井下WPT技术机理研究

为解决井下无线传感器电池容量受限的问题,根据井下无线传感器带壮分布的特点,提出了井下无线运动充电的思想.构建充电系统模型,讨论了充电信道建模、接收微带天线设计、多天线协作三个方面的技术路线.本文在研究井下微波输能传输特性的基础上,探讨在低功率密度下,多天线协作的移动无线充电技术在井下运动式充电特性,使用这个技术对无线传感器节点充电,解决井下无线传感器网络能量补充问题,突破现有节点单纯依靠电池供电的局限.     

A Generalization of the Mean Size Formula of Wavelet Packets in Lp

The purpose of this paper is to investigate the mean size formula of wavelet packets in Lp for 0 〈 p ≤ ∞. We generalize a mean size formula of wavelet packets given in terms of the p-norm joint spectral radius and we also give some asymptotic formulas for the Lp-norm or quasi-norm on the subdivision trees. All results will be given in the general setting,     

A New High Efficiency Multiwave Cerenkov Generator Operating at Low Magnetic Field

With a resonant cavity inserted between the second slow-wave-structure section and the tapered wavegulde, a new structure of the multlwave Cerenkov generator (MWCG) operating at low guiding magnetic field is proposed to produce high efficiency and high power microwave. Some features and potential advantages of the proposed device are analysed. The 2.5-dimensional partlcle-in-cell simulation is employed to verify the initial expectation.The results show that, with the use of an electron beam of 640keV and 8.4kA guided by the magnetic lield of 0.6 T, a stable and monochromatic X-band microwave output of 4 GW in peak power is achieved, and the average efficiency is over 30%.     

BEPCII直线加速器相控系统设计研究

宇宙具有十二面体形状

 在从观测宇宙微波背景的Wilkinson微波各向异性探测器(WMAP)获得的数据基础上,美国数学家计算出,宇宙多半最终会具有十二面体形状。进行的是反证法:如果宇宙是无限的,则在微波背景上应观察到任何大小的波,但是实际上不是这样:Wilkinson微波各向异性探测器确实一次也没有观测到巨大的波。根据以杰弗里·威克斯(JeffreyWeeks)博士为首的数学家小组的计算,在宇宙微波背景上的波看上去完全像从规则几何形状十二面体内部看到的一样。其实,其他专家也证实,在其他几何形状内部也能产生类似的波结构。     

Microwave Synthesis, Characterization and DNA-binding Properties of a New Cobalt（ Ⅱ ） Complex with 2,6-Bis（benzimidazol-2-yl）pyridine

A new cobalt(Ⅱ) complex with tridentate ligand 2, 6-bis (benzimidazol-2-yl)pyridine has been synthesized by microwave irradiation method and characterized by elemental analysis,electrochemical and spectral methods. The binding of the complex with calf thymus DNA has also been investigated by absorption and fluorescence spectra.
