sensitivity threshold

There were no statistical significant in the pacing threshold, sensitivity and lead impedance in two groups ( all P> 0.05).

两组起搏电压、感知、阻抗差异无显著性（P值均>0.05）。

Basing on theory of noise it is obtained detection equation of neutron streak image tube, from which minimal detectable neutron yield threshold of neutron pulse is induced. Also the influence of sensitivity of recording system on the detection threshold is discussed.

本文从噪音理论出发导出了中子扫描变象管的探测方程，从而求得了中子扫描变象管可探测的最小脉冲中子产额，而且讨论了记录系统灵敏度对探测阈的影响。

To systematically define the sensitivity and repeatability of heat pain threshold, using the Medoc TSA-2001 device.

目的:研究应用medocTSA-2001测定热痛阈的可信度和灵敏度.

For level VII ( nodes located in tracheoesophageal groove), minimal diameter ≥ 5 mm was used as diagnostic threshold of CT, the sensitivity was 69.23%, specificity was 100%.

以淋巴结最小径≥5mm为气管食管沟区转移淋巴结的CT诊断阈，敏感性69.23%，特异性100%。

If regarded 0.5ng/ml as positive threshold, the sensitivity of PCT in serious infection group was 91.18% and specificity was 57.50%;

以0.5ng/ml为阳性阈值，在重症感染时PCT的敏感度为91.18%、特异性为57.50%；

When PS ≥ 25 ml/ ( 100 mg · min) was set as a diagnostic threshold, the sensitivity, specificity, positive predict values and negative predict values was 68%, 67%, 85%, and 42%, respectively.

若以PS≥25ml/（100mg·min）为恶性肿瘤诊断域值，灵敏度68%，特异度67%，阳性预测值85%，阴性预测值42%。

Different threshold sensitivity can lead to different results.

由于阈值灵敏度设定不同，探伤结果不一样。

In contrast to conventional JND ( Just Noticeable Difference) threshold model, JPW describing minimum perceptual sensitivity weighting to noise changes, is fitter for nonadditive watermarking.

与传统的仅可见视差（JND）阈值模型相比，JPW刻画了对噪声变化的最小感知权重，它更适合于非添加型水印。

The establishment of central threshold base speeds up the judgment and determination of threshold and the sensitivity of judgment threshold is improved by floating threshold, thus enhances the recognition ratio of the system.

建立中心阈值库以加快判别阈值的确定，用浮动阈值提高判别阈值的机敏度，提高系统的识别率。

Results The macular threshold sensitivity changed rarely, but the central 30 degrees mean threshold sensitivity declined.

结果黄斑阈值敏感度治疗前后无明显差别，中心30°视野平均阈值敏感度下降。
