囚禁离子简并混合态的几何相位

讨论了离子阱中简并混合态的几何相位及相干度.计算得出混合态几何相位由演化时间,初态确定以及在离子的作用.另外,我们还计算出在特殊的作用下,几何相位不随离子的初态变化而变化.囚禁离子的高效检测性意味着本文所研究的混合态几何相位能够被验证.

Migration of Cations and Anions in Amorphous Polymer Electrolytes

1 Results Polymer electrolytes are used as ion conductors in batteries and fuel cells.Simple systems consist of a polymer matrix complexing an inorganic salt and are fully amorphous at the temperatures of interest.Both cations and anions are mobile and contribute to charge transport.Most studies on polymer electrolytes use the electrical conductivity to characterize the ion mobility.However,conductivity measurements cannot discriminate between cations and anions.This paper reports some recent results fr...

金属离子和氧化剂对间苯二酚光化学降解的影响

在实验条件下，Mn^2 /Fe^2 /Cu^2 /Zn^2 /Al^3 /La^3 ,KMnO4/K2S2O8/KBrO3/KIO3/KIO4对间苯二酚光化学降解起加速作用，且随浓度增大而增强。KBrO3 Fe^2 ,KIO4 Mn^2 对间苯二酚光化学降解的加速作用更为显著。无光照射时，KMnO4,K2S2O8/KBrO3 Fe^2 ,KIO4 Mn^2 /Fe^2 都能够使间苯二酚立刻发生化学降解，尤其以KMnO4,KIO4 Mn^2 的作用更为显著。     

Possible biological effects of electric and magnetic parameters in the environment

The features and intensities of electric and magnetic fields in the environment are described. Natural as well as technical constant and variable fields are considered in the light of their possible biological effects. The upper limits of the various fields are discussed. Results of laboratory measurements and also of epidemiological investigations are presented. The question is raised whether atmospheric small ions can cause a biological effect.     

THE EFFECT OF TRANSITION METAL IONS-MANGANESE ON HYDROGEN PEROXIDE BLEACHING

INTRODUCTIONHydrogen peroxide bleaching has been extensively used in high-yield pulp bleaching. It is well known that hydrogen peroxide can be decomposed under alkaline conditions, especially when transition metal ions are present. Recent studies showed that valence of transition metal ions is a significant factor in these reactions.Among various transition metal ions, manganese ions are the most harmful species during alkaline peroxide bleaching. Manganese has seven valence electrons (3d…
