Study on pressure relief and permeability enhancement effect of cutting coal seam with diamond-bead wire saw [PDF]
In order to explore the pressure relief and permeability enhancement effect around coal seam slot cut by diamond-bead wire saw, firstly, the mechanical model of a doubly clamped roof beam based on the stress of the slot roof was established to analyze ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT High‐entropy alloys (HEAs) have emerged as a transformative class of materials distinguished by their complex chemical compositions, unique microstructures, and remarkable mechanical and functional properties. Traditionally, the discovery and optimization of HEAs have relied on conventional methods, including trial‐and‐error experimentation ...

Shuitu Baochi Xuebao, 2018 坡面水流的输沙能力是影响土壤侵蚀过程的重要参数之一，加强坡面集中水流输沙能力的研究有助于深入理解集中流发生机理，并为防治集中流侵蚀发生提供科学依据。采用室内集中流放水冲刷试验，以黄土高原典型黄绵土为研究对象，研究了集中流输沙能力与放水流量和坡度以及与单宽流量和坡度之间的关系，同时对集中流水力参数和输沙能力的相应关系进行了研究。结果表明:集中流输沙能力随着坡度和放水流量的增加而增加。多元统计分析建立输沙能力与坡度和放水流量之间的幂函数关系发现坡度指标对输沙能力相对放水流量影响更大，而在坡度和单宽流量作用下，

Feedback mechanism of front abutment stress on filling rate of backfilling body in coal burst mine [PDF]
High stress is the main reason for high frequency of rock burst in deep coal mines. Backfilling mining serves as an effective method to control roof strata movement, alleviate the degree of stress concentration, and reduce the failure of surrounding rock

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

New Phytologist, Volume 249, Issue 2, Page 764-776, January 2026.Summary Fine roots are critical for soil resource uptake, yet how declining plant diversity alters fine root biomass (RB) and traits remains unclear. We tested how plant functional trait dissimilarity in shade tolerance, drought tolerance, growth rate, and nitrogen‐fixation ability drives variation in root attributes.

Gaoya dianqi, 2021 电力设备绝缘裂化常常伴随着局部放电,如何提高电力变压器局部放电的检测精度对于研究其绝缘状态具有重要意义。集合经验模态分解法(ensemble empirical mode decomposition,EEMD)在局部放电的去噪过程中得到良好的应用,然而对于如何准确的选取EEMD分解过程中的固有模式函数(intrinsic modefunctions,IMFs),还原局部放电真实信号是关键。针对这一问题,文中提出一种基于相关系数的EEMD电力变压器局部放电去噪方法。该方法基于两路同时采集的局部放电信号 ...

Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...

Jixie chuandong, 1992 抛弃把轮齿形状视为悬臂梁的假设和引入应力集中系数的方法,直接从实际齿形和相似理论出发,建立齿根最大拉应力计算公式:σFO=Ft/（b·mn）·YFR。通过采用边界元法计算出样本空间中各种齿数z,各种径向变位系数xn及各种载荷作用高度ef下的真实齿形系数YFR。采用三元回归分析得出YFR的回归公式。设计者即可方便地计算任意z、xn、ef下的齿根最大拉应力σFO。其中单齿对接触区外侧点的ef值可由端面重合度εa算出。新方法克服了ISO6336方法中的许多缺陷,具有更为先进准确和方便的突出优点 ...
