上叉

"The white-covered table was arrayed with pretty dishes and lighted with a four-armed candelabra, each light of which was topped with a red shade."

铺着白色台布的餐桌上摆着精美的盘子，点着四叉灯台，每盏灯上安着一只红色灯罩。

They cut out the thigh-bones, wrapped them round in two layers of fat, set some pieces of raw meat on the top of them, and then Chryses laid them on the wood fire and poured wine over them, while the young men stood near him with five-pronged spits in their hands.

然后剔下腿肉，用油脂包裹腿骨，双层，把小块的生肉置于其上。老人把肉包放在劈开的木块上焚烤，洒上闪亮的醇酒，年轻人手握五指尖叉，站在他的身边。

At last he read it carefully over, stopping at some of the numbered paragrapbs, and marking several of them with a pencilled cross; then he folded the sheet of foolscap, went over to a cabinet on the opposite side of the room, unlocked it, and placed the paper in that very pigeon-hole into which he had thrust Alicia's letter--the pigeon-hole marked Important.

最后，他把记录仔仔细细地读了一遍，在某些标明号码的段落上停顿一番，又用铅笔在某些段落上打个叉做个记号；然后便把这张大页书写纸折叠起来；他走到房间对面一个密室跟前，开了锁，把这张纸放进了鸽笼式文件架里——就是他存放艾丽西亚来信的、那个标明"要件"的文件架里。

Someone had dumped a forkful of hay from the stack into the pit.

原来有人曾从干草堆上往上坑里扬了一叉草。

"Sorry, sir," John called down from the hayloft."I ain't had time to toss it back down again after you pitched it up while the Iowa folks were here."

約翰在乾草閣上高聲回答：「對不起，愛荷華州那些人來訪的時候，你把乾草叉了上來，我還未有時間再次扔下去。

He toasted his bacon on a fork and caught the drops of fat on his bread;then he put the rasher on his thick slice of bread; and cut off chunks with a clasp-knife , poured his tea into his saucer, and was happy.

他叉起咸肉放在火上烤，让肉油滴在面包上；然后把薄片咸肉放在厚厚的面包上，用一把折刀一块一块切着吃，把茶倒进小碟子里喝，这时，他快活了。

The main jobs of this paper are as followed: 1 The reuse of the frame design technology for aircraft assembly fixtures is researched. a frame line part library is built with the templet driven technology, the reuse of the frame line part come true by the tools for instantiation and instance modification. The design resources are effectively used, some repeating work is cut. 2 Two methods to obtain the assembly feature are proposed: the straight way by the Enumeration method and the indirect way by project features to the assembly plane. All of the assembly features of the frame and the adjustable bearings are obtained by these two methods which makes the frame automatic assembly technology for aircraft assembly fixtures come true. 3 The frame automatic assembly technology aircraft assembly fixtures based on assembly features is researched. A binary tree assembly model is used to express the assembly information of the frame for aircraft assembly fixtures, the automatic assembly between the frame, the aircraft and the adjustable bearing is completed within the three steps: distribute, obtain and evaluate assembly feature. Finally, the efficiency of the frame assembly design is proved. 4The frame interpart modeling technology for aircraft assembly fixtures is researched, the intersection methods are concluded and the arithmetic of the single-cut, double-cut and inter-cut intersection is proposed, the interpart fast modeling of the frame design for aircraft assembly fixture come true. 5Based on the researches mentioned before, a sub-system of frame fast design for aircraft assembly fixture is developed on CATIA. The sub-system is used to design the aircraft assembly fixtures in a large aeronautics corporation and make a good- effect.

论文的主要工作如下： 1研究了飞机装配型架骨架设计重用技术，在总结归纳骨架线框结构类型的基础上，应用模板驱动的方法建立了骨架线框库，通过骨架线框零件的实例化和离线编辑实现骨架线框的重用，有效利用设计资源，减少重复劳动； 2提出穷举几何对象的装配特征直接获取方法，遍历零件模型的几何对象，从中捕捉所需装配特征，该方法简捷、高效；提出向装配面投影的装配特征间接获取方法，该方法在现有特征基础上生成装配特征，解决了部分装配特征难以直接获取的问题； 3研究了基于装配特征的飞机装配型架骨架自动装配技术，采用一种二叉树装配模型表达骨架的装配关系，并通过装配特征的分配、获取和赋值三个步骤，实现了骨架分别与飞机产品和可调支承的自动装配，避免了繁琐的人工交互操作，提高了骨架设计的效率和规范化程度； 4研究了飞机装配型架骨架零件间建模技术，在总结归纳骨架元件相贯处理方式的基础上，提出了骨架元件单剪切相贯、双剪切相贯和互剪切相贯的实现算法，简化了骨架相贯处理的过程； 5基于以上研究，在CATIA平台上开发了飞机装配型架骨架快速设计子系统，并应用于某大型航空企业的装配型架设计，提高了设计效率和设计质量。

And they shall put upon it all its utensils with which they minister upon it, the firepans, the forks, and the shovels, and the basins-all the utensils of the altar; and they shall spread over it a covering of porpoise skin, and put in its poles.

4：14 又要把坛上供职用的一切器具，就是火盆、肉叉、铲子、盘子，一切属坛的器具都摆在坛上，又铺上海狗皮盖，并把杠穿上。

There he was, balanced precariously eleven feet high, painting the noses red on the ugly metal faces, crossing their eyes, giving them moustaches and goatees, and he had managed to deface six out of the seven goblins when Mrs. Wren walked in and caught him.

然后他在十一尺高的地方摇摇晃晃地把那些丑陋的金属脸的鼻子涂上红色，在它们眼睛上画叉，并画上胡子，当瑞文女士走进来抓他的时候，他正打算丑化七个小妖怪中的第六个。

The result showed that the surface architecture and ultrastructure of I.punctatus ' gill and secondary gill lamellae were similar to those of other teleosts. The surface of gill arches and gill rakers was covered with pavement cells which were characterized by circular microridges, and secreting-holes were found among cells on the surface of gill arches. The base part of gill rakers were bigger in terms of diameter. The pavement cells' surface of gill filaments' middle part was characterized by microridges with fine lateral protuberances on both sides which were either fused or interruped, while the microridges disappeared on the pavement cells' surface on both top and base parts of gill filaments, forming dense granulated protuberances. The height and interlamellar space of secondary gill lamellae in I.punctatus were relatively higher and bigger, respectively.

结果表明，斑点叉尾鮰鳃的表面结构和微细结构与其他硬骨鱼类基本相似，鳃弓和鳃耙表面被具环形微嵴的扁平上皮细胞所覆盖，鳃弓表面细胞之间有孔洞；鳃耙基部较粗壮；中部鳃丝上皮细胞表面的微嵴两侧有细小的横突，有些微嵴出现融合或间断；端部和基部鳃丝上皮细胞表面的微嵴消失，形成密集颗粒状突起；鳃小片的高度和片间距较大。
