2.Insulator-based(electrodeless) dielectrophoresis(iDEP) is an innovative approach which is widely used as biopartical separation in the micro total analysis systems(μTAS). The non-uniform electric field needed for dielectrophoresis(DEP) is produced by microarray insulators in the microchannels according to the new method.
3.The electrophoretic microchip fabricated by MEMS technology is successfully used to finish the electrophoresis process.
4.3 In experiment the common electrical-resistance strain gages is used as receiver to replace the PZT or velocity and acceleration transducer which is frequently used in pipeline NOT.
5.IF electric heating pipes are put into operation firstly,preheat the pipes to the maintenance temperature of media,then open valve.
7.After the cathodic protection measures ie the deep well anode bed plus impressed current were adopted for the underground pipeline network of Eureka unit in the refinery of Yangtz Petrochemical Company, the protection voltage was - 0.852 - -2.0. This reduced the leakage by 63.6% compared with that without the cathodic protection and the pipeline operation life could be extended by 20 to 25 years.
8.This paper introduced the present condition of fuse salt electric tracer heating temperature control in the introduced project "tubedigestion" of China wall aluminium corp. using japanese mitsubishi A2 serial programmable controller to achieve the practice process of molten salt electrcity heat tracing temperature control system,the composition of system and main function.
9.By analyzing in detail these factors , it is concluded that (1)anode allocation is vital important in the CP design, and the current distribution can be improved effectively by adopting flexible anodes for the pipeline with aged coating;
