差

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。

All patients were examined by left ventricular angiograph by which ejection fraction and left ventricular end-diastolic pressure were measured. Results The change of left ventricular end-diastolic pressure after angiography of the patients in DM group was significiantly higher than that in non-DM group.

结果 DM组患者造影前后左室舒张末压的差值(D3)明显高於非DM组的患者，两组间的射血分数无明显差异，年龄增加、糖尿病、 EF的降低，与造影前后左室舒张末压的差值呈负相关。

Poor consciousness,flushed cheeks,anisocoria,accelerated breathing and fever indicate poor short-term prognosis while gruff breathing,foul breath, spontaneous perspiration,dry stool indicate good short-term prognosis.

其神志差、两颧潮红、瞳孔不等、呼吸急促、发热预示差的近期预后，呼吸气粗、口臭、自汗、便干提示近期预后较好。

Poor consciousness,flushed cheeks,anisocoria,accelerated breathing and fever indicate poor short-term prognosis while gruff breathing,foul breath, spontaneous perspiration,dry stool indicate good short-term prognosis.

其神志差、两颧潮红、瞳孔不等、呼吸急促、发热预示差的近期预后，呼(来源：7bABC论5f5f文网www.abclunwen.com)吸气粗、口臭、自汗、便干提示近期预后较好。

In the area with the tuberculosis as a frequently-occurring disease,most of the cases could be diagnosed definitely by using the examination of CT and cystoscopy,seeking tuberˉcle bacillus in urine by microscopy were valuable for early diagnosis,B ultrasonographycould not provide effective inˉformation for diagnosing,KUB+IUP could provideinformation for the diagnosis and prognosis,conservative treatment brought poor curative effect,early treatment and regular using antituberculotic were significant to the prognosis.

在结核病高发地区，CT和膀胱镜检查是最重要的方法，尿中找抗酸杆菌对早期诊断有意义，B超检查特异性较差，KUB+IUP对诊断和预后判断有意义，保守治疗效果差，早期治疗和正规抗痨治疗对病人预后有重要意义。

Therefore this way is feasible, and the system is simplified.⑤A procedure of analyzing in target echo theory and simulation for APAR is described in the dissertation.

因而在视频上模拟目标回波的多普勒频率的方法是可行的，并且简化了系统；⑤对机载相控阵雷达目标回波的理论分析和模拟实现进行了深入研究，在目标回波模拟系统方案中采用了用一路目标信号通过和、差波束天线方向图增益进行调制并用移相器控制和、差通道相位的方法，产生目标三个通道的信号。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
