The capacitance coupling mechanism of the testing pulses, which are within the frequency range from 2MHz to 6MHz and that from 7MHz to 12MHz and propagate along the circumference enveloping the head of stator windings, and the variation law of their amplitudes are analyzed.
Experimental results indicate that the phase parameters of GFRP fibres with respect to cutting direction change in the circumferential direction at cycle;
The effects of curvature radius and cutting speed on the top kerf width of circumferential laser cutting of thin seamless steel pipes with a small diameter (outer diameter of pipe D <80mm and wall thickness t =2.5mm) were investigated experimentally .
When the periphery velocity of thrower paddle is less than 13.5m/ s ,the practicle maximum throwing height of grain is only about 1/4, of the theoretical value (don't regard all of the energy loss).
In this study, the finite element method has been applied to calculate the potential distribution and current distribution along circular periphery of the pipe.
During the experiment a series of static stream pressures are measured at 12 tappings in the volute outlet, which are arranged on both sides of 6 places spaced equally on its periphery.
Because the rotational flow of the internal groove reduced the effect of natural convection, the internal wall temperature of internally ribbed tube uniformly distributed along the circumference.
Despite the nonconvexity of the terminal set, by which the circumference serves, it is possible to perform the proof of the unsolvability with the aid of a rather simple mathematical technique on the basis of the Schauder theorem for the fixed point.
In our paper [KR] we began a systematic study of representations of the universal central extension[InlineEquation not available: see fulltext.] of the Lie algebra of differential operators on the circle.
As an application we produce complete hyperbolic 5-manifolds that are nontrivial plane bundles over closed hyperbolic 3-manifolds and conformally flat 4-manifolds that are nontrivial circle bundles over closed hyperbolic 3-manifolds.
A simple parametrization is given for the set of positive measures with finite support on the circle group T that are solutions of the truncated trigonometric moment problem:
These results may all be viewed as generalizations of the fast Fourier transform algorithms on the circle, and of recent results about Fourier transforms on finite groups.
This is done by proving that a well-known method, the construction of a Perron Tree, can be applied to a larger collection of subsets of the unit circle than was earlier known.
A class of steady similarity solutions of the equations for viscous vortex cores which correspond to external inviscid similarity solutions with a power-law variation of the circumferential velocityv-r-m near the rotation axis is considered.
Circumferential and radial components of the yolk cell surface movements were measured in the loach embryos at the late blastula stage within 40-50 min after puncture or indentation by an obliquely directed glass rod.
In the vicinity of puncture, the yolk cell surface at first contracted in both circumferential and radial directions and then widened, but did not reach the initial values.
The multipotent cells of the retinal ciliary-terminal zone and cells of the pigment epithelium in the eye periphery provide for the growth of amphibian and fish eyes during the entire life of these animals.
A mechanism of quenching is proposed, which involves the formation of a charge-transfer complex including an excited tacrine molecule and indole of the tryptophan residue from the periphery of cholinesterase active site.
Keratinocyte spreading increased in the attached aggregates, where densely packed and well spread cells could be recognized in the aggregate center and periphery, respectively.
It is established that the chains with one associating terminal group form tree-like coral-shaped aggregates; associating groups form the skeleton with a large number of branches at the periphery.
