Diagnosis/testing. A diagnosis of ocular albinism is probable in the presence of congenital nystagmus, iris translucency, and significant hypopigmentation of the ocular fundus periphery in males with normal skin pigmentation and foveal hypoplasia, reduced visual acuity, and aberrant optic pathway projection, as demonstrated by crossed asymmetry of the cortical responses on visual evoked potential. X-linked inheritance is documented by either a family history consistent with X-linked inheritance or the presence of typical carrier signs (irregular retinal pigmentation and partial iris transillumination) in an obligate carrier female.

诊断/检测。对于皮肤色素沉着正常、中央凹发育不全、视敏度降低以及视径投射异常（VEP，表现为视觉诱发电位中皮层反应的交叉不对称）的男性患者，当存在先天眼球震颤、虹膜半透明以及显著的眼基底层边缘色素减退的症状时，可被疑似诊断为眼白化病。X连锁性遗传则以存在与X连锁遗传一致的家族病史，或在一个应当为携带者的女性中存在典型的携带者迹象（视网膜色素沉着不规则以及部分虹膜透射）而被确认。

Corolla zygomorphic, ventricose funnelform, tube narrow at base, throat wide; limb oblique, ca. 2-lipped, upper lip 2-lobed or entire, lower lip 3-lobed with middle lobe larger.

左右对称的花冠，一侧臌，筒部狭窄在基部，喉宽；大的偏斜，约二唇形的瓣片，上唇2裂的或全缘，下唇3浅裂的具中部裂片。

Papovaviruses are also icosahedral symmetry viruses, but their capsid structures disobey the quasi-equivalence theory. Papovaviruse capsids are all composed of pentagons. Furthermore, these pentagons can not be connected directly, because there is a certain distance among them.

乳多空病毒尽管也是二十面体对称的病毒，但其衣壳结构违背了准等价原理，它们全是由五边形构建的几何实体，而且奇妙的是这些五边形不能直接拼接在一起，相互间存在一定的距离间隔。

Then we completed the first total synthesis of-Plakoridine A using Eschenmoser couping reaction as akey step. During the synthesis we found the choice of protecting groups and the configuration of the chiralcenter of the substrate play an important role to the key Eschenmoser reaction,so we think our successwould be of guide for synthesizing other polysubstituted pyrrolidines or piperidines.

在论文的第一章中，我们先以易得的对羟基苯乙酸乙酯为原料经多步反应制得了所需的β氨基酸酯，然后利用立体选择性的Aldol缩合反应和内酰胺化反应制得了Plakoridine Alactam，随后，以Eshenmoser缩合反应为关键步骤完成了生物碱-Plakoridine A的首次不对称全合成。

Two approaches for the asymmetric syntheses of naturally occuring eudesmane-type triol kudtriol and 5-epi-kudtriol as well as their C-11 epimers were achieved starting from-dihydrocarvone through six and seven steps, respectively.

以-二氢香芹酮为原料，用两条合成路线分别经六、七步反应完成了三羟基桉烷类天然产物Kudtriol、5-epi-Kudtriol及它们的C-11位差向异构体的不对称全合成。

Based on Bresenham's algorithm,the thesis gives a fast technique for drawing anti-aliased straight line according to the symmetry of the straight line, dissertates the arithmetic of antialiasing the compass small character and offers the program of the compass picture.

本文基于Bresenham算法，依据直线的对称生成原理，提出了一种新的直线快速反走样技术，对罗盘字符的反走样算法做了进一步的论述，编制了全罗盘画面的程序。

Its width should be no less than half the of the face at the same height and, for the best effect, both upper and lower lips need to be symmetrical each side of the mid-line of the face.

张开的嘴宽度不能小过半边脸的宽度，上唇与下唇两边嘴角要对称，如此才能交出最完美的笑容。我有兴趣坚持学成英语，全靠《英语阅览专家》，特别推荐： http：//www.enzcn.com
