So it is this component, v cosine theta - which we call the radial velocity-- that is minus 100 kilometers per second.
这个成分，是vcosθ,我们叫做径向速度-,等于-100，公里每秒。
I am going to decompose them, so I have one component here and this component equals mg times the cosine of alpha.
分解重力，这里得到一个分量,这个分量等于mgcosα
Then this is the component in your direction we call that the radial component which is v cosine theta.
这是y方向的，组成因素,我们称之为辐射组成,等于vcosθ
So this one equals m1 g cosine alpha - and this one, the x component-- which is in the minus x direction now-- equals m1 g sine alpha.
得到m1gcosα,而x方向上-,这里是x负方向-,大小是m1gsinα
This paper presents the Cosine algorithm that can best restrain DC component for amplitude attenuation.
提出一种能很好抑制幅值衰减的直流分量的余弦算法。
As the amplifier tuned load circuit, they are able to select the base component cosine pulse to obtain undistorted amplification signal output, so this amp is also known as tuned power amplifier.
由于放大器的负载为调谐回路，所以能选出余弦脉冲中的基准分量，获得不失真的放大信号输出，因此这种放大器也称为调谐功率放大器。
