灾溢出火羽流条件下，由于车厢自身对溢出火羽流卷吸的限制作用，再加上车厢阻塞效应形成的复杂流场，必将导致溢出火羽流的卷吸行为及其烟气层特征参数演化与分布发生明显改变，原有基于自由火羽流建立的隧道火灾经典模型不再适用。本项目拟通过理论分析、实验研究和数值模拟分析，揭示纵向通风隧道内车厢溢出火羽流的卷吸行为与烟气层特征参数演化规律:.(1)建立纵向通风隧道内车厢溢出火羽流火焰形态、溢出火羽流温度分布和顶棚最高温度分布理论表征模型;.(2)揭示纵向通风隧道内车厢溢出火羽流的烟气层卷吸特性与

PROJECT SUMMARY It has long been known that methylation of genomic DNA correlates with gene expression. However, the structural mechanisms that underlie these observations remain obscure. In this project, we will pursue several innovative strategies for s

DESCRIPTION (provided by applicant): Homologous recombination (HR) mediated repair of DNA double-strand breaks (DSB) utilizes a number of tumor suppressors like BRCA1, BRCA2, FA proteins, Nbs1, ATM, that are often mutated or repressed in cancers and cance
