为了揭示珊瑚砂对应力波的衰减效应,基于改进的split Hopkinson pressure bar(SHPB)装置,对干燥珊瑚砂长试件中的应力波衰减规律进行实验研究。定量测量到应力波在珊瑚砂中的平均传播速度,提出无量纲的峰值应力随传播距离的衰减公式。分析结果表明,试件端部冲击引起的应力波在75和225 mm的传播距离上可使峰值应力分别衰减至10%和1%;峰值应力速度随着传播距离的增大而减小,随无量纲峰值应力的减小而减小;与已有规范中基于陆源砂土...

Pressure overload(PO) first causes cardiac hypertrophy and then heart failure(HF), which are associated with sex differences in cardiac morphology and function. We aimed to identify genes that may cause HF-related sex differences. We used a transverse aortic constriction(TAC) mouse model leading to hypertrophy without sex differences in cardiac function after 2 weeks, but with sex differences in...

1 Introduction Recent improvements in the precision of Li and B isotope measurements have demonstrated the potential of these elements in tracing a wide range of geological processes. The Li and B isotope systematics of ultrahigh-pressure (UHP) metamorphic rocks provides a unique opportunity to investigate the behaviour of Li and B during fluid-rock interaction at high temperatures and v...
