First, this paper, in the field of intrinsic geometry, studies the geometric problems on garment design, as well as applies the frame and semi-geodesic coordinates to prove the fundamental theorem of being a developable surface.

文中首先在内在几何学的层次上，研究了服装设计所涉及的几何学问题，应用标架与半测地坐标方法证明了曲面成为可展面的基本定理，研究了可展面的分类及其性质，考虑到服装三维几何造型的需要，证明了组合式可展面各组成片相切连接条件的命题，作为构造可展面的理论依据，证明了单参数平面族的包络面必为可展面的命题，在此基础上发展出服装几何造型的"刮大白"方法以及相关的三种构造可展面的解析方法。3D→2D的变换是三维服装CAD的重要内容之一，其几何学实质是曲面的定长映射，文中总结了定长映射即可展面在平面上展开的基本准则，在这一准则的指导下，结合服装设计与相关领域的要求，讨论了可展面在平面上展开的解析方法与数字方法，上述内容确立了服装设计几何学的基本框架。

We proved that the necessary and sufficient condition that the developable surfaces touch the second focal surface along the orthogonal trajectories was that the base surface S was a developable surface.

It shows that some of the geometric construction algorithms that exist for curves can be also generalized to the design of developable surfaces.

基于将可展曲面作为平面单参数族包络面的思想，给出在B啨zier和B样条基下可展曲面的参数表示形式。

After about two Years an odd Circumstance presented it self which put the old Thought of making some Attempt for my Liberty, again in my Head: My Patron lying at Home longer than usual, without fitting out his Ship, which, as I heard, was for want of Money; he used constantly, once or twice a Week, sometimes oftner, if the Weather was fair, to take the Ship's Pinnace, and go Out into the Road a-fishing; and as he always took me and a young Maresco with him to row the Boat, we made him very merry, and I prov'd very dexterous in catching Fish; insomuch that sometimes he would send me with a Moor, one of his Kinsmen, and the Youth the Maresco, as they call'd him, to catch a Dish of Fish for him.

大约两年之后，出现了一个特殊的情况，这使我重新升起了争取自由的希望。这一次，我主人在家里呆的时间比以往长。据说是因为手头缺钱，他没有为自己的船配备出航所必需的设备。在这段时间里，他经常坐一只舢舨去港口外的开放锚地捕鱼；每星期至少一、两次，天气好的话，去的次数更多一些。那只舢舨是他大船上的一只小艇。每次出港捕鱼，他总让我和一个摩尔小孩替他摇船。我们两个小年轻颇能得他的欢心，而我捕鱼也确实有一手，因此，有时他就只叫我与他的一个摩尔族亲戚和那个摩尔小孩一起去替他打点鱼来吃；那个摩尔小孩名叫马列司科。

Fight with the Imperium's Space Marines to guard mankind's last hope, or reign as the diabolic forces that worship Chaos.

使用Imperium's Space Marines种族来保卫人类最后的希望，或者选择嗜好混乱的魔族。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
