sink rate

this sink rate will kill me. i've got to get the sink rate under control first.

这么快的下降速度会要了我的命，我首先必须控制下降速度。

his plane was still falling fast, even after he managed to decrease the sink rate.

尽管他已降低了飞机的下降速度，可飞机仍在迅速俯冲。

sink-rate changes dramatically with pilot weight and it is not possible to have one parachute for all pilots.

下沉率跟体重的关系很大，不可能用同一大小的备份伞满足所有的飞行员。

We use a soft stop detent to indicate the desired touchdown sink rate in the STOVL mode.

我们用一个软着陆闭锁装置来标明垂直起降模式下所需要的着陆下沉速率。

The growth rate of the metallic compounds, as afunction of sink-densities, dose-rate and thermal emission-rates, is obtained.

得到了生长速率与微缺密度、注量率、热发射率之间的定量关系。

the linear optimal control theory is used for the optimal control law ( elevator control, column angular displacement and throttle angular displacement) during landing that will enable an aircraft to get a safe landing and achieve the smallest possible longitudinal dispersion and sink rate deviation.

本文用线性控制系统的最佳理论求解飞机在着陆拉平过程中的最佳控制规律（包括升降舵操纵杆和油门杆角位移控制），使飞机安全着陆且纵向偏离和下沉率偏离最小。
