Disclosed is a method for qualitative and quantitative determination of key substances in mixture based on terahertz spectrum. Terahertz spectrum of a reference mixture is trained through an SVR algorithm, and predicting parameters of key substances in the mixture to be determined after a model is generated. According to the method, an initial pure spectrum corresponding to each composition in the mixture does not need to be separately determined, no limitation on the number of samples contained in the mixture, and no limitation on frequency range to be determined, and the proportion requirement of the mixture in the early test stage is not limited, and the SVR model does not need to be re-trained after a database is formed in the later stage, and the result can be obtained immediately after the spectrum of item to be determined is introduced into the algorithm model.

A magnetic alignment system is disclosed, including a magnet array (), a motor rotor (), a fixed tooling () and a force sensor (). The motor rotor () is disposed over the magnet array () and is connected via the force sensor () to the fixed tooling () that is positionally fixed relative to the magnet array (). By varying an angle of a three-phase current supplied to a specific one of three-phase coil assemblies in the motor rotor () within an angular range for magnetic alignment and measuring a force generated by the specific one of three-phase coil assemblies using the force sensor (), an angle of magnetic alignment for the specific one of three-phase coil assemblies is determinable based on the angle of three-phase current that causes the specific one of three-phase coil assemblies to generate a maximum force.
