Remote sensing spectral of igneous rocks from Xinchang county, Zhejiang Province and their forming mechanism(浙江新昌主要火成岩类的遥感光谱与形成机理)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2007
新昌盆地地处中国东南沿海火山-侵入杂岩带的东北端,区内广泛出露晚中生代火山岩与使入岩类,岩石类型丰富,是研究岩石遥感光谱的理想地区.作者对该地区的岩石样品进行了可见-近红外光谱和热红外光谱分析测试,研究了火成岩矿物组成、蚀变特征、共生状态等与遥感光谱的关系,并对其形成机理进行了探讨.

Designing Additive‐Manufactured High‐Performance CoCrNi Matrix Composites Based on Grain Boundary Segregation

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Through grain boundary segregation engineering, a crack‐free high‐strength CoCrNi medium‐entropy alloy (MEA) can be successfully fabricated via laser powder bed fusion (PBF‐LB). The influence of micron‐sized TiC particles on microstructural evolution, grain boundary segregation behavior, and mechanical properties was systematically ...

Relative Habitat Suitability of the Gray Fox (Urocyon cinereoargenteus) in the Central Great Plains 大平原中部灰狐 (Urocyon cinereoargenteus) 的生境相对适宜性

open access: yesWildlife Letters, Volume 4, Issue 2, Page 94-101, June 2026.
Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

论降雨径流的集存

open access: yesShuitu Baochi Xuebao, 1994
降雨径流集存系统由集水、输水和存水三个子系统组成,它把大面积集水区的降雨径流汇集到小面积存水区的土壤水库中,变少雨为多水,是半干旱与干旱地区利用降雨径流资源发展旱作农业的高效系统。根据农田土壤水分平衡方程和植物需水量与供水量的对比关系可以定量确定系统中存水区与集水区的面积比。小型径流场、集流梯田和微型集水区是当前使用最多,效果最好的降雨径流集存形式。

Divine intimacy, frustration and the madness of the city: Changing transhuman kinship in China

open access: yesEthos, Volume 54, Issue 2, June 2026.
This essay shows the affective resonances of the collision of gods, humans, and rapidly shifting landscapes in a newly urbanized part of Suzhou, China. The first section discusses how ties to spirits are not just metaphors or projections of human kinship, but literal parts of a kinship system that invoke responsibilities of care, based on links of both

Superior Abrasibility of YSZ(ESP)/BN@ZrO2‐Polyester Composite Sealing Coating Reinforcing With Hybrid Micron/Nanometer Multiscaled Pore Structure

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...
