甲状软骨的

Although the use of traditional palpable anterior neck landmarks (hyoid bone, cricoid cartilage, thyroid cartilage, and carotid tubercle) help identify appropriate spinal levels, their reliability has not been validated in actual surgeries.

尽管使用传统的可触及的颈前面标志物（舌骨、环状软骨、甲状软骨和颈动脉结节）能帮助识别适当的脊椎水平，但他们的可靠性在实际手术中没有被验证。

A bright, round or oval glow in the midline just below the cricothyroid junction could be a reliable pattern to indicate the ETT-TL tip has passed the vocal cords.

在正中线、环状软骨甲状软骨交界处的下方的明亮、圆形或椭圆形的亮光，可视为气管内管/ TrachlightTM 组装单位的尖端已经通过声门的可靠形态。

METHODS: As a pilot study, we prospectively evaluated 30 consecutive patients who underwent anterior cervical diskectomy and fusion to assess the interobserver accuracy of palpating the mandibular angle, hyoid, carotid tubercle, and thyroid and cricoid cartilages.

作为先导研究，我们前瞩性的评估连续30例行椎间盘切除并融合术的病人，评价触摸下颌角、舌骨、颈动脉结节、甲状软骨和环状软骨时目标观察物的准确度。

Methods This sample consists of 73 male Chinese han individuals whose ages have been known. Eight positions were selected from their radiograms which have been divided into three or six grade and then set up a mathematical model to deduce age by multiple linear regression analysis.

方法对73例已知年龄的中国汉族男性甲状软骨进行软X线摄片和X线摄片，从摄片上选择8个与年龄变化关系较为密切的观察部位，每个部位又划分成3至6个等级，然后采用多元线性回归方法，建立其推算年龄的数学模型。

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。
