    摘要: The present invention provides a glass-ceramic suitable as a material for forming a reflecting mirror substrate. The glass-ceramic has celsian as a primary crystal phase and contains SiO2, Al2O3, BaO, and TiO2 as primary components and at least Li2O as a modification component, wherein the amount of Li2O is within a range of 0.05 to 1.0 wt. %. The glass-ceramic is substantially formed of a crystal phase of celsian alone, that is, the glass-ceramic is substantially free from hexacelsian crystal phase.

    摘要: A combuster (2) of a gas turbine engine (1) is fed with liquid ammonia and that liquid ammonia is burned to drive a turbine (3). Inside the exhaust passage of the gas turbine engine (1), an NOX selective reduction catalyst (9) is arranged. Inside the intake air which flows into the compressor (4), liquid ammonia is fed. This liquid ammonia is used to cool the intake air. The NOX which is contained in the exhaust gas is reduced by the unburned ammonia which is exhausted into the exhaust passage by the NOX selective reduction catalyst (9).
