新型粉末状荧光502熏显手印荧光波段研究

目的运用新型粉末状荧光502可一步显现非渗透性光滑客体表面潜手印。为了选择最佳的激发光源和滤光镜来观察熏显后荧光效果,本文对该粉末的荧光性能进行研究。方法使用荧光光谱仪对新型粉末状荧光502进行激发光谱和发射光谱的测试,进而选择合适的激发光源及滤光镜来进行观察和拍照。结果新型粉末状荧光502的光谱范围较宽,在波长为235nm~580nm范围内均可进行激发,具有广谱性,其中对波长在530nm附近的激发光具有最大峰值,即荧光强度最大,对450nm和360nm附近的光也具有很高的吸收峰值,斯托克斯偏移量为45nm。宏观验证实验表明,在仪器分析所得的范围内,显现出的手印效果均较好。结论运用该粉末在熏显手印后可以在紫外、紫光、蓝光、黄光、绿光范围内进行激发,斯托克斯偏移大,荧光亮度高,在观察荧光效果时能够很好的消除背景荧光的干扰,也便于选择滤光镜。手印荧光效果除了受到熏显物质荧光性能的影响外,还与激发光源的品质、滤光片的透过性能以及检材固有的发光特点、客体表面性质有关。     

Analysis of Policy of Investment in Science and Technology Based on CGE Model

Investment in science and technology is not only a significant indicator to reflect a regional scientific and technological strength and core competitiveness, but also important to technical progress and technology innovation. Investment in science and technology will affect the entire economy through technology innovation. In this paper, it analyzes the impact of Beijing investment in science and technology on regional economic development and builds a Beijing regional CGE （Computable General Equilibrium） model with an econometric module that links the investment in science and technology with technological progress. It finds that investment in science and technology will increase the Beijing GDP （Gross Domestic Product）, and promote economic structural adjustment. When the real investment in science and technology increases 1%, 2%, or 3%, Beijing GDP will respectively increase 0.93%, 1.22%, or 1.51%. From the perspective of resident＇s income, when investment in science and technology increase by 3%, the level of resident＇s income will increase by 3.24%. In view of the structure perspective of different sector＇s investment in science and technology, different investment in sectors will lead to different impact of economic growth and structure; results show that： when the priority of Beijing investment of different sector in science and technology is tertiary sectors, agricultural sector, and industry sectors, it is conducive to economic growth and industry structure adjustment.     

马克思主义作为信仰的四重意蕴

马克思主义作为信仰至少有四重意蕴,并且表现出自在的内在逻辑:马克思主义信仰因其自身科学性,进入信仰者视野作为信仰选择,并通过知、情、意三个因素映射出信仰心态,但是作为一种世俗信仰,在党员和公民不同主体之间有规范性与个人伦理选择的区别,对于共产党员来说,坚定马克思主义信仰是其党性的根本要求和体现.

Chinese Enterprises in Laos and Cambodia

In recent years there has been a rapid increase in Chinese enterprises investing in Laos and Cambodia. However, this increase has drawn both praise and criticism. Praise is mainly concerning Chinese enterprises＇ efforts to support local development, and their assistance in achieving power-sufficiency in power generation and stabilizing domestic prices. Criticisms, which mainly concentrate on their lack of transparency, environmental awareness, and communication with local communities, reflect the challenges Chinese companies face in going global. To address these criticisms, the Chinese government needs to strengthen their oversight capacity with respect to Chinese overseas enterprises and help them develop an awareness of corporate social responsibility （CSR）. Enterprises themselves should improve their overseas image by internalizing the idea of CSR in their business model, and interacting more with local communities and NGOs.
