This article was about the determination of the same sample's absorbent on the condition of different solution temperature, different still time and different water bath temperature,From it we could prove that the result was relative to different experiment conditions.

Soft-sensing model of copper liquid temperature in copper refining process and its application;

Soft-sensing model for copper liquid temperature of heat preservation phase in copper refining rotary anode furnace and its application;

By optimizing the technological regulation,importing real-time monitoring,strengthening the management,the molten steel temperature stability can be assured and the breakout rat.

A neural network prediction system of molten steel temperature for VD has been developed.

The prediction model of molten steel temperature for LF VD CC route has been developed by means of meural network method The difference between the predicted and measured temperature was in range of 0 7 ℃ for 85 % heats,and less than 10 ℃ for all heats Because of data replacement function in the model,the prediction precision can be guaranteed regardless of the influence of gradual change factor

This paper briefly calculates the outlet pressure of high pressure ammonia pump and thecurrent of electromotor under different liquid ammonia temperature,and calculates the saving of pumpsealing and electromotor after increasing the inlet temperature of liquid ammonia.
