您要查找的是不是:
- threshold shift test 阈限旋转试验
- The remaining hearing loss after the exposure that does not fully recover to its preexposure level is known as permanent threshold shift (PTS). 听性脑干反应则分别在噪音暴露前、暴露后、暴露后1天、暴露后2天、或暴露后7天施行。
- Aim: To observe the combined effects of four physical factors(noise, lighting, temperature and humidity) on temporary threshold shift (TTS). 目的:观察舰艇舱室环境噪声、照明、温度、湿度4种物理因素联合作用对暂时性听阈偏移的影响。
- Result: Six months later, all patients had negative Lachman and Pivot shift test. 结果:两组术后6个月比较,膝关节活动度无明显差异;
- The stress valgus test and lateral pivot shift test (PST) were negative for all the patients.No elbow pain occurred. 肘关节未发生复发性脱位,应力外翻试验阴性,肘关节外侧及后外侧轴移试验(PST)阴性,肘部无疼痛;
- NIHL can be divided into temporary threshold shift (TTS) and permanent threshold shift (PTS). The TTS can soon recover if we break away from noise exposure. 噪声性听力损失分为暂时性阈移(Temporary threshold shift,TTS)和永久性阈移(Permanent threshold shift,PTS)。
- A new arid complete concept of shift quality was developed based on the gear shift test of a car equipped with an automated manual transmission (AMT). 同时结合试验对装载自动机械式变速器的车辆进行分析,提出了新的、更加完整的换档质量评价概念,从而扩宽了传统换档质量评价的研究范围。
- Fourteen ACL reconstructions were performed at allograft patellar tendon: One patient was in the ADT I degree, 1 in the Lachman (+), 1 in the pivot shift test (+). 14例异体髌腱移植重建前交叉韧带、髌骨供区植骨患者:前抽屉试验I度1例,Lachman试验(+)1例,轴移试验(+)1例;
- In the 4th week, compared with that in animals accepting GM, ABR threshold shift was notable in animals accepting GM and L-Arg ( P < 0.05), but it was diminished in group GM and L-NMMA ( P < 0.05). 实验第 4周 ;GM加L -Arg组ABR反应阈升高明显 ;与GM组比较有统计学意义 (P<0 .;0 5 );GM加L -NMMA组ABR反应阈升高较少;与GM组比较有统计学意义 (P <0
- Method:Fifteen of young men with normal hearing were exposed to 4 kHz short-term pure tone (Level ~ 130 dB SPL) for 3 minutes to analysis the change of DPOAE in details after Temporary Threshold Shift (TTS). 方法:用 130dB SPL的 4 kHz纯音对 15例听力正常人(30耳)进行 3 min的短时暴露,造成听力暂时性阈移后,用ILO-90耳声发射仪记录、分析暂时性阈移(TTS)时DPOAE的幅值、时间序列的特征,并与纯音暴露前进行对比。
- noise induced permanent threshold shift 噪声性永久性阈移
- noise induced temporary threshold shift 噪声性暂时性阈移
- noise-induced temporary threshold shift 噪声导致暂时性听阈改普变, 噪声性暂时性阈移
- The hearing threshold shifts for humans and guinea pigs were observed after exposure for 2 hours to a 105-dBA broadband noise. 本文观察了在105dBA 的宽带噪声下暴露2h,人和脉鼠的听阈偏移。
- A simple test will show if this is real gold. 简单的试验就能证明这是否是真金。
- noise-induced permanent threshold shift 噪声导致永久性听阈改变, 噪声性永久性阈移
- Researchers found that more than 12% of the children had hearing damage known as noise-induced hearing threshold shifts, or NITS. 研究发现,超过12%25的儿童存在噪音性听力下降。
- The ABR threshold shifts in the NGF group 3 hurs,3 days,11 days,and 21 days after the blast exposure were significantly smaller than those in the NS group. 爆震后 3d NGF组 ABR反应阈恢复较生理盐水组显著快 ,2 1d后 ,NGF组 ABR已恢复正常水平 ,而生理盐水组未能恢复正常水平。
- For Poly-Si/high-k pMOSFET, a dominated hole or electron trapping depend on the magnitude of voltage bias will cause opposite effect on device s threshold shifting. 负偏压温度不稳定性实验中,不同的强迫电压可造成总陷入于高介电常数薄膜中电荷种类的不同。
- Pupils who pass the test will be promoted to the next higher grade. 小学生只要考试及格就会升到高年级。
