Objective: To analyze (he features of intravenous urography( IVU), differential diagnosis of caliceal diver-ticulum and to summarize the skill of examination.
Axisymmetric elasticity problem of cubic quasicrystal is reduced to a solution of a partial differential equation with higher-order by introducing displacement function.
The types of deposits basically are differential metasomatism in the later magma, pneumatolytic hydrothermal process, pegmatite process, residual deposits and placer deposits.
In this paper,the contents of herbicide bifenox weredeterminated by the differential UV spectrophotometry at 280nm,and the reference solution was that the 40.
Besides, there is also some alternatives, such as an inductance conversion using differential transformer and space curve deformeter, and variable resistance pressure transmitter.
