transition point
1.The temperature of BaB_2O_4 phase transition is 920±10℃,and near the transition point the incubation time is very long.
2.The glass-transition point for EGBAA is very low(-70.8℃), EGBAA has a high thermal stability and a low sensitivity.
3.Because the way the dark energy density varies is dependent on the theoretical model, each theory predicts a different time for the transition point when the expansion of the universe switched from slowdown to speedup.
4.The transition point of CDW is near to 30k accompanying with the superconductiviting phenomenon. By analyzing the XRD patterns and the r-T curve of NbSe_2,the reappearance of the SbSe_2 crystals at low temperature are discused.
5.Niobium nitride (NbN) is a good superconductor, and it has a higher superconducting transition temperature (T c) than pure niobium. Through experiments, we find that the T c transition point of niobium films rises to about 9.6K by using NbN interlayer between OFHC substrate and niobium films. So using this method can improve the superconducting properties and thus the acceleration properties.
6.In viewing of the characteristics of propagation of 3D converted wave, studies are performed on the processing methods of 3D converted waves, such as horizontal component rotation, calculation of 3D transition point, hyperbolic velocity analysis and NMO (normal moveout) correction of 3D converted wave, and non-hyperbolic velocity ratio analysis and NMO correction of 3D converted wave.
7.For metals that experience the gradual elastic-plastic transition, the point of yielding is determined as the initial departure from linearity of the stress-strain curve and this is sometimes called the proportional limit.
8.This paper studied the effects of Sb and Ti system catalyst on the synthesizing process the heat shrinkage film polyester,as well as the effects of comonomers as CHDM,DEG and IPA on the glass transition temperature (T_g),melting point (T_m),crystallizing performance,thermo stability of the heat shrinkage film polyester and the properties of heat shrinkage film.
9.The present model is thermodynamically unstable in the pressure-ionization regime and predicts the existence of a plasmas phase transition occurs between a critical point Tc=15.5 K,Pc=58.3 GPa,and ρc=0.3226 g/cm3.In the high-density phase,complete pressure ionization is reached suddenly. Theoretical results for the critical point of the hypothetical plasma phase transition in hydrogen have been compared with the calculations of the various models.
10.The results demonstrate that the tilted phase affects not only the relative shift and the transition height rather than the turning point, but also affects the truncation parameter region when the focal switch appears.
