While machining turbine blade simply by Parallel machine Tool (PMT), NC program development is often limited by workspace of PMT, and it is difficult to process at the best posture.

用并联机床加工汽轮机叶片时，往往受其工作空间的限制而不能在最佳的切削姿态下进行加工。

To counter the difficulty of traditional method, the parallel connection feed-forward network of calculation method for the actual cycle thermal efficiency of a steam turbine is proposed.

针对传统方法计算繁杂的问题，本文提出了基于双并联人工神经网络的汽轮机实际循环热效率计算方法。

The axis of a flame tube being parallel to that of an engine, the flame crossover tube of a turbine combustor is usually orthogonal with respect to the flame tube.

由于火焰筒轴线平行于发动机轴线，燃气轮机燃烧室的联焰管与火焰筒正交。
