In this paper by applying the poloidal-toroidal decomposition of a velocity field, Oberbeck-Boussinesq equations are transformed into a new equivalent system.
By using the equivalent model,contact force of ideal trochoid transmission was calculated,and the calculation result agree relatively well with a theoretical one.
This method is a better technique to synthesiz THDB, its inhibitory activity against tyrosinase is better than arbutin or kojic acid, equivalent to phloretin.
Considering the subnormal subgroups,some equivalent conditions for nilpotency of finite groups are given and a sufficient condition for nilpotency of finite groups is obtained.
The deductive method of atomic spectral terms for equivalent and nonequivalent configurations is the key part of the study of quantum chemistry, structural chemistry and atomic physics.
The temperature of hot strip at finishing rolling interstand has been calculated by established short-cut calculation model and defined concept of equivalent interstand distance and fundamental value.
This paper makes a meshing analysis about the spiroid gearing. Using the method of equivalent worm gearing, the assembly condition of Archimedes spiroid gears has been obtained.
In this paper, we proved that the definition of a semilattice as a universal algebra and the definition of a semilattice as a partial ordered set are equivalent.
Orwell feared we would become a captive culture.Huxley feared we would become a trivial culture, preoccupied with some equivalent of the feelies, the orgy porgy, and the centrifugal bumblepuppy.
Some birds take the “wingman” approach to scoring a mate, the ornithological equivalent of two guys sallying up to a hot girl in a bar in hopes that one will get lucky.
My friend explains that troublemaking party animals see how many people can stand on the deck of an unfortunate boat and eventually they submerge it -- the canal equivalent of rolling over a car.
