Gongye shui chuli, 1988 循环冷却水补充水量的多少，是循环系统节水程度的重要标志。本文提出当循环冷却水中投加各种水质稳定剂时，为防止在循环水中可能产生各种水垢，循环冷却水补充水量的计算方法。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Laser powder bed fusion (LPBF) can fabricate high‐entropy alloys (HEAs) with refined microstructure and enhanced mechanical properties. However, the deformation and fatigue mechanisms of Al‐containing HEAs produced by LPBF remain unclear. In this work, we systematically investigate the tensile properties, deformation mechanisms, and high‐cycle

Gongye shui chuli, 2002 循环水管理中存在的突出问题主要是循环水场硬件设施陈旧、老化,凉水塔排泥设施不完善,池底淤泥无法排掉 ；生产装置乱排乱放现象严重 ；一催冷 30 3/ 1- 30 3/ 4冷却效果差 ；气体分馏车间冷 10 8因循环水管层堵塞而冷却效果差。需要增加循环水场的投入,完善循环水处理设施,加强循环水管理,提高循环水的处理效果。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.

Gongye shui chuli, 1987 在工业用水总量中循环冷却水量约占60～80％，因此，减少循环冷却水的补水量，对于减少整个工业用水量，降低万元产值耗水量意义十分重大。变直流水为循环水，提高循环水系统的浓缩倍数是减少循环冷却水补水量的主要途径。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

Functional Ecology, Volume 40, Issue 5, Page 1415-1427, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Wildfires are disrupting and regenerating forces in nature that affect all ecosystem components. However, the impact of wildfires on soil multitrophic biodiversity and the resulting consequences for ecosystem multifunctionality (EMF) remain poorly understood.

Gongye shui chuli, 2006 介绍了烟台发电厂投入运行的循环冷却排污水的深度处理系统，该系统由预处理、预除盐、一级除盐、深度除盐等部分组成，它以电厂的循环排污水作为水源制取除盐水，与原有的水处理车间的除盐水一起供应烟台市供热管网首站用水和电厂锅炉用水。系统投入运行后降低了循环水的浓缩倍数，改善了循环水的运行工况，解决了电厂中循环水排污水处理难的问题，实现了循环冷却排污水的回收利用，达到了循环水的零排放，提高了水利用率，降低了电厂的水耗。
