Aluminum gallium indium nitride quaternary epilayers were prepared by metalorganic chemical vapor deposition on c -plane sapphire （α-Al2O3） substrates.

利用金属有机物化学气相沉积方法在 c 面蓝宝石（α-Al2O3）衬底上外延生长了铝镓铟氮四元合金薄膜。

After the data collection finished, it send to the PC through RS232 serial port. It gets the relatively high acceleration of the equipment, basing on the quaternion equation of the mathematics platform, and through the calculation of the angle changing and the acceleration sensor send-out.

采集工作完成后通过单片机串口发送至PC机，在基于四元数方程的数学平台中，通过对角度变化及加速度传感器输出量的换算，求得装置相对大地的加速度。

In this paper, some results of the self-conjugate matrices over skew-field of quaternions are given.

本文在[l—5]基础上，给出四元数自共轭矩阵若干结果。

A conclusion that the symmetric product of a self-conjugate matrix is still a self-conjugate matrix was obtained.

给出实四元数体上矩阵对称积的定义，得到了自共轭矩阵的对称积仍是自共轭矩阵的结论。

In terms of the fact that Skinned Mesh Animations based on Matrix palette skinning does not work well for non-quasi-articulated objects, this paper presents a new technology for skin deformation, skinning arbitrary deformation,which can set proxy-joints,automatically construct skinning approximations for arbitrary precomputed animations,and use dual quaternion for skinning .

针对利用MPS驱动的骨骼蒙皮动画对于非关节的对象精度不高的问题，提出了基于MPS的任意变蒙皮，该技术在任意动画上设置代理关节，自动为预先处理的任意动画的每一帧构建蒙皮相似量，利用二重四元数蒙皮，实验表明，SAD不仅能够有效地驱动非关节元素对象提高精度，而且能够充分利用MPS的优点

Except for one thing: you don\'t have a good reason to use quaternions yet.

但除了一件事情，你还没有明白为何要使用四元数的原因。

The concept of Quaternions should be clearly understood.

在四元数的概念应该明确的理解。

Before discussing why you would want to use quaternions, there\'s one more thing that needs to be explained.

在讨论你为什么要使用四元数之前，还有最后一个需要解决的问题。

You pretty much know all the important stuff about quaternions now.

你现在几乎获得了所有关于四元数的重要信息。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
