Moirésuperlattices of transition metal dichalcogenide(TMD)heterostructures give rise to rich excitonic phenomena associated with the interlayer twist *** calculations of excitons in such systems are typically based on model moirépotentials that mitigate the computational ***,predictive understanding of the electron-hole coupling dominating the excitations is crucial to realize the twist-induced modifications of the optical selection *** this work,we use many-body perturbation theory to evaluate the relation between twist angle and exciton properties in TMD *** present an approach for unfolding excitonic states from the moiréBrillouin zone onto the separate-layer *** this method to a large-angle twisted MoS^(2)/MoSe^(2) bilayer,we find that the optical spectrum is dominated by mixed electron–hole transitions with different momenta in the separate monolayers,leading to unexpected hybridization between interlayer and intralayer *** findings offer a design pathway for exciton layer-localization in TMD heterostructures.

为了研究农业区面污染造成的河流水体污染和富营养化等问题,以离子型为主的硝态氮污染物的质量浓度与径流大小的变化关系为河流水体含氮量预报的基础,选择农业区密集的美国密西西比河下游为研究对象,观测干流上控制性水文站维克斯堡站,对收集到的相关径流和水体硝态氮资料进行分析;运用Baseflow基流分割程序对径流序列分别进行日、月基流分割,将所分割的基流运用耶鲁大学Loadrunner程序,延伸和补全所选站点水体硝态氮的逐日质量浓度序列,并进一步建立逐月数据序列;运用神经网络方法,对研究对象的水体月硝态氮质量浓度进行了验证预报,建立了相应的预报步骤与预报公式.预报结果显示:对密西西比河下游水体月硝态氮质量浓度预报平均误差为7.5%.由此可见所提出的步骤和方法的准确性与适用性,可用于实际的河流水体月硝态氮质量浓度预报.

首先，结构转变是与产品品种的变化相关。顾客要求在短时间内得到他个人所需要的产品以及与此相应的“全套服务”。如同适合于服务性行业那样，这也适合于传统意义上的商品。其次，生产商和销售商不再同时束缚于国家和文化的界限。可以在世界各地购买产品，并且只要当地的资源合理，便可在那里生产。因此，信息、通信和市场研究起着越来越重要的作用．
