In this thesis, a vast amount of textual and material records are collected on the Tang Seal script, namely, stelae inscriptions, ink imprints, seal on the inscription frons and seal scription on the cover of the inscription on the tomb This study amasses over five hundred pieces of work of seal on the inscription frons and seal scription on the cover of the inscription on the tomb, spanning all sub-periods and geographic regions of the Tang period.

本文的主体分为五个部分：第一部分，根据书法风格之异同，通过对所搜集的资料进行排比分类，将唐代篆书的发展分为四个时期，分别为：第一阶段在武德、贞观年间是唐代篆书的沿袭期；第二阶段大致从永徽年间到开元之前的探索期；第三阶段大致在开元至贞元之间的高峰期；第四阶段，从贞元直至唐灭的陵夷时期。

The apparatus further includes a quad-symbol mapper which quad-maps the systematic symbol streams to one symbol stream, a channel interleaver which independently interleaves the quad-mapped systematic symbol stream and the parity symbol streams, quad-demaps the quad-mapped systematic symbol stream, interlaces symbols in parity symbol streams, and serial-concatenates the quad-demapped systematic symbol stream to the interlaced parity symbol streams.

该设备还包括：四码元映射器，其将系统码元流四映射到一个码元流；信道交织器，其独立地交织四映射的系统码元流和奇偶码元流，对四映射的系统码元流进行四逆映射，交错奇偶码元流中的码元，并且将四逆映射的系统码元流串行连接为交错的奇偶码元流。

The even-product of quaternions is also not widely used, but it mentioned due to the similarity between it and the odd product.

四元数偶积也不常用，但是它也会被提到，因为它和奇积的相似性。

Pairs of unit quaternions can represent a rotation in

单位四元数的对可以表示

In this example, Quaternions provides a better interpolation type when blending between the keyframe and motion path animation.

在这个例子中将展示，进行混合关键帧动画和移动路径动画时，四元数提供更好的内插种类。

The second argument that is commonly given for the use of quaternions is the possibility of smoothly interpolating between two orientations.

使用四元数的第二个理由，就是其可实现两个状态间的平滑插值。

SINS is calculated by quaternions and the in-tegrated navigation system is simulated by federated Kalman fil-tering method in this paper.

本文采用四元数法进行SINS计算，并运用联邦滤波的方法对组合导航进行了仿真。

What are quaternions?

什么是四元数？

The contents of the first quaternion of Amiatinus coincide so remarkably with descriptions of the celebrated Codex Grandior of Cassiodorus that it has been supposed that the leaves were transferred from it bodily; the conjecture has been rendered more credible by the fact that this codex was actually seen in England by Bede, perhaps before Amiatinus was carried to Rome.

内容的第一次四元的amiatinus不谋而合，所以显描述著名法典grandior的cassiodorus称，它一直以为叶均被转移到它的身体；猜想已变得更为可信的事实，即这一法典，是我们实际上所看到的在英格兰，由贝代，或许之前amiatinus进行了罗马。
