A flight simulation model is established, which is composed of airflow over mountains model, pilot model and flight dynamics model. It is simulated that Boeing 747 aircraft in landing configuration gets through airflow over mountains induced by simple and complexterrain. The simulation results indicate that the main flight safety problems in airflow over mountains are angle of attack increasing and...
The vacuum circuit breaker is used in substations with AT power supply traction, which has advantage properties of frequent operation, maintenance free, long life and low cost of domestic vacuum extinction chamber. The design and manufacture of the switch is autonomous, which passed all type tests firstly with this voltage level for domestic. The parameters of the switch are as follow: rate current...

Synergetics and He-Xie theory have far reaching implications for organization evolvement mechanism, and this article attempts to apply them in this field. It begins with a brief review of Synergetics and He-Xie theory, and then applies the theories to the study of system evolvement mechanism. He and Xie are all likely to turn into the order parameter of a system and they both have the equal chance...
