aThe electric force is a constant value applied for 90% of the stroke, but not at the turning points when piston speed is low. An estimation of the friction force can be deduced from the friction mean effective pressure, fmep. 当活塞速度是低的时,电力是90%申请恒定的价值冲程,但不在转折点...

After adding a driving force and solving the nonhomogeneous system, resonance is illustrated by choosing the frequency of the driving force to be close to a natural frequency. The model of Leslie is a heavily used tool in population ecology. It models an age-structured population which predicts...
The electric field strength at a point near a point charge is the magnitude of the electric force experienced by a unit test charge at that point. The electric field strength depends on the magnitude of the point charge and the distance of the point from the point cha...
