center of mass什么意思,center of mass翻译

基本解释

un.: 质量中心；质心
网络: 质心系

英汉解释

• 质心

• 质量中心

例句

• As another example the center of mass of the earth and moon moves in an approximately circular orbit around the sun.

  作为另一个例子，地球和月亮的质心就是在一个绕太阳的近似的圆轨道上运行。

• But one that you might have seen in physics, we care about maybe where is the center of mass of a given object?

  但你们可能也在物理学中见过了，就是求一个给定物体的重心？

• The center of mass of a system is defined as follows: I have here some kind of an object not just a point mass, but it has a finite size.

  系统的重心，是这样定义的：，我有一个物体，不是有棱角的物体，但它大小有限。

• Since the stars are orbiting around the center of mass of the binary, the visible one will move in a wavy line.

  由于双星会绕著共同质心运行，所以假若某星有隐形伴侣，它便会以波浪形而非一般的直线运行。

• In the case of the center of mass, 0 the total momentum is always zero.

  在质量重心体系中，总动量总是为。

• What I can do now, I can suspend it like this, and I know that the center of mass must be below my finger. Did you notice?

  我现在能做的，我可以这么悬挂它，我知道重心，肯定在我手指下，看到了吗？

• The King"s Chamber is not the center of mass of the Great Pyramid, rather it is where the primary energetic vortex is centered.

  国王的墓室并不是大金字塔的质量中心，而是最初的能量漩涡的中心。

• But the basic idea is, then, that the center of mass will always in stable configuration line itself up below the point of suspension.

  但是基本概念是，物体的重心将一直，处于稳定的结构线上，在悬挂点下面。

• In the case of a completely inelastic collision, there is no kinetic energy left in the center-of-mass frame.

  在完全非弹性碰撞中，没有动能剩余，在质量重心体系中。

• High hydrophobicity and an imbalance between the center of mass and the barycenter of its hydrophobic regions decreased the activity.

  高疏水性以及质量中心与疏水区中心的高不平衡性对活性是不利因素。
