在传播中

Based on the BISQ model, we studied the elastic wave speed in two-phase porous isotropic media and its relation with Biot-flow and squirt-flow. The Green function is obtained for a point load in the two-phase porous isotropic media using the decomposition of the field potencial and the properties of Delta function. The expression and effects of squirt-flow in BISQ-Green function are discussed.

AbstractThe Dissertation chiefly probes into trappings popular Arcanum, aimed at what result in fashion and fashion via what species mode spread raise the question, then with time for clue assays costume history various phase trappings variational rule, and wherewith for sally port reveals out result in trappings culture lengthways popular factor; at the same time the dissertation adduces today society trappings culture popular variety vehicle of transmission, via assaying different kinds of vehiculary advantage and disadvantage , elicits trappings cultural transverse direction spread mode .

论文主要探讨服饰流行的奥秘，针对什么导致流行和流行通过何种模式传播提出问题，接下来以时间为线索分析服装史各个阶段服饰变化的规律，并以此为突破口揭示出导致服饰文化纵向流行的因素；同时举出当今社会服饰文化流行的种种传播媒介，在分析各种媒介的优势与劣势的过程中，推导出服饰文化的横向传播模式。

When American Pop art met the Chinese modernism in that very context, a certain mystery was produced: Pop art was readily understood as a Dadaist destructive art, while its cultural deconstructive property seemed to be ignored. By the early 1990s, due to the political reason, China had undergone its rapid social and cultural transition from Enlightenment era to consumerist era, while artists, who were still in despair because of the failure of cultural Enlightenment movement, found themselves confronted with a completely new economic market and their ideas mingled with those of modernist Enlightenment and post-modern deconstruction.

它以风格上挪用、平面化、去意义、去价值这类语言策略解构和消除现代主义的启蒙神话，成为与后现代主义哲学同构的文化思潮。80年代初沃霍尔访华，尤其是1985年劳申伯在北京和拉萨举办个展开始了美国波普主义在中国的传播，而这时正值中国85现代主义运动的高潮，启蒙和反叛是这一运动的主题，正是这种语境使这种传播产生了十分吊诡的意义落差：波普主义很轻易地被理解为一种达达式的破坏性艺术，而它的文化解构主义色彩反倒不易被体会。90年代初中国社会由于政治的原因急促地完成了由启蒙文化向消费文化的转型，艺术家们还沉迷在文化启蒙运动失败的悲壮气氛中却突然发现自己已深陷在一个一完全陌生的经济世界中，理想的失落和批判身份的丧失使他们的思想开始混杂于现代主义的启蒙建设和后现代主义的解构观念之间，于是，波普主义成为这个时代的一种自然的风格选择。

Through the Laplace and Z transformations, it represents the varying features of electromechanical disturbance in a uniform chain network using the family of Bessel functions; the growing or attenuating laws are the same as that of electromechanical wave in a continuum model along the corresponding transmission media. Furthermore, the time of electromechanical disturbance arriving at any bus in the discrete model is also the same as that of electromechanical wave arriving at the corresponding bus in the continuum model.

通过Laplace和Z联合变换，用Bessel函数表示出机电扰动在均匀离散系统中的变化特征，得出扰动的增衰规律与连续体模型中机电波的增衰规律完全相同，而且离散系统中扰动传播到每一条母线所需要的时间与连续体模型中机电波传播到相应母线所需时间也完全相等。

Based on the results of previous research, we studied the relationship between the process of Tea Ceremony's spread in Japan and the Zen sect, the background of key experts those who have significant contributions in developing Tea Ceremony and come to the following conclusions: First, the Tea Ceremony stemmed from China; then it was brought to Japan by Bonzes and fully developed there.

在前人成果的基础上，通过对茶文化在日本的传播、普及过程中与禅宗之间的关系；日本茶道形成过程中各关键茶人名家的背景、其对茶道事业的贡献、作用；以及禅与日本茶道的关系这三个方面进行详细研究，得到以下结果：首先、饮茶文化源于中国，后由僧侣传至日本，并得以发展。虽然在日本茶道未正式形成之前，茶与禅宗并未发生本质性的关系，但是茶在日本的传播与普及却基本上有赖于僧侣们的宗教力量。
