查询词典 nutations

The authors find coupling mechanism of momentum of nutations between solar and earth. It is caused by solar radiation, earth's rotation and revolution, angle between ecliptic and equator, irregularity of oceans and continents between northen hemisphere and southen hemisphere and layer structure of earth's core.

作者发现：太阳辐射，地球自转与公转，黄、赤交角的存在，陆地和海洋在地球表面南、北半球的不规则、不对称地理分布，及地球内部因〖ZZ〗形成的分层结构，构成了一套天然的能使地球产生自由章动的日、地间动量相耦合的物理机制。

The theoretical nutations of a non-rigid Earth are computed from a convolution of the rigid Earth nutation amplitude with a transfer function accounting for the geophysical parameters influencing the Earth rotation. The value of the Earth dynamical flattening correspounds to a scale in the rigid Earth nutation series.

在刚体地球章动振幅的计算中，地球动力学扁率值起着尺度因子的作用，要改善刚体地球章动振幅的计算，需要修改目前的黄经总岁差值。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。
