高强度聚焦超声（HIFU）是一种新型的无创治疗肿瘤新技术,其中换能器声场数值计算能够为HIFU治疗提供重要的依据。传统非线性KZK和SBE模型广泛应用于换能器声场数值计算,但依然存在某些不足。我们采用一种介观尺度的新型流体力学方法,即格子Boltzmann方法（LBM）,基于2维9离散速度（D2Q9）格子构建了轴对称多弛豫参数LBM模型,并通过调节弛豫参数分析其对模型的影响;利用该模型对两个具有不同张角的球面聚焦换能器的声场进行数值模拟,并与KZK和SBE模型的计算结果进行比较。结果表明LBM模型能够很好地描述超声波的激发和传播机制,从流体力学的角度描述聚焦声场的分布,具有清晰的物理意义,且计算过程不受换能器张角的限制,在换能器声场的理论分析和模拟计算及其在HIFU治疗中的应用有着积极的意义。

要复原或者再现濒临危险的非物质文化我们还必须保护那些传承人,尤其是保护传承人的艺术精神,而这些艺术精神必须让表演者体验并生活在原初的环境中。但仅仅圈地或者通过音像和文字的记录以及专家学者的研究就能抢救和保护文化遗产吗?如何才能让非物质文化遗产获得长久的生命力?本文认为:非物质文化遗产保护工作的最终目的是要从非物质文化遗产中获得传统文化优秀的品质,获得可以让当代人领悟和鼓舞的人文精神,更重要的是在此项工作的开展中唤起全民对本民族优秀文化的自豪和认同感,唤起公众对我们伟大传统的热爱和尊重,认识到真正文化遗产的价值,摒弃文化糟粕。

原始思维作为一种古老的神话原型思维对探究任何文化的源头都有很重要的阐述功能。它能够解释一切起因不明的自然或社会文化现象,尤其在当前非物质文化遗产全面复兴并得到传承和保护的今天,传承非遗、利用非遗,进而发展非遗成为趋势,但怎样解释和分析非遗背后的故事、非遗深厚的文化涵义,需要从原始思维的研究中寻找答案。对非遗的深入阐释离不开原始思维的研究,非遗就是原始思维持续性或隐或显的多样态表达,并从巫术、隐喻、宗教三方面分析非遗和原始思维内在的关联。当代非遗的复兴正显示出人类对农耕文明成果的呼唤,是人类对共同文化遗产的需要,是对工业化时代人类生存的反抗和质疑。对非遗的当代阐释和利用,也有助于人类对非遗资源更深入的理解和利用。

为了解决认知无线电中,认知无线电用户(SU)如何在不干扰授权用户(PU)正常通信的情况下共享频谱资源和优化频谱使用的问题,该文在根据实际情况提出的markov的PU信道占用模型的基础上,针对PU的行为,制定了一套合理的SU多信道接入方案。分析了SU占用信道数以及感知周期对用户有效吞吐量的影响。通过最优化有效吞吐量问题的理论推导和分析,得出了解析解。通过与仿真结果的比较,验证了理论结果的正确性,分析了曲线变化的特点,得出有效吞吐量分别随SU占用信道数以及感知周期的增加而先增大后减小的结论。
