ObjectivernNumerous vertebrate fossils,dominated by the Mammuthus-Coelodonta fauna,have been found from many Late Pleistocene fossil sites in Heilongjiang,northeast China(Jin and Kawamura,1996).However,fossil turtles have not yet been reported.Recently,two soft-shelled turtle(trionychid)costal plates have been discovered together with other typical Mammuthus-Coelodonta fauna fossils.rnSoft-shelled turtle fossil remains are scarce in northeast China.To date,only three taxa(Khunnuchelys erinhotenisis,Perochelys lamadongensis,“Trionyx”jixiensis)have been reported from Cretaceous deposits(Li and Tong,2017).Cenozoic soft-shelled turtle fossils are extremely rare and have not received any formal description.The specimens we describe in this study fill a noticeable gap in the soft-shelled turtle fossil record of the Cenozoic of northeast China,which provides new fossil data for studying the diversity and stratigraphic distribution of the group.

近年来,利用金属纳米结构表面等离激元共振提高半导体材料的发光效率取得了重要进展,但是相关结构体系面临着加工技术复杂、重复性差等缺点。本文报道了一种新型超薄、大面积、共振可调的平面双层纳米媒质用于增强量子点发光,其结构由深亚波长厚度、高吸收率特性的氧化铜(CuO)薄膜和金(Au)薄膜构成。实验结果显示,通过改变CuO薄膜厚度可以灵活调节CuO/Au双层堆栈结构的反射光谱,以其为基底旋涂CsPbBr3钙钛矿量子点后与裸石英旋涂CsPbBr3量子点参考样品相比实现了最

在大多数人的印象中,数学就是“做题”,数学就是“脑筋急转弯”.然而数学是每一个孩子从求学开始都必须要学习的一门主要课程,它教给孩子们的不应只是冰冷的数学知识,更重要是要教给学生用数学的眼光看待问题、用数学的思想去思考问题,用数学的方法去解决问题.课程改革明确指出教师应引导学生主动地经历观察、实验、猜想、证明等数学活动过程,发展合情推理能力和初步的演绎推理能力,能有条理地、清晰地阐述自己的观点.
