物体轴线

Object positioning is based on local normal of a polygon or vertex in destination object and world up axis.

物体的位置是基于目标物体表面的顶点和面的自身法线和世界空间向上的轴线确定的。

AXIS, An imaginary straight line or an actual physical component around which a body can rotate.

轴线， 可让物体围绕着作旋转运动的一个想像的直线或实际存在的部件。

You have to construct your object with a lot of control points so that it will taper properly.

在递减轴的端点的提示下，在你想让物体变窄的范围内挑选轴线的第二点。

The device comprises: a conveyer belt; a let-off roller (16) on which the conveyer belt runs and from which the rubber tape is let off; a traverser (21) to move the let-off roller (16) in an X-axis direction parallel to the rotational axis of the object; a radial shifter to move the let-off roller in a Y-axis direction perpendicular to the X-axis direction; a tilter (23) to turn the rotational axis of the let-off roller (16) around a reference axis which is parallel to a Z-axis direction perpendicular to the X-axis direction and Y-axis direction.

所述装置包括：输送带；送出辊，所述输送带在送出辊上行进并且所述橡胶带从送出辊送出；移动台，其沿平行于物体的旋转轴线的X轴方向移动送出辊；径向移位装置，其沿垂直于X轴方向的Y轴方向移动送出辊；倾转装置，用于绕平行于Z轴方向的基准轴线转动送出辊的旋转轴线，所述Z轴方向垂直于X轴方向和Y轴方向。

Although these combined relative error γ.1%, in order to obtain more precise measurement results, it should be pay attention for the level of the torsion pendulum, the uprightness between the photoelectric doors and the block rod, the location of the being measured substance, the similarity of the shape and the quality between the standard object and the being measured object, human factors and so on.

利用扭摆法测量物体的转动惯量，受到待测物体摆动周期测量误差、装配位置偏移误差和轴线倾斜误差的影响，虽然这些相对误差总合γ。1%，为了使测量结果是加精确，实践中应该注意扭摆的水平、光电门与挡光杆的垂直、待测物重心的位置、人为误差的影响以及待测物与标准件形状、质量的相近性等。

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

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
