Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction. It demonstrated that allantoic fluid of each passage virus could hemagglutinate chicken red blood cells by treatment with 1% trypsin. The standard positive serum to IBV could inhibited the hemagglutination. The isolates could make respiratory and kidney diseases in chickens.

It was found that electrical field strength and potential around the the sample changed less in the fully insulated chamber than in conducting material phytotron, so it is closer the real condition. Based on the design, the first fully insulated large artificial climate chamber in China, in which temperature , humidity, and atmospheric pressure can be regulated, has been built in our laboratory. The paper developed an insulation parameters automatic test system of high voltage capacitive equipment based on LabVIEW. In the chamber, On-line tanδmeasurements of the capacitive transformer bushings were completed. The effects of environmental factors on tanδwere analyzed, and the curves between the tanδand the environment parameters were acquired. Then, a grey relational model to analyze the effects of main environmental factors on tanδwas built, and the grey relational grade between them was gained in this paper.
