    摘要： The present invention provides a driving method of a linear motor, comprising: S1: providing a motor having a vibrator; S2: inputting a first driving signal to the vibrator to drive the vibrator to vibrate so as to generate a displacement; S3: monitoring the current displacement of the vibrator; S4: determining whether the current displacement of the vibrator is greater than or equal to a preset maximum displacement of the vibrator; S5: if the current displacement of the vibrator is greater than or equal to the preset maximum displacement of the vibrator, providing a second driving signal having a preset duration to the vibrator, so as to provide a electromagnetic force having a direction opposite to the direction of the current displacement; S6: providing the first driving signal to the vibrator again so as to drive the vibrator to continuingly vibrate.

    摘要： An apparatus and method for measuring molecular diffusivity in porous powders or minerals, e.g., the microporous synthetic minerals used for gas separation and chemical catalysis, were invented that allows a varying pressure in the gas around the powder during the measurement. This obviates the need for the pressure to be constant and the attendant complicated component parts. A mass balance model equation of the sample cell with the diffusivity as an adjustable parameter is used to deduce the sample cell pressure change versus time (uptake curve) until the equilibration of gas diffusion into the powder. A numerical analysis method is used to solve the mathematical model to compute a simulated uptake curve. Curve fitting of the simulated and measured uptake curves is used to optimize the diffusivity parameter, which gives the measured diffusivity. The apparatus and method are simple, easy to use, and automation is also simple.

    摘要： A time control system for multiple motors is provided in the present disclosure. The time control system includes an event generating module for generating event information corresponding to an event, a control module for analyzing the event information, a signal selecting module for selecting vibrating information according to the event information, a motor module comprising multiple motors, and a driving module for driving the multiple motors in the motor module to vibrate. The control module is further configured for determining whether the vibrating information need to be delayed, and the time control system further includes a delay module for delaying the vibrating information for a time period before sending the vibrating information to the driving module to delay driving the motor module.
