‘Qin brick and Han tile’ has a great worldwide reputation in the architectural history of China. According to the former archaeological materials, the big hollow brick is usually one meter long and thirty to forty centimeters wide, while the solid brick is generally much smaller. But in 1995, large scale vestiges and structures were un- earthed at the center of Guangzhou’s old district, from the relic of Nanyue Kingdom Palace, which was built some 2000 years ago during the Western-Han Dynasty. A great number of earthen structural members were discovered, especially the solid glazed bricks in various beautiful patterns with an astonishing thickness and size. Some of them are one meter square, more than 20 centimeters thick, and weight half a ton, which are named ‘Brick No.1 in the world’ by excavators. People have shown great interest in how to make these huge glazed bricks at the ancient tech- nical conditions, because it is very difficult to manufacture such huge bricks even with the modern technology. At the request of Guangdong Nanyue Kingdom Palace Museum, Shanghai Institute of Ceramics carried out systematical measurements and analysis on these bricks and studied the physical and chemical forming mechanisms from their chemical compositions, structure, and physical character- istics. Here the technical characteristics of the bricks are also discussed.

In this work,low-softening-temperature and low-modulus SiO_(2) was introduced as an embedded interface between SiC nanowires(SiCnws)and a Ba_(x)Sr_(1−x)Al_(2)Si_(2)O_(8) ceramic matrix to enhance strength and toughness of the *** the sintering process,molten SiO_(2) enhances the flowability of the ceramic powders and modifies the dispersion of *** strengthening effect of SiCnws was fully realized,and the flexural strength of the optimized ceramics reached 193±16 MPa,which represents an increase of 52.6%.After the formation of the embedded SiO_(2) interface with a low modulus,cracks can deflect along the SiCnws surface,which is consistent with the criterion of He and *** can effectively extend the crack propagation path,and the fracture toughness(K_(IC))is thus improved by 94.0%,reaching 3.1±0.5 MPa·m^(1/2).

The application of semiconductor materials was limited as electromagnetic absorption materials,due to the unstable absorption performance caused by the temperature *** this work,a structurally controllable ceramic heterojunction was developed by assembling structural units of SiC nanowires(SiCnws)and Ba_(0.75)Sr_(0.25)Al_(2)Si_(2)O_(8)(BSAS).Benefiting from the optimization of the energy gap and the construction of heterogeneous interfaces,the ceramic heterojunction can achieve stable electromagnetic absorption from room temperature to 600℃,the effective absorption bandwidth is almost *** the minimum reflection loss value reached-63.6 dB at 600℃.Meanwhile,the SiCnws/BSAS ceramic heterojunction shows stable electromagnetic absorption performance in various simulated outdoor environments,including acid rain,seawater,high temperature and water vapor *** result provides a fire-new idea to realize the environmental adaptability of electromagnetic absorption materials and largely broadens its application prospect.

针对临近空间跳跃滑翔目标运动建模困难,跟踪精度低的问题,提出了一种基于自适应衰减震荡模型的轨迹跟踪方法。首先,对临近空间滑翔跳跃目标的运动特点进行了深入分析,确定其运动具有周期性和衰减性的特点;根据这一特点,利用二阶时间自相关随机过程对加速度和飞行路径角进行建模,通过傅里叶变换推导了零均值衰减震荡模型;考虑到临空目标受气动阻力的作用,加速度小于零的情况,借鉴“当前”统计模型的思想,进一步对零均值衰减震荡模型进行改进,提出了自适应衰减震荡模型,实现了目标运动描述在周期性和衰减性上的统一。在此基础上,建立了地理坐标系下的目标运动模型,给出了基于雷达的测量模型。针对该系统非线性较强的特点,利用无迹卡尔曼滤波算法完成了跟踪滤波器的设计。仿真结果表明,所提出的算法具有更好的跟踪效果,其位置跟踪精度和速度跟踪精度较正弦波模型分别提高了17.91%和26.33%。

2004年,五代时期南汉国德陵和康陵在广州小谷围岛的考古发掘中得以确认,出土了数量较多的瓷器和釉陶器,为广东地区五代陶瓷史的研究提供了大量的实物依据,该项发掘入选"2004年度全国十大考古新发现"。通过对广州市文物考古研究所提供的发掘出土的部分陶瓷标本的化学组成、物理性能、显微结构等的测试与分析,并通过与广东本地窑口和浙江越窑的对比研究,对这批陵墓出土器物的来源、特点和烧制工艺等进行了深入探讨。结果表明:这些器物大多数为广东本地的产品,但同时也发现个别器物可能来自于越窑。不同类别的器物所用原料存在差别,说明当时的陶工对原料具有明显的选择性。此外,还对釉陶器表面"银釉"的产生机理和其它相关问题进行了讨论。
