field frequency การใช้

• It was specified to have a 50 Hz field frequency.
• From the results, they were able to conclude that the electric field frequency, rather than an internal frequency measure, was used as a reference.
• The sensor coils are connected via thin ( 12-microm ) wires to a set of nine lock-in amplifiers, each locking to one of the three field frequencies.
• Dielectric heating of liquid water is also temperature-dependent : At 0 癈, dielectric loss is greatest at a field frequency of about 10 GHz, and for higher water temperatures at higher field frequencies.
• Dielectric heating of liquid water is also temperature-dependent : At 0 癈, dielectric loss is greatest at a field frequency of about 10 GHz, and for higher water temperatures at higher field frequencies.
• Besides preservation of the European electronic industry, there was also a need to produce a standard that would be compliant with the 50 Hz field frequency systems ( used by a large majority of countries in the world ).
• When the rotating wave approximation ( RWA ) is invoked, the resonance between the driving field and a pseudospin occurs when the field frequency \ omega is identical to the spin's transition frequency \ omega _ 0.
• The process of Trojan wave packet formation by the adiabatic-rapid passage depends in ultra-sensitive way on the reduced electron and nucleus mass which with the same field frequency further leads to excitation of Trojan or anti-Trojan wavepacket depending on the kind of the isotope.
• European standard definition broadcasts use 720?76i / 25, meaning 25 720 pixels wide and 576 pixels high interlaced frames : odd lines ( 1, 3, 5 . . . ) are grouped to build the odd field, which is transmitted first, then it is followed by the even field containing lines 2, 4, 6 . . . Thus, there are two fields in a frame, resulting in a field frequency of 25 ?2 = 50 Hz.
