非寻常光

Refraction regularity of extraordinary ray in uniaxial crystal with arbitrarily oriented optical axis;2. In the case of optical axis of uniaxial crystal being parallel with the incident plane, the angle of refraction of extraordinary ray are calculated by using Fermat's principle.

在单轴晶体的光轴与入射面平行的情形下用费马原理计算非寻常光光线的折射角，然后就怎样定义非寻常光作些讨论，最后在单轴晶体的光轴任意取向的普遍情形下给出计算非寻常光光线折射方向的公式。

It is proven that the choice of entrance of light and the beginning of the tangent from crystal surface has no effect on resolving the final direction of light in crystal by Huygensdiagraph and a conclusion that light will still spread in line in singleaxiscrystal is drawn.

当光波入射至单轴晶体时，由于晶体结构的各向异性，入射光波在晶体中将分成两束，一束称o光或称寻常光，另一束称e光或非寻常光，这种现象被称为双折射。对于o光和

The cooperation of 8-MOP/UVA could induced dermis of the non- lesion back skin of vulgar psoriatic patients and the cultured dermic fibroblasts produced large aging-associated mutations of mtDNA rapidly, it is feasible to establish human models in vivo and in vitro which could produced large aging-assoiated mutations of mtDNA rapidly for studies of the mechanisms of mutations of mtDNA in skin photoaging.

2.8-MOP/UVA可诱导寻常型银屑病患者背部非皮损区真皮组织及培养的成纤维细胞迅速产生光老化相关的mtDNA突变，建立迅速产生光老化相关mtDNA突变的体内外模型，利用该模型进一步研究mtDNA突变在光老化皮肤中的产生机制及其在皮肤光老化形成中的作用是可行的。

The cooperation of 8-MOP/UVA could induced dermis of the non- lesion back skin of vulgar psoriatic patients and the cultured dermic fibroblasts showed up photoaging-characteristic changes of histology and biology rapidly, it is feasible to establish human skin photoaging models by selected the human skin of sun-protected sites treatment with PUVA and cultured dermic fibroblasts treatment with 8-MOP/UVA as studied objects.

1.8-MOP/UVA可诱导寻常型银屑病患者背部非皮损区真皮及培养人类真皮成纤维细胞迅速出现具有光老化特征性的组织学及生物学特性改变，以PUVA治疗的非暴露部位皮肤及8-MOP/UVA作用的培养真皮成纤维细胞作为研究对象建立人类皮肤光老化模型是可行的。

However, the molecular mechanisms underlying premature aging up 8-MOP/UVA are as yet unknown. In our studies, dermis of the non-lesion back skin of vulgar psoriatic patients who had been treated by PUVA and the cultured foetus dermic fibroblasts were selected to be observed.

本课题以PUVA治疗寻常型银屑病患者背部非皮损区真皮及培养的胎儿真皮成纤维细胞为对象，采用HE染色、Verhoeff染色、电镜、酶组织化学、免疫组织化学、原位杂交、流式细胞计数仪、三引物PCR、PCR-SSCP技术及PCR产物直接测序等技术和方法，研究了8-MOP/UVA对皮肤光老化形成的影响及芳维A酸乙酯的拮抗作用。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
