Angles are measured clockwise when looking along the rotation axis toward the origin 角度按照沿旋转轴向原点方向看的顺时针方向测量。
Material along the rotation axis falls vertically toward the equatorial plane much faster 沿著转轴两侧分布的物质则快速笔直地落入赤道面。
Angles are measured clockwise when viewed from the rotation axis positive side toward the origin 角度按照沿旋转轴(正面)向原点方向看的顺时针方向测量。
Place the 3dcursor at the position through which the rotation axis must pass . such an axis will be vertical 放置3d光标在你要作为旋转轴的位置,轴是垂直的。
When swinging transmission machine operation , the force constant rotation axis to make efforts before and axial rotation move backward 当摇摆传动机械运行时,等速旋转入力轴使出力轴向前和向后旋动。
For those who haven ' t heard the word , " precession " is when an object with a nonspherical shape wobbles around its rotation axis 如果你还不了解“进动”这个词,进动指的是物体绕它的旋转轴有非球形的摆动。
Precessing stars do radiate gravitational waves , but they ' re not the only ones . any asymmetry about the rotation axis will do 进动的星体确实会辐射引力波,但它们并非唯一的选择。绕旋转轴的任何不对称都会导致引力波的产生。
As the earth spins on its rotation axis , it wobbles like a top , slowly swinging the northern hemisphere closer to and then farther from the sun 当地球自转时,自转轴会像陀螺一样晃动,因此北半球与太阳的距离会逐渐接近,继而远离。
Material in the equatorial region of the cloud ? that is , in the plane perpendicular to the rotation axis ? moves inward more and more slowly as rotation starts to balance the pull of gravity 当转动开始与重力的向内拉力平衡时,位在整团云气的赤道区域,垂直于转轴的平面上的物质,会逐渐减缓向内移动的速率。
Made in the rotation axis , dividing machinery to stop transmission . at this point , the operator may decide indexing products position , and began fabrication , assembly and testing needed for its action 在出力轴旋转后,分度传动机械停止。此时,操作者可决定分度产品的位置,并开始加工、装配和检验,作其需要之动作。
