摘      要:Scientists exploring the micro-world of matter want to know the structure of matter inthe molecular or atomic ***,the conventional X-ray diffraction and selected areaelectron diffraction (100 KeV incident electron energy) can provide,in the best case,the mean structure information from a sample area equal to or larger than 1 μm in diame-ter;in these experiments,the signals caused by an individual dislocation,a few of atomicplane faults or a single boundary are almost invisible,because they are really too
