A testing system utilizing grating is set up to test this new motor, and the theoretical movement principle for the motor is proved by experiments. The pulse waveforms are applied to drive the motor to move in steps. The motor has a displacement resolution of 10 nm and a maximum velocity of 0.6 mm/s. It can drive a 200 g slider whose range is 20 mm. A one-dimensional precision positioning platform is fabricated by using the new hybrid piezoelectric motor. The prototype is made up of two servomotors and two piezoelectric motors, which are controlled automatically by a computer. The positioning range of the platform is 10 cm.展开更多

Art decorative design reflects the characteristics of the environment, history and culture of a city and a state of the spirit of the times. Modem art deco design should not only have its own style, but also be more perfectly reflect the cultural connotation of specific urban environment, and to create a pleasant living environment for human being. Aesthetic concepts of decorating space environment are inseparable from the people＇s view of decoration. Analyzing from the sensory effects and psychological effects of decorative environment, the paper points out the way for environmental decoration development, and provide ideas for future creative decoration.展开更多
