The Bernese 5.0 software is used to compute the precise orbits of the FORMOSAT-3 and GRACE satellites using the kinematic and reduced-dynamic methods based on zero-differenced GPS phases from these two satellites missions. This study concentrates on the effects of satellite attitude, GPS antenna phase center variation and center of mass.

Why is the Moon's center of mass off center?

为什么月球的质心不再月球的中心？

A center of symmetry must coincide with the center of mass.

对称中心必须与质量中心重合。

Due to the effect of torsional vibration arose by eccentricity of the center of mass and the center of rigidity, there will produce stress concentricity in some local location of the structure, which is very detrimentally. This paper discussed the contribution of the reduction of the response of torsional vibration of the accessorial eccentrically braces in structure on emphasis.

由于不规则高层建筑的质心刚心偏心而引起的扭转振动效应，会使结构的局部产生应力集中等极为不利的情况，因而本文着重讨论了增设偏心支撑后的结构，对减小原结构的扭转振动效应的贡献。

Photofragment translational spectroscopy is an ideal tool to investigate photodissociation dynamics under collision-free conditions through which one can obtain the total center of mass translational distribution, angular distribution, and the branching ratios for different possible product channels by measuring the angle-resolved time of flight spectra of photofragments. Information about photodissociation processes such as dissociative lifetime of parent molecule, the orientation of transition dipole moment, and the symmetry change of the highly excited states can be deduced from the translational energy distribution and angular distribution.

碎片平动能谱方法是在无碰撞条件下研究光解动力学的一种理想方法，它通过测量光致碎片在不同角度的时间飞渡谱(Time of Flight，简称TOF)，可以得到光解碎片质心系的平动能分布、角分布和不同解离通道之间的分支比等，由此可以推知母分子的解离寿命、跃迁偶极距的取向以及激发态分子的对称性变化等过渡态的动力学信息。
