Results: Twenty eight out of 57 patients had clonal chromosome aberrations. Among the 28 aberrational chromosome,+8 presented in 8 cases, t (8; 21) translocation in 4 cases, 20q-in 2 cases, i (20q-) which was an rare recurrent chromosome abnormality in 1 case, and complex karyotype in 7 cases, but 5q-was not found in all the patients.

结果：MDS患者中异常核型率为49.12%(28/57)。28例异常核型患者中伴有＋8异常8例，t(8； 21)易位4例，20q-2例，少见的重现性异常i(20q-)1例，复杂核型7例，未见5q-核型。

Objective: To study the higher order aberrations of emmetropic and ametropic eyes with wavefront aberrometer.

目的：借助波阵面像差仪研究正视眼及屈光不正眼的高阶像差。

In this study, we use corneal topography and wavefront aberrometer to analyze corneal and total ocular high-order aberrations.

本研究利用电脑角膜地形仪、前导波像差分析仪及电脑分析软体；另外测量对比视力及对比敏感度作为视觉品质指标，以研究分析：一、年龄对病人角膜表面及眼球整体高阶像差的影响。

A new subjective wave-front aberrometer, which measures ocular wave-front aberrations, is studied. The working principle and design project are presented.

研究了一种用于测量人眼波前像差的新型主观式波前像差仪，给出了工作原理和实现方案。

Methods: Forty of cases 77 emmetropic and ametropic eyes were measured with an aberrometer based on Tscherning's principle with the pupils dilated. The Zernike coefficients and root mean square values of wavefront aberrations up to the 6th order were recorded and statistically analyzed.

40人77只正视眼及屈光不正眼，散瞳后用基于Tscherning原理的波阵面像差仪进行测量，记录高达6阶的波阵面像差Zernike系数和均方根值，并进行统计学分析。

The aberrometer can measure lower-order and higher-order aberrations accurately.

主观式波前像差仪能精确地测量出人眼的低阶和高阶像差，其应用前景广阔。

The leading type of chromosome aberrations was acentric fragment. Conclusion There is no direct relation be...

结论染色体畸变的主要类型是断片，染色体型畸变与有害作业工龄之间无明显的正相关，但随年龄增加有增高趋势。

The major type of chromosome aberrations was acentric fragment (ace, 59.3%).

染色体型畸变以断片为主(ace，59.3%)。

There was no significant difference of higher order wavefront aberrations between emmetropic and ametropic eyes. Comparing the age of 40 years or less with the age over 40 years, there were significant differences in RMS3 between the two under 7 mm pupil size, and statistical diffenences in RMS6 and RMSh between the two under 4 mm pupil size.

除第2阶像差均方根(RMS2)以外，正视眼及近视眼各阶像差平均RMS值在7 mm与4 mm瞳孔下，差异均无统计学意义。40岁及以下者与40岁以上者相比，在7 mm瞳孔时，两者第3阶像差均方根(RMS3)差异有统计学意义；而在4 mm瞳孔时，两者第6阶像差均方根(RMS6)及高阶像差均方根差异均有统计学意义。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
