制备一种新型Al−10Nb−3Ce−2.5B孕育剂,并系统研究其对锌铝共析(ZA22)合金显微组织、阻尼和拉伸力学性能的影响。结果表明,该孕育剂对ZA22合金中的α相具有显著的细化作用(α相最低可被细化至约16μm),并可使得α相的形貌从粗大枝晶状转变为细小花瓣状。通过边−边匹配晶体学模型(E2EM)建立孕育剂中CeB_(6)和NbB_(2)颗粒与α相之间的位向关系(ORs),并基于该E2EM模型揭示孕育剂对ZA22合金的细化机理。与未细化ZA22合金相比,孕育细化ZA22合金的高温阻尼性能,特别是逆共析转变阻尼峰得到显著提升。此外,孕育细化ZA22合金的室温拉伸力学性能也得到了显著提高,具有最佳细化效果的ZA22合金的抗拉强度和伸长率分别比未细化ZA22合金的高18.56%和119.04%。对相关机理进行了讨论。

[背景]邻苯二甲酸二异癸酯(DiDP)是一种新型增塑剂,可经多种途径进入人体。目前国内对DiDP肾毒性作用的研究不多,DiDP是否可通过氧化应激导致受试动物发生肾损伤尚不清楚。[目的]探讨不同剂量的DiDP暴露对雄性Balb/c小鼠肾脏的影响及可能机制。[方法]Balb/c小鼠随机分为空白对照组(生理盐水)、不同剂量DiDP组(0.15、1.5、15、150 mg/kg)、Vit E组(100 mg/kg)、联合处理组(150 mg/kg DiDP+100 mg/kg Vit E)共7组,每组8只。灌胃染毒14 d后,观察肾组织切片病理学变化,检测肾组织活性氧(ROS)、丙二醛(MDA)、还原型谷胱甘肽(GSH)、8-羟基脱氧鸟苷(8-OHdG)和血清尿素氮(UREA)、肌酐(CREA)水平。[结果]与空白对照组比较,150 mg/kg DiDP组小鼠肾组织ROS、MDA、8-OHd G水平及血清UREA、CREA含量升高,GSH水平降低,差异均有统计学意义(P<0.05);肾组织切片结果显示Di DP剂量越高,肾脏损伤越严重。加入Vit E干预后,与150 mg/kg DiDP组比较,联合处理组小鼠肾组织ROS、MDA、8-OHd G水平及血清UREA、CREA含量下降,GSH水平上升,差异均有统计学意义(P<0.05),同时肾组织切片结果也显示Vit E可在一定程度上降低150 mg/kg DiDP造成的肾损伤。[结论]DiDP可能通过氧化应激途径导致受试小鼠肾组织发生病理损伤。

CSEE Journal of Power and Energy Systems 2021年第1期7卷 66-77页

作者： ji Qiao Tianjiao pu Xinying Wang the China Electric Power Research Institute Haidian DistrictBeijing 100192China

With the growing penetration of renewable energysources in power systems, it becomes increasingly important tocharacterize their inherent variability and uncertainty. Scenariogeneration is a key approach to provide a series of possible powerscenarios in the future for the system planner and operator tomake decisions. In this paper, a data-driven method is presentedfor renewable scenario generation using stable and controllablegenerative adversarial networks with transparent latent space(ctrl-GANs). The machine learning based algorithm can capturethe nonlinear and dynamic renewable patterns without the needfor modeling assumptions and complicated sampling *** orthogonal regularization and spectral normalization areadopted to improve the training stabilization of the GAN *** control the generation process, a relationship is built betweenfeatures of the generated scenarios and latent vectors on themanifold. Moreover, several new metrics for GANs are used toevaluate the quality of the scenarios. The proposed approachis applied to generate realistic time series data of wind andphotovoltaic power. The results demonstrate that our methodhas a better performance on numerical stabilization and is ableto control the generation process with latent space.

A Genetic Map Constructed Using a Doubled Haploid Population Derived from Two Elite Chinese Common Wheat Varieties

引用

Journal of Integrative Plant Biology 2008年第8期50卷 941-950页

作者： Kun-pu Zhangi Liang Zhao ji-Chun Tian guang-Feng Chen Xiao-Ling jiang Bin Liu State Key Laboratory of Crop Biology Group of Quality Wheat Breeding of Shandong Agricultural University Tai'an 271018 China Department of Agriculture Dezhou University Dezhou 253015 China

Genetic mapping provides a powerful tool for the analysis of quantitative trait loci （QTLs） at the genomic level. Herein, we report a new genetic linkage map developed from an F1-derived doubled haploid （DH） population of 168 lines, which was generated from the cross between two elite Chinese common wheat （Triticum aestivum L.） varieties, Huapei 3 and Yumai 57. The map contained 305 loci, represented by 283 simple sequence repeat （SSR） and 22 expressed sequence tag （EST）-SSR markers, which covered a total length of 2141.7 cM with an average distance of 7.02 cM between adjacent markers on the map. The chromosomal locations and map positions of 22 new SSR markers were determined, and were found to distribute on 14 linkage groups. Twenty SSR loci showed different chromosomal locations from those reported in other maps. Therefore, this map offers new information on the SSR markers of wheat. This genetic map provides new opportunities to detect and map QTLs controlling agronomically important traits. The unique features of this map are discussed.

The new Chinese hypertension guideline was eventually published.[1] It has been more than seven years since the previous Chinese hypertension guideline was published in 2011.[2] The guideline committee should also be congratulated that this new Chinese hypertension guideline was for the first time published in full length in the English language in this issue of the Journal of Geriatric Cardiology.[3] This is the fourth Chinese hypertension guideline,[3] after the first,second[4] and third[2] in 1999,2005 and 2011,*** first Chinese hypertension guideline was printed in a *** document was not so sophisticated,but nevertheless played a role in improving management of hypertension at that time in *** treatment rate of hypertension increased substantially from 45.5% in 1991[5] to 81.8% in 2002[6] in patients who were aware of the disease (Table 1).

Three-dimensional spin–orbit coupled Fermi gases:Fulde–Ferrell pairing, Majorana fermions, Weyl fermions,and gapless topological superfluidity

Chinese Physics B 2015年第5期24卷 44-55页

作者： Xia-ji Liu Hui Hu Han pu Center for Quantum and Optical Science Swinburne University of Technology Department of Physics and Astronomy and Rice Quantum Institute Rice University Center for Cold Atom Physics Chinese Academy of Sciences

We theoretically investigate a three-dimensional Fermi gas with Rashba spin-orbit coupling in the presence of both out-of-plane and in-plane Zeeman fields. We show that, driven by a sufficiently large Zeeman field, either out-of-plane or in-plane, the superfluid phase of this system exhibits a number of interesting features, including inhomogeneous Fulde- Ferrell pairing, gapped or gapless topological order, and exotic quasi-particle excitations known as Weyl fermions that have linear energy dispersions in momentum space （i.e., massless Dirac fermions）. The topological superfluid phase can have either four or two topologically protected Weyl nodes. We present the phase diagrams at both zero and finite temperatures and discuss the possibility of their observation in an atomic Fermi gas with synthetic spin-orbit coupling. In this context, topological superfluid phase with an imperfect Rashba spin-orbit coupling is also studied.
