Abstract For forty years, there has been a widely held belief that over 2,000 years ago the Chinese Qin developed an advanced chromate conversion coating technology (CCC) to prevent metal corrosion. This was based on detection of chromium traces surface bronze weapons buried with Terracotta Army, and same weapons’ very good preservation. We analysed weapons, lacquer soils from site, conducted experimental replications CCC accelerated ageing. Our results show presence is correlated artefact...
Structure-from-motion and multiview-stereo together offer a computer vision technique for reconstructing detailed 3D models from overlapping images of anything large landscapes to microscopic features. Because such can be generated ordinary photographs taken with standard cameras in lighting conditions, these techniques are revolutionising digital recording analysis archaeology related subjects as palaeontology, museum studies art history. However, most published treatments so far have...
A polyacrylonitrile‐based carbon fiber was electrochemically oxidized in an aqueous ammonium bicarbonate solution with current density of up to 2.76 A/m 2 at room temperature. X‐ray photoelectron spectroscopy revealed that the oxygen content increased increasing before approaching saturation. The increase can be divided into two regions, rapid region (0–1.78 ) and a plateau (1.78–2.76 ). surface chemistry analysis showed interlaminar shear strength (ILSS) value fiber/epoxy composite could...
At the heart of bureaucratic practice during Warring States and early Imperial China were regular, small acts accountancy in which objects people marked so that their movements could be kept track of, quality checked numbers marshalled. In mausoleum complex Qin Shihuang (259-210 bc, First Emperor Dynasty), longer texts shorter inscribed marks found on bronze weapons Terracotta Army are reasonably well known, such information helps us to understand aspects craft organisation logistics at this...
In this paper, we study \lambda-biharmonic hypersurfaces in the product space L^{m}\times\mathbb{R}, where L^{m} is an Einstein and \mathbb{R} a real line. We prove that with constant mean curvature L^{m}\times\mathbb{R} are either minimal or vertical cylinders, obtain some classification results for \lambda$-biharmonic under various constraints. Furthermore, investigate L^{m}(c)\times\mathbb{R}, L^{m}(c) form sectional c, categorize totally umbilical semi-parallel.

摘要: 为了解决随机成分多、调节灵敏度高的离轴反射式系统的精确装调问题，介绍了干涉测量与计算机优化技术相结合的方法，建立了各元件失调量与初级像差之间的关系，以及元件间的像差相互补偿关系，通过干涉测量采集系统全视场的波前差，反向优化得到各元件的失调量，在波长为632.8 nm时，无焦压缩光路系统全视场平均出射波前优于RMS0.055 ，压缩比误差小于5，实现了无焦压缩光路系统高精度、高效率的装调。 关键词: 遥感 / 计算机辅助装调 无焦压缩光路系统 灵敏度矩阵
The dynamic characteristics of the Van der pol system with delay are investigated in this paper. By substituting variables, characteristic equations obtained. stability trivial equilibrium is discussed by analyzing distribution roots equations. If instable on points, should meet equation Re (λ) =0, from which, result to got and critical values found. It found that Hopf bifurcation occurs when passes through values, then their relations parameters adding delays change motion forced vibration...
