Comparative Study on the Omnidirectional Transmission Characteristics of Two Types One-dimensional Liquid-solid Phononic Crystals

研究了声纵波全向入射到两类一维流固声子晶体(第I类满足固体横波传播速度CST大于流体纵波传播速度Cl以及第II类CST<Cl)的透射特性。推导了其传递矩阵,并应用有限元方法进行验证,二者显示结果一致性.研究表明两类声子晶体呈现的不同声透射特征:第I类声子晶体中,高频声波在斜入射角大于第二全反射临界角条件下发生全反射现象,而低频声波却呈现全反射贯穿效应;第II类声子晶体中,在整个频段范围内均会出现周期性的透射导带。两类声子晶体均出现了低频声裂隙现象,第II类声子晶体低频声裂隙角范围明显大于第I类。The transmission characteristics of acoustic longitudinal wave propagating in two types onedimensional( 1D) liquid-solid periodic phononic crystals( type I satisfies: the shear velocity cstof solid material bigger than the longitudinal velocity clof liquid,while type II satisfies cst< cl) incited by omnidirectional incidence were investigated.A theoretical model of wave propagation in 1D solid-fluid periodic structure with omnidirectional incidence was established using the transfer matrix method,and the finite element method is used to test the correctness of our derivation,both methods show good consistence.For type I phononic crystal,total reflection phenomenon happens at high frequency,however,at low frequency total reflection tunneling effect appears.For type II,periodic band structures will take place in all frequency ranges.Acoustic band fracture appears in both types phononic crystal,however,the angle range of the fracture of type II is significant greater than type I's.国家自然科学基金(41276040;11174240); 福建省自然科学基金(2012J06010

Whole-brain functional magnetic resonance imaging of human brain during voluntary movements of dominant and subdominant hands

目的　利用全脑功能磁共振成像 (fMRI)技术 ,探讨参与利手和非利手简单随意运动的关键脑结构。方法　采用Siemens公司Sonata 1.5T磁共振成像系统 ,对 7名健康右利手志愿者的利手或非利手食指按键运动进行了全脑扫描。数据经头动矫正、空间标准化、空间平滑等预处理后 ,通过互相关分析分别获得利手和非利手运动的脑激活统计参数图。结果　利手运动主要激活对侧初级运动区 (MI)、双侧辅助运动区 (SMA)、双侧运动二区 (MII)和同侧小脑 ,而非利手运动除以上区域外还激活了对侧前运动区 (PMC) ,而且SMA和MII的激活体积大于利手运动。结论　全脑fMRI研究表明 ,随意运动依赖于大脑皮质和小脑等许多脑结构的参与。与利手运动相比 ,非利手运动更依赖于SMA和PMC等高级运动控制区
