The official dress systems of Ming and Qing Dynasties were formulated by the rulers of those feudal societies to maintain their ruling *** well as being a functional indication of the type and power of officials,the rank badge,Buzi or Bufu(补子,补服),on official clothes indirectly declared the elegant and brave characteristics of civil and military officers,and also reflected the philosophy of the unity and harmony between human and *** by social semiotics theory,the Buzi patterns embody the culture and arts of ancient Chinese clothing,producing novel meaning within corresponding social contexts,which can be inherited and developed in today's ***,the wearing of official unified clothes and rank badges by officials and civil servants should be encouraged since those persons often serve as a role model and are subject to public's *** ancient Chinese culture and arts can flourish,a good social order and law be maintained,and a harmonious and civilized society built.

Two-dimensional time-resolved particle image velocimetry(TR-PIV)and stereographic particle image velocimetry(SPIV)techniques were used to investigate the effect of leading-edge tubercles on the flow over low-aspect-ratio wing *** angle of attack is fixed at 10°,and the Reynolds number based on chord length is 5.8×10^(3).It is shown that the leading-edge tubercles can effectively mitigate flow separation in the model and also reduce the contribution of wake vortex to the fluctuating energy of ***-rotating vortex pairs(CVPs)initiated from the peak of leading-edge tubercles can promote nearby momentum exchange,enhance mixing of the flow and increase the energy contained in the boundary layer,which results in resisting the larger adverse pressure ***,it is concluded that CVPs play an important role in mitigating the flow separation for wings with leading-edge tubercles.

The elevational distributions of bacterial communities in natural mountain forests,especially along large elevational gradients,have been studied for many ***,the distributional patterns that underlie variations in soil bacterial communities along small-scale elevational gradients in urban ecosystems are not yet well *** Illumina MiSeq DNA sequencing,we surveyed soil bacterial communities at three elevations on Zijin Mountain in Nanjing City:the hilltop(300 m a.s.l.),the hillside(150 m a.s.l.),and the foot of the hill(0 m a.s.l.).The results showed that edaphic properties differed significantly with *** community composition,rather than alpha diversity,strongly differed among the three elevations(Adonis:R2=0.12,P<0.01).Adonis and DistLM analyses demonstrated that bacterial community composition was highly correlated with soil pH,elevation,total nitrogen(TN),and dissolved organic carbon(DOC).The degree scores,betweenness centralities,and composition of keystone species were distinct among the *** results demonstrate strong elevational partitioning in the distributions of soil bacterial communities along the gradient on Zijin *** pH and elevation together drove the smallscale elevational distribution of soil bacterial *** study broadens our understanding of distribution patterns and biotic co-occurrence associations of soil bacterial communities from large elevational gradients to short elevational gradients.

In this paper,the phenomena of Mg_(2)Sn-induced Sn whisker growth were explored on the surfaces of Mg/Sn/Mg ultrasonic-assisted soldering joints after aging *** in-situ observation and thermal analysis confirmed that the formation and the corrosion of Mg_(2)Sn nanoparticles were the dominant reason of Sn whisker *** Mg_(2)Sn accumulation at the grain boundaries would pin the dislocation slip and affect the continuity of whisker growth,and the boundary angle would thus play a decisive role in the growth shape of Sn whiskers due to the pining effect of Mg_(2)*** study might be conducive to elucidating the growth behavior of Sn whiskers and provide the exploration strategy to further improve the bonding strength of Mg/Sn/Mg ultrasonic-assisted soldering joints.

中国正面临工业遗产保护和城市可持续更新的双重挑战。分析美国工业遗产再利用与城市复兴相结合的成功案例——马萨诸塞州当代艺术博物馆MASS MoCA。MASS MoCA是通过当代艺术,推动位置偏远的中小型后工业城市成功转型为区域文化创意产业集群发展中心的经典案例。认为MASS MoCA成功的方法在于共享遗产理念下城市遗产与城市更新的相互促进,即基于价值共享、空间共享、利益共享下的可持续更新路径。MASS MoCA的案例研究将为我国以文化创意为导向的工业遗产再利用和中小型工业城市转型提供借鉴。

利用硝化型生物絮团系统进行凡纳滨对虾的养殖,并通过设置不同的养殖密度探究不同养殖密度下硝化型生物絮团系统对凡纳滨对虾生长性能和水质情况的影响。实验选择同一批标粗到一定规格的健康凡纳滨对虾[体长(4.80±0.25) cm,体质量(0.98±0.16)g],分成5个密度梯度组放养到养殖池中,进行为期45 d的养殖。结果表明:80~610尾/m^3范围内,硝化型生物絮团系统对非离子氨和亚硝酸盐氮可以控制在警戒浓度(0.2 mg/L)附近波动,为凡纳滨对虾健康生长提供了良好的环境,保证养殖存活率,另外该系统下适当的排污可以避免高密度养殖下硝酸盐氮积累太快;80~610尾/m^3时存活率随密度升高而下降,但产量随密度升高而增加。

从景观体验的角度,探讨滨水工业遗产体验方式的演变,及其对景观设计手法的影响。基于历史研究、类型学和案例比较的方法,提出滨水工业遗产作为城市景观的演进有3个阶段:布景-在场-共享。布景式的如画“景观”与在场式的体验“观景”,是滨水工业遗产景观体验中相互交织的2条重要线索。进入信息时代,虚实交互的“共享”成为滨水工业遗产新的体验方式,改变了空间认知、组织和形式的塑造。通过对景观体验演化的技术驱动、价值转换和空间特征进行剖析,为设计师在处理滨水工业遗产景观体验方式和景观设计方法提供新的思路。
