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。

The resulting strain, designated YES2MTM1, was transformed with a yeast genomic library. Transformants lost the plasmid overexpressing MTM1 after 5-FOA treatment. Yeast strains able to grow on nonfermentable carbon source with MTM1 deletion and overexpression of some DNA fragments were picked up and candidate suppressor genes were identified. Overexpression of five genes were identified to be able to rescue the growth defect on nonfermentable carbon source. The study will provide reference for MTM1 gene function and screening for suppressor of genes whose deletion result in irreversible damage.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
