To overcome the deficiency in managing and operating the global data of both Longitude-Latitude Grid and Quaternary Triangular Mesh, a new discrete global grid-Degenerate Quadtree Grid is put forward, and its tessellating principle and coding rule are presented. Then, its geometrical distortion is calculated and analyzed in details.

为有效解决经纬度格网与四元三角网在全球空间数据管理与操作中存在的不足，提出一种新的全球离散格网剖分方法―球面退化四叉树格网，给出该格网的剖分原理与编码规则，并对其进行几何变形计算与分析。

With the feature points detected from the linked list, the geometrical model of leaf shape is upbuilt by the rational cubic spline interpolation.

The panels of the mosaics showed squares in geometrical design, as also wreathes overlaid with stylized bouquets, all enclosing a central bouquet decorated with a cross.

整个四方几何图形设计都是用马赛克镶嵌而成，就算是麻花辫盖著方型花格也一样。

He had begun an investigation, as he imagined, with the severe and equal integrity of a judge, desirous only of truth, even as if the question involved no more than the air-drawn lines and figures of a geometrical problem, instead of human passions, and wrongs inflicted on himself.

但在他着手进行这一调查的过程中，一种可怕的迷惑力，一种尽管依然平静、却是猛烈的必然性，却紧紧地将这老人攫在自己的掌握之中，而且在他未完成它的全部旨意之前。绝不肯将他放松。

照他自己的想象，他是以一个法官的同等的严峻与公正来开始一次调查的，他只向往真理，简直把间题看得既不包含人类的情感，也不卷入个人的委屈，完全如同几何学中抽象的线和形一般。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
