Little is known about ocean viromes and the ecological drivers of the evolution of aquatic RNA viruses.This study employed a meta-transcriptomic approach to characterize the viromes of 58 marine invertebrate species across three seas.This revealed the presence of 315 newly identified RNA viruses in nine viral families or orders(Durnavirales,Totiviridae,Bunyavirales,Han-taviridae,Picornavirales,Flaviviridae,Hepelivirales,Solemoviridae,and Tombusviridae),with most of them being sufficiently divergent to the already documented viruses.Notably,this study revealed three marine invertebrate hantaviruses that are rooted to vertebrate hantaviruses,further supporting that hantaviruses may have a marine origin.We have also found evidence for possible host sharing and switch events during virus evolution.Overall,we have revealed the hidden diversity of marine invertebrate RNA viruses.

由于许多选矿厂,在分选矿产资源时,采用不恰当的生产工艺,导致矿石中许多有用组分不能得到回收,成为矿山的尾矿.为使尾矿中的有价成分实现合理利用,本文以典型矿山的含铁尾矿为研究对象,使用悬振锥面选矿机,对铁元素含量为17.81％的尾矿试样进行分选处理.优化选矿工艺参数并进行选矿试验后,从该尾矿中回收了品位为61.75％的铁精矿,铁元素回收率为60.31％.
随着经济全球化的不断发展,我国的经济发展水平也得到了一定的提升,经济的发展离不开科技的创新.如今,科技已经进入人们的生活,广泛地应用于各行各业,尤其是旅游业,由于人们生活需求的不断增加,旅游成为人们生活质量提高的一种表现.近年来由于科技的发展,一种新型的旅游行业——智慧旅游,走入了人们的生活,智慧旅游使游客的旅行变得更加方便快捷,使旅游行业得到突飞猛进的发展.但由于智慧旅游刚刚兴起,当下还存在一些不足,因此需要不断地发展与完善.本文通过对智慧旅游在旅游企业管理中的应用进行分析与总结,提出有关发展建议,以提
财务部门作为资金流和数据流的中心,承载着企业资金管理、成本控制、决策分析等管理职能.在大数据的时代背景之下,云计算、区块链、人工智能等前沿技术已经颠覆了传统的管理思维和管理手段,像一只无形的手,推动行业自我革命.从数字化到智能化再到智慧化,财务管理部门应当主动融入这个大数据时代,适应数字经济发展趋势,针对转型发展中的瓶颈问题,开展自我革命,推动财务会计向管理会计转型.本文主要针对大数据背景下企业财务会计向管理会计的转型展开分析,挖掘企业转型过程中存在的问题,并提出合理建议,为现代企业财务管理发展之路提供借
