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.

And tell you the principle concerning bike,we can learn how and when it was invented and its basic structure as well from the passage.we got the history of bike and when it become popular,these are really interesting.although we usually ride bike around,we're not familiar with the history and the basic structure of it.after learning the unit,it give me a fresh knowledge of bike,and also tell us commonsensibles like how to forbit downdipping while riding in muddinesses and so on.it's a great help for us.because why don't learn more to keep our bikes more safe?

而且从文章告诉我们自行车是怎么样发明的？什么时候发明的？它的构造又是怎么样的？让我们了解了自行车的历史。以及它是什么时候开始流行的。这些都相当有意思。虽然平时我们经常骑脚踏车，可对他的历史来源和它的简单构造也不是很清楚，但学了这单元之后，使我对脚踏车又有了一个新的认识。而且它还告诉我们，当我们骑在泥泞的地面时，怎么样避免下沉？等等一些常识性的问题，可以让我们在现实生活中运用到，这是起着很大作用的，因为多点了解就能让自己的行车得到更好的安全保证。何乐而不为呢？

This paper generalizes the conclusion of Perfect nonlinear S-boxes by Nyberg(1991), and introduces the conception of inverse regular generalized vector Bent function. It shows that for inverse regular generalized vector Bent function f with even variables, m is no more than half of?. It also shows that when the input dimension n is odd, the regular generalized vector Bent function and the inverse regular generalized vector Bent function do not exist. This may prevent the cryptology designer from seeking the inexistent function.

摘要该文完善并拓展了Nyberg(1991)的关于广义向量Bent函数性质的结论，相应于Nyberg给出的正则广义向量Bent函数，提出了&负则的广义向量Bent函数&的概念：得到有偶数个输入的负则的广义向量Bent函数输出维数也不大于输入维数的一半；证明了奇数个输入的正则和负则的广义向量Bent函数都不存在，这些结果的给出，可使密码设计者避免一味去寻找某类不存在的函数。

Now transmuted, we swiftly escape, as Nature escapes; We are Nature—long have we been absent, but now we return; We become plants, leaves, foliage, roots, bark; We are bedded in the ground—we are rocks; We are oaks—we grow in the openings side by side; We browse—we are two among the wild herds, spontaneous as any; We are two fishes swimming in the sea together; We are what the locust blossoms are—we drop scent around the lanes, mornings and evenings; We are also the coarse smut of beasts, vegetables, minerals; We are two predatory hawks—we soar above, and look down; We are two resplendent suns—we it is who balance ourselves, orbic and stellar—we are as two comets; We prowl fang'd and four-footed in the woods—we spring on prey; We are two clouds, forenoons and afternoons, driving overhead; We are seas mingling—we are two of those cheerful waves, rolling over each other, and interwetting each other; We are what the atmosphere is, transparent, receptive, pervious, impervious: We are snow, rain, cold, darkness—we are each product and influence of the globe; We have circled and circled till we have arrived home again—we two have; We have voided all but freedom, and all but our own joy.

我俩，我们被愚弄了这么久我俩，我们被愚弄了这么久，可现在变了，我们迅速逃走，像大自然一样逃走，我们就是大自然，我们离开这里已经很久，但是如今回来了，我们变成植物、树干、树叶、树根和树皮，我们被安置在地里、我们是岩石，我们是橡树，我们并排地生长在林中的空地，我们吃草，我们是野牛群中的两只，如大家一样自然，我们是在海中一起游泳的两条鱼，我们是刺槐的花朵，我们早晚在小巷周围散发香气，我们也是兽类、植物、矿物的粗劣斑点，我们是两只肉食的苍鹰，我们翱翔在高空，俯视下面，我们是两个灿烂的太阳，我们在像星球般平衡着自己，我们是两颗彗星，我们张牙舞爪地在树林巾梭巡，我们向猎物跃进，我们是午前午后在上空奔驰的两朵云，我们是交混的海洋，我们是两个欢乐的浪头，在互相浇泼和连环翻滚，我们是大气、明澈而善于接受，有时能穿透，有时不能，我们是冰雪，雨水，寒冷，黑暗，我们是地球上的每种势力和产品，我们绕了一圈又一圈，最后我们又回到家里，我俩，我们避免了—切，除了自由和我们自己的欢欣。
