rotation axis

基本解釋

The key point for re-constructing rotation surface is setting up rotation axis and generatrix.
旋轉(zhuǎn)面重建的關(guān)鍵是確定旋轉(zhuǎn)軸和母線。
Positive values for the angle rotate the object clockwise if you look along the positive rotation axis.
角度為正值，則表示若您順著正旋轉(zhuǎn)軸方向觀察，對(duì)象是按順時(shí)針旋轉(zhuǎn)的。
The paper proposes a new method of using the ultrasonic-speed turbine as a power sourse and using the magnetic suspension bearing as the main back-up bearing for the rotation axis.
本文提出用永磁材料制作的永磁懸浮軸承作高速旋轉(zhuǎn)軸的主要支承，軸流式超音渦轉(zhuǎn)作回轉(zhuǎn)軸的驅(qū)動(dòng)動(dòng)力源。

So it's very important to be keeping in mind that any time you see a double bond, you have a pi bond there, so you're not going to see any rotation around the bond axis.
所以你們要記住,任何時(shí)候你們看到一個(gè)雙鍵，這里面有π鍵，你們不會(huì)看到關(guān)于鍵軸的任何轉(zhuǎn)動(dòng)。

Based on the Phoenix lander, the craft is tasked with giving us a peek beneath the planet's surface, armed with tools that include a geodetic instrument from the Jet Propulsion Laboratory, which will be used to calculate Mars' rotation axis, a seismic wave sensor and a subsurface heat probe, to measure the planet's internal temperature.

Because Jupiter's axis of rotation does not quite line up with its magnetic axis, the moons that orbit the planet feel such a fluctuating magnetic force.

Today motion sensing has progressed to being three-axes of acceleration, and three axis of rotation (technically called gyroscopes).
