With recent attention to high power energy and its interaction with materials of different type,both in industry and military application,this paper covers a short review course into subject of materials response in respect to such high power energy laser
今年上半年,我国玩具外贸企业大都陷入在“矛盾”之中。一方面是新冠肺炎疫情冲击全球其他玩具产地,使得订单回流中国,玩具企业迎来订单的爆发,玩具外贸出口总额实现同比增长;另一方面是货柜短缺、各种费用及成本上涨,使得部分企业面临增量不增利等窘境。
鸣谢:本次调查得到以上12家商场的大力支持,在此表示衷心感谢!
"先验的"(transcendental)和"超验的"(transzendent),以及相应的,"先验性"和"超验性",乃是胡塞尔先验现象学的核心概念,准确地理解和把握这一组密切关联的概念,对于理解胡塞尔现象学的工作、性质和目的,尤其他在认识论中所取得的成就,具有关键的意义.现象学在汉语学界已蔚为显学,不过,在准确地理解和把握胡塞尔现象学的根本宗旨、核心观念和基本性质方面,依然有待于从基础层面入手进行更为深入、细致和系统的研究和考察.同时,有关这一组术语的汉语对译的争论,在一定程度上透露出了汉语现象学研究
We investigate the asymptotic behavior of solutions to the initial boundary value problem for the micropolar fluid model in a half line R+:=(0,∞).Inspired by the relationship between a micropolar fluid model and Navier-Stokes equations,we prove that the c
We study the regularity of weak solutions to a class of second order parabolic system under only the assumption of continuous coefficients.We prove that the weak solution u to such system is locally Holder continuous with any exponent α∈(0,1)outside a sin
<strong>Introduction:</strong> The goal of this study was to utilize physical characteristics instead of placing subjects in arbitrary diagnostic categories to test for associations with genetic variants. <strong>Methods:</strong>
Two new nitronyl nitroxide Cu(II) complexes {[Cu(hfac)<sub>2</sub>]<sub>2</sub>(NIT-4PyPh)}<sub>2</sub>(<strong>1</strong>) and [Cu(hfac)<sub>2</sub>][(NIT-3PyPh)<sub>2</sub>](<str
电视弹幕广告作为弹幕技术在电视媒介中的拓展应用,实现了从小众走向大众的渐成规模式发展。弹幕广告的形态经历了由最初单纯的自发弹幕行为到实时互动的弹幕形态,进而再到与电视等传统媒介结合形成新形态的嬗变,提升了电视媒介广告的娱乐性、互动性和观众黏性。本文在简要阐述电视弹幕广告的基本内涵及特征上,结合弹幕广告的发展对电视弹幕广告的形态嬗变进行分析,最后对电视弹幕广告所蕴含的创意蕴意予以揭示。
《天龙八部》是中国武侠小说的重要代表作品,它与古希腊悲剧典范《俄狄浦斯王》看似风牛马不相及,但是分析其主要人物——萧峰和俄狄浦斯,可以发现,无论是萧峰还是俄狄浦斯身上,都有着相似的悲剧色彩。这种与生俱来的无法逃避的悲剧命运,将两个看似毫无关联的人紧密联系在一起。
