Basing on past investigations into experiments for concrete, an empirical rate-dependent cap model is proposed and adopted to simulate the behavior of concrete response to planar impact at lower velocities.
从连续损伤理论出发 ,讨论了盖帽模型。
InAs quantum dots(QDs) with different cap layers were fabricated by molecule beam epitaxy(MBE) system.
采用变温及时间分辨光致发光谱研究了MBE设备生长的具有不同盖帽层的InAs量子点样品。
