Methods One hunderd amd ten human subjects (one hunderd and seventy-four eyes) were included in this research. Retinoscopy was made to measure refractive errors, corneal topographer was measured by corneal topography system, Tonometry was used to measure IOP, Ultrasonagraphy was applied to measure anterior chamber length, len thickness and vitreous length respectively, Laser interference biometer was used to measure axial length, Optical coherence tomography was used to measure retina thickness of fovea area. Based on spherical equivalent subjects were divided into four groups: emmetropia group (SE0.50D), low-myopia group (-0.50D≤SE3.00D), moderate myopia group (-3.00D≤SE6.00D) and high myopia group (SE≥-6.00D).

Through simulation and computation, some critical values to contral interferences are obtained. These values have directive significance to the design and deployment of WRAN.(4) New methods to measure and analyze spectrum aredevelopedAccording to the shortages of previous spectrum measurements, new methods to measure spectrum occupancy in wide-band and multi-point synchronously is proposed in this dissertation, and the tests last a whole week; the relativities of licensed services are considered when test points are selected. More importantly, data mining and in-depth analysis are carried out with the huge amounts of test data, and a channel analysis method using Channel Vacancy Duration and Service Congestion Rate are proposed. The spectrum relativities of 3-dimension in time, space and frequency are researched also. The correlativity between channel state and history information is discoved, and which will provide the scientific basis to channel modeling, spectrum analysis and decision of CR users.
