Wire behaves plastically in its elastic range. Without considering the wire plastic deformation, the calculation results of wire stress in overload condition will be conservative. So this paper established the state equation of stress changes based on wire strain curves when the wire is ice overloaded and the produced stress exceeds the limit. Considering the wire strain curves, a new calculating...
The excess using of chemical fertilizer will be disadvantage to keep the ecological balance and protect environment. Because of long effective, non-pollution, etc, microorganism fertilizer can make up the disadvantages of chemical fertilizer. The key problem of exploitation and using microorganism fertilizer is finds the high effective function strains. Potassium bacterium was a kind of important...
Filamentous fungal strains were isolated from the leaves and fruits of Camellia oleifera with the anthracnose disease. The pathogenecity was tested following Koch's postulates. Our analyses identified that all 18 isolated strains were pathogenic to Camellia oleifera. The molecular analysis of the internal transcribed spacer regions of the most virulent isolate confirmed that it belonged to Colletotrichum...
Aiming at the testing requirement in special situations, a kind of high overloading piezoresistive acceleration sensor with a beam-island structure, four sides of which are fixed, is designed. This acceleration sensor uses ceramic package and is encapsulated by nitrogen. Adjusting the dynamic speciality by Hopkinson impact equipment, the testing result indicates that the sensitivity and the linearity...
Agaricus bisporus is a delicious, nutritious mushroom with medical function. Cross breeding is limited due to its taxonomic contradiction. We analyzed rDNA ITS sequences of two high quality Agaricus bisporus strains (No.Tb07, As2796). Tb07 strain was selected from foreign mushroom by CSUFT under protection. As2796 strain was a high quality local strain in nature in China. By sequencing the ITS regions...
Considering the high overload application of the pizeoceramic in the self-adapted bullet, a new piezoceramic actuator based on d33 structure is designed. In this paper, aluminum foil substrate and piezoceramic multilayer are introduced. According to the FEA simulation, this structure can afford a high load to 2000 g, which is definitely enough for the bullet application. The fabrication process was...
