In order to distribute traffic flow guidance information board(TFGIB) in urban properly,the optimization model of configuration of TFGIB was put forward based on the restriction of improving guidance coverage rate and reducing guidance repeat rate.
为合理进行城市交通流诱导,提出了一种基于提高诱导覆盖率和减小诱导重复率双重约束下的信息板配置优化方法。
Since the repeat-induced point mutation (RIP), a gene silencing mechanisms in Neurospora crassa, was discovered in 1986, methylation induced premeiotically (MIP), quelling, and meiotic silencing by unpaired DNA (MSUD) had been found in fungi one after another.
自1986年在粗糙脉孢菌(Neurospora crassa)中首次发现真菌所特有的真核生物基因沉默机制重复序列诱导的点突变(repeat-induced point mutation,RIP)以来,在真菌中又相继发现了减数分裂前诱导的甲基化(methylation induced premeiotically,MIP)、压制(quelling)和非配对DNA介导的减数分裂沉默(meiotic silencing by unpaired DNA,MSUD)等RNA沉默现象。
Objectives To monitor depth by combination of bispectral index(BIS),95% Spectral edge frequency(SEF) and heart rate variability(HRV) following induction of droperidol-fentanyl,etomidate or co-induction of midazolam at same time and investigate the effect of endotracheal intubation on BIS,95% SEF of electroencephalogram and HRV.
目的 联合应用双频谱指数 (BIS)和心率变异性 (HRV)监测氟芬合剂、依托咪酯及其加用咪唑安定复合诱导时的麻醉深度 ,观察诱导后气管插管刺激对BIS和HRV的影响。
