, 2004 自然条件下天然气气体水合物的平衡条件对估算气体水合物储量，确定海底天然气水合物的稳定区域，得到气体水合物生成、分解速率非常重要。针对整块气体水合物相平衡条件的实验测定和预测模型无法准确确定自然条件下气体水合物的平衡条件，目前一些学者对多孔介质中气体水合物的平衡条件进行了实验测定工作，并先后建立了多个理论预测模型。文中详述了多孔介质中气体水合物相平衡条件的实验测定和理论预测模型，讨论了实验测定和理论预测模型尚待完善和改进的地方 ...

, 2007 分别利用两种热力学方法（基于逸度相等的方法与基于活度相等的方法）预测了不同多孔介质中气体水合物的平衡分解条件，对于非水合物相，逸度方法采用Trebble—Bishnoi（TB）方程，而活度方法则使用Soave—Redlich—Kwong（SRK）方程，对于水合物相，两种方法都利用了van der Waals—Platteeuw模型结合Llamedo等关于毛细管力作用模型来模拟．两种方法的预测结果与实验结果吻合 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Understanding learners’ English speaking self‐efficacy is essential for promoting effective oral communication in EFL contexts. However, variable‐centered research on English speaking self‐efficacy often overlooks heterogeneity among learners.

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Arranging functional units into a specific organization is a practical structural strategy for achieving fabulous performance, known as the functional unit and organization (FUO) paradigm. This paradigm offers a concise shortcut to establishing structure–performance relationships.

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Functional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
