Above the crossover strain rate,the G′ values are greater than G″ . And with the increase of ω , tan δ decreased. From the G_c at the crossover point, the order of polydispersity of three cellulose canbe concluded as following: 2#>3#>4#.
The results of experiment showed that DS superalloy DZ125 exhibited a crossover point of the in-phase and out-of-phase mechanical strain-life curves, - 135° phase angle lives were longer than that of in-phase and out-of-phase thermomechanical fatigue.
First of all,according to the principle of invariant light speed and physical relativity,deduction was conducted for spherical wave front equation and linear transformation formula for one event in two inertial systems containing all coincides. Then,according to the spherical equation and the coordinate of the crossover point of the two spheres and the coordinate axis,coefficient of the linear transformation formula is determined,and the Lorentz transformation is obtained.
Samples under any processing conditions, G′ values were higher than G″ values, there was no crossover point for G′ and G″ within a magnitude, η* values decreased in across several magnitudes as frequency increased, a weak gel was exhibited in the system.
For the catalog obtained by aggregating 14 subduction zones of the Circum-Pacific Seismic Belt, our estimate of the crossover point is log(c0)=28.14 ± 0.40 (c0 in dyne-cm), corresponding to a crossover magnitude mW=8.1 ± 0.3.
This paper describes experiments in which damage and silicon dose were independently varied through the crossover point.
This qualitative difference implies that there must be a crossover point between the low- and high-dose regimes in the effect of damage and defect formation on dopant activation.
Attitudes toward the degree of ambiguity also reverse at the crossover point.
Estimates of the crossover point from ambiguity aversion (fear) to ambiguity seeking (hope) place this value between 0.3 and 0.7 for the risk per decade lotteries considered, with empirical estimates indicating a crossover mean risk of about 0.5.
