释义 | propulsion noun[ U ] uk /prəˈpʌl.ʃən/ us /prəˈpʌl.ʃən/ a force that pushes something forward: 推进;推动力 wind propulsion风力推进 a propulsion system推进系统 See also jet propulsion Physics: energy, force & power animal magnetism anti-gravity attract attraction ballistic entropic entropically equilibrant erg excited geothermal inertia jet propulsion preatomic propulsive radiant energy self-propulsion sine curve the sound barrier thermodynamics propulsion | American Dictionarypropulsion noun[ U ] us/prəˈpʌl·ʃən/ the force produced by a system for moving a vehicle or other object: jet propulsion Examples of propulsionpropulsion Only with the high exit velocities possible with pulsed laser ablation propulsion is it possible to overcome this problem. The gradient in muscle tension created along the intestine (increased in jejunum and decreased in ileum) may promote propulsion of worms in the lumen. Propulsion obtains the dimensions it requires from hull, determines the ver tical center of gravity for stability, and provides total thrust to resistance. This hopper included a translational offset mass in order to cause the tipping action that helped in forward propulsion. This is a useful generalized account, serving as an introduction to the short discussion of hypersonic propulsion that is given later. Also, carangiform propulsion is more convenient for engineering realization. Calculated efficiencies are found to be insufficient for propulsion applications that require short periods of acceleration but ion-beam propulsion shows some potential for prolonged flights. Here, the selective pressures for efficient maintenance of high-speed propulsion appear to be responsible for the convergent evolution of caudal fins of high aspect ratio. It also includes fault-tolerant control of a chemical process, and of a ship propulsion system, and of a steam generator. They are of interest because they may represent the first economically viable application of laser ablation propulsion. Here, we do not want the extraction short hairs = cilia propulsion. Advancements in computer and control technologies have, in this case, enabled propulsion by delicately controlling elastic fins on the fish. This subject has been carefully and continuously studied ever since jet propulsion became technologically feasible. Such a control strategy allows us to influence forward propulsion to assure constant gait velocity. In addition, it provides a method of generating plasma magnetospheres for laboratory simulation of astrophysical studies and space propulsion.
