Seawater intrusion mechanism and its 3D numerical simulation are further explored and researched in this paper. On the basis of the classical theory of fluid mechanics, it built the ideal model of seawater intrusion, and attained the speed in flow field which gradually decreased along with the increasing distance of curvature center along the principal normal in the course of seawater intrusion.
以流体力学经典理论为基础，建立了海水入侵内陆的理想模型，得到在海水入侵内陆的过程中沿弯曲流线的主法线方向，流场中速度随着距曲率中心距离的增大而逐渐减小，根据流线上的速度分布，并可表示出流场中的流线方程，可确定一定条件下海水入侵内陆的速度和方向。

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).
对近视患者及正视者110例（174只眼），主觉加检影验光行屈光检查，采用Humphrey测量角膜平均曲率，非接触式眼内压测量仪测量眼内压；A与B型超声诊断仪测量前房深度、晶状体厚度、玻璃体腔长度及眼轴长度；角膜测厚仪测量中央角膜厚度(CCT，centercornealthickness)；光学相干生物测量仪测量眼轴长度；光学相干断层扫描仪测量黄斑中心视网膜厚度；按等效球镜度数(SE， sphericalequivalent)不同分正视组(SE0.05D)、轻度近视组(-0.50D≤SE3.00D)、中度近视组(-3.00D≤SE＜-6.00D)、高度近视组SE≥-6.00D）。
