Introducing the effctive POtential, the two -- dimensional central force mation in the potential field for the inertial system can be handled by means of the one -- dimensional central force motion for the non -- inertial system, because they are equivalent.

Through the method of curve fitting, the eccentric motion which is of the same frequency as the rotary speed is separated (effectively ) from the signals in the first harmonic component.

Simulation in computer and experimental analysis of hobbing process in the case of motion eccentric;

This paper gives a minute analysis on the motion eccentric produced in hobbing with the method of instantaneous pitch point of gear meshing theory The conclusions prove that it is very convenient and accurate to analysize machining errors of gear with this metho

Study on the expression and effect of small heat shock protein in skeletal muscle after eccentric exercise training

70kg)were recruited for eccentric exercise and endurance exercise.

Through analyzing the change of CK,the low threshold of subjective ache senses and touch-tallness of upright jump between PNF group and control group in separate period of 24h,48h,72h after eccentric exercise and quiet state before.
