So we think that DML can be used to treat presbycusis by clearing free radicals. We will continue our search on free radicals.

因此我们可以推测碟脉灵也具有这一作用，可以通过清除自由基来治疗老年性聋，我们将在这一方面做进一步的研究。

Objective To determine whether or not the mtDNA4977 deletions contribute to human aging and involve in the development of presbycusis.

Most adults are unable to hear frequencies above 15Khz due to age-related hearling loss known as presbycusis.

大多数成年人都无法听到的频率15khz以上因年龄相关hearling损失称为聋。

These findings indicated that mtDNA4977deletions in human contribute to presbycusis, as well as aging.

mtDNA4977缺失的发生与老化有关；内耳和蜗核组织中mtDNA4977缺失与老年聋的发生有关。

The presence of systemic diseases as hypertension, coronary heart disease and diabetes mellitus is relevant to higher rate of presbycusis.

全身老年性疾病如高血压，冠性病，糖尿病可增加老年性聋的发生率。

However, the incidence of carrying mtDNA4977 deletions in heart and liver were no significant difference between presbycusis patients and the control group.

老年聋患者颞骨切片和蜗核组织中mtDNA4977缺失的发生率明显高于老年听力正常组，其差异具有显著性意义（χ2检验，P＜0.05）；而与听觉无关的心肌和肝脏组织中mtDNA4977缺失发生率在两组之间差异无显著性。

15Khz . Most adults are unable to hear frequencies above 15Khz due to age-related hearling loss known as presbycusis.

大多数成年人都无法听到的频率15khz以上因年龄相关hearling损失称为聋。

Age-related hearing loss also known as 'presbycusis' begins with loss of certain speech sounds like 'S','F' and 'T'.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
