New types of hyper MV‐deductive systems in hyper MV‐algebras

The notions of a (weak) hyper MV‐deductive system, a (?, ?; ?)‐hyper MV‐deductive system, a (?, ?; ?)‐ hyper MV‐deductive system, a (?, ?; ?)‐hyper MV‐deductive system, a (?, ?; ?)‐hyper MV‐deductive system and a (∩, ∩; ∩)‐hyper MV‐deductive system are introduced, and then their relations are investigated (© 2010 WILEY‐VCH Verlag GmbH & Co.

超光谱成像仪中棱镜的热光谱特性

为了确定超光谱成像仪热控指标和开展热设计,研究了超光谱成像仪中棱镜的热光谱特性。介绍了超光谱成像仪的工作原理以及热光谱特性的含义,分析了棱镜的环境热效应,论述了棱镜热光谱特性研究内容及技术路线,推导了温度变化时棱镜偏转角以及角色散的函数关系,进一步得到光谱中心平移及光谱带宽随温度变化规律。借助有限元分析,比较了K9、熔石英两种材料的棱镜的入射角、顶角、材料色散、光谱中心平移及光谱带宽随温度变化规律,确定了棱镜的热控指标,并设计了热光谱试验。理论分析和试验结果表明由于热变形引起的光谱带宽和光谱分辨率改变可以忽略不计,光谱平移主要由材料折射率温度系数决定;棱镜材料色散(dn/dλ)对温度变化不敏感,因此温度变化对其光谱带宽影响不明显; 本文研究方法合理,结果可信,对确定棱镜的热控指标和优化热设计具有指导意义。     

A novel macroinimer of polyethylene oxide: synthesis of hyper branched networks by photoinduced H-abstraction process

A novel poly(ethylene oxide) macroinimer (PEO-macronimer) possesing methacryloyl and tertiary amino end groups was prepared by ring-opening polymerization of ethylene oxide initiated by potassium 2-methylaminoethoxide and termination of living ends of PEO with methacryloyl chloride. NMR analysis showed that the macronimer contains equal amount of amino and methacrolyl groups indicating efficient initiation and termination processes. The dimethylamine end group in conjunction with benzophenone under UV irradiation produced ternary amine methylene radicals via H-abstraction mechanism which initiates the polymerization. Photopolymerization in solutions at high macroinimer concentration or in films resulted in the formation of insoluble networks. The crosslinked polymers exhibit high swelling capacity in organic solvents and water due to the hyperbranched nature.     

Integrals of psi—function

To the author's knowledge, among the so—called special functions, the gamma function is a unique one which is defined by a linear difference equation and is a hyper—transcendental function. There exists an another well—known hyper—transcendental function called the psi function, which is merely the logarithmic derivative of the gamma function. In this paper the author consider an extension of the gamma function and then obtain a series of integrals of the psi function.
