Results CTVE could clearly demonstrate the shape,size,and relation of the normal auditory ossicular chain.A visualization rate of malleus,incus,and incudomalleal articulation was 100%,and was 32% for the stapedial footplate.However,in only 21% could the anterior and posterior crura of stapes be distinguished.Cholesteatoma was found in 12 cases with chronic otitis media,in which CTVE demonstrated varying degrees of destruction of the auditory ossicle.In 1 case with congenital anomaly,ossicle dysplasia was seen.

结果 CTVE能清楚显示正常听骨链的形态、大小及相互关系，锤骨、砧骨及锤砧关节的显示率为100%(38/38)，镫骨底板的显示率为32%(12/38)，只有21%(8/38)可以分辨镫骨的前、后脚；18例中耳炎患者中12例胆脂瘤形成，CTVE上有不同程度的听小骨破坏。1例中耳畸形显示听骨链发育异常。

Results: The satisfactory MPR images of cochlea, bony semicircular canals, internal auditory meatus and other intratemporal structures can be obtained. The SSD images could show some important bony marks of temporal bone and spatial relationships between them clearly. On coronal plane, SSD images can vividly demonstrate the shape and spatial relationships of malleus and incus. A series images were obtained as the virtual endoscope moved from the external auditory canal to the middle ear cavity.

结果：MPR能在不同切面显示耳蜗、半规管、内耳道及面神经管垂直段等结构，显示率为100%；SSD能清晰显示颞骨重要的骨性结构，如内耳门、颈静脉孔等，冠状位切割后的SSD图像能生动地显示锤骨、砧骨的立体形态及空间关系；CTVE可模仿内窥镜从外耳向中耳移动，清晰显示骨性外耳道、鼓室内侧壁及听骨链等结构。

Auditory Brainstem Response, ABR (or Brainstem Auditory Evoked Potentials, BAEP) is a human body physiology parameter at microvolt level. First, we use the TMS320F2812 of TI company, making the signal through D/A transform and high accuracy operational amplifier, and produce the masking white noises, as well as the Tone Burst to be the stimulus. Then, the evoked EEG will be amplified and filtered. At the same time, we use the A/D of TMS320F2812 to collect and process the signals, and get the digital BAEP.

听觉脑干诱发电位(Auditory Brainstem Response，ABR)为微伏级人体生理参量，采用TI公司的DSP TMS320F2812，通过D/A与高精度运算放大器，生成听力级可调整的掩蔽白噪声与短纯音TB进行刺激，同时对诱发脑电进行放大、滤波、并使用TMS320F2812的A/D进行信号采集与处理，得到数字化的脑干诱发电信号。

We use modiolus puncture approach shown by Alder to obtain recordings of discharge signals from single auditory nerve in guinea pig, and adopt digitally controlled system, which is designed on our self to generate complex waveforms, to measure properties of basic acoustically-evoked response of single auditory nerve.

实验在23只豚鼠上进行，运用Alder的蜗轴穿刺法，记录豚鼠听神经单纤维放电，并用自行研制的计算机程控复杂模式声刺激系统，测定听神经单纤维的基本声反应特性。

Previous studies made in our lab indicated that monaural plugging during the critical period of postnatal development would reduce the special sensitivity of the auditory neurons in the contrary auditory cortex of the plugged ear, with the decrease of NMDA receptor density and its subunits expression in the relative cortex of the adult animal.

本实验室以往的研究表明，在生后发育"关键期"内对大鼠施行单耳堵塞，成年后测定显示，堵塞耳对侧中枢神经元听反应敏感性降低，并伴随相关脑区NMDA受体密度的下降，NMDA受体亚单位mRNA表达减弱。

So it is an effective evaluation method of auditory threshold that has frequency specialty for auditory obstacle.

由于40Hi AERP目前在国内的应用较少，特别是在法医学鉴定中如何应用40Hi AEgn客观评价听觉功能障碍还有待进一步研究。

Frequency and spatial coding of auditory information in auditory cortex and inferior colliculus was studied in this research.

本报告以蝙蝠为实验动物，对听皮层和中脑下丘对听觉信息的频率和空间的编码进行了研究。

Results MRI appearances of acoustic neuromas were:（1）The turmor's growth round the internal auditory canal,the Ⅶ,Ⅷ nerves affected side were thickened than that of opposite side.There was no marked demarcation between the main bodies of the tumors and the affected nerves.The connection between tumors and affected nerves could be showed at contrast enhanced imaging.（2）The tumors were of hypo or isohypo intensity on T1 weighted images and hyper or iso hyper intensity on T2 weighted images.（3）After Gd DTPA administration the tumors were homogeneously or inhomogeneously or circularly enhanced.（4）The margins of the tumors were smooth and well delineated.（5）The affected internal auditory canal usually became shorter in depth and larger in posterior anterior diameter.（6）MRI appearances of micro acoustic neuromas were that the affected Ⅶ,Ⅷ nerves were normal in size or nodularly thickened and the tumor reveaed nodular or point enhancement at contrast enhanced MRI.

结果 听神经瘤的MRI表现主要为：（1）肿瘤以内听道为中心生长，第Ⅶ、Ⅷ神经束较对侧增粗，与肿瘤主体多无明确分界，增强后可见两者相连，颇为特征；（2）肿瘤在T1加权图像上呈低信号、略低信号或低等混合信号，T2加权呈高信号或高等混合信号；（3）注射Gd DTPA后肿瘤呈均匀、不均匀或环状强化；（4）肿瘤边界清晰，边缘光整；（5）绝大多数肿瘤患侧内听道前后径扩大，深径缩短；（6）微小听神经瘤的MRI表现为第Ⅶ、Ⅷ神经束正常或局部结状增粗，造影后呈结节状或点状增强。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
