转动

This method can be used to simulate the scattering feature of rotating, vibrating and nonrigid moving object.

应用该方法可以模拟转动、颤动以及非刚体运动目标的电磁散射特性。

Planar motion also requires that axes of all prismatic pairs and all revolute axes be normal to the plane motion.

平面运动需要所有的棱形副的轴和转动副的轴都垂直于运动平面。

Her main scientific interests are comparative planetary interiors and rotation, as well as modeling tides and nutation of the Earth, Mars, Mercury and Venus.

她的主要研究专长在于各行星的内部结构和自转的比较。亦精于地球、火星、水星和金星的潮汐作用和地轴的转动的计算。

It's not the end of the world. Just like Scarlett O'Hara said,"Tomorrow is another day."

地球不会因此而停止转动，就像郝思嘉说的，"明天又是新的开始。"

Axis of maximum moment of inertia = the axis of figure: because the Earth is not a perfect sphere, but is physically an oblate spheroid, the position of the axis of figure is not a precise constant, but is affected by the constant change in the earth's distribution of total mass:(ie, by ocean tides, atmospheric cond- itions, plate tectonic movements, etc.).

轴最大转动惯量=形状轴：因为地球不是完全的球形，而是一个扁球体，形状轴的位置不是精确的常量，而是受地球总质量的分配持续变化作用：（也就是，受海洋潮汐、大气环流、地质板快运动等等）。

A self-drilling anchor (10) for use in a friable material (1) comprises a body (12) having an axis (13), a flanged rear end (14), a drilling front end (16) and a generally cylindrical portion (18) therebetween having an outer surface (20) with a thread (22) disposed thereon, wherein the body forks, beginning at a predetermined distance from the flanged rear end, into a first leg (24) and a second leg (26), the first leg extending forwardly into a drilling tip (28) and having a generally rearward facing shoulder (30) angled obtusely outwardly with respect to the axis, wherein the body (12) has an axial bore (32) for receiving an elongate fastener (2), the axial bore (32) extending substantially through the flanged end (14) and the generally cylindrical portion (18) and leading to the generally rearward facing shoulder (30), wherein the anchor (10) has a drilling mode wherein the second leg (26) nests behind the generally rearward facing shoulder (30) of the first leg (24), and an anchoring mode wherein the legs are pivoted apart from one another.

一种用于易碎材料(1)中的自攻螺钉(10)，包括：主体(12)，其具有中心轴(13)、带有凸缘的后端部(14)、用于钻孔的前端部(16)和位于所述后端部和前端部之间的通常为圆柱状的部分(18)，所述圆柱状部分(18)的外表面(20)上布置有螺纹(22)，其中主体从距离带有凸缘的后端部的预定的距离处开始分叉为第一腿(24)和第二腿(26)，第一腿向前伸入钻孔尖端(28)，并且具有相对于中心轴向外成钝角的通常面向后的肩部(30)，主体(12)具有容纳细长状紧固件(2)的轴向孔(32)，轴向孔(32)基本延伸穿过带有凸缘的端部(14)和通常为圆柱状的部分(18)，并且通向通常面向后的肩部(30)，螺钉(10)具有钻孔状态和固定状态，在钻孔状态，第二腿(26)套在第一腿(24)的通常面向后的肩部(30)之后，并且在固定状态，腿彼此转动分离。

Lights its sleek design and modeling odalisque vivid, light as an executive light odalisque kneeling seat, left hand holding Medallions, right arm cuffs drooping into the shade, Lamp short-throw hand turn, and plates have shade can be opened and closed as needed adjust brightness and illumination direction.

灯的设计精巧，宫女造型生动，灯身为一跪座执灯的宫女，左手执灯盘，右臂袖口下垂成灯罩，灯盘短柄手转动，盘上有灯罩可以开合，可根据需要调节亮度及照射方向。

Think of each other when your watch goes off, and

当你的表在转动的时候，让思念彼

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。
