[求助] 求助翻译一段话

球磨的样品存在几纳米厚的玻璃态表面结构可以从文中图1d和图4d得到证明。从图1d,样品的高分辨电镜图上可以看出:样品是一个核壳结构的复合材料,内核为结晶性良好的钛酸锂,(对应层间距为0.45nm),在钛酸锂的表面有一层几个纳米厚的非晶玻璃态包覆层。
我们认为这层物质为氮化钛,这是在球磨的过程,经过高能球磨在钛酸锂的表面生成了非晶的氮化钛层。存在这样一个结构也可以从图4d原料钛酸锂和球磨后的样品首次充放电曲线得到证明,从充放电曲线可以看出球磨后单相区有所增加,按照Park和Zhou的观点增加的单相区是因为钛酸锂晶体的表面修饰,正是增加的单相区使其电化学性能有所提高。

The structure of glassy-state surface in several nanometers thickness could result from fig. 1d and fig. 4d of ball-milled samples. We can conclude from the HTEM electron micrograph in fig. 1d that the sample is a core-shell composite whose core is well-crystalized lithium titanate (the interlamellar spacing is 0.45nm) covered by a several nanometer thickness non-crystal glassy layer. We suppose that the layer is consisted of titanium nitride, just because during the ball-milling procedure, non-crystal titaniun nitride generates on the surface of lithium titanate. Surely this structure exists and can be proved from the first charging/discharging curve of original lithium titanate and samples after ball-milling(Figure 4d), it could conclude that monophasefield has increased after ball-milling. According to Park's and Zhou's opinion that monophasefield attributes to the surface decoration of lithium titnate crystal, it is definitely the increasing monophasefield that improves its electrochemical performance.
