Abstract:
Objective:To provide a criterion for determining whether a mouse's health by analyzing the time-frequency local characteristics of nonlinear and unsteady mice blood spectrum signal.Methods: Collect the blood spectrum signal of the normal and liver damage mice by infrared spectrum method, then study the mice blood spectrum signal by Hilbert - huang transform method.Results: Initially formed criterion on judge whether there is hepatic injury in mice signal.Conclusion: Analysis method based on HHT in mice blood signal spectrum analysis can accurately determine the health of the mice and it provides a new method of analysis for noninvasive blood tests.
