企业会计信息化建设研究

在科技不断发展进步的今天,计算机科学技术充斥着人们的周围,给人们的生活带来了深刻的影响。新的经济发展模式改变了社会经济的主要结构。而会计的信息化在当前社会的发展应用算得上是信息化技术革新时代的必然产物。在原始的当代会计模式基础上,将现代信息科学技术巧妙的融合进去。在一个企业当中,信息化工程建设的程度应该说能够直接的影响到整个企业的管理水平和经济效益。因此,加快企业信息化工程建设,推进企业会计信息化是必要而紧迫的任务。本文就当前的企业会计信息化建设存在的问题进行分析并对如何进行会计信息化建设给出相应的对策。     

Equivalent Bar Conceptions for Computer Analysis of Pantographic Foldable Structures

An equivalent bar conception is firstly developed for the computer analysis of pantographic foldable structures. The uniplet of two three-node beam elements is assumed as a six-bar assembly with respect to least norm least square solution for the elastic strain energy equality. The equilibrium equation is developed for the equivalent models, and the internal forces formulated sequently for backup calculation. This procedure is proved practical for some engineering, and some interesting concepts proposed. Finally, three numerical tests are presented.     

空间网格结构的自动成形

依据形式代数理论，用ＦＯＲＴＲＡＮ语言编制了实用程序，使外形比较复杂的球面网壳、椭球形网壳，双曲抛物面形及筒壳等形式的网格结构能够利用计算机自动成形，避免了以往冗长，单调且易于出错的结构成形工作，与计算机辅助图形相结合，既直观又便于修改和检查，通过工程实例为说明形式代数和空间网格结构自动成形中的优越性和很强的实用性。     

企业会计内部控制的对策研究

随着国内经济的快速发展,由于企业内部管理制度的不科学,导致很多企业经济发展不景气。内部会计管理是企业管理系统中最关键的部分,因此内部会计控制受到越来越多的企业关注,并且在企业内部设立了内部会计控制体系。本文主要探讨企业会计内部控制的现状及问题,再研究针对其的对策。     

Quasi-static Deployment Simulation for Deployable Space Truss Structures

IntroductionDeployable space trusses have been used wide-ly in the past space missions,and attract increas-ingly the interests of researchers. The essentialcharacteristic is that the geometric configurationtransformation must meetthe limits of the payloadmodule during launch phase and primary require-ments of space mission in orbit.This poses a greatchallenge to numerical simulation.　　 In this paper,Cartesian coordinates of the ide-alized truss nodes are assumed as variables,a newmethod is …     

GEOMETRICALLY NONLINEAR FE FORMULATIONS FOR THE MACRO-ELEMENT UNIPLET OF FOLDABLE STRUCTURES

Introduction　　 Pantographic foldable structure works on theprinciple of a pantograph[1,2 ] . A structure of thistype may be referred to as“pantograph structure”,or simply“p- structure”. The basic unit for the p-structure is a componentso- called duplet[3 ] ,orpan-tograph unit[4] ,Scissor- Like Element ( SLE) [5] ,asshown in Fig.1 .A pantograph unitconsists of twocoplanar straightbars called uniplet,which are ca-pable of rotating about the intermediate pivot,re-ferred to as a scissor h…     

NEW WIND-INDUCED RESPONSES ANALYSIS METHOD OF SPATIAL STRUCTURES IN FREQUENCY DOMAIN WITH MODE COMPENSATION

IntroductionIn response to the demand for architecture anduse function,the span of stadiums or gymnasiumsis enlarging,which inevitably tends to involvelight- weigh roofs,such as membrane.Thesestructures with long natural periods is sensitive towind vibrations,therefore the effects of windloads,especially of dynamic wind loads,are be-coming significant at their design stage.It isknown that these types of structures are apt tohave many natural frequencies in a narrow frequen-cy range.This fact d…
