土壤螨群落沿山地海拔梯度分布格局是生物地理学研究的重要内容,但是目前的研究主要关注土壤层中土壤螨群落,忽略了多样性更丰富的凋落物层.为了阐明凋落物层和土壤层中土壤螨群落沿海拔梯度的分布格局,于2.2.年5月在天目山沿海拔364.33~1476.2.m的12.样地采集了凋落物层和土壤层中土壤螨样品.分析结果表明:(1)样品中共捕获土壤螨7172.,84种,优势物种为副小单翼甲螨,土壤螨群落物种数、个体数总体呈现先增后减趋势.(2.在凋落物层土壤螨的margalef丰富度指数、Shannon-Weiner多样性指数和Simpson优势度指数沿海拔梯度变化显著,呈现单峰分布;而土壤层土壤螨的多样性指数沿海拔梯度变化不显著.表明凋落物层和土壤层土壤螨多样性沿海拔梯度的分布格局有所不同.建议在亚热带山地同时开展凋落物层与土壤层土壤动物多样性的海拔梯度分布研究,为山地土壤动物群落多样性对全球变化响应提供更丰富的基础数据.

Although the water splitting-based generation of hydrogen as an energy carrier can help to mitigate the global problems of energy shortage and climate change,the practical implementation of this strategy is hindered by the absence of inexpensive high-performance electrocatalysts for the hydrogen evolution reaction (heR).Re-based heR electrocatalysts exhibit predictable high performance within the entire pH range but suffer from arduous formation (i.e.,vulnerability to oxidation) and uncontrollable aggregation,which strongly discourages the maximisation of active site exposure required for activity *** overcome these limitations,we herein hydrothermally synthesise Re nanoclusters uniformly distributed on nanosheet supports,such as reduced graphene oxide nanosheets (Re NCs@rGO),revealing that this hybrid features abundant exposed active sites and high oxidation *** obtained electrocatalysts were elaborately characterized by microscopic and spectroscopic ***,density functional theory calculations confirm the optimised synthesis of Re NCs@rGO and indicate the crucial role of Re–O–C junction formation in securing *** effective suppression of Re nanocluster detachment/dissolution under heR conditions endows Re NCs@rGO with high electron conductivity and electrochemical stability,resulting in a durability superior to that of commercial Pt/C and an activity similar to that of this *** a result,Re NCs@rGO exhibited remarkably small heR overpotentials of 110,130,and 93 m V to deliver a current density of 10 ma cm^(-2. in 0.5 M H_(2.SO_(4),1 M PBS,and 1 M KOH,***,Re NCs@rGO is a promising alternative to conventional Pt-group-metal catalysts and should find applications in next-generation high-performance water splitting systems.

材料数据由于小样本、高维度、噪音大等特性,用于机器学习建模时常常会产生与领域专家认知不一致的结果。面向机器学习全流程,开发材料领域知识嵌入的机器学习模型是解决这一问题的有效途径。材料数据的准确性直接影响了数据驱动的材料性能预测的可靠性。本研究针对机器学习应用过程中的数据预处理阶段,提出了融合材料领域知识的数据准确性检测方法。该方法首先结合材料专家认知构建了材料领域知识库。然后,将其与数据驱动的数据准确性检测方法结合,从数据和领域知识两个角度对材料数据集进行基于描述符取值规则的单维度数据正确性检测、基于描述符相关性规则的多维度数据相关性检测以及基于多维相似样本识别策略的全维度数据可靠性检测。对于每一阶段识别出的异常数据,结合材料领域知识进行修正,并将领域知识融入到数据准确性检测方法的全过程以确保数据集从初始阶段就具有较高准确性。最后该方法在NASICON型固态电解质激活能预测数据集上的实验结果表明:本研究提出的方法可以有效识别异常数据并进行合理修正。与原始数据集相比,基于修正数据集的6种机器学习模型的预测精度都有不同程度的提升。其中,在最优模型上R2.升了33%。

利用EPma、EBSD、XRD、TEM和热压缩测试,研究了Y元素对无取向6.5%Si钢铸态组织、有序相、中温变形和软化机制的影响。结果表明,当Y含量为0.017%和0.15%时,钢液中形成高熔点Y_(2.O_(3)+Y_(2.O_(2.S/Y_(2.O_(2.S-YP复合稀土化合物,促进异质形核。凝固末期,枝晶间形成Y_(2.Fe_(14)Si_(3)化合物,凝固组织得到明显细化。铸锭的基体有序度与Y含量呈反比关系。500℃压缩实验结果表明,不同Y含量铸锭的塑性变形均由位错滑移机制主导。含Y试样峰值应力对应的临界应变降低,加工软化提前,加工硬化率下降,动态软化作用增强。热压缩试样的位错密度正比于Y含量,低基体有序度和高形变诱导无序作用是含Y试样动态软化作用增强的主要原因。
