For accurately identifying the distribution charac-teristic of Gaussian-like noises in unmanned aerial vehicle(UAV)state estimation,this paper proposes a non-parametric scheme based on curve similarity *** the framework of the pro-posed scheme,a Parzen window(kernel density estimation,KDE)method on sliding window technology is applied for roughly esti-mating the sample probability density,a precise data probability density function(PDF)model is constructed with the least square method on K-fold cross validation,and the testing result based on evaluation method is obtained based on some data characteristic analyses of curve shape,abruptness and *** com-parison simulations with classical methods and UAV flight exper-iment shows that the proposed scheme has higher recognition accuracy than classical methods for some kinds of Gaussian-like data,which provides better reference for the design of Kalman filter(KF)in complex water environment.

在地震波场数值模拟过程中,人工截断边界会产生数值反射而影响地震波场模拟的精度.应用PML(Perfectly Matched Layer)吸收边界条件是消除人工边界反射的有效手段,但是该方法计算量较大,实现较为复杂,且在某些各向异性介质中不稳定.EAL(Effective Absorbing Layer)边界条件是通过简化PML吸收边界条件的阻尼项推导出来的一种吸收边界条件.EAL的吸收项作用于波动方程的时间导数项,故EAL边界条件具有计算量小且利于并行实现的特点.应用EAL边界条件能够在保证全波形反演和逆时偏移精度的前提下,提升计算效率并降低内存消耗.本文对EAL边界条件进行两点改进:(1)引入减速阻尼项;(2)采用高斯型空间加权函数构建阻尼项.正演模拟结果表明,改进的EAL边界条件在不增加计算量和内存消耗的同时,有效提升了EAL边界条件的吸收效果且适用于复杂介质和各向异性介质.特别地,相比于PML吸收边界条件,EAL边界条件在各向异性模型中表现出良好的稳定性.

清代公文汇编产生的公文集类文献,为文集视角下的公文分类实践及其分类观念研究提供了重要契机。清人的公文分类呈现出“归类趋简”和“析体趋繁”并存不悖的演进态势,不仅在归类实践中通过对“公牍”类目的“打捞”,弥补了文章总集在文学质素本位下对公牍文的有意过滤,强化了公文事功属性的本体认知,还结合清代公文体系的时代新变,创造出近十种单体公文内部的分类标准,体现出析体活动的精细化程度。清人的公文分类具有分类标准的多元化、层次架构的多级化、时代质素的多样化等多方面特征,彰显出时人公文观念的自觉和成熟。

作为目前网络环境中公民交流表达的重要方式,表情语言对网络空间治理的形式与方式提出了新的挑战。“语言与意义的社会建构理论”将传统形式语言学的二元关系发展至了“语言、人和世界”的三元关系,从这一范式出发并结合信息传播载体发展的历史脉络,能够准确理解、分析表情语言对网络空间的具体影响。首先,就“语言与世界”的关系而言,表情语言分别基于网络社交媒体的平台搭建实现了网络空间中权力中心的转换。其次,就“人与语言”的关系而言,语言使用者从单维扩至多维的信息质量需求,促成了语言符码媒介意象性的延展。最后,就“人与世界”的关系而言,表情语言共同体意图摆脱主流叙事这一文化诱因,使得表情语言培育了新的网络话事生态。面对上述网络空间治理的新势态,应当通过表情语言,搭建符合治理者视角的表情语言体系;认可表情语言,丰富网络空间的信息传播载体形式;守正表情语言,维持网络空间治理的表情运用底线。
