Consumption is in accordance to amount making the surface just be covered , normally about 15 m2 / l and varies with surface condition
涂布量以表面刚好被饱和为准，随喷涂表面孔隙情况不同而异，大约在15米2 /升左右。
In chapter two , we fabricated r - ni - fe / al2o3 nanocomposites successfully by using ball - milling mixing method plus hot - pressing process . meanwhile , their microstructures are characterized by x - ray diffraction ( xrd ) analyser , transmission electron microscopy ( tem ) , field emission scanning electron microscopy ( fe - sem ) and brunauer - emmett - teller ( bet ) . the results indicate that ni - fe particles are homogenously dispersed in the matrix in the composites
在第二章中，我们采用高能球磨混合方法加上热压烧结工艺，成功制备了ni - 20fe al _ 2o _ 3纳米复合材料，并通过x射线衍射仪( xrd ) 、透射电镜( tem ) 、场发射扫描电镜( fe - sem ) 、比表面孔隙仪( bet )对该复合材料的微结构进行了表征。
