In 2003, the most severe heatwave in living memory broke temperature records by a large margin and caused 70,000 deaths in Europe.
2003年，人们记忆中最严重的热浪大幅度打破了气温纪录，导致欧洲70,000人死亡。
The margin of temperature rising is very small. As a result, the welding traces on product surfaces can be alleviated rather than removed thoroughly.
升温幅度较小，制品表面的溶接痕只能得到减轻而无法消除。
Therefore, the margin of the maximum gas temperature, rotor speed and capability of HP compressor are required during the development of core engine and baseline aero-engine.
因此，在核心机及基本发动机研制中，既要有燃气温度和转速的储备，又要有高压压气机性能的储备。
