查询词典 refraction angle

The difference between the observation atmospheric refraction and Pulkovo table is about 15 arc second at the zenith distance of 84 degree.

在天顶距84°时，与普尔科沃大气折射表的差值约为15。

The method does not depend on strict local parameters and precise instruments, while the observational principle is relatively simple. An experimental observation was carried out with a simple telescope with large field of view at Xinglong station of NAOC at the end of 2007. The atmospheric refraction from the zenith distance of 44.8 degree to 87.5 degree is gotten by the differential method, which proves the feasibility of the method tentatively.

该方法不依赖于严格的地方参数和复杂精密的观测仪器，并且观测原理相对简单。2007年底，利用一台简易的大视场望远镜在兴隆观测站进行了试验观测，根据较差方法实测得到真天顶距44.8°至87.5°的大气折射值，初步证明了大气折射较差测量方法的可行性。

Horizontal strabismus diorthosis has effect on eye refraction and cornea.

水平斜视矫正术对眼的屈光有影响，对角膜的影响是可以恢复的。

Postoperative manifest refraction was also improved by surgery, showing minimal but significant regression after 1 year. Final BCVA loss was seen in 10 eyes of 7 patients; in 7 cases, there were obvious reasons such as the progression of cataracts in 3 eyes, epithelial disintegrity due to dry eye in 2 eyes, irregular astigmatism due to flap striae in 1 eye, and age-related macular dystrophy in 1 eye.

手术后的显然验光视力也有提高，在1年后表现为极微量却显著的回退。7例患者的10只眼发生了最佳矫正视力的下降，但均有明显原因，如3只眼发生了白内障，2只眼角膜上皮不完整，1只眼由于角膜瓣皱褶导致不规则散光，1只眼为年龄相关性黄斑萎缩。
