转动

Rotation, store the data in the matrix as an axis/angle and do the conversions yourself or will need to convert it to a quaternion.A quaternion is composed of four components: a vector with x, y, z coordinates and a w rotation.

当用一个四元数乘以一个向量时，实际上就是让该向量围绕着这个四元数所描述的旋转轴，转动这个四元数所描述的角度而得到的向量。

This considered the birth of the modern four-wheeled roller skates, which allowed for turns and the ability to skate backwards.

这被视之为是现代四轮旱冰鞋诞生的标志，穿上他能够自由转动方向和倒滑

Its factors of structure,such as moment inertia,friction,gear clearance,will undoubtedly affect the functions of the system.

伺服系统中一些部件的机械参数，如转动惯量、摩擦、齿隙等都会对伺服系统的稳定性、稳定精度及动态性能指标产生重大影响。

She turns them around, the better to look at her fingers from all sides.

婴儿转动他们的手，以便从各方面看她的手指。

Various problems concerning the mass of the lay calculation are discussed as follows:(1) The fundamental equations to calculate the moment of inertia and the mass of the lay.

The implementing agency through the fire damper fusible metal film and the clutch body to control the blade rotation.

防火阀的执行机构是通过金属易熔片和离合器机构来控制叶片的转动。

Brief introductions in the field of GDR studies of pygmy resonance and GDR studies in deformed...

在原于核巨共振方面介绍了矮共振区的GDR研究，形变核的GDR以及高温转动核的GDR研究。

This means that the gear ratio changes as the gear turns, meaning that the output speed also changes.

也就是说，当齿轮转动时，齿轮的传动比是变化的，那就意味着输出速度也会变化。

The gear pump is the volume pump's one kind, by two gears, the pump body and the first top plate is composed two seal spaces, when gear-driven, the gear withdraws the side the space volume to increase since childhood, the vacuum production, inhales the liquid, the gear meshing side's space's volume is small from the big change, but pushes in the liquid in the pipeline.

齿轮泵是容积泵的一种，由两个齿轮、泵体与前后盖组成两个封闭空间，当齿轮转动时，齿轮脱开侧的空间的体积从小变大，形成真空，将液体吸入，齿轮啮合侧的空间的体积从大变小，而将液体挤入管路中去。

The split between the two groups can hardly be papered over.
