Jin‐Mu‐Gan‐Mao tablet is a well‐known traditional Chinese medicinal preparation, which has been used to treat the common cold in China. In this study, a systematic method was established for the qualitative and quantitative analysis of the major constituents in Jin‐Mu‐Gan‐Mao tablet. First, a method of high‐performance liquid chromatography with diode‐array detection and quadrupole time‐of‐flight...
A remarkable preservation of sensorimotor function is observed in patients with refractory epilepsy who were treated by hemispherectomy. Cortical regions in the remaining hemisphere or contralateral subcortical region contribute to the residual sensorimotor function. Somatosensory evoked field (SEF) is used to investigate the residual sensory function in hemispherectomized patients. The SEFs are usually...
This paper implements the double-loop control system of Three-level PWM Rectifier based on the mathematical model. This system achieves the same-phase between current on line side and input voltage by means of electric current loop and make the output voltage follows the given voltage by means of electric voltage loop. Finally, the experimental results the feasibility of the controller, which can...
Based on the shortage of the current permanent magnet synchronous motor rotor position detecting method, using an incremental encoder without detecting the UVW's position, a method of the initial position of permanent magnet synchronous motor rotor was introduced in this paper. Through the motor inflict any stator current vector, according to the motor turning, changing the direction of current vector...
