Principle of thwartwise motion in tufting machine, hardware and function of Programmable Multi-Axis Controller (PMAC) and controlling process were presented.

The transverse motion of particle enhances the heat and mass transfer of material in the rotary kiln, and it is important for the optimal design and practical use of the equipment.

In this paper, the influ ences of the transverse motion on the electron back bamardment in SW linacs have been analysed by solving the beam envelope equations under backward moti.

The transverse motion is taken into account and the full 3D motion equations are developed.

So,a cutting angle of PDC cutter under drilling with lateral movement is given a strict definition,the calculating formula of the inclination and cutting edge inclination at any point of blade contour is then deduced and the influencing rule of bit's lateral drilling rate on a cutting angle.

The coefficients and the first order rolling moment in the first order rolling motion equation and the rolling response function per unit wave front angle are obtained.

The rolling motion of an unstabilized ship and a stabilized ship equipped with fin stabilizers has been predicted by use of a random wave model.

According to the condition as mentioned above,a typical linear roll motion equation was set up, and the expressions of natural angular frequency and nondimension damping decay modulus of amphibious combat weapon were given.

It is well know that roll motion of amphibious combat weapon in regular wave will severely affect the battle effectiveness of crew in the amphibious combat weapon and the fire accuracy.

The method used to simulate ship roll motion by the equipment was analyzed.
