中央轴

METHODS: Refractive error (cycloplegic auto-refraction with subjective refinement), central corneal thickness and axial length, intraocular pressure, and corneal hysteresis (Reichert Ocular Response Analyzer) were measured on a rural school-based cohort of children.

在以一个农村地区学校为基础的队列中，对这些儿童进行屈光不正（睫状肌麻痹性自动验光和主观优化）、中央角膜厚度、眼轴长度、眼内压和角膜滞后（Reichert眼部反应分析仪）等指标的检测。

Step 1: Center the secondary mirror on the axis of the focuser drawtube.

把副镜中央置于调焦伸缩管的中轴。

Step 3: In this, the final and most critical step, you need to tilt the main mirror to center its sweet spot in the focuser.

第3步，最后也是最关键的一步。你必须调整主镜的倾斜角度，使主镜的甜点处于调焦座的中央，光轴也要正。

When Step 3 is done, the optical axis is accurately centered in the focuser, and collimation is complete.

当完成第3步后，光轴就精确地位于调焦座中央了，大功告成。

All lenses were classified using the lens opacities classification system Ⅲ based on four categories: nuclear color, nuclear opalescence, cortical cataract and posterior subcapsular cataract. ALs were measured 20 times with an IOL Master, 5 times with an IOL Master version 4.0, and 5 and 15 times with an IOL Master version 5.0 and the results were recorded.

IOL Master 5.0版相对于传统IOL Master采用了组合信号分析技术，将多个低信噪比（signal-to-noise ratio，SNR）的单次眼轴测量结果进行叠加组合，使噪音相互抵消，而反映黄斑中央凹位置的信号被放大，从而提高了SNR。

Centrarch Denoting a protostsele in which protoxylem is at the center of the axis.

心始式：一种原生中柱的类型，在心始式中柱中，原生木质部位于轴的中央。
