All ofusers of the system are separated into eight soles, and each sole has different privileges. Users are assigned and privileged by DBA. Any user must pass the identity validation before using the system. IP banding is used to increase the security of the system on hardware, which means the DBA must usethe IP set by program. Leaders can function as sanctifier of important information when using the system.

根据用户的职能，把系统用户分成八个角色，每个角色根据各自的职能拥有不同的权限，用户由系统管理员分配和授予角色，必须首先经过身份验证才能进入系统；在硬件方面实行IP绑定，由服务器程序设定了行使系统管理员职能必须使用规定的IP地址；对重要信息的管理必须由主管领导审批，为此设计了各级领导的审批功能。

So we designed a adaptive synchronizing controller based on hereinbefore hardware environment: first a small magnitude reference signal r is outputted to system through the signal card (to ensure that the vibrating system works in a linear state), and this signal is sent to the moving coil of vibrator through the power amplifier, so vibration is produced through electromagnetic induction. Secondly the vibration signal can feedback to the data acquiring card in the servo system through the acceleration sensor on the Vibroseis reactor M〓 and the base-plate M〓, then the computer can get the current vibrating state y〓 of the coil of vibrator according to the feedback information from the data acquiring card, and give a real time comparing between the current state y〓 and the reference output y〓 of the set-in reference model with current reference input being r , then regulates the correlative controlling parameters according to the error e〓=y〓-y〓 till y〓→y〓, finally normal signal sweeping begins with a certain phase fixed. Meanwhile a synchronization signal for seismic signal record is sent to seismograph from synchronization signal outputting component in the Vibroseis system to perform the controlling process of synchronization of sweeping phases.

为此，我们基于以上的硬件环境设计了一个自适应同步控制器：首先通过信号发生卡对系统输出小幅度的参考信号r(从而保证振动系统工作处于线性状态)，信号通过前置放大器、功率放大器等送到激震器动圈，并通过电磁感应产生振动，振动信号通过可控震源激震器反应块M〓和基板M〓上的加速度传感器反馈给伺服系统中的数据采集卡，工控计算机根据采集卡的反馈信息，获取当前激震器动圈的振动状态y〓，并实时地将该状态与内置的参考模型在当前参考输入r下的参考输出y〓进行辨识，再将两者输出误差e〓＝y〓-y〓对系统的有关控制参数进行调整，直至y〓→y〓，最后在经过某一固定的相位后，开始信号的正常扫描过程，与此同时，由可控震源系统的同步信号输出部件向地震仪送出一地震信号记录同步信号，进而完成扫描相位同步控制过程。

For solving the Y2K problem, many large-scale overseas or home enterprises used ERP system to replace the old system in their enterprise. Many enterprises even used it as the foundation of electronic enterprise ,and integrated other information systems into it. However the organizational performance is not necessarily good. Some scholars think the performance of ERP will be influenced by the time length after ERP go-live and the different performance targets. Ross even thought the performance of ERP will assume a "V" path when improvementing an ERP,and get continuate improvement. Therefore this research is for discussing whether the ERP system can improve organizational performance. It used the different performance targets to evaluate the long-term organizational performance that ERP system brought.

摘要 在千禧年Y2K的推波助澜下，国内外许多大型企业纷纷使用企业资源规划(Enterprise Resource Planning，ERP)系统来取代企业内部的旧系统，甚至许多企业将ERP系统当作企业电子化的基础，进一步整合其他的资讯系统，但是不一定都能有好的绩效结果，因此有学者认为ERP绩效会受到系统上线后的时间长短或效益衡量标的的影响而改变，ROSS学者甚至认为ERP系统的绩效甚至会在上线后呈现V字型的改善路径，并且会呈现持续改善的状况。
