查询词典 absolute refractive index

On the landscape level, the regional landscape heterogeneity is increased and the connectivity reduced, which presents the increase of Shannon's diversity index and Evenness Index, decrease of dominance index and increase of fragmentation index. On the class level, it shows that human disturbance on landscape is intense during the past five years, anti the disturbance to artificial landscape mote intense luau that on semi-natural landscape, which means that the fragmentation index of semi-natural landscape is relatively smaller while that of the artificial landscape is larger.

从景观水平上看，区域景观异质性在增大，景观斑块的连通性降低，表现为多样性指数和均匀度指数呈增加，优势度指数减小；从类型水平上看，5年间人类对景观的干预程度较大，对人工景观的干扰强于半自然景观，体现在半自然景观类型的分离度较小，而人工景观类型的分离度较大。

Absolute refractive index.

绝对折射率。

Results: The refraction results of the Allegretto Wave Analyzer were very unstable. The spherical, cylinder diopter and the axis of the cylinder varied greatly. The refractive errors were large while the refractive errors were little by the subjective refraction examinations. During the wavefront examination, spots of the laser matrix were blurring, and the reproducibility was not good. Wavefront analyses showed that the Array pseudophakic eyes had relative large coma while the patients had no obvious symptoms.

研究结果：像差分析仪检测得的屈光度结果十分不稳定，球镜度、柱镜度、散光轴都变化很大，可重复性差，检测的屈光不正度数较大，而主觉验光时，患眼的屈光不正度数较低。5只眼的光学矩阵的测量点均非常模糊，且测量结果的可重复性较差，像差分析显示，Array人工晶状体有很大的第三阶彗差，但患者的自我感觉良好。

With the increase of the refractive error before refractive surgery, the asphericity of the anterior cornea changes from negative to positive, which leads to the increase of the spherical aberration.

考虑了激光斜入射和反射后的术后非球面系数与Munnerlyn公式的预期值差别不大，术后非球面系数的大小与光区的关系不大。

In theory, there is no error for the refractive seismic exploration by permuting the focus and the cymoscope. In some especial condition, it would be the only choice because that refractive seismic exploration is needed, but the error can not be neglected be cause of various factors.

在理论上，用源检互换的方法进行折射地震勘探是没有误差的，在某些特殊条件下无法铺设检波器而又必须进行折射地震勘探时它也是唯一的选择，然而，在实际工作中，由于各种因素的影响，其误差是不可忽略的。

The functional relation between incident angle and refractive angle of energy flow is obtained. According to this relation, we can restructure the refractive angle as negative or positive readily by selecting suitable permittivity and permeability tensors.

导出了电磁波的入射角和能流折射角之间的函数关系，根据此关系可方便地选择合适的介电张量和磁导率张量，使特定入射角所对应的折射是正或是负。

Myopia: As axial length is too long, due to refractive eye refractive power of the system is too strong, resulting in 5 meters away from the formation of the parallel light rays focus before the retina.

近视眼：由于眼轴过长，由于眼球屈光系统的屈光力过强，以致5米以外的平行光线在视网膜之前形成焦点。

After complete ocular examinations, the peripheral chorioretinal lesions were recorded. The refractive status was recorded as the spherical equivalent. The data were analyzed for the relationship between the peripheral chorioretinal lesions and patient's refractive error, gender and age.

经完整的眼科检查及眼底检查并详细记录周边视网膜变化，然后分析这些周边视网膜变性与病人屈光度及年龄之相关性。

Myopic shift of refractive error was associated with female gender, older age, and with higher myopic or hyperopic refractive error at the baseline examination.

屈光不正向近视眼方向改变容易发生在女性、年龄偏大、基线检查时近视眼或者远视度数大者。

The ocular accommodation has a great influence on refractive components. It is not only the process by which the refractive power of the lens is increased. But the lens itself moved forward relatively. The accumulation effects of accommodation induced by near-work is the main cause of myopia developed in children. The asymmetry of corneal surface was not only related to keratometer K1 and K2 , even the curvature within the same horizontal or vertical meridian was asymmetry.

调节本身不仅是传统意义上的睫状肌收缩和晶状体变凸，同时还伴有晶状体的相对前移；调节对眼的几乎所有屈光构成因素有着显著的影响，视近活动的累积效应是儿童近视眼发生的主要原因；角膜的非球面性不但表现为两个相互垂直子午线的曲率不等，即便是在同一垂直或水平径线上的屈光分布也是非对称的。

The witness also told the jury at the Royal Courts of Justice in London that he saw a paparazzo fighting with a member of the public who was trying to stop him taking pictures in the minutes before the emergency services arrived.

他还告诉在伦敦皇家法庭的陪审团，在急救服务到来之前，他当时看见一个狗仔队正和一群阻止他拍照的人打架。

The entire N／C program on a tape is made up of an accumulation of these successive data blocks.

纸带上的整个数控程序由这些连续数据单元连接而成。
