This paper mainly discusses the importance of intellectual fire fighting system,analyses the problems in design,construction,debugging and management,and proposes the corresponding measures.

Fire-fighting system is an important part of oil depot and fire-fighting pump station design and its equipments are the key of fire-fighting system design.

Combined with engineering situations of Jinmao international building design methods of its water supply system,drainage system and storm-water system are introduced as well as design contents related to fire-fighting in order to make the design water supply,drainage and fire-fighting systems to meet codes requirements.

The crystallographic problems of two-dimensional crystal,such as the matrix expression, the symmetry and the systematic absence law of the crystal's X-ray diffraction, are studied.

In this paper the matrix expressions of equivalent points of microcosmic symmetrygroups of crystal unit spaces and their corresponding reciprocal spaces are applied in the dis-cussion of the systematic absence law of the crystal s X-ray diffraction.
