unit basis
5.the stable-monetary-unit concept is the accountants basis for ignoring the effect of inflation and making on restatements for the changing value of the money. the most important accounting principles include the accrual principle, the historicl principle, the relization principle, the matching principle, the prudence principle, the objectivity principle, the full-disclosure principle, the consistency principle and the materiality principle.
8.A displacement model of bar with variable rigidity, applicable to the structure entering into elastoplastic level, is presented. It is based on theoretical solution to the stability of bar with constant section. A tangent rigidity matrix of elastoplastic unit is also derived on the basis of virtual work principle.
10.4, Both the block sedimentation and graben sedimentation, two kinds of different sedimentation-structure unit have been divided on the basis of difference in tectonic activity, sedimentation and volcanic activity. Palaeotectonic pattern in Devonian Period of Qinling is composed of interval three graben zones and two blocks.
