自发的

The present work was carried out to investigate the effect of electrical stimulation of the caudate nucleus on the electrical activity of the neurons of the cingulate gyrus.

实验在52只家兔上进行。实验结果表明：尾核头部的刺激可以影响44％的扣带回前部神经元的自发放电活动，绝大部分表现为自发放电的抑制。

The present results suggest that (1) NA is not mainly concerned with spontaneous discharges of chemoreceptor sensitive to hypoxia, but does elicit an increase in spontaneous discharges, and (2) the increase of chemosensory unit discharges produced by hypoxia can be inhibited by yohimbine.

结果提示：(1)NA不是维持颈动脉体对缺氧敏感的化学感受纤维自发放电活动的主要因素，但给予NA能增加此类纤维自发放电的频率；(2)在低氧过程中，给予#alpha#_(2)受体拮抗剂育亨宾，可减弱这类纤维对缺氧反应的程度。

This study demonstrated that KA administration in a convulsant dose could result in spontaneous recurrent seizures and permanent disturbances of behavior and cognition in old rats (P25、P60) which brains were in mature. However temporal and reversible effects occurred in rat pups (P5、P15) in immature brain.

一次给予惊厥剂量的KA可诱发脑发育成熟大鼠（P25、P60）出现自发癫痫发作，但在脑发育未成熟大鼠（P5、P15）中未见有自发癫痫发作；KA致痫对脑发育成熟大鼠造成的认知行为异常持久而不可逆，但对脑发育未成熟幼鼠认知行为的影响则持续时间短而可逆。

Studies on statistical properties of spontaneous spike trains of single auditory nerve have shown that the distributing patterns of interval in spike trains represent Poisson distribution. Since Poisson distribution is one of the simplest stochastic processes, previous studies on spontaneous spike trains of single auditory nerve were performed primarily by assuming them as stochastic processes. Recently, further studies on nonlinear dynamic system show that we have not enough evidence to demonstrate the process, whose distribution of probability density is exponential, is Poisson process.

中文题名豚鼠听神经单纤维放电序列的非线性特性分析副题名外文题名 Analysis on nonlinear properties in spike trains of single auditory nerve fiber in guinea pig 论文作者林龙年导师孙心德教授学科专业生理学研究领域\研究方向听觉神经生物学学位级别博士学位授予单位华东师范大学学位授予日期2001 论文页码总数91页关键词听神经听觉神经生理豚鼠馆藏号BSLW /2001 /Q42 /41 对听神经单纤维自发放电序列的统计特性研究表明，听神经单纤维放电间隔呈泊松分布，而泊松过程是最简单的随机过程之一，因此以往的研究主要将听神经单纤维自发放电序列作为随机过程来处理。

Additionally, the spontaneous decomposition from (220) surfaces to {112} facets is confirmed and irrelated to the substrates adopted. The effects of Ga content on lattice vibration modes are discussed in the quaternary 〓 films firstly.

系统地研究了不同硒化温度和退火时间以及Ga含量x等因素对薄膜性能的影响，证实了（220）自发分解现象，而且这种自发分解现象并不受衬底的影响。

Antibody to PE could block this function. In vivo PE could enhance murine splenocyte proliferation but not level of IL-2 production.

PE在体内能使小鼠脾淋巴细胞自发淋转率增高，对ConA刺激的增殖反应增强，但对淋巴细胞自发分泌IL-2和ConA诱导IL-2的产生水平无影响。

Results Intravenous 5-HT caused obvious exciting effect on spontaneous afferent discharge of subdiaphragmatic vagus nerve.

结论5-HT可能是作用于与迷走传入相关的5-HT3受体兴奋了膈下迷走传入神经自发放电；促胰液素可以增强5-HT对迷走神经传入自发放电的兴奋作用。

A spontaneous deposition approach was developed to form a Pt ultrathin overlayer onto a Ru nanoparticle film (simplified hereafter as Ru/Pt film) in which the freshly electroreduced Ru film wereas subsequently immersed in a deaerated H2PtCl6 solution without potential control.

采用自发沉积法在Ru膜上生成超薄Pt层，即在开路状态下将电化学还原后的Ru膜浸于除去氧的H2PtCl6溶液中进行自发沉积。

The rescaled range statistical analysis (R/S analysis) has been initiated by Harold Edwin Hurst to describe the long-term dependence of water levels in rivers and reservoirs.

应用这种分析法对听神经自发放电时间序列作了进一步的考察，分别计算了31个听神经自发放电时间序列的赫斯特指数，并根据赫斯特指数计算出了相应的分维值。

It was also found base transversion had a extremely high ocurrence frequency in the single base substitution mutants when the plasmid was replicated in FL-FEN-1〓 cell or MNNG pretreated FL-FEN-1〓 cell, while in all mutants with multiple base substitution there were at least one transversion mutation taken place.

分析还发现，在FL-FEN-1〓细胞自发突变和非定标突变含有单碱基替换突变的突变子中，碱基颠换的发生率极高，而在FL-FEN-1〓细胞自发突变和非定标突变的多碱基替换突变子中，每个突变子均至少含有一个碱基颠换突变。
