On average the region experienced an acceleration of growth to 2.7 percent from 2.1 percent in 1999, and per capita incomes stabilized following two years of decline.
该地区的平均增速从1999年的2.1%提高至2.7%，人均收入也在连续两年下降之后趋向稳定。

And, finally, following this equation, a simple graphical method has also been proposed in this paper to determine the critical rapping acceleration.
由此计算式给出了一种确定临界振打加速度的简易图解法。

So, variable structure control theory is used in Angle stabilization of roll, and model - following variable structure control theory is used in acceleration stabilization of pitch and yaw.
