The invention discloses a thrombelastogram calibration method, device, system and equipment and a storage medium, and the method comprises the steps: generating an initial thrombelastogram in a process that a blood sample rotates along with a container, through a mechanical torsion signal which drives a suspension wire to move in and after a process that the blood sample forms a blood clot, and collecting the initial thrombelastogram through a mechanical sensor; the method comprises the following steps: generating a light intensity time change chart through near-infrared light signals collected by a spectrograph, and extracting an attenuation rising rate representing a blood sample coagulation rate, an attenuation value representing blood sample coagulation intensity and an attenuation recovery rate representing fibrinolysis after blood sample coagulation, so as to calibrate an initial thromboelastogram and obtain a calibrated thromboelastogram. Therefore, on the basis of the thrombelastogram measured on the basis of the mechanics principle, the attenuation signal measured by the near-infrared optical principle is utilized to calibrate the thrombelastogram, the influence of non-coagulation factor interference on only mechanical signals is reduced, and the accuracy and the reliability of generating the thrombelastogram are improved.

The invention relates to the field of coal-fired flue gas treatment, and discloses a method for removing SO3 in coal-fired flue gas through charge coagulation, which comprises the following steps: S1, a pre-charging step: enabling SO3 aerosol to carry first polar charges; s2, a generation and injection step: atomizing the alkaline solution into alkaline microdroplets carrying second polar charges; s3, coagulation: driving the two kinds of particles to move relatively by utilizing the traveling wave electric field; s4, acquiring a real-time feedback signal reflecting the coagulation efficiency; and S5, dynamically adjusting the operation parameters based on the feedback signal. According to the invention, electric field forces with opposite directions are applied to SO3 aerosol and alkaline microdroplets carrying charges with opposite polarities through a traveling wave electric field to drive the two kinds of particles to generate relative motion, and the particle coagulation is converted from a passive process depending on slow Brown diffusion into a capture process dominated by an external electric field, so that the particle coagulation efficiency is improved. Furthermore, the collision frequency and the coagulation rate among the submicron particles are improved.
