Lifting surface method and non-linear vortex lattice method were used for the calculation of propeller and rudder with additional thrust fins respectively.

对螺旋桨与舵附推力鳍分别采用升力面法和非线性涡格法计算。

Such tiny particles combust more rapidly than larger particles to give an additional kick, and may allow easier control over a rocket's thrust.

这样的微小颗粒比大颗粒燃烧的更迅速，从而能提供额外的推进力，并可以更加容易控制火箭的推进。

That would provide the additional thrust necessary to put the spacecraft into a trajectory to reach Mars.

But the May deal, which extended a temporary AMT exemption for one year (to keep an additional 15 million taxpayers from being thrust onto AMT in 2006), left the AMT rules for 2007 unsettled.
