strain pattern
1.By systematic monitoring the stress-strain pattern of bottom drifts using JXH-2 concretestrain-wire gage, the stress-strain relation in slusher drifts was revealed, and it was foundthat there are two most dangerous periods of drift support during block caving mining,whichprovides a practical basis for ground control and monitoring in a block caving system.
4.This paper has made analysis in detail, on two principal difficulties in the fabrication of a Force-Measuring Bearing (FMB) - the determination of the optimum depth of groove for setting strain gauge and of optimum pattern to distributing it, and presented Finite Element Methode and Photoelastic Method to solve strategy.
8.An updating detection approach to fuzzy-pattern identification based on strain mode is also presented to locate the specific bolted looseness damage by the reduplicative detection of distance nest degree and proportion nest degree.
9.Methods Virulence genes and some phenotypes, including stx, hly, EPEC and EHEC general eaeA, EHEC specific eaeA gene with PCR, and ETEC ST and LT with ELISA, and adherence ability to HEP 2 cell, and plasmid pattern, were determined in 8 strains of non Shigatoxinogenic E. coli O157 from Hangzhou, EHEC O157∶H7 strain 933 from US and strain 88 2364 from Jiangsu province in China. Results In 8 strains of non Shigatoxinogenic E.
