thecondensation and crystallization of the author's over 50 years
ofscientific research and teaching experience. In order to helpreaders
to understand crystallography theory, to establish vividthree
dimensional concepts of symmetry operations, simple geometryconcepts and
methods are employed in the analysis and derivation ofthe symmetry
principles and diffraction theory in this book. Thisbook is divided into
three sections: fundamental principle ofgeometric crystallography,
symmetry principle in the microscopicspace and fundamental principles of
crystal X-ray diffraction.InSection I and Section II, with the
application of consistencyprinciple between the distribution of general
symmetry equivalentpoints and the spatial symmetry,the macroscopic and
microscopicsymmetry and their combinations are intensively analyzed
anddiscussed. The 32 point groups and 230 microscopic
symmetrycombinations are systematically derived as well. In Section
III,based on the relation between crystal lattice and its
reciprocallattice, the mathematical model of reciprocal lattice, Ewald
sphereand their relations are adopted in the elucidation of Laue
Equationand Bragg Reflection Equation. Several important single
crystaldiffraction measurement methods, instruments and their
applicationsare also illustrated. In addition, through the principles
ofsystematic absence of reciprocal lattice caused by
microscopictranslations, the systematic absence principle of diffraction
isillustrated. The 120 diffraction groups are derived as well....
