The factors influencing the wellbore temperature in heavy oil production;

In the light of the energy balance equation of vertical conduit flow and combined with the computational method for the Ramy wellbore temperature distribution,the paper gives the distributions of wellbore pressure and temperature when CO2 is injected at different injection rates,injection temperatures and injection time etc.

Effect of barrel temperature on physicochemical properties and texture of reformed rice;

The effect of barrel temperature, screw rotational speed, screws mixing elements and its assembled configuration on the goodness of mixing have been investigated during the processing of twinscrew extruder.

PID controller of barrel temperature based on BP neural network;

Process parameters are settled such as barrel temperature, screw speed, injection pressure, injection velocity and holding time and so on.

Firstly, this paper analyzes the electronic control system of plastic injection-molding machine in detail, puts forward a method which bases on the control algorithm of PID neural network to regulate the barrel temperature, and uses the method to simulate the model of barrel heating system.

, adopts adjusting roller crown, roller temperature and operation sequence to increase the quality of rubberized fabric, makes full use of the fabric, to gain the best benefit.
