Taking diatomite as the main material, using the solid phase sintering process, diatomite-based porous ceramic whose median powder size and specific surface area of powder are 1.28um, 39.25m2/g, mean pore size of sintered body is 157.8nm respectively ...

In the present work, using Tween 80 as dispersant, acryl amide as monomer, biscrylamide as cross linking, MgO (20 mesh particle size) and TiC (50 nanometre particle size) as do pants, mesocarbon micro bead (MCMB) green bodies and sintered bodies which ...

The photo degradation of fipronil in aqueous with xenon lamp as light source was studied, and the effects of NO3-, NO2- and NH4+ on the photo degradation rate of fipronil were systematically investigated. The results showed that direct photolysis of ...

A new type of electromagnetic linear actuator for vehicle active suspension is designed. Combined with the finite element analysis tool, the effect of actuator structure parameters and power parameters on actuator thrust response is studied. Based on ...

The work environment of control unit is not very well for intelligent circuit breaker, such as electromagnetic interference is one important factor. In this paper, hardware and software were applied as anti-Interference measures to ensure the ...

This paper presents an electro-mechanical impedance (EMI) model for damage identification of thin plate structures. Firstly, a damaged thin plate with a pair of piezoceramic (PZT) transducers bonded on the opposite sides is considered. And the pure ...

This paper presents an embedded omni-vision Real-Time Object Recognizing system which involves collecting image and correction, the Freeman Chain Code methods, Field Programmable Gate Array (FPGA), Digital Signal Processor (DSP) and Private Compute (PC)...

This paper introduces a method to design the external electromagnetic interference (EMI) filters for switching power supplies. The thesis expounds theory and calculates the filter insertion loss, then analyses the impact of the source impedance and the ...

The current drum dynamometer cannot test the vehicle’s dynamic braking performance. The equivalent moment of inertia test method was put forward to simulate the vehicle’s the road braking. A variable mass inertia wheel, whose moment of inertia was equal ...

With the increasingly exhausting mineral resources and deteriorating environmental pollution, current steel making process structure must be optimized and new Iron making technology should be developed in China’s iron and steel industry to save energy ...

Microbial fuel cells (MFCs) generate electricity using bacteria to degrade something and produce current, which have gained much attention. Harmful algae blooms(HABs) in lakes and rivers are on the increase all over the world, which becomes a more and ...

According to the present problems of existing office buildings using air source heat pump, countermeasures were brought forward to solve the problems, such as changing part of the present air source heat pumps to water-cooled cold water units, changing ...
