Based on the analysis of two intercept trajectories of anti-torpedo torpedo(ATT),mathematical models of converse trajectory and direct trajectory were established.

It is very important to research the structural dynamic response of torpedo under the shock of underwater explosion and the damage radius of anti-torpedo torpedo(ATT) for the development of ATT.

It is important for anti-torpedo torpedo(ATT) to estimate the course angle and distance of high speed underwater vehicles so as to enhance the probability of successful interception.

A Preliminary Study of Operational Mode and Intercept Trajectory of ATT;

Electric Propulsion System of Small Diameter ATT;

Research on ATT Guidance Simulation;

By analyzing the problems existed in the cross use of 65 t hot-metal ladle and 320 t torpedo ladle in Jinan Iron & Steel Corporation, measurements on improving the working condition of transportation and maintenance are put forward and the good effect is obtained.

According to the process status of Jigang, three fashions of feeding molten iron for converter by torpedo ladle, by mixer furnace and by iron ladle are compared with, and then torpedo ladle as a fashion of feeding molten iron converter is.
