1. 详细描述样品有着怎样的形貌,由哪些微观结构组成,是什么原因造成的。
实例一:SEM imaging shows that the as-deposited films consist of platelets roughly 100 nm in diameters that tend to be vertically oriented and randomly distributed on the electrode surface. This morphology is consistent with that typically observed for layered double hydroxides or oxyhydroxides adopting a brucite-like structure with octahedrally coordinated metal cations hexagonally packed insheets that are separated by water and charge-balancing ions.

变型:The __ had typical diameters of ~ nm and (thin, wide) shells that were ~ _ nm thick. SEM images recorded at high magnification clearly show the (perfect) __ shape of the __, with uniform shapes and flat surfaces. (Kong, X. et .al. Science, 2004, 303, 1348-1351)
实例二:High-magnification SEM images show that the rods that compose these tubular structures are highly ordered, with the gold ends on the exterior of the structure and the polymerends all pointing toward the interior of the tubes. Rods with a 3:2 gold/polymer ratio also yield tubular structures but with ~ 29 μm diameters.

实例三:The scanning electron microscopy (SEM) images of both ZnO films also showed essentially the same smooth surface morphology composing of closely packed particles with a particle size of 30?50 nm, indicating that each particle was a ZnO single crystal since this particle size was similar to the one calculated from the XRD results.
(Ref. Ong, B. et al. J.Am. Chem. Soc., 2007, 129, 2750–2751)
