例句與用法
- modelling and motion analysis of space electrodynamic tethered systems
空間電動(dòng)繩系推進(jìn)的動(dòng)力學(xué)建模與分析 - the answer is that the tether system is potentially more efficient, however paradoxical it may appear
答案在于纜索系統(tǒng)的效率可能較高，不管這看來(lái)多麼矛盾。 - in this application, the lorentz force generated by the interaction between the current in the wire and the geomagnetic field produces an electro-dynamic drag leading to a fast orbital decay . in this paper, we make an intensive study of the process of de-orbiting using electro-dynamic tether system . the concrete work includes : firstly, i have studied the basic principle of how to generate the electro-dynamic drag, modeled via accuracy geomagnetism, made a concrete analysis of the de-orbiting duration, the magnitude and direction of electro-dynamic drag under the action of the dipole and accurate geomagnetic models, set up a counterbalance between electro-dynamic torque and gravity gradient torque, emulate the de-orbiting process of spacecraft, and compared the change of six orbital factors and the de-orbiting duration under the action of the dipole and accurate geomagnetic models
