查询词典 quantitatively

For the aged aluminum alloys which generally contain disc/plate-shaped or rod/needle-shaped precipitates, a model has been established, from the viewpoints of thermodynamics, kinetics and strengthening theory, to relate quantitatively the yield strength to the size, volume fraction and aspect ratio of precipitates which all were analytical associated with the chemical compositions of alloys, aging temperature and aging time. This model has been experimentally proved to well predict the variation of yield strength with the evolution of disc/plate-shaped or rod/needle-shaped precipitates for present Al-4. 62wt% Cu-0.65wt% Mg alloy aged at 513K and Al-1. 12wt% Mg0.57wt% Si alloy aged at 463K, respectively, and the yield strengths simulated by this model were also found to be in well agreement with previously measured values for a series of aged Al-Cu binary alloys, AA6061 and Al-Zn-Mg alloys.

Five expressed genes contributed to the flowering process and embryonic development such as prolamine, gene for allergenic protein, chalcone synthase, putative peptide methionine sulfoxide reductase and acyl carrier protein Ⅱ gene were chosen to hybridize with a 1510-RNA-blot (time-point phenotypes) array. The 1510 RNA blots were prepared into an RNA array for the purpose of conferring and validating global transcriptional profiles on booting, flowering and filling quantitatively and qualitatively at a statistic level. The results verified: Prolamine and allergenic protein were high-expressed in filling grains after being regulated by development, Chalcone synthase and methionine sulfoxide reductase were high-expressed in the leavies induced by light, in the root stressed for nitrogen deficiency.
