Kear Editor,Individuals in isolated,confined,and extreme environments,such as astronauts,researchers wintering over Antarctica,submarine soldiers,and participants in simulated isolation environment experiments,commonly report difficulty in focusing their attention[1,2].However,current experimental findings from studies conducted in such environments are insufficient to fully support these self-reports of reduced *** attention-demanding tasks such as simple reaction time(RT)tasks and dual tasks,including primary pursuit tracking and secondary RT,were not affected in space flight experiments[2,3].

宁夏平原干旱的自然条件使得水利供给必然要依靠效率远高于私人小水利的大水利系统,干旱缺水的自然条件使得农民没有等待降雨的侥幸心理和退出大水利灌溉的自然空间。共同的水利灌溉需求以及地缘关系使得乡村社会形成了公共水利秩序,通过交水费的公共舆论、集体灌溉的"一把锹"和集体义务工共同维护着地方的水利秩序。干旱地区的水利作为农民的公共必需品,使得水利供给成为了地方政府的政治责任,从而在干旱地区出现了政治动员下的义务工水利维修和政治兜底下的用水者协会运作。干旱地区的水利供给更为困难和复杂,需要农民、乡村社会和基层政权投入更多,进行更为高效协调的公共灌溉和排涝。

吐鲁番博物馆藏汉文印本佛典主要刊布在《吐鲁番柏孜克里克石窟出土汉文佛教典籍》一书中,通过对这些印本的考察,从已定名及未定名印本佛典中又比对出几件《契丹藏》佛经残片。对其中新发现的《囉嚩拏救疗小儿疾病经》残片进行了考释,认为吐鲁番《契丹藏》传入时间上限应在11世纪末至12世纪初,其下限应在12世纪末,这些残片的发现表明了古代高昌地区佛教文化来源的多样性。

Soft magnetic composites(SMCs)play a pivotal role in the development of high-frequency,miniaturization and complex forming of modern ***,they usually suffer from a trade-off between high magnetization and good magnetic softness(high permeability and low core loss).In this work,utilizing the order modulation strategy,a critical state in a FeSiBCCr amorphous soft magnetic composite(ASMC),consisting of massive crystal-like orders(CLOs,∼1 nm in size)with the feature ofα-Fe,is *** critical-state structure endows the amorphous powder with the enhanced ferromagnetic exchange interactions and the optimized magnetic domains with uniform orientation and fewer micro-vortex *** comprehensive soft magnetic properties at high frequency emerge in the ASMC,such as a high saturation magnetization(Ms)of 170 emu g^(-1)and effective permeability(µ_(e))of 65 combined with a core loss(Pcv)as low as 70 mW cm^(-3)(0.01 T,1 MHz).This study provides a new strategy for the development of high-frequency ASMCs,possessing suitable comprehensive soft magnetic performance to match the requirements of the modern magnetic devices used in the third-generation semiconductors and new energy fields.
