Inversion of earth ' s neutral atmospheric parameters and bending angles with gps occultation data 掩星资料反演地球中性大气参数折射角方法研究
Laser light incident on the polycarbonate surface will be refracted at a greater angle into the surface 激光射入聚碳酸脂表面将产生较大的折射角。
Prk was the first surgical procedure developed to reshape the cornea , by sculpting , using a laser 光性折射角膜切削术使用激光塑形,它是最早的重塑角膜的外科手术。
Being bent with slightly different angles , the visible white light is broken up into it ' s components 这一微小的折射角度的差别造成白色光线在折射后分散成构成它的七色光,象一个彩虹的图案。
In prk , the top layer of the cornea , called the epithelium , is scraped away to expose the stromal layer underneat 光性折射角膜切削术使用的方法是削去角膜的顶层,又称上皮层,来显露下面的基质层。
In addition , the vi has the ability to calculate the k value and sensor distance automatically 本虚拟探伤仪实现了探头前沿距离、折射角正切k这两个参数的自动标定,这是国内所有超声探伤仪没有实现的。
Radial keratotomy ( rk ) and photorefractive keratectomy ( prk ) are other refractive surgeries used to reshape the cornea 其他用于角膜重新塑形的外科手术还有放射状角膜切开术( rk )和光性折射角膜切削术( prk ) 。
On the base of experiments , this paper found the primary factor of caused atmospheric - vertical refraction . a formula to calculate the angle of atmospheric - vertical refraction is given 以实验为基础,找出了导致大气竖直折光的主要因素,给出了大气竖直折射角计算的实用公式。
