Mechanical behaviors of soft rocks based on the fractional thermal elastic-plastic theory [PDF]
Soft rocks have complex thermodynamic behaviors and their strength maybe increase or decrease with temperature. In this paper, the soft rocks were considered as heavily over-consolidated clays and their preconsolidation pressure was assumed to be the ...

Study on mechanical properties and damage characteristics of granite under thermal shock based on CT scanning [PDF]
During the exploitation of deep geothermal resources, the thermal fractures of high-temperature rocks are usually induced by the impact of low-temperature fluids to improve the permeability of reservoir rocks.

Pore structure characteristics of middle and low rank coals and their influence on gas desorption characteristics [PDF]
The pore structure of coal is an important factor affecting gas storage and migration. In order to further study the gas desorption characteristics of low and medium metamorphic coals, 6 sets of coal samples from the Fukang mining area were selected for ...

Browning mechanism of indigo juice during processing prevention and control technology [PDF]
Objective: Indigo fruit juice is prone to browning during processing. Methods: A kinetic model was fitted by determining the changes in browning degree, vitamin C (VC) content, and 5-hydroxymethylfurfural (5-HMF) content of indigo fruit juice during the ...

匝道弯桥线型优美、适应性强,广泛应用于城市道路交通建设中。然而,较小的曲率半径也容易引发一些病害事故,例如支座脱空、梁体侧移、预应力筋崩出、甚至梁体倾覆等。为分析匝道弯桥的受力性能,同时找出这些问题产生的主要原因以及作用规律,本文以某实际匝道弯桥作为工程背景,通过建立有限元建模,并施加多种荷载工况进行计算分析,探讨了不同曲率半径和跨径对匝道弯桥基本力学性能的影响。福建省交通运输科技项目 ...

Synthesis, Structure Modulation and Photoluminescence Properties of Silver Coordination Compounds [PDF]
由于具有丰富的结构和多样的性能,近二三十年来配合物是科研的热点领域。实现对配合物结构和性质的控制是晶体工程的重要目标。然而,配合物自组装反应受金属离子、配体、阴离子、溶剂等很多因素的影响。一价银离子具有d10的电子构型,配位几何多变,且可能形成亲银作用,银配合物还可能具有荧光性质。本文研究的是阴离子、羧酸、溶剂调控的银与几种含N配体的配合物。 第二章论述的是阴离子调控的1:1的银-2,4-二氨基-6-[2-(2-甲基-1-咪唑基)乙基]-1,3,5-三嗪(L1)配合物。1,5 ...

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 ...
