The award for the most uniform field
of stock went to George Farr and Mark Richardson, from Pallinsburn, for "very level Texel x home bred gimmers".
The breakdown properties of [SF.sub.6] gas mixtures in uniform field
under impulse and direct voltage have been studied in earlier researches [7-9], but the examination of the characteristics in nonuniform fields is open to research.
When the pattern was studied, the atoms - which according to predictions would fly in random directions - actually left in a uniform field
Even when using a much thinner Teflon of 2 cm we are within 15% from the optimum (in the uniform field
In the field of permanent magnet usually two effects, the magnetorheological effect (in uniform field
) and magnetophoretic effect (in nonuniform field), may occur simultaneously.
Since Robusta trees cannot pollinate themselves as Arabica trees can, it is more labor intensive to generate a uniform field
This "wall" is the cosmic microwave background (CMB), which registers to us as a nearly uniform field
, 2.7[degrees] above absolute zero.
"At 300 MHz, the excited dipole has an approximate 3[lambda]/2 electrical length where the maximum of current is located away from the feeding position, exciting a longitudinal two-peak SAR distribution..,..[The] passive shielding plate exhibits a half-wavelength eigen-resonance, which yields a transversal two-peak SAR distribution." (6) Distributing the peaks in this way creates four low peaks and a much more uniform field
than in the 25-cm device.
Hence achieving large area of uniform field
is a challenging but critical issue for the high field MRI with large FOV.
[sigma]([Q.sub.E]) is smaller because of the uniform field
within the working volume.
