The Angle increases, 2 so in our case from t1 to t2 0 the average acceleration is larger than zero Look at the Angle.
角度在时刻t1到t2的过程中,增加了2,故平均加速度大于,看看这个角度。
The simple r-g assumption is one of the most important in debt dynamics: an r-g of greater than zero (when interest rates are greater than GDP growth) means that the debt stock increases over time.
简单的对(r-g)的假设是债务动态中最重要的部分之一。
Especially, the process that the static instability mode transforms into the dynamic instability mode is simulated as the dynamic characteristic parameter increases to a certain value from zero.
特别分析了随着动力特征参数由零增加到一定值后,由静力失稳模态过渡到动力失稳模态的过程。
