The polymeric gel electrolytes are attractive owing to their higher ionic conductivities than those of dry polymer electrolytes and lowered water activity for enlarged potential ***,the ionic conductivity and mechanical strength of the Na-ion conducting polymeric gel electrolytes are limited by below 20 mS cm−1 and 2.2 ***,we demonstrate Na-ion conducting and flexible polymeric hydrogel electrolytes of the chemically coupled poly(diallyldimethylammonium chloride)-dextrin-N,N′-methylene-bisacrylamide film immersed in NaClO_(4) solution(ex-DDA-Dex+NaClO_(4))for flexible sodium-ion hybrid capacitors(f-NIHC).In particular,the anion exchange reaction and synergistic interaction of ex-DDA-Dex with the optimum ClO_(4)−enable to greatly improve the ionic conductivity up to 27.63 mS cm−1 at 25◦C and electrochemical stability window up to 2.6 V,whereas the double networking structure leads to achieve both the mechanical strength(7.48 MPa)and softness of hydrogel ***,the f-NIHCs with the ex-DDA-Dex+NaClO_(4) achieved high specific and high-rate capacities of 192.04 F g^(−1)at 500 mA g^(−1)and 116.06 F g^(−1)at 10000 mA g^(−1),respectively,delivering a large energy density of 120.03Wh kg^(−1)at 906Wkg^(−1)and long cyclability of 70%over 500 cycles as well as demonstrating functional operation under mechanical stresses.

The Kinematic Theory of Solar Dynamo

引用

Chinese Journal of Astronomy and Astrophysics 2003年第1期3卷 12-32,i001页

作者： Ke-Ke Zhang and Xin-hao LiaoSchool of Mathematical Sciences, University of exeter, ex4 4QE, UK kzhang@ex.ac.ukShanghai Astronomical Observatory, Shanghai 200030 xhliao@*** School of Mathematical Sciences University of Exeter EX4 4QE UK Shanghai Astronomical Observatory Shanghai 200030 China

Generation of the Sun's magnetic fields by self-inductive processes in the solar electrically conducting interior, the solar dynamo theory, is a fundamentally important subject in astrophysics. The kinematic dynamo theory concerns how the magnetic fields are produced by kinematically possible flows without being constrained by the dynamic equation. We review a number of basic aspects of the kinematic dynamo theory, including the magnetohydrodynamic approximation for the dynamo equation, the impossibility of dynamo action with the solar differential rotation, the Cowling's anti-dynamo theorem in the solar context, the turbulent alpha effect and recently constructed three-dimensional interface dynamos controlled by the solar tachocline at the base of the convection zone.

Rapid manufacture of Ni-based superalloy components by three-dimensional printing

引用

中国有色金属学会会刊：英文版 2006年第A3期16卷 1901-1905页

作者：刘建新 H.A.KUHN ProMetal Division The Ex One Company8075 Pennsylvania AvenueIrwinPA 15642USA

The challenge to rapid manufacturing high performance metal components is how to consolidate the uncompressed powder preforms to full or near full density without shape distortion. A new approach developed by ProMetal was proposed, in which a bimodal powder, typically a coarse prealloyed powder blended with a fine metal powder was used to build green preforms by three-dimensional printing and then sintered at a temperature above the solidus temperature of the coarse prealloyed powder and below the melting temperature of the fine powder particles or the solidus temperature if the fine powder is a prealloyed powder as well. This approach was successfully applied to sinter Ni-based superalloy 718 preforms, which were built through three dimensional printing into near full density.

China's Foreign Trade 1996年第9期 12-13页

作者： Tian YimingThe ex-publisher and editor-in-chief ofChina’s Foreign Trade

In December 1958, the China Council forthe Promotion of InternationalTrade(CCPIT) established its PublicityDepartment. Its task was to take over themagazine China’s Foreign Trade, transferredfrom the Ministry of Foreign Trade. Ms. LuJiyin held the post of department head, and Iwas transferred from the post of the ResearchDepartment Commissioner to that of thePublicity Department Commissioner to assisther in her work. The magazine China’s Foreign Tradewas originally established in 1956 by thePropaganda Section under the General Officeof the Ministry of Foreign Trade. It had twoeditions: Chinese and English, under trialpublication. The magazine, sponsored by theMinistry of Foreign Trade was a trialpublication in nature, so when the task
