Reconstruction has been made on an eccentric plier which is the only such machine of Russian made in the 1950s still remaining in China by computer control of which the model for speed tracker algorithm and dynamic correction is presented in the paper.

the aim-ing error in practical launching missiles, and thinking over the dynamic correction of thetarget s maneuvering movement in the course of guidance, the important conclusion aboutguiding the correct designing and using proportional guid.

The main causes of the dynamic error occurred in the weighing process are analysed,and an improved method based on dynamic correction and second-order prediction is proposed to reduce the influence on the data of preact.

In ERP/MRP-II system, dynamic leading time is a variable closely related to delivery time, inventory plan and capacity balance plan, etc.
