刺激阈

Obserdose of noradrenaline bitartrate or KCl: Sub-maximal constriction of thoracic aorta was induced by 0.1 mmol/L noradrenaline bitartrate or W60 mmol/L KCl, and when constriction curve became stable, DL or nimodipine of different dosage was added.

记录电刺激心室乳头肌时收缩的幅度变化：1次/s，波宽3 ms，阈电压的120％强度电刺激以引发心室乳头肌同步收缩活动，待收缩曲线平稳后，分别用累加法加入二氢石蒜碱或尼莫地平。

从时空两域阐述神经纤维对不同时变磁场诱导作用下的阈下响应行为，对磁刺激仪中刺激线圈的刺激电流的选择和线圈尺寸的设计都具有指导意义。

Results The patients were predominently female teenagers with a history of gradual onset of bilateral hearing loss, pure tone audiometry revealed symmetric ascending audiograms with moderate hearing loss at frequencies below 1 kHz, but relatively normal hearing at 2 kHz and above. Speech reception thresholds were between 40 to 85 dB HL, discrimination score was from 29% to 68%. Stapedial reflex, auditory brainstem response and compound action potentials were absent or threshold elevated disproportionately to the pure tone threshold. All of the patients had normal cochlear microphonics and robust spontaneously and transiently evoked otoacoustic emissions, the TEOAE showed no contralateral suppression effects as seen in normal subjects.

结果 该病多在青春期后起病，女性较多发，表现为渐进性双耳对称性听力下降，纯音听力以低频损失为主，语言接受阈升高，分辨率下降，镫骨肌反射及ABR引不出或阈值明显升高与纯音听力不成比例，耳蜗微音器电位正常，听神经动作电位引不出，耳声发射波幅高、时程长且不为对侧声刺激所抑制。

The threshold and latency of CDM-CEP was 85±3.54 dB and 6.59±0.41s in normal control group,90±5.0 dB and 6.68±0.31 s in artificial perilymph group,but could not induce CDM-CEP at 120dB level still in neomycin group.

在短声刺激下，正常大鼠引出CDM-CEP的阈值为85±3.54 dB，阈值时的潜伏期为6.59±0.41s；新霉素组大鼠120dB仍无法引出CDM-CEP；人工外淋巴液组大鼠引出CDM-CEP的阈值为90±5.0dB，阀值时的潜伏期为6.68±0.31s。

Giving the muscle a stimulus which is higher than the threshold stimulus, a single twich curve, which is made of latent period, shortening period and relaxation period, can be observed.

当给予肌肉标本一个高于阈刺激的单刺激时，可以在计算机中观察到由潜伏期、收缩期和舒张期组成的单收缩曲线。

Methods The clinical application of 25 normal subjects were stimulated at 1Hz at stimulus intensities corresponding to threshold, recording from the abductor pollicis brevis muscle belly.

25例健康个体，于正中神经腕点处刺激，在拇短展肌肌腹内接收，刺激频率为1 Hz，刺激强度为阈强度上下。

Objective To investigate whether there are any differences existing in auditory steady state responses to single or simultaneously multiple sinusoidally modulated tone stimuli.

目的 研究正常听力青年人多频稳态诱发电位单频刺激与多频刺激所记录到的反应阈，比较在4个测试频率得到的两种反应阈是否有差异。

Whether they are presented subliminally or supraliminally, fearful faces are processed at an early stage in thestream of visual processing, giving rise to enhanced activation of right extrastriate temporal cortex as early as170 ms post-stimulus onset.

不管面孔的呈现是感觉阈值下的还是阈值上的，在视觉信息流中惊恐面孔在较早阶段就得到了处理，这才使得右侧颞区的外纹状皮层在刺激后170ms就出现了活动的增强。

With objective detection threshold timeas the prime exposure time and figues (Ara-bic figures) and numerals in Chinese andGermans as stimili,we compared the primingeffects of Chinese and German under patter-ned masking.

本文采用客观觉察阈值作为启动刺激呈现时间、以数字和数词(以中、德两种文字写出的数词)为刺激比较研究了在掩蔽刺激条件下中国与德国被试的启动效应。

Differential threshold: The minimal difference that can be detected between two similar stimuli it called the differential threshold, or the just noticeable difference.

差别感受阈限：刚刚能够察觉的刺激物的最小差别量被称为差别感觉阈限，或最小差别感受阈限。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
