作者： jin-fang Ma Guang-wei Wang jian-liang Zhang xin-yu Li Zheng-jian Liu Ke-xin Jiao jian Guo School of Metallurgical and Ecological Engineering University of Science and Technology Beijing Plans and Operations Department Wanbao Mining Ltd.

In this work, the reduction behavior of vanadium–titanium sinters was studied under five different sets of conditions of pulverized coal injection with oxygen enrichment. The modified random pore model was established to analyze the reduction kinetics. The results show that the reduction rate of sinters was accelerated by an increase of CO and H2contents. Meanwhile, with the increase in CO and H2contents, the increasing range of the medium reduction index (MRE) of sinters decreased. The increasing oxygen enrichment ratio played a diminishing role in improving the reduction behavior of the sinters. The reducing process kinetic parameters were solved using the modified random role model. The results indicated that, with increasing oxygen enrichment, the contents of CO and H2in the reducing gas increased. The reduction activation energy of the sinters decreased to between 20.4 and 23.2 kJ/mol. © 2017, The Author(s).

Lithium-ion batteries(LIBs)have dominated the portable electronic and electrochemical energy markets since their commercialisation,whose high cost and lithium scarcity have prompted the development of other alkali-ion batteries(AIBs)including sodium-ion batteries(SIBs)and potassium-ion batteries(PIBs).Owing to larger ion sizes of Na^(+)and K^(+)compared with Li^(+),nanocomposites with excellent crystallinity orientation and well-developed porosity show unprecedented potential for advanced lithium/sodium/potassium *** enticing open rigid framework structures,Prussian blue analogues(PBAs)remain promising self-sacrificial templates for the preparation of various nanocomposites,whose appeal originates from the well-retained porous structures and exceptional electrochemical activities after thermal *** review focuses on the recent progress of PBA-derived nanocomposites from their fabrication,lithium/sodium/potassium storage mechanism,and applications in AIBs(LIBs,SIBs,and PIBs).To distinguish various PBA derivatives,the working mechanism and applications of PBA-templated metal oxides,metal chalcogenides,metal phosphides,and other nanocomposites are systematically evaluated,facilitating the establishment of a structure–activity correlation for these *** on the fruitful achievements of PBA-derived nanocomposites,perspectives for their future development are envisioned,aiming to narrow down the gap between laboratory study and industrial reality.

作物长势和田间水分预测对于农业精准管理至关重要。为准确模拟宁夏玉米产量,利用2019-2020年田间观测数据,整合SWAP(soil-water-atmosphere-plant)模型和迭代集成平滑算法(iterative ensemble smoother,IES)构建了适用于宁夏干旱地区玉米的SWAP-IES作物同化模型。比较了同化叶面积指数(leaf area index,LAI)、土壤含水率(soil water content,SW)及其组合对宁夏干旱地区玉米种植区土壤含水率模拟和产量估算的影响。研究结果表明,当同时同化LAI和SW数据时,土壤含水率模拟的决定系数(R2)显著提升,从初始时的-0.07增加到0.71。这表明,将LAI和SW数据同时纳入模型显著增强了模型预测土壤含水率的准确性。而同时同化LAI和SW相比仅同化LAI或SW能更好的模拟土壤含水率,这表明2个观测变量之间并不是孤立的,二者的耦合能更好地提升模型的模拟精度。同时同化LAI和SW时估产精度最高,RMSE降低到914.113 kg/hm^(2),显著低于其他情景。说明所构建的SWAP-IES玉米同化模型,在同时同化LAI和SW的情况下,可以准确模拟土壤含水率变化过程和玉米产量,为干旱地区农田灌溉优化和玉米估产提供参考。

The effect of martensite–austenite(M–A)constituents formed in thermo-mechanical controlled process on impact toughness of 20CrNi2MoV steel was *** variation in fraction,size and morphology of M–A constituent and its effect on toughness under different cooling rates were carried *** result shows that there was no significant change in the fraction of M–A constituent under different cooling rates,but the distribution and size of M–A constituent were greatly influenced by cooling rate,which consequently influenced *** amount of large blocky M–A constituents decreased from 4.7%to 1.7%,while that of elongated M–A constituents increased from 3.8%to 8.6%with the cooling rate increasing from 7 to 26°C/s,and the corresponding impact energy decreased from 132 to 84 *** deterioration of impact toughness could be related to the increase in the elongated M–A *** elongated M–A constituents existing along the prior austenite grain boundaries in samples of 26°C/s could easily lead to the formation of cleavage crack,which then results in the lower crack initiation energy than that of low cooling rate samples.
