Ultrasound imaging is the most widely used noninvasive medical imaging modality. Its latest elite concept is Superharmonic Imaging which is the most talked-about future of medical diagnostic ultrasound.In this paper,the computational and analytical study for superharmonic field generation from phased array transducer of 16×16 elements is presented. For this,the model preferred,includes the calculation for diffraction effect in frequency domain and nonlinear effect in time domain.The attenuation is included along with the diffraction in frequency domain as well.The comparative analysis of superharmonic field is also carried out with simulated fundamental and second harmonic fields by the same model.Similarly,the comparison with the results from the literature is also reported.

课程知识的社会性分析    课程系统内部诸要素包括课程目标、课程类型、课程知识或课程内容、课程实施、课程评价等,其中最核心的是课程知识特别是课程知识的分配问题,它们都打上了社会学的性质与痕迹。选择什么知识作为课程的内容很大程度上受制于社会的政治经济的制约。就课程类型来看,事实上,潜课程的社会功能就在于社会控制;就课程知识来看,社会如何选择、分配、分类、传递、评价其公共的教育知识,既反映了社会权利的

摘要:一般认为,现行的物权法所规定的物权保护方法均属于物权请求权类型。但从历史渊源的角度出发,传统的物权请求权类型中并不包括恢复原状和损害赔偿请求权;从逻辑结构上看,恢复原状和损害赔偿请求权行使时,原权利基础和其他三项并不类似;从行使要件上看,恢复原状和损害赔偿请求权和其他的也不同。所以,笔者认为物权法所规定的五种类型的保护方法中,恢复原状和损害赔偿请求权并不属于物权请求权的范围。  关键词:物权
