In contrast, 8-psk modulation implements a linear mode in which a time-varying amplitude is output from the pa as measured by power versus time during the useful part of the burst.
与此相反的是，8 - PS K调制方式实现线性模式，其中在脉冲串的有用部分期间，功率放大器发射的功率幅度随着时间而变化。
GMSK schemes typically transmit in a saturated mode in which transmitted data is output from the pa with a constant amplitude as measured by power versus time during the useful part of the burst.
GMSK方案一般在饱和模式下进行发射，其中在脉冲串的有用部分期间，功率放大器以功率幅度不随时间变化的方式发送数据。
And so I can substitute that in there, and so I get that the power is the derivative of this versus time.
所以我可以代入这里，得到那个功率，是相对时间的衍生物。
But corporate profits as a proportion of GDP fluctuate over time, depending on the bargaining power of capital versus Labour.
但作为GDP组成部分的企业利润会随着时间变化而波动——这取决于劳资之间的谈判力。
