毛竹扩张对南亚热带常绿阔叶林土壤跳虫群落特征的影响

2018年中西部地区无机化学化工学术研讨会

作者： lin li Qi Luo Huahua Cui renjie li Jing Zhang Tianyou Peng College of Chemistry & Molecular Sciences Wuhan University

Two new phosphine-free Ru(Ⅱ)-NNN pincer complexes ([RuCl(L1)(CHCN)]Cl (1) and[RuCl(L2)(CHCN)]Cl (2),L1=2,6-bis(1H-imidazole-2-yl)pyridine,L2=2,6-bis(1-hexyl-1H-imidazole-2-yl)-pyridine) were synthesized for homogeneously catalyzing the condensation of benzyl alcohol and benzene-1,2-diamine to 2-pheny-1H-benzo[d]imidazole and *** was found that the reactivity with an order of 1>2 is lower than that of the phosphine-containing Ru(Ⅱ)-NNN pincer complex[RuCl(L1)(PPh)](3),and thus a homogeneous system containing complex 1,1 *** 1,2-bis(diphenyl-phosphanyl)ethane (dppe),and 10 *** NaBPh was developed to improve the catalytic efficiency for the condensation of primary alcohols and benzene-1,2-diamine (or its derivatives) to 2-substituted 1H-benzo[d]imidazoles in excellent yields (up to 97%)and turnover number (TONs～388).The present system realizes facile one-step synthesis of1H-benzo[d]imidazole derivatives from alcohols without using the oxidant and/or the stoichiometric amount of inorganic bases that is usually necessary in homogeneous systems reported previously

以广州市流溪河国家森林公园内的毛竹林、竹阔混交林和常绿阔叶林为研究对象,探讨2018—2019年的旱、雨季,毛竹扩张对土壤理化性质的影响,及其引起的土壤跳虫群落特征的改变。研究结果显示:①共捕获土壤跳虫4455头,隶属于12科27属,其中,符跳属、拟裸长角跳属和小圆跳属为优势属。②3种类型样地中土壤跳虫的个体密度和类群数均为雨季高于旱季。旱季所有指标在不同林分类型之间无显著差异。雨季土壤跳虫的个体密度、类群数、Shannon⁃Weiner多样性指数、Simpson优势度指数和Margalef丰富度指数均表现为毛竹林>竹阔混交林>常绿阔叶林,Pielou均匀度指数为竹阔混交林>毛竹林>常绿阔叶林。③随着毛竹扩张,凋落物层的β-葡糖苷酶、酸性磷酸酶、β-乙酰葡糖胺糖苷酶和土壤有机碳显著降低,导致土壤跳虫的个体密度、类群数显著增加,多样性亦增加,但扩张中过渡类型的竹阔混交林跳虫多样性减少。毛竹扩张不同阶段中土壤跳虫的大部分优势属和常见属相同,表明土壤跳虫群落在毛竹扩张过程中具有一定的稳定性。

在粒子群算法和鲸鱼群算法等进化算法中,代际之间的信息传递仅限于相邻2代个体之间,导致全局搜索参考信息单一,难以探索所有可行搜索区域并获得最优结果。本文提出一种全新的启发式算法:非洲蜂优化算法,该算法模拟了非洲蜂种群在迁徙过程中遇到威胁时的反应模式、蜂王的指令模式与记忆模式,借此实现最优化求解。为了验证非洲蜂优化算法的有效性,本文选择23种标准函数进行了对比实验,实验结果表明非洲蜂优化算法在保留较高收敛速度的同时,也保证了较好的收敛精度。

河南省化学会2018年学术年会

作者： Gang Mi renjie li Yang Wang Yana Dong Jun Zhang Chemical Engineering and Pharmaceutics School Henan University of Science and Technology

Transition metal chalcogenides have been widely applied in many fields such as water splitting, catalysts, optical sensors and thermalelectric. Among them, the sulfides and selenides were more reported in the literatures than the tellurides in last decades. However, the transition metal telluride, such as nickel telluride and cobalt telluride, has attracted considerable interest in recent years duo to their potential applications in hydrogen evolution reaction(HER) and dehydrogenation of ammonia borane(AB) [1-2]. Moreover, nano morphology of transition metal telluride has a great influence on its properties. Thus, it’s significant to synthesize the transition metal telluride with controllable nanostructures. Here, series of one-dimensional CoTe nanostructures, such as nanowires(diameter ～7 nanometers), nanorods(～ 40 nm), nanotubes(～ 40 nm), were prepared by two step solvothermal method. PVP and N H·H O were employed as surfactant and reducing agent, respectively. The morphology could be easily modulated by varying reaction conditions under Nitrogen atmosphere and the products were high purity, perfectly crystalline and uniform shape. In addition, the results of catalytic activities for dehydrogenation of AB indicated that the CoTe nanowires had the best catalytic effect due to high specific surface area.

休谟的欲望信念模型提出了一种对人类行动心理的经典理解。在其基础上,威廉斯提出了一种休谟主义的行动理由内在主义。威廉斯的内在主义反对行动理由解释性和规范性的分离,坚持行动理由必须经由行动者从主观动机集合出发的合理慎思而得到。科斯佳、内格尔、麦克道威尔等人则认为,休谟主义的内在主义可能无法满足内在主义要求,并且存在着行动理由规范性不足的问题。威廉斯对休谟的工作有所发展,但其内在主义可能仍存在不足。从休谟主义的立场出发,可以对科斯佳和内格尔为主的批评者进行回应。在威廉斯的基础上发展休谟主义的内在主义,提出五条实践慎思的规范性原则,有助于更好地解决休谟主义的规范性问题。

为提高热误差预测精度和鲁棒性,提出一种基于注意力机制和深度学习网络的数控机床热误差预测模型。采用数据转化策略,将数控机床原始温度数据转化为温度图像,直接作为深度学习网络的输入;提出一种基于注意力机制的温度敏感点识别网络,根据温度测点与热误差关联程度,赋予各温度测点不同的权值,避免了温度测点人为选取的弊端;建立12层深度CNN学习预测网络,利用其强大的图像特征学习能力,挖掘温度图像与热误差的非线性映射关系,无需对温度关键点进行预选择,保留了更多的热误差与机床温度特征关系,显著提高了模型预测精度。引入Dropout正则化方法和Adam优化算法,对深度卷积神经网络的结构与参数进行了优化,以提高热误差模型的精度与泛化能力。该方法在对G460L型数控车床的热误差验证中表现出较高的预测精度。与基于BP神经网络、多元回归、CNN网络等热误差模型比较,本文方法在泛化性性能上表现更优。
