Oculocutaneous albinism type 4 (OCA4) is characterized by hypopigmentation of the skin and hair plus the characteristic ocular changes found in all other types of albinism, including nystagmus; reduced iris pigment with iris translucency; reduced retinal pigment with visualization of the choroidal blood vessels on ophthalmoscopic examination; foveal hypoplasia associated with reduction in visual acuity; and misrouting of the optic nerves at the chiasm associated with alternating strabismus, reduced stereoscopic vision, and an altered visual evoked potential.

疾病特征： 4型眼皮肤白化病（OCA4）的特点是皮肤和头发的色素减退以及所有白化病类型都有的典型的眼部改变，包括眼球震颤、虹膜色素减少而使其呈半透明状、视网膜色素减少而使得脉络膜血管在眼底镜检时可见、与中央凹发育不全导致的视敏度降低以及视神经交叉处路径错误引起的交替性斜视、立体感降低和视觉诱发电位改变。

Under a lower pressure, the relationship between C/H and CO adsorption quantity was a beeline and the CO adsorption quantity increases with the of C/H ratio. The relationship between C/H and CO adsorption is a concave curve with the pressure increasing, and the higher the pressure, the higher the discrete degree.

A nonlinear eddy-viscosity turbulent flow model, which adopted third-order correlation of stress tensor and strain tensor, was modified and applied to flow computing of turbulent flow of internal combustion engine.

把采用了应力张量和应变张量的三阶相关关系的一个非线性涡粘度湍流模型进行修正后应用于内燃机缸内湍流流动计算，用此模型对几种ω形凹坑燃烧室内燃机汽缸内的流动进行计算，特别考查不同结构燃烧室内各处的湍能的变化，给出了燃烧室结构对缸内湍能影响结果，结果表明，凹坑结构时内燃机缸内湍能的分布和平均湍能的大小影响很大，可适当调整燃烧室结构来改变缸内湍流结构。

First of all, some structure parameters, such as the dimension scale of cavity walls, thelocation of primary flow injection holes, the entrance angle of main flow, and so on, havebeen studied, focusing on their influence to the cavity flow field, the forming of vortexes,and the pressure drop in the combustor.
