In this study, a lithium-rich 0.4Li2MnO3.0.6LiNi1/3Co1/3Mn1/3O2 nanotube layered cathode synthesized by novel electrospinning is reported, and the effects of temperature on the electrochemical performance and morphologies are investigated. The crystal structure is characterized by X-ray diffraction patterns, and refined by two sets of diffraction data （R-3m and C2/m）. Refined crystal structure is 0.4Li2MnO3.0.6LiNi1/3COl/3Mn13O2 compos- ite. The inductively coupled plasma optical emission spec- trometer and thermogravimetric and differential scanning calorimetry analysis measurement supply reference to opti- mize the calcination temperature and heat-treatment time. The morphology is characterized by scanning and high- resolution transmission electron microscope techniques, and the micro-nanostructured hollow tubes of Li-rich 0.4Li2MnO3-0.6LiNil/3COl/3Mn1/3O2 composite with outer diameter of 200-400 nm and the wall thickness of 50-80 nm are synthesized successfully. The electrochemical evaluation shows that 0.4Li2MnO3.0.6LiNi1/3Cov3Mn1/3O2 sintered at 800 ℃ for 8 h delivers the highest capacity of the first dis- charge capacity of 267.7 mAh/g between 2.5 V and 4.8 V at 0.1C and remains 183.3 mAh/g after 50 cycles. The electro- spinning method with heat-treatment to get micro-nanos- tructured lithium-rich cathode shows promising application inlithium-ion batteries with stable electrochemical performance and higher C-rate performance for its shorter Li ions transfer channels and stable designed structure.

足球场场地作为足球运动的基础,其质量直接影响到比赛的竞技性和观赏性。目前国际上的各类足球场评价体系都是基于"通过式分级评价"或"平均重要性指标"进行评价的。本研究通过总结国内外足球场评价的相关标准和书籍,整理和筛选出足球场质量评价的指标和指标的分级阈值。通过调查专家、足球运动员、足球爱好者对指标的认知重要程度,发现3类受调查者对于各指标的认知重要性有较明显差异,但对于一些场地质量核心指标却有相似的认知程度和趋势。这证明了传统的平均重要性假设或通过性评价的方式其评价和分级的方法是不客观的。将各类场地使用者对评价指标认知重要性引入评价体系并建立足球场场地质量评价,可以很好地解决评价场地不够客观的问题,可以更好地了解使用者对场地的需求,从而更好地建设和管理足球场场地,使我国足球场场地质量评价体系更具有科学性和实用性,使草坪质量更能满足场地使用者的需求。
