Water washing has been regarded as one of the most effective strategies to remove surface residual lithium of nickel-rich layered oxides for lithium-ion batteries(LIBs).However,the loss of lattice lithium during the water washing process deteriorates the electrochemical performances and air ***,washing the LiNi_(0.90)Co_(0.05)Al_(0.02)O_(2)(NCA) with ammonium dihydrogen phosphate(NH_(4)H_(2)PO_(4)) solution has been proposed to simultaneously enhance electrochemical performances and air stability,in which in-situ generated Li_(3)PO_(4) coating layer on surface of NCA can suppress the loss of lattice ***,as a fast ionic conductor,Li_(3)PO_(4) coating layer on NCA can prevent the direct contact with electrolyte/*** a result,the NH_(4)H_(2)PO_(4) solution washed NCA cathode can deliver a high capacity of131.9 mAh·g^(-1) at 10.0C rate as well as impressive cycle stability with a capacity retention of 83.1% after 100 cycles at 1.0C,much higher than those of water washed NCA(WS-NCA) *** exposed in air for 7 days,the NH_(4)H_(2)PO_(4) solution washed NCA electrode can more effectively maintain the structural integrity as well as the electrochemical performances than water-washed *** work provides a simple and effective approach to enhance the cycle stability and air stability of Nickel-rich cathode materials.

现有关于“总体性思想”的研究大都停留在针对卢卡奇的分析与批评上,而没有深入去挖掘“总体性思想”的演进历程。事实上,“总体性”的概念和思想不仅仅只存在于卢卡奇的作品中,而是一直贯穿于包括马克思本人在内的一系列马克思主义理论家的著作中。本文将以卢卡奇的“总体性思想”为出发点,依托西方马克思主义理论进行充分的文本分析,试图发掘西方马克思主义理论中关于“总体性”的思想脉略,从而论析“总体性思想”并不属于卢卡奇个人,而是一种马克思主义的社会分析方法论。“总体性思想”一方面指明了资本主义总体性是如何对无产阶级进行着“支配”,另一方面也揭示了无产阶级实现“自主”的总体性的可能与前进方向。

针对肝脏血管分割方法通常依赖高质量有标签数据训练模型及现存对比学习方法过度关注局部信息而忽略全局信息的问题,提出一种基于全局和局部对比学习的半监督肝脏血管分割方法.本方法首先以Mean Teacher模型作为框架,对编码器输出高维特征进行全局对比,捕捉特征全局一致性,获取更丰富全局上下文信息;然后对解码器输出进行局部对比,获取语义分割中的局部像素级特征;最后引入分布差异最小化方法,通过使用判别器进行对抗训练,减少有标签和无标签数据之间的分布差异,提升模型的泛化性能.实验结果表明:本方法在肝脏血管分割任务上取得了显著的效果,在3Dircadb数据集上的Dice系数、Jaccard系数、平均表面距离(ASD)和95%豪斯多夫距离(95HD)分别为74.36%,59.73%,2.65 mm和13.57 mm,优于其他半监督方法.
