By contrasting the dimension and appearance of fe of different precursors , verified it is true that the dimension and appearance of precursor affect these facets of fe . modern measures , for instance xrd , tem , sem , laser and infrared technique etc . are used to research the technique indexes of sfp of fe , such as crystalline , dimensions and its distribution , shape and appearance , assemble status and its oxygen content 对所制备的超微fe粉，采用x射线衍射法（ xrd ） 、透射电镜法（ tem ） 、扫描电镜法（ sem ） 、激光衍射粒度分布测定法以及红外测氧法等现代分析测试手段，详细考察了超微fe粉的晶态、尺寸、粒度分布、形貌与团聚状态、氧含量等多项技术指标。
We also investigated the effect of c on the samples formed by ion implantation of mn and c . we studied the samples " crystal structure and surface appearance by x - ray diffraction and afm , experimental results revealed that with increasing the annealing temperature , the crystal lattice reformed and defect in the surface reduced gradually 还进行了mn ~ + 、 c双离子注入，研究了c对样品性质的影响。利用x -射线衍射法和原子力显微镜对样品的晶体结构和表面形貌进行了研究。发现随着退火温度的升高，样品的晶格质量得以恢复；注入表面形成的晶格缺陷逐渐减少。
Application of modern analytical technology in quality control of traditional chinese medicine ( tcm ) are introduced in this paper , including chromatographic techniques , spectral techniques , nuclear magnetic resonance ( nmr ) , mass spectrometry ( ms , gc - ms , lc - ms , ce - ms , icp - ms ) , dna fingerprint techniques , x - ray diffraction techniques 摘要介绍色谱法、光谱法、核磁共振波谱、质谱及其联用技术、 dna分子诊断技术、 x射线衍射法等几种现代分析方法在中药质量控制中的应用。
Powders properties of different phases such as the granularity , the shape and the component have been analyzed by the methods of sieving , gravity sedimentation , spectrophotometry , scan electronic microscope ( sem ) , transmission electronic microscope ( tem ) and x - ray diffraction ( xrd ) . the results show that technic of ball milling and parameters of heat treatments are important influencing factors to properties of cu - zn powders 采用筛分法、重力沉降法、分光光度法、扫描电镜法、透射电镜法和x射线衍射法对不同阶段的铜锌粉末的粒度、形貌、成分等性质进行了分析，结果表明：球磨工艺及热处理参数对铜锌粉的性能有重要影响。
