As the system's "software bus", CORBA connects the stage of flight simulation modeling environment and the long-distance model warehouse and algorithms library.

CORBA作为系统的“软总线”把飞行仿真建模环境的前台和远程的模型库和算法库连接起来。

The theory of stages of education is to train flight attendants in the basic stage, is also the starting point of the Civil Aviation College Students stage of flight attendants.

理论教育阶段是培养空中乘务员的基础阶段，也是民航空乘大学生成才的起点阶段。

NASA needs good weather to launch Ares I-X because engineers need to see the rocket flight all the way through first stage separation, which will mark the end of the test.

NASA需要好天气来发射战神I-X，因为工程师们要在第一级火箭分离前观测火箭飞行全过程，第一级火箭分离标志着试飞的结束。

It's specifically designed to shoot down missiles during their final stage of flight, and is expected to arrive on Guam within the next few weeks.

And, similar to Dyson, Lugg is proposing to achieve these radical efficiencies by coordinating multiple engine systems (analogous to the acceleration, inducement and entrainment of the Air Multiplier) to create optimal conditions for each stage of flight and to use the excess energy the system produces to create a plasma field to reduce drag and eliminate sonic boom.

It will use a balloon to carry its rocket on the first stage of its flight.
