Abstract: Disclosed is a method for predicting surface quality of a burnishing workpiece. The method includes the steps: using vibration sensors and signal acquisition instrument to acquire vibration signals generated on a surface of the burnishing workpiece during machining, evaluating the surface quality of the burnishing workpiece based on a coupling coordination degree model, processing signals by using an ensemble empirical mode decomposition method, identifying power spectral density, kurtosis and form factor as signal characteristics, identifying a support vector machine as a decision-making model, optimizing penalty parameters and kernel function parameters by using the Bayesian optimization method, and establishing the relationship between the signal characteristics and the surface quality.

Abstract: The present invention falls within the field of medical technology, and in particular relates to the use of a compound as shown in formula (I). In particular, the present invention relates to the use of the compound as shown in formula (I) in the preparation of a pharmaceutical composition for preventing and/or treating a nerve injury, or relieving a nerve injury-associated symptom, and further relates to the use thereof in the preparation of a healthcare product for protecting an injured nerve and/or improving motor function. After a nerve injury has occurred, the compound can reduce the production of pro-inflammatory cytokine, decrease the level of apoptosis, promote the survival of neuron, inhibit the formation of glial scar, and has a significant effect in promoting the recovery of motor function.
