Analysis of the Influences of Temperature Difference Load on the Central Tube Failure Damage of an Ammonia Converter;

The firing process for the central tube bursting－type shrapnel involvesboth the process of powder burning and that of bullet dispersion.

In this paper,through the CFD modeling of the ash-agglomerated fluidized bed gasifier,the gas molar concentration distributions in the bed with the influences of the oxygen flow rate from the central nozzle,the steam flow rate from the distributor and the pressure of the bed are studied.

To protect biological safety of China an informatized network-based high-throughput and real-time biological safety detection system is designed which is composed of terminal labs, online gene detection section and a management center.

This paer expounds the necessity and urgency of developing collaborative design from the point of enterprise competition,and points out the significance of developing he management center for collaborative design to the collaborative desing.

Management center should seize the opportunity to form innovative thought and promote development and prosperity: concentrating on planning,focusing on technology development,increasing the intensity of training,strengthening cooperation and raising awareness of service.
