Jigger is the main equipment in coal processing industry in China, which is developed towards large-scale device. By using the homemade device LTX-35 jigger as
INCONEL725 is a highly corrosion resistant nickel based alloy capable of being age-hardened to high strength levels. The microstructure observations and the pha
CO has been used widely in the production process of colliery as an index gas to predict spontaneous combustion of coal. But in some collieries there are CO gas
To investigate the non-linear hydrodynamics in horizontal gas-liquid bubbly flow, time-series data of local void fraction were obtained using a double sensor pr
The rotor with bending faults that occurrs on the rotating machinery usually vibrates seriously. This paper investigates to apply the active balancing device on
Polymeric polypyrrole-like (PPy-like) nanocrystallines were fast synthesized through oriented plasma polymerization at atmospheric pressure and room temperature
A 3D FEM model for symmetric thin-wall tube neck-spinning is established. The spinning process is simulated by means of ANSYS software, and the dynamic boundary
A synchronous grammar based on the formalism of context-free grammar was developed by generalizing the first component of production that models the source text
