light metal element造句

( 3 ) the free - standing porous silicon films with continuous porous structure were prepared on single crystal silicon wafer by the method of anodic oxidation and electrochemical etching - electropolishing , and firstly used as the anode materials for lithium ion secondary batteries . the capacities of lithium ions storage and the process of charge and discharge of this nano - silicon anode materials as well as the influence of the structure of ps on behavior of storing lithium ions were inspected at length . on the other hand , through the process of charge and discharge in cells , the lithium of light metal element could be electrochemically doped into ps at different doping levels
胡劲松河北师死大学硕士学位论文（ 3 ）利用阳极氧化法在单晶硅基底上制备了多孔硅自支撑膜，并首次将这种具有连续多孔结构的硅材料用作了理离子电池的阳极材料，考察了这种纳米级硅阳极的储钾性能和充放电过程，分析了材料结构对其储理行为的影响；另一方面，利用这种电池充放电过程在多孔硅中电化学引入了不同点缀程度的轻金属钾元素，考察了钾点缀对多孔硅自身结构，及至性质所带来的影响，提供了一种通过电化学方法插入埋离子从而连续调整多孔硅发光性质的有效方法。
