查询词典 centre of mass

But, unlike the black hole at the centre of our Milky Way, the million-solar-mass black hole inside NGC 4945 is an Active Galactic Nucleus that is frantically consuming any surrounding matter, and so releasing tremendous amounts of energy.

但与银河系核心的黑洞不同，NGC 4945中数百万太阳质量的超级黑洞正在疯狂地吞噬周围的物质、并释放极为巨大的能量——是个活跃星系核。

We can assume all the mass of the body to be concentrated at its centre of gravity .

我们可以假定物体的质量全部集中在重心上。

He identifies himself with its centre of gravity, its mass, its weight.

他把自己与形体的重心、质量、重量联系在一起。

In this paper,the influences of the location of mass centre on the moving stability of a motorcycle has been studied by way of establishing a mechanical model,and further,a general principle has been proposed to locate the mass centre in design of motorcycle s.

本文通过建立摩托车动态力学模型，分析了质心位置对车辆稳定性的影响，提出了质心位置设计的一般原则。

Due to total angular momentum conservation about the system centre of mass, a torque-free spacecraft system with space manipulators becomes the nonholonomic control system.

自由漂浮空间机械臂系统在无外力矩作用时，系统的动量矩守恒而成为非完整系统。

The situation after the first M step is shown in plot, in which the mean of the blue Gaussian has moved to the mean of the data set, weighted by the probabilities of each data point belonging to the blue cluster, in other words it has moved to the centre of mass of the blue ink. Similarly, the covariance of the blue Gaussian is set equal to the covariance of the blue ink.

图显示了初始的 E 步骤，用红色表示用红色 component 产生的后验概率，蓝色也是同样的情况，还有一些不太确定的点是用紫色显示的，在图中蓝色的高斯的均值已经移到了蓝色数据集的中心上，类似的，蓝色高斯的协方差设为蓝色点的协方差。

Due to the total angular momentum conservation to the system centre of mass, the free-drifting spacecraft system becomes a nonholonomic one without considering the external forces moment acting on it.

空间自由漂浮的航天器系统在忽略外力矩的作用时，系统因对总质心的角动量矩守恒而成为非完整系统。

Reinhard Genzel obtained compelling evidence for this conjecture by developing state-of-the-art astronomical instruments and carrying out a persistent programme of observing our Galactic Centre for many years, which ultimately led to the discovery of a black hole with a mass a few million times that of the Sun, in the centre of the Milky Way.

莱因哈德E根舍对这个挑战性的猜测，找到了证据。他发展了最先进的天文设备，并持之以琣a对银河系中心进行长达数年的观测，终於笫一个获得确切证据，发现在银河系中心有一个黑洞，其质量是太阳质量的数百万倍。

In this paper, coordinate and momentum eigenstates of two-particle have been introduced in the centre-of-mass system. New formalisms of two-mode squeeze operator and two-mode squeezed state have been given in coordinate and momentum pictures.
