( 3 )变生态矿物拉曼光谱的强度很弱、谱线宽而弥散，而退火晶态矿物的拉曼谱峰强而尖锐。
A new synthetic method , like sol impregnation method , was used to synthesis licoxni1 - xo2 compounds . using this method , reactants ni1 - xcox ( oh ) 2 and liohh2o can be maximizing mixed through the organic reagent impregnating and the original particle pattern and reactivity of the precursor ni1 - xcox ( oh ) 2 can be hold . the results indicate that the method has avoids the shortage brought by classical method
用xrd 、 sem等分析手段，从理论上分析了前驱体ni ( oh ) _ 2的结构特征，发现峰形尖锐，晶型完整，晶体有序性好的ni ( oh ) _ 2活性低；而晶体有序性差，结构不完整，有较多的品格缺陷，且( h01 )型谱线宽化严重的前驱体ni ( oh ) _ 2活性高。
