四元数

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。

Aim To check and analyze the developmental process from quaternions to vector.

目的考察和分析从四元数到向量的发展历程。

Of course, you\'ll also need to be able to convert from \"conventional\" representations to quaternions.

当然，你可能也会用到四元数转换的&常规&表示法。

The criterion of equality of two quaternions is that their scalar parts shall be equal.

两个四元数相等的准则是，它们的数量部分相等。

However, it was later discovered that quaternions can also be used in computer graphics, as an alternative and compact way to represent rotations.

然而，人们发现四元数也可以应用在计算机图形学上，作为表现旋转的可选择方法之一。

Vector is a useless survival, or offshoot from quaternions, and has never been of the slightest use to any creature.

向量是无用的幸存物或四元数的无价值的支流，对任何创造，从未有过最微细的应用。

Quaternions are a relative of complex numbers .

四元数是与复数类似的一种数。

To combine two rotations, you can multiply two quaternions.

组合两个旋转，你可用两个四元数相乘。

Vector is a useless survival, or offshoot from quaternions.

向量是无用的幸存物或四元数的无价值的支流。

The attitude kinematics and dynamics are both described by error quaternions.

姿态运动学和动力学用误差四元数描述。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
