Studies on the Marine Management System in the Philippines
近年来,中菲围绕南海主权争议不断,尤其是“黄岩岛对峙事件“和“台湾渔民被射杀事件“严重影响了中菲关系,但从另一方面也反映了菲律宾加强海洋管理和海洋执法管理的事实。为了避免此类事件再次上演,维护我国海洋权益,本文试图对菲律宾的海洋管理政策、海洋立法、海洋执法管理以及与之相关的管理体制等多方面的管理制度进行研究、评析,并期望对我国加强海洋管理有所借鉴。In recent years,sovereignty dispute over the South China Sea between China and the Philippines has been continuing,especially the "Huangyan Island confrontation"and "Taiwanese fishermen were shot"have seriously affected Sino-Philippines relation.But on the other hand,it also reflects a fact that the Philippines strengthens the Marine Management and Marine Law Enforcement Management.In order to avoid such incidents happening again,and to maintain China's maritime rights and interests,this article attempts to study and analyse the marine management policy,maritime legislation,marine law enforcement management as well as related management system in the Philippines which can give some enlightenments on our marine management.国家社科基金项目“东盟主要成员国海洋战略研究”(11XGJ011); 广西社科规划项目“东盟国家海洋权益意识及广西海洋资源开发对策研究”(11FGJ003

LED Color Analysis
主要对蓝光、绿光、白光lEd的色度特性进行分析,首先通过单色仪,分别测得蓝光、绿光、白光lEd的相对光谱功率分布并以色度学理论为基础,计算出光源主波长、色纯度、色温和显色指数.计算结果表明:蓝光lEd和绿光lEd主波长随标准光源的不同变化不大,色纯度比较高,分别在0.64和0.87左右,一般显色指数为-29和-14,显色性很差,不适合用来做照明光源.白光lEd主波长随标准光源的不同变化较大,色纯度相当低,接近0,一般显色指数为82,显色性很好,完全符合照明光源的要求.In order to study the color characteristics of light-emitting diode,the characteristics of blue,green and white LED colors are analyzed.Firstly,the spectral power distribution of blue,green,white LED is respectively measured by using the monochromator,and then on the basis of the theory chroma,the main light source wavelength,color purity,color temperature and color rendering index are calculated.The results show that blue LED and green LED dominant wavelengths change little with different standard light sources,and the color purities are relatively high,at 0.64 and 0.87,respectively,the general color-rendering is very poor for the index of-29 and-14,so these blue and green LED are not suitable to be used as lighting source.White LED dominant wavelength largely change with different standard light sources,and color purity is relatively low,near 0,color rendering is good for the general color-rendering index of 82, so white LED is in full conformance with the lighting requirements
Study of Deep-level Fine Structure by Laplace Defect Spectroscopy
用Laplace缺陷谱仪 (LDS)实验研究了GaAsP中Fe深受主上空穴发射和AlGaAs中SnDX中心上电子发射引起的非指数瞬态 ,发现它们起因于混晶无序效应。与DLTS的单一谱峰比较 ,LDS谱呈现出多峰结构。由深能级上空穴与电子热发射率随温度关系的直线拟合 ,得到多峰结构各峰谱的激活能 ,认为它们反映杂质深中心与其近邻原子的不同结构。研究表明 ,LDS适用于深能级精细结构的研究。A Laplace defect spectrometer (LDS) is applied to study non exponential transients resulting from hole emission from Fe related deep acceptors in GaAsP and electron emission from Sn related DX centers in AlGaAs. The non exponential transients which bear a relationship to the alloy random effect are investigated under different conditions. Their LDS spectra exhibit several well resolved sharp peaks assigned to the fine structures of the Fe related deep acceptors and the two DX centers, respectively. The activation energies of the fine structures are determined by linear fitting of the slopes of temperature dependences of hole and electron emission rates. The results show that the LDS is useful for investigation of deep level fine structures.国家自然科学基金资助项目 (6 9976 0 2 3) ;; 福建省自然科学基金资助项
Investigation of Porous Silicon/Carbon Composite as Anodes for Lithium Ion Batteries
以商业化多晶硅粉为原料,采用金属银催化剂诱导化学腐蚀的方法制得三维多孔硅材料。通过优化腐蚀条件,得到孔径约为130 nM,比表面为4.85 M2/g的多孔硅材料。将多孔硅和PAn溶液混合球磨并经高温烧结后在多孔硅表面包覆上一层致密的无定形碳膜,从而制得多孔硅/碳复合材料作为锂离子电池的负极材料。3d多孔硅结构可以缓解电化学嵌/脱锂过程中材料的体积效应,无定形碳膜层可有效改善复合材料的导电性能。电化学性能测试表明,该多孔硅/碳复合负极材料电池在0.4 A/g的恒电流下,首次放电容量3345 M AH/g,首次循环库伦效率85.8%,循环55次后容量仍保持有1645 M AH/g。并且在4 A/g的倍率下,容量仍维持有1174 M AH/g。该方法原料成本低廉,可规模化生产。3D porous silicon was synthesized by metal-assisted chemical etching process using commercially available polycrystalline silicon powders.After chemical etching in optimized solution, 3D porous silicon structures with pore size of about 130 nm and specific surface area of about 4.85 m2/g was obtained.Subsequently, the 3D porous silicon powders treated with ball milling and heat carbonization processes were coated with amorphous carbon and utilized as the anode electrode material for lithium ion battery.The combination of the 3D porous structure and a carbon coating layer can accommodate large mechanical strains by providing the empty space of the pores to alleviate the volume change, and by increasing the electrical conductivity with the carbon layer.The electrodes achieve an initial charge capacity of 3345 m Ah/g with coulombic efficiency of 85.8% as well as a high reversible capacity of 1645 m Ah/g after 55 cycles at 0.4 A/g.And it is capable to retain a capacity of 1174 m Ah/g even at 4 A/g.Thus, this work introduces a novel and easy potential industrial method for fabrication Si/C materials for high-performance lithium ion battery.国家自然科学基金(61176050;21233004)~
