The kinetic controlling equation method of one source many bodies radon chamber radon concentration
Technical field
The present invention relates to a kind of control method of radgas concentration, be specifically related to a kind of method of the radon concentration of one source many bodies radon chamber dynamically being controlled according to the decay and the leakage rule of radon.
Background technology
Radon chamber is as a kind of standard set-up of demarcating the emanometer device in the actinometry field, this just requires it should satisfy certain performance index, accomplish that in a period of time (tens hours to hundreds of hour) can reach a certain expectation concentration value, and keep this steady concentration.But the leakage that the decay naturally of radon and the technological level of radon chamber cause is an outwardness, requires the absolute stability of radon indoor radon concentration not reach, and can only require to keep stable in the scope that certain error allows, i.e. dynamic stability.
In one source many bodies radon chamber, comprise a main radon chamber and a plurality of auxilliary radon chamber, radon is provided for simultaneously a plurality of radon chambers by a radon need.Require algorithm for design, at first guarantee to have stable radon concentration in the main radon chamber, i.e. which kind of situation no matter, main box must at first have the right of additional radon concentration, and radon concentration is fluctuateed up and down around predetermined concentration.During main radon chamber decay and leaking, the radon that radon need is produced is stored in each auxilliary radon chamber again, and keeps each auxilliary radon chamber in a certain constant radon concentration.
Summary of the invention
The objective of the invention is to adopt flow gas radon indoor radon concentration kinetic controlling equation method, thereby comparatively accurately control the kinetic controlling equation method that source many bodies radon indoor radon concentration provides a kind of source many bodies radon chamber radon concentration.
The object of the present invention is achieved like this: establishing and mending radon is 0 constantly the zero hour, and the radon activity in the radon chamber isQ0, constantly to targett, the radon activity in the radon chamberQtFor:
