Reason illustrates.
Specifically, as it is shown on figure 3, the impedance R of LL=jwL (w is angular frequency, and j is imaginary part), the impedance R of CC=1/jwC,
Therefore the parallel impedance of L and C is: ZR=(RL+RC)/(RL*RC)=jwL+1/jwC, jw are in a certain frequency (such as frequency
The heating frequency that generator 20 provides) under, for fixing data, jw is equivalent to R, therefore
ZR=R*L+1/ (R*C)=(R*R*L*C+1)/(R*C), fixes under frequency one, and real part C is fixing constant, imaginary part R
A constant it is defined as because frequency fixes.Constant at fixed coil plate 2, fixing pan 1 apart from LC coil distance H not
On the premise of change, then ZR only has L change along with pan 1 material, therefore the relation (f of ZR=f*L can be set up
It is a fixed coefficient).Because conductivityσ's difference of the metal of unlike material is relatively big (such as: silver: 63.01*10^6,
Copper: 59.6*10^6, gold: 45.2*10^6, aluminum: 37.8*10^6), and electrical conductivity directly affects high-frequency inductor L,
Therefore the conductivityσ of different metal and the relation of impedance Z R can be set up: ZR=f* σ.
Further, due to the power W=U*U/ (ZR) when frequency generator 20 works, wherein, U is to fix constant (this
In U refer to the integral voltage under a pumping signal), therefore the relation of power W and conductivityσ can be set up:
W=U*U/ (f* σ).Such that it is able to the power W of the ongoing frequency generator 20 by detecting determines current pan 1
Conductivityσ, and then the material of pan 1 is determined according to conductivityσ.
