Abstract: 喀斯特石漠化是近年来所认识到的一种地质生态灾害，是脆弱生态环境和不合理人类活动的共同产物。本文阐述了砚山县石漠化现状和危害，从岩性、地貌、降水和超载的人口压力分析了该县石漠化产生的原因，并结合当地实际情况讨论该县在石漠化治理过程中存在的一些问题，并提出解决对策。
Karst rocky desertification has been recently regarded as a kind of geological-ecological disaster, which was caused by both fragile ecological environment and improper human activities. This paper expounds the present situation and hazard of rocky desertification in Yanshan County, and analyzes the causes of the county rocky desertification from the lithology, topography, precipitation, and the excess of population pressure, then discusses some problems existing in the rocky desertification process in the county combined with the actual conditions, finally solutions to countermeasures are proposed.

Abstract:
粗粒度可重构体系结构由于其配置速度快、计算加速比高、适应性好、低功耗特性等优点已成为高性能可重构SoC协处理器的重要解决方案。可重构SoC的性能分析，普遍使用传统的寄存器传输级代码仿真分析方法，存在使用不方便、分析效率较低等不足之处。本文提出一种基于事务数据流图的可重构SoC性能分析方法，该方法结合应用程序数据流图与体系结构特征，构建可重构协处理器的事务数据流图并标注图节点功能属性相应的硬件性能参数；然后采用基于层次搜索的广度优先性能搜索算法，通过分析类树形结构的事务数据流图，得到可重构协处理器运行应用程序的性能分析结果。实验表明所提出的方法可以较为准确高效的分析可重构SoC体系结构应用计算性能，有助于可重构SoC早期体系结构设计和设计空间探索。
Coarse grained reconfigurable architecture has become an important solution for high performance re-configurable SoC coprocessor because of its high configuration speed, fast calculation speed, good adaptability and low power consumption. However, the traditional performance analysis method of register transfer level modeling is still widely used. To overcome the shortage of traditional performance analysis in flexibility and efficiency, we propose a new method for reconfigurable SoC performance analysis based on transaction data flow graph. This method combined application data flow graph with architectural characteristics through constructing the transaction dataflow graph of reconfigurable coprocessor and labeling hardware performance parameters corresponding to functional properties. Using the breadth first search algorithm based on hierarchical search to analyze the tree-like transaction dataflow graph, we can get the performance of reconfigurable coprocessor running applications. The result of the experiment indicates that the proposed method calculates the structure of the reconfigurable SoC quite accurately, and benefits the design of architecture and design space exploration.
基于正弦载波的粒子群算法
庄敏慧,王振雷,钱锋
华东理工大学学报 , 2009,
Abstract: 针对传统粒子群算法(TraditionalParticleSwarmOptimization,TPSO)存在的易陷入局部最优、收敛速度慢等缺点，提出了一种基于载波的粒子群算法(carrier-waveParticleSwarmOptimization，CWPSO)。根据正弦函数具有的自变量连续变化而值域不变的特点，该算法设计了以载波自变量变化确定粒子搜索位置的新方法，从而极大地提高了全局搜索能力。同时对于搜索到的可能极值点，通过载波扩展的方法进行局部寻优，以进行精确搜索。对一系列测试函数的寻优结果表明：CWPSO算法不仅都能找到最优值，且寻优时间仅为TPSO算法和惯性权值线性下降的改进PSO算法（Line-WPSO，LWPSO）的1/3~1/5；同时，CWPSO具有对寻优问题维数不敏感的优点，大大扩展了该算法的适用范围。

电子与信息学报 , 2003,
Abstract: Wide swath SAR is a hotspot of the research of SAR (Synthetic Aperture Radar). In many fields of SAR application which require global and dynamic surveillance or frequent surveillance of a certain part of the earth surface, it is expected that the swath of SAR is much more wider. A new method of wide swath SAR based on multiple modulation mode is presented in this paper. The selection of modulation mode, the solution to the problem of blind zone, and the data processing method of this system are discussed.
THE SPECTRAL ANALYSIS OF NON-LINEAR CODING COMPRESSED RAW DATA OF SYNTHETIC APERTURE RADAR

电子与信息学报 , 2001,
Abstract: In this paper, a spectral analysis method is presented to assess the quality of Synthetic Aperture Radar(SAR) image whose raw data is non-linear coding compressed. Usually, it is assumed that the SAR raw data compression will result in the reduction of Signal to Noise Ratio(SNR), and the image quality is therefore degraded, but the resolution of image is not reduced. By means of the spectral analysis method in this paper, it is demonstrated the SAR data frequency spectrum is not reduced after the compression, and the SAR image resolution is retained. The effects of distortion resulted from the data compression is also analysed.

动物学研究 , 1982,
Abstract: 近年我国从事生物防治的科技人员和广大社员,利用赤眼蜂大面积防治多种农业和林业害虫于卵期,取得良好效果。关于赤眼蜂在自然界中利用何种昆虫卵作为其越冬寄主卵,以及这些寄主卵的显微结构特征,迄今未见任何系统报道。经野外调查证实,杨雪毒蛾(即柳毒蛾)卵、茶白毒蛾卵、蔚茸毒蛾卵和茶茸毒蛾卵是赤眼蜂的四种越冬寄主卵、它们皆属鳞翅目的毒蛾科。 本文首次报道利用扫描电子显微镜,观察这四种毒蛾卵的结构特征,并探讨其被赤眼蜂产卵寄生,在其中越冬的问题。
