课后学习调查结果显示两组学生在英语学习方面的努力程度也相似。实验后的水平测试结果表明系统的听写练习有助于提高学生的英语听力水平和听写能力。

And also, it designs the procedure of codec test and sampling algorithm of ASSR signals.

最后对本课题设计的基于DSP的嵌入式ASSR听力检测仪进行模拟测试。

Ministry of Health has announced that ASSR system is reference for threshold estimation of artificial cochlea and newborn auditory screening.

我国卫生部已经将ASSR检测作为人工耳蜗听阈检测和新生儿听力筛查的参考设备。

Methods Tb-ABR and ASSR were performed on 10 normal hearing adults (20 ears); the response thresholds at 0.5,1,2 and 4 kHz were recorded for analysis.

方法对10名(20耳)听力正常青年人进行短纯音ABR和ASSR反应阈测试，分别记录0.5、1、2和4kHz的反应阈，比较这两种不同测试方法所得反应阈的特点及相关性。

The ASSR response thresholds at 0.5,1,2,4kHz of children with ZKS were significantly higher than those of...

结论联合应用ABR和ASSR，可以为定量定性的评估ZKS患儿听力损失状况提供依据。

So far, there is no ASSR system designed by our country, and all the ASSR systems are imported from abroad, which are expensive, and not convenient for spread. In addition, their hardware systems are too complex to repair and adjust. Hence, this paper designs an embedded ASSR system based on DSP in order to fill the gaps in this area.

目前我国还没有自主研发的多频稳态测试仪，都是从国外进口，价格昂贵，不便于推广，而且硬件电路复杂，不易维修和调试，因此本课题设计了基于DSP的嵌入式ASSR听力检测仪，能够填补国内在这方面的空白。

Methods 103 ears (67 patients) with hearing loss of different degrees were rested with ASSR and pure tone audiometry, the correlations and differences between the thresholds of ASSR and pure tone audiometry at 0.5, 1, 2 and 4 kHz were analyzed.

对67例（l03耳）不同听力损失耳分别行ASSR与纯音测听检查，比较ASSR分别在0.5、1、2、4kHz频率处的反应阈值与纯音听阈的相关性及差值。

The difference between thresholds of multi-channel ASSR and pure tone vas less than 15 dB in 71.3% of measurements; less than 20 dB in 83.1%.

多频稳定状态听性诱发反应，为临床上听障鉴定，有力且方便的客观性电生理听力检查。

Multiple Frequency Auditory Steady-State Response is a new objective audiometry which has been developed in recent years. It has good frequency-specific and maximum high output intensity, and is not likely to be affected by sleeping state or anesthesia medicine. Therefore, the clinic value of ASSR is promising.

多频稳态诱发反应(Multiple Frequency Auditory Steady-State Response，ASSR)是近年来才发展起来的一种新的客观听力检测技术，具有客观性，频率特异性好，最大输出强度高，不受睡眠和镇静药物的影响，而且检测速度快等优点，因此具有很高的临床应用价值。

As a relatively new technique in our clinical battery, auditory steady state responses or ASSR may now provide estimates of hearing in young infants in a shorter duration at discrete octave frequencies.

而多频稳态诱发电位作为一种新的测试手段开始得到关注，将给我们提供一种新的测试婴幼儿频率相关听力的快速技术。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
