Annealing has been widely recognized as a crucial approach to modify the microstructure and enhance the coercivity of Nd–Fe–B magnets. However, in the context of Nd–Y–Ce–Fe–B magnets with multiple rare earths(REs) exhibiting different diffusion behaviors, annealing effects on the magnetic properties become more complicated and remain unknown.

通过引入虚时间变量,将绝对零度附近的金兹堡−朗道方程推广为一个精确的相对论方程。基于该方程所建立的虚时量子场论,描述过掺杂铜氧化物超导材料在绝对零度附近的量子临界现象。利用虚时量子场论框架,理论推导出在La_(2-x)Sr_(x)CuO_(4)超导薄膜的过掺杂区域所观测到的零温超流相位刚度与相变温度之间的反常两段标度,且理论计算结果与实验测量值吻合良好。该研究推测:处于绝对零度附近的过掺杂超导薄膜中,零温相干长度与相变温度也服从一个两段标度,理论得到的两个临界指数1和1.34有待实验的检验。

小麦的茎秆性状与倒伏紧密相关,发掘其显著关联的基因位点和候选基因,为解析小麦茎秆性状的遗传机制和分子标记辅助育种提供依据。本研究以黄淮南部地区的192份小麦品种为材料,利用小麦660KSNP芯片对7个环境成熟期和4个环境灌浆中期的14个茎秆性状进行了全基因组关联分析(GWAS),同时利用RNA-seq分析了基部前二节间强度和直径的差异表达基因。结果表明,所有性状的成熟期与灌浆中期的差异均达到极显著水平。与灌浆中期相比,成熟期的重心高度增幅较大,基部第二和第三节间长度增加,其他性状均降低。GWAS共检测出163个与茎秆性状相关的稳定SNP标记(MTA),其中45个具有基因或蛋白注释,与转录组联合分析,共筛选到3个与小麦茎秆性状相关的候选基因。推测候选基因TraesCS5A02G522100通过合成异戊二酸类化合物调节小麦的光合作用以及通过调节固醇的生成提高细胞膜的稳定性和渗透性,进而促进茎秆的发育,改善茎秆性状。候选基因TraesCS1D02G390600直接参与小麦茎秆细胞分裂和器官的形成,使茎秆变粗,充实度增加。候选基因TraesCS7A02G481800在小麦中通过参与细胞间的信号传递过程,调控茎秆的发育、应激响应等过程。这些候选基因通过qRT-PCR验证,其基因的表达趋势与转录组测序所得结果基本一致。

水体中的亚甲基蓝分子对生态环境造成了严重的危害,也在一定程度上威胁着人类的健康。本文以油页岩加工的副产物油页岩灰渣为原料,采用碱熔融-水热合成法合成了Na-X型沸石,并探讨导向剂的使用量、NaOH的用量、水热温度、水热时间和酸浸浓度对沸石结晶度的影响,最终得到合成沸石的最佳条件。用合成的Na-X型沸石处理水溶液中亚甲基蓝分子,得到吸附平衡数据采用吸附等温线和吸附动力学模型进行拟合。结果表明,朗格缪尔等温线模型和伪二阶动力学模型与亚甲基蓝的吸附数据相吻合,表明Na-X型沸石对亚甲基蓝的吸附过程属于单层的化学吸附过程。综上所述,由油页岩灰渣制备的Na-X型沸石材料可作为吸附水溶液中亚甲基蓝分子的吸附剂。

Hydrocarbon source rocks, as a main geologic factor of petroliferous systems in a sedimentary basin, play a key role in the accumulation of oil and gas and the formation of hydrocarbon accumulations. This study, which focuses on difficulties in prediction of hydrocarbon source rocks in basins or sags with low exploration degree and insufficient hydrocarbon source rock indicators, taking the Wenchang Formation of northern Zhu I Depression, Pearl River Mouth Basin as an example, proposed a hypothesis of “finding lakes and hydrocarbon source rocks”. Detailed steps include, first, determination of the lacustrine basin boundary according to analysis of seismic foreset facies, determination of the depositional area based on the compilation of strata residual thickness maps, determination of the lacustrine basin shape according to deciphering slope break belt system, determination of the fluctuation of paleo-water depth according to biogeochemical indicators of mature exploration areas, determination of the lacustrine basin scale based on analyses of tectonics intensity and accommodation space, which prove the existence of the lacustrine basin and identify the range of semi deep-deep lake;second, further analyses of tectonopalaeogeomorphology, paleo-provenance,palaeoclimate and paleo-water depth to reconstruct the geologic background of the original basin and semideep-deep lacustrine facies, to determine the distribution of semi-deep/deep lacustrine sediments in combination with studies of logging facies, core facies, seismic facies and sedimentary facies, and to rank the sags’ potential of developing hydrocarbon source rocks from controlling factors of source-to-sink system development;third, on the basis of regional sedimentary facies analysis, through identification and assessment of seismic facies types of semi-deep/deep lacustrine basins in mature areas, establishing “hydrocarbon source rock facies” in mature areas to instruct the identification and depicting of hydro
