WebDec 27, 2016 · Thompson-Gibbs公式： 结晶温度与晶片厚度的关系：结晶温度越高，初生晶片越厚；晶片是不平衡的，有增厚倾向。 故：①晶片厚度不同，熔点不同，故产生熔 … WebGibbs–Thomson equation. The Gibbs–Thomson effect, in common physics usage, refers to variations in vapor pressure or chemical potential across a curved surface or interface. The existence of a positive interfacial energy will increase the energy required to form small particles with high curvature, and these particles will exhibit an ...
WebEquilibrium in a two-phase material with flat and spherical surfaces. where Δ G V = ΔG / v m = ( G β − G α) / v m is the free-energy difference between the two phases per unit volume, vm is the molar volume, and r is the radius of the α particle, which is spherical to minimise the surface area. This is called the Gibbs-Thomson equation. 3. WebThe Gibbs-Thomson effect can cause strong depression of the freezing point of liquids dispersed within fine porous materials. Another notable example of the Gibbs-Thomson …

Web焦耳第二定律. 很容易证实，对于由合适的微观假设定义的理想气体，αt = 1，因此在焦耳-汤姆逊膨胀下这种理想气体的温度变化为零。 对于这样一种理想的气体，这个理论结果意味着： 理想气体的固定质量的内部能量仅取决于其温度（而非压力或体积）。
