Magnetic-inductive device provided in an embodiment of the present invention, specific magnetic field control process and principle are as described below, refer to
Fig. 6-Fig. 7,
The preparation method in magnetic field needed for system is using helix tube current system, according to right-hand screw rule, the magnetic of electric current generation
Field direction provides in which can be convenient.Its size can be calculated with following equation:
Above formula is magnetic field calculation formula in energization solenoid, wherein n is coil unit length the number of turns, and I is electrical current,For a constant value 10- 7。
From point A at central point x on energization solenoid axis, as shown in Figure 7:
For coil unit length the number of turns n, it is assumed that the circle number of practical C coiling is m, and the radius of coiling is r, then accordingly
N calculation formula is as follows:
Using the International System of Units, the unit of each parameter is as follows:
Magnetic induction density B tesla
I amperes of current strength
Length unit rice
It should be pointed out that usually, magnetic induction density B, general to use " Gauss " office, transformational relation is: 1 it is special this
Draw=104Gauss.For specific hardware environment, point centered on x can be taken, so that it may obtain in formula (1) magnetic field size B and
The relationship of electrical current I.The I added in real work to loop can be taking human as adjusting, to realize the magnetic induction density B to generation
Size accurate control.
, can be using setup parameter A as temperature coefficient about extension and contraction control of the present invention, applicant passes through long-term practice
With a large amount of experiment discovery: A is a negative value, i.e. the raising (or reduction) of temperature will wipe vibration frequency to the vacuum tightness chamber in Fig. 1
Rate generates the effect for reducing (becoming larger).So devising a temperature control module in invention, temperature is acted on by central processing unit
Module is controlled, to change the intracavitary operating ambient temperature T of entire vacuum tightness.
Meanwhile wiping vibration frequency and can be influenced by the geometric dimension of vacuum tightness chamber, this is placed in chamber with vacuum tightness chamber
Volume size is related, so in the present invention, diameter of the vacuum tightness chamber in chamber can be indicated with setup parameter D, by reality
Issue after examination and approval that existing D value is bigger, and caused frequency displacement is smaller.Therefore, further, a size control module has also been devised, passes through center
Mechanical motor inside processor control, to change the geometric dimension of vacuum tightness chamber.
Frequency displacement is also directly closely related with the coating of bubble, and bubble inner wall coats chemical material, such as polytetrafluoroethylene (PTFE), can keep away
Exempt from the problem of spin-exchange occurs for atom, to reduce frequency displacement.It, can be close using setup parameter C as vacuum in model of the invention
The material coefficient of closed chamber inner wall.It should be understood that due to after entire vacuum sealing space environment is carried out, inside coating
It has been fixed that, i.e. C is a definite value, does not need to be modified in model of the invention.
The above-mentioned A and D value obtained in multiple different system experimentations is all inconsistent to the frequency displacement contribution of system, but they are all
The correlation of linear increase is presented, therefore, the present invention is further introduced into another parameter K in a model, it is for indicating entire
The frequency displacement coefficient of system, then it can be concluded that following formula model:
In formula, Δ ω is resonance frequency variable quantity, and K is frequency displacement coefficient, and A is the temperature coefficient of frequency displacement, and C is vacuum tightness chamber
The material coefficient of inside coating, T are vacuum tightness chamber operating temperature, T0For reference temperature.Magnetic-inductive device sets in the present invention
It is as shown in Figure 8 to count block diagram:
Vacuum tightness chamber is placed in resonant cavity, and resonant cavity provides energy machine for the atomic resonance absorption of vacuum tightness chamber
System, and given resonant frequency signal to foreign frequency measurement module by coupling ring.
Central processing unit enables the operating ambient temperature that temperature control module changes entire resonant cavity；Enabled mechanical motor work moves
Dynamic vacuum tightness chamber moves up and down, to change in the intracorporal volume of resonant cavity；Receive to send pearl from frequency measuring block
Frequency measurement value signal is simultaneously stored in internal storage.
Illustrate the course of work of magnetic-inductive device from a specific embodiment below, for formula (1), the present invention passes through
Central processing unit controls temperature control module and changes vacuum tightness chamber operating ambient temperature value T, such as T1, T2.Pass through centre simultaneously
It manages device and enables mechanical motor work change vacuum tightness chamber in the intracorporal diameter D of resonant cavity, such as D1, D2.It should be noted that
Here T1, T2 should be corresponded with D1, D2 respectively.This moment resonance signal that frequency measuring block obtains measurement simultaneously
Frequency values Δ ω is transferred to central processing unit and stores, in this way for formula (1), by specific T1 and D1 (T2 and D2), and (Δ
ω 1, Δ ω 2) it substitutes into, due to T0It is definite value with C, it is possible to acquire K, A accordingly.
Accurate in order to improve measurement, the present invention obtains K, A according to above-mentioned method duplicate measurements for several times.Its average value is taken to make
For final result.
K in acquisition formula (1) after A value, substitutes into formula (1) in turn, it is known that due to A < 0, it is possible to pass through carefulness
Ground selects the operating ambient temperature T value and D value of corresponding vacuum tightness chamber, makes
In this way, can obtain array (D and T) makes entire vacuum tightness chamber frequency shift amount zero for specific system.
