A 2D PIC model was used to simulate the PIII process for a planar target. The simulation results in one whole pulse show that the sheath expands with a decreasing speed and the sheath shape would change form elliptically cylindrical to circularly cylindrical. The dose distribution of ion implantation in the target surface is not uniform, and the concentration depth profiles of retained dose are considerably different, in different positions of the target.

本论文采用二维粒子模拟方法对等离子体离子浸没注入技术进行了模拟研究，在一个完整脉冲时段内，等离子体离子浸没注入平板靶的模拟过程表明：等离子体鞘层的扩展先快后慢，鞘层形状由椭圆柱形向圆柱形演化；注入离子剂量在靶表面的分布是非均匀的；在靶的不同位置注入的离子在改性层中的浓度深度分布有显著差别。

Results The axial length of eyeball was gradually decreased during the adult years of life accompanying with the increases of corneal and lens refractive powers and a decrease of anterior chamber depth fur maintaining a emmetropia status, and the steepness and thickness of lens, shallowness of anterior chamber contributed to emmetropia by decreasing the refractive index of lens.

结果 随着年龄增大，眼轴逐渐变短，但同时伴有角膜、晶状体屈光力的增大及前房深度的变浅以维持正视状态，晶状体的增厚、曲率的变大及前房的变浅可能通过屈光指数的减小同样维持了正视状态。

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).
