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。

So called reservoir is physical or mathematical; for a physical system, the mathematical model is a system of partial differential equations with related initial and boundary value conditions, it can describe important physical process occurring in the system, for example, the process occurring in reservoir, which mainly concludes flow of fluids and transportation of mass, gravity、 viscosity、compressibility have effect to it; differential equations describing this process are obtained by combining Darcy law of every phase and its mass equilibrium in differential form.
这种模型是物理的或数学的;一个物理系统的数学模型,是偏微分方程组和适当的一组初、边值条件的总体,它能够描述在系统中发生的重要的物理过程,比如在油藏中发生的过程,主要是流体的流动和质量的转移,重力、粘滞力、压缩性等在流体流动过程中都是起作用的;描述这个过程的微分方程是由将各相达西定律和各该相的微分形式的物质守恒相结合而得到的。

Combined with additional sequences of 20 bivalves and 6 gastropods downloaded from NCBI (National Center of Biological Institution), molecular phylogenetic trees were constructed using 4 Polyplacophora species as outgroup. The result resolved by maximum-parsimony, maximum-likelihood and Bayes-induce methods were in congruent with each other, which indicated that all bivalves formed a monophyletic group clustering with its sister-group, Gastropod.
结果显示:所有双壳纲的种类构成了单系发生的进化枝,与其姐妹群腹足纲聚在一起;双壳纲可以分为异齿亚纲和翼形亚纲两大类群,异齿亚纲是单系发生,翼形亚纲的系统发生关系则随方法的不同有所区别,牡蛎科的位置是造成此差异的主要因素。
