The correspo nding learning algorithm is given and the network is compared with three layers feedforward process neural network (PNN) by predicting the exhaust gas temperatu re (EGT).

Since the developed conductor has large temperature margin, it allows relatively higher temperature gradients in the heavy electrical insulation.

Strains towards the lower temperature margin in mid-temperature range can also be used.

The displayed colour is red at the low temperature margin of the colour-play interval and blue at the high end.

The temperature margin in case of transient heat deposition is about 1.4 K at nominal field.

Transient stability experiments of CICC including segregated copper strands have been carried out in the sultan test facility. Samples are heated inductively at pulse field zone (390mm) by pulse field. It is found that CICCs including segregated copper strands can withstand a great field transient. This paper explains this case and investigates the influence of operating temperature on the stability of CICC. Difference of the stability of three CICC conductors is investigated. Stability margin is calculated...

Transient stability experiments of CICC including segregated copper strands have been carried out in the sultan test facility. Samples are heated inductively at pulse field zone (390mm) by pulse field. It is found that CICCs including segregated copper strands can withstand a great field transient. This paper explains this case and investigates the influence of operating temperature on the stability of CICC. Difference of the stability of three CICC conductors is investigated. Stability margin is calculated theoretically and theoretical results are compared with experimental results. Experimental proof is given for the choice of HT-7U TF and PF CICC.

Briefly introduces some fundamental experiences of design and development of the "Kunlun" two-spool afterburning turbojet engine,which was successfully self-designed and developed in China.The design,development and test were strictly followed out the "General Specification of Turbojet and Turbofan Aero-Engines".The adequate proportion between creativeness and inheritance was controlled to reduce risk without sacrificing the engine's advanced status.The design regarded the operability,reliability,durability...

T OKAM AK核聚变装置要实现稳态运行,需要靠超导磁体及导体的稳定性,而C ICC(C AB LE-IN-CONDU IT CONDUCTOR)导体是低温超导磁体的首选磁体,因此需要研究C ICC在大电流和快速变化磁场环境下的低温稳定性.针对这一目的,首先研究了C ICC的稳定性机理,并对铌三锡超和铌钛超导材料给出经验设计公式;然后编程对分流温度、温度裕度、能量裕度进行计算,接着模拟出随运行电流变化的稳定性曲线,并把结果保存到数据库.同时对工程设计值和模拟分析及计算结果进行比较和分析,二者基本吻合.显然,这为C ICC设计提供了极大的方便.
