The configurational contribution increases with temperature, and the excess Cp and entropy near the solid-liquid transformation temperature are 36.7 and 2.1 J K-1 mo1-1, respectively. The increase is interpreted as indicating the onset of molecular mobility in vitreous ice. The configurational Cp ,...
Powder X-ray diffraction patterns at room temperature for all the samples are shown in Fig. 2a. The results reveal that the PbSe0.5S0.25Te0.25 sample has split diffraction peaks, which come from the multiphase mixture with modulated composition. Upon introducing Na, the split peaks converged into...
It can be observed, that at low temperatures σAC follows the universal power law only in low frequencies and the maximum limit value of frequency in which universal power law can be used increases with increasing temperature. This behavior in high frequency range can be described by nearly ...
[translate] aThe reason is that, with the increase of nucleotide number, the thickness of ssDNA brushes increases, which enhances the conformational entropy 原因是,随着核苷酸数字的增加, ssDNA的厚度掠过增量,提高构象熵[translate]
In the Tropics, the variation of rainfall with sea surface temperature (SST) is highly nonlinear. Rainfall shows no dependence on SST for SST increases fro... I Folkins,C Braun - 《Journal of Climate》 被引量: 3550发表: 2003年 Entropy generation minimization: The new thermodynamics of finite...
摘要: A simple model of spacetime foam, made by N wormholes in a semiclassical approximation, is taken under examination. We show that the Bekenstein-Hawking entropy is here "quantized" in agreement with the heuristic calculation of Bekenstein.关键词:...
Steady natural convection heat transfer in a two dimensional cavity filled with a uniform heat generating, saturated porous medium has been studied. The bo... ZG Du,E Bilgen - 《Heat & Mass Transfer》 被引量: 65发表: 1992年 Effects of temperature-dependent viscosity variation on entropy genera...
Wildfires occurred at varying elevations from 2 to 2030 m, with most above 800 m. Since BIO7 is an indicator of the annual temperature range and lightning occurs mostly in forest areas, leaf type has a decisive role on the ignition of wildfires when lightning occurs (Table 4). Table 4 ...
(4) In general, RI reflects a combination of reward-dependent and reward-independent strategies as well as the sensitivity of choice to value differences (equal to the inverse temperature in the logit function translating value differences to choice probability; see Eq. (28). ...
For this sample, two Gaussian sub-peaks, r11 and r12, can fit the first peak of G(r) very well with a coefficient of determination (R2) better than 0.999 (Supplementary Note 7 and Supplementary Fig. 17). As the temperature increases, the relative changes of the peak positions and peak ...
