桥梁与隧道的近接施工是目前最常见的近接工程之一,为了研究桥梁桩基与隧道之间近距离施工所产生的影响,采用ANSYS模拟计算桩基近接隧道施工过程,通过桥梁桩基修建造成既有隧道位移和应力增量的变化,对桥梁桩基近接既有隧道进行影响分区划分。结果表明:依据桥梁桩基与既有隧道的距离,可划分为强影响区、弱影响区和无影响区,3个区域的两个分区界限分别为1. 0倍和2. 0～2. 5倍洞径;桥梁桩基越长对隧道影响越大,一旦桩基伸入既有隧道潜在滑移破裂面以下,桩基继续加长对隧道的影响可忽略不计。用FLAC3D有限差分软件,对即将修建的宜(宾)毕(节)高速公路斑竹林大桥上跨成贵铁路青岗脚隧道工程进行三维计算,其结果验证了结论的正确性,并给出评估结果和合理建议。

The objective evaluation of speech quality can replace expensive manual scoring,but current objective indicators usually need pure reference speech,which is difficult to obtain in many practical acoustic systems.A non-intrusive speech quality evaluation algorithm combining auxiliary target learning and a convolutional recurrent network(CRN)is *** frequency cepstral coefficients(BFCCs),which are based on human-like auditory filters,are used as the input of the CRN network to effectively reduce the network ***,frame-level features are extracted by a convolutional neural network(CNN)from ***,long-term time dependence and sequence features are modeled by the bidirectional long shortterm memory(BiLSTM)networks in frame-level ***,a self-attention mechanism is introduced into the CRN,thereby adaptively extracting useful information from frame-level features,which is then integrated into the characteristics of the sentence level and mapped into the final objective *** addition,a multi-task training strategy is adopted,and voice activity detection(VAD)is introduced as an auxiliary learning target to improve the performance of the *** in public databases show that compared with other non-intrusive algorithms,the proposed algorithm has a better correlation with the mean opinion score(MOS).Moreover,it has a small parameter size and good generalization ability for the distorted speech database with MOS released by ITU-T P.808,which is close to the accuracy of the perceptual evaluation of speech quality(PESQ).

γ-氨基丁酸(Gamma-aminobutyricacid,GABA)是中枢神经系统中非常重要的一种抑制性神经递质,和受体结合后介导抑制性神经传导作用.通过侧脑室注射崁烯氯噻嗪(CTZ)诱发癫痫行为发作,并观察在慢性期内出现自发性癫痫发生,建立慢性癫痫动物模型.采用Nissl染色和免疫组化染色方法对海马CA1区和CA3区神经元数目和GABA表达情况进行了研究,发现CTZ慢性癫痫模型中海马CA1区和CA3区神经元数目无明显变化,但是神经元胞体和树突中GABA表达减少,说明抑制性神经元中GABA减少是CTZ慢性癫痫反复性癫痫行为发作的重要原因之一.

We report the successful preparation of a purely honeycomb,graphene-like borophene,by using an Al(11 1) surface as the substrate and molecular beam epitaxy(MBE) growth in ultrahigh *** tunneling microscopy(STM) images reveal perfect monolayer borophene with planar,non-buckled honeycomb lattice similar as *** calculations show that the honeycomb borophene on Al(1 1 1) is energetically ***,nearly one electron charge is transferred to each boron atom from the Al(1 1 1) substrate and stabilizes the honeycomb borophene structure,in contrast to the negligible charge transfer in case of borophene/Ag(1 1 1).The existence of honeycomb 2 D allotrope is important to the basic understanding of boron chemistry,and it also provides an ideal platform for fabricating boron-based materials with intriguing electronic properties such as Dirac states.
