In order to obtain symmetry and parallel polarized light,the double Wollaston prism is amended. After getting symmetric polarized light at a big splitting beam angle,an ordinary triangular prism is added so that the symmetric light beam can be divided into parallel light beams.

为了获得对称且平行分束的偏振光，对双Wollaston棱镜进行了修正，在获得大分束角的对称偏振光后，配合普通玻璃三棱镜，使对称分束光变成平行分束光，通过改变三棱镜与双Wollaston棱镜间的距离来改变平行光的剪切距离。

In order to obtain symmetry and parallel polarized light, the double Wollaston prism is amended. After getting symmetric polarized light at a big splitting beam angle, an ordinary triangular prism is added so that the symmetric light beam can be divided into parallel light beams. The distance between the triangular prism and the double Wllaston prism is changed so that the distance of the shearing parallel light can be changed.

Three-way data analysis (Chapter 1 to 5 of Part Ⅰ): In terms of the symmetry of trilinear model, several statistical criteria including coupled vectors resolution errors and slice-wise diagonalization error are proposed for statistically plausible resolution of trilinear data. These criteria form the basis for the development of novel trilinear analysis procedures. In Chapter 1 the coupled vectors resolution method is developed for second-order calibration.

三阶数据分析：利用三线性模型的对称性，提出了耦合向量分辨误差与同时对角化误差等多个三线性分辨的统计准则，这些准则为今后发展三线性分辨方法提供了重要依据。

IR分析表明，复合水泥浆体水化产物相晶体结构的对称性较SC的高，由此可推测其稳定性增强，浆体耐久性好。SEM表明，水化浆体中的C-S-H凝胶交织成网络状，结构致密。

Light holds between its hands The white hill and black oaks, The path that goes o, The tree that stays; Light is a stone that breathes By the sleepwalking river, Light: a girl stretching, A dark bundle dawning; Light shapes the breeze in the curtains, Makes a living body from each hour, Enters the room and slips out, Barefoot, on the edge of a knife; Light is born a woman in a mirror, Naked under diaphanous leaves, Chained by a look, Dissolved in a wink; It touches the fruit and the unbodied, It is a pitcher from which the eye drinks clarities, A flame cut in blossom, a candle watching Where the blackwinged butterfly burns; Light opens the folds of the sheets And the creases of puberty, Glows in the fireplace, its flame becomes shadows That climb the walls, yearning ivy; Light does not absolve or condemn, Is neither just or unjust, Light with impalpable hands raises The buildings of symmetry; Light escapes through a passage of mirrors And returns to light: Is a hand that invents itself, An eye that sees itself in its own inventions.

光 双手拥着白色山峦与黑色橡树林，前行的路，停留的树；光是梦游的河旁呼吸的石光：一个女孩舒展，一束暗色破晓。光勾勒出帘中微风的形状，每时每刻造出一个鲜活的身体，光著脚，踩著刀刃；蹑入房间，又溜走；光是镜中诞生的女人，裸露在透明的叶底，被目光锁定，瞬间消逝；它触摸著果实和无形，眼睛在它的水罐饮著清晰，火焰绽放如花，蜡烛目睹黑翅的蝴蝶燃烧光展开被单的折皱与青春期的皱痕在壁炉里光芒焕发，它的火焰成影在墙上攀爬，怀恋著长春藤光既不赦免也不谴责无公平与不公平而言光，用无法察觉的双手举起对称的建筑；光在镜子的通道里逃遁返回于光：一只发明自己的手，一只在自己的发明中看到自己的眼。
