新PCI生物测量仪的重复性、再现性和一致性

open access: yesZhongshan Daxue xuebao. Yixue kexue ban
目的评估基于部分相干干涉测量原理的新型眼生物测量仪Myopia Master用于测量眼轴、角膜曲率的重复性和再现性,比较其与IOL Master 500的一致性。方法同一名操作者随机先后顺序使用新型眼球生物测量仪Myopia Master和IOL Master 500采集屈光不正儿童右眼数据,以评估两仪器间一致性。其中部分儿童接受了Myopia Master重复性、再现性评估。数据包括眼轴(AL)、平坦角膜曲率(Kf)、陡峭角膜曲率(Ks)、平均角膜曲率(Km)、J0、J45。结果136人纳入一致性研究,

Creep-rupture reliability analysis [PDF]

open access: yes
A probabilistic approach to the correlation and extrapolation of creep-rupture data is presented. Time temperature parameters (TTP) are used to correlate the data, and an analytical expression for the master curve is developed.
