Ceramic electrolytes are important in ceramic-liquid hybrid electrolytes(CLHEs),which can effectively solve the interfacial issues between the electrolyte and electrodes in solid-state batteries and provide a highly efficient Li-ion transfer for solid–liquid Li metal *** the ionic transport mechanisms in CLHEs and the corresponding role of ceramic electrolytes is crucial for a rational design ***,the Li-ion transfer in the ceramic electrolytes of CLHEs was confirmed by tracking the 6Li and 7Li substitution behavior through solid-state nuclear magnetic resonance *** ceramic and liquid electrolytes simultaneously participate in Li-ion transport to achieve highly efficient Li-ion transfer in CLHEs.A spontaneous Li-ion exchange was also observed between ceramic and liquid electrolytes,which serves as a bridge that connects the ceramic and liquid electrolytes,thereby greatly strengthening the continuity of Li-ion pathways in CLHEs and improving the kinetics of Li-ion *** importance of an abundant solid–liquid interface for CLHEs was further verified by the enhanced electrochemical performance in LiFePO4/Li and LiNi0.8Co0.1Mn0.1O2/Li batteries from the generated *** work provides a clear understanding of the Li-ion transport pathway in CLHEs that serves as a basis to build a universal Li-ion transport model of CLHEs.

疑问代词“谁”“什么”“哪里”的指称性质需要根据它们出现的语境来分析,这包括句法位置和句子情态。文章分析了“谁”“什么”“哪里”在这两种语境中的指称性质,对“谁”“什么”“哪里”的指称对象做出细致的解读,有助于准确地理解句子的意义。文章还区分了指称功能与指称性质,认为前者是所有名词的词位都具有的,是潜在的,而后者则是名词的词位变体在具体语境中表现出来的,有相同指称功能的名词可以有不同的指称性质。

Journal of Materials Science & Technology 2001年第4期17卷 457-459页

作者： hongqi LI, Yanbin wang and Wuyang CHU Dept. of Materials Physics & Chemistry, University of Science and Technology Beijing, Beijing 100083, China Dept. of Mat. Phys. and Chem. Univ. of Sci. and Technol. Beijing Beijing 100083 China

Using a special constant deflection device, the changes in dislocation configuration ahead of a loaded crack tip for 60Fe40Ni alloy. before and after magnetization in a magnetic field, have been studied in TEM. The results showed that the magnetization for 60Fe40Ni alloy could enhance dislocation emission, multiplication and motion. Also, the mechanical properties of 60Fe40Ni alloy, in air and in the magnetic field respectively have been investigated using the slow strain rate tension. And the results indicated that magnetization could make the yield strength corresponding to decrease by 26 percent, but did not influence the ultimate tensile strength and the fracture strain, which showed that magnetization could enhance plastic deformation.
