以技艺理论发展为经,复制技术嬗变下的图像表征为纬,艺术视觉研究呈现显学之势。处于摄影机时代的本雅明开启“机械复制时代”的学术话域,而技艺关系在鲍德里亚关于技术物、符号性、区分秩序讨论框架中得到进一步展望。艺术的技术复制问题关乎技术基础、艺术特质、艺术主体等线索维度,在本雅明到鲍德里亚的语域转换中,从机械复制跃进到拟像仿真,人们的灵韵膜拜情结悄然转变为技术拜物,技术命定主体取代能动现代主体。本雅明和鲍德里亚有关技术复制的思想揭示了当代艺术正加速图像转向的现实样态,描摹了艺术图像化对人类知觉形式、思考方式、感知方式和审美方式的重构境况,但仍存在对物化方式与审美意涵的两极割裂,对技术本身和审美主体的关系误读,对艺术存在采取消极的宿命策略等逻辑裂缝。

Plants sense neighbor proximity as a decrease in the red to far-red ratio of incoming light,which triggers a series of developmental responses known collectively as the "shade avoidance syndrome"(SAS).In Arabidopsis thalianu,phytochrome B is the major sensor of shade light,but to date phytochrome excitation has not been linked directly to a growth response. We show that the bHLH transcription factor,PIF7,previously shown to interact with phytochrome B,accumulates in its dephosphorylated form in shade,allowing it to bind to the promoters of a subset of auxin biosynthetic genes and increase their *** new auxin is required for changes in growth in the shade,our studies link directly the perception of a light quality signal to a rapid growth *** are also working on a most shade induced gene PIL1 and find PIL1 protein accumulates after shade treatment and PIL1 overexpression attenuates expression of many shade-induced ***,PIL1 protein represses PIL1 expression to form a self-limiting feedback ***,PIL1 is a negative regulator of the shade-induced transcriptional response in Arabidopsis.

The existence of global weak solutions for a generalized benjamin-Bona-MahonyBurgers equation is established in the space C（[0, ∞） × R） ∩ L~∞（[0, ∞）; H1（R）） under the condition that its initial value belongs to the space H1（R）. A one-sided super bound estimate and a space-time higher-norm estimate on the first order derivatives of the solution with respect to the space variable are derived to prove the existence.

Long time series of wave field are experimentally simulated by JONSWAP spectra with random phases in a 2D wave flume. Statistic properties of wave surface, such as significant wave height, skewness and kurtosis, are analyzed, and the freak wave occurrence probability and its relations with benjamin-Feir index （BFI） are also investigated. The results show that the skewness and the kurtosis are significantly dependent on the wave steepness, and the kurtosis increases along the flume when BFI is large. The freak waves are observed in random wave groups. They occur more frequently than expected, especially for the wave groups with large BFI.

在西非的象牙海岸Issia地区分布着许多铌钽矿床,包括原生矿和砂矿。原生矿产在分带很好的伟晶岩中。这个地区发育着许多花岗岩和花岗伟晶岩。伟晶岩可分为:(1)分异不好的伟晶岩,无矿化;(2)含Be伟晶岩,分带较好,见绿柱石;(3)含Be-Nb-Ta的伟晶岩,分带很好,是矿体;(4)Be-Nb-Ta-li伟晶岩,分带很好,是矿体。除了10多个原生矿外,还有许多砂矿。砂矿有两种类型:一种近原生矿的坡积砂矿,另一种是经河流冲刷搬运后的冲积砂矿。我们选择了Etienne-Meguhe砂矿作为近原生矿的坡积砂矿的代表,Bemadi矿作为河流冲积型的砂矿的代表,对这两种类型的砂矿的风化、搬运、沉积机理进行了比较研究。研究发现不同的搬运距离和搬运模式对铌钽砂矿的主要矿物——铌钽铁矿的化学性质没有什么影响,而其物理形态则发生了变化。坡积型砂矿的铌钽铁矿常与石英、长石等矿物连生,其颗粒大小与原生的Nb-Ta伟晶岩中的铌钽铁矿一致;经河流冲积而形成的砂矿中,铌钽铁矿颗粒变小、轮廓变得圆滑,几乎无连生矿物,但矿体集中,常在河流的冲积扇中分布,易开采。
