This paper analyzed ⋀ item in the gravitational field equation of Einstein from the perspective of the universe symmetry, pointed out the ⋀ term exists is the ether existence. In the transform of Euclid, allows the physical information superluminal. Ether is light and superluminal information carrier.
This paper introduced a design of liquid automatic filling system, and shed light on the working principle and hardware structure of the system. The paper focused on analyzing principle and method of how to use temperature measurement circuit and the ultrasonic technology to detect flowing liquid. And it discussed what caused the mistakes which occurred in Packaging film transmission and Ultrasonic...
The formula of distribution coefficient about outlet circulation in the radial direction was derived by the theoretical analysis of the relationship between theoretical head of axial-flow pump with circulation of impeller. The axial-flow model pump with specific speed of 700 was designed with method of variable circulation, employed distribution coefficient according to the derived formula. The hydraulic...
Segregation in the Hot-Mixed Asphalt (HMA) causes inferior homogeneity of pavement structure which is a key contributor to the early pavement damage. This paper, by statistic principles, analyzes the contributive factors to the segregation, indicates the major factors and guides the controls in actual project, thus to reduce the unevenness of the pavement and improve the quality and durability of...
In this paper, the mechanical construction, thermal regulator design and temperature measurement system of a local area were set up for large-scale linear measurement. Numerical analysis based on temperature correlated characteristic is discussed to obtain optimal observation points for the measurements. The horizontal temperature distribution of the measured area is compared with the measurement...
Ultra-precision flexure-hinge guided micro-feed system driven by piezoelectric actuator was applied in many fields in which precise motion was needed. Temperature effects on positioning accuracy of system are analyzed. The temperature measurement and control system are described for the compensation of temperature errors on micro-feed stage and interferometer measurement. The temperature control system...
