    • The invention offers a superconducting coil that has the shape of a pancake formed by winding a superconducting conductor. The superconducting conductor is composed of a tape-shaped (Bi, Pb)2223-based superconducting wire and a tape-shaped thin-film RE123-based superconducting wire that are electrically connected in parallel with each other. The coil generates only a low voltage in the steady-operation state, limits the generated voltage to a low level even in a state where an external disturbance enters for some reason, and is therefore less susceptible to quenching. Consequently, the coil can be operated stably in both states. The invention also offers a superconducting conductor to be used to form the coil.
    • 本发明提供一种超导线圈,其具有通过缠绕超导导体形成的薄饼形状。 超导导体由彼此并联电连接的带状(Bi,Pb)2223基超导线和带状薄膜RE123基超导线构成。 线圈在稳定运行状态下仅产生低电压,即使在由于某种原因导致外部干扰进入的状态下也将发电电压限制在低电平,因此不易于淬火。 因此,能够以两种状态稳定地操作线圈。 本发明还提供一种用于形成线圈的超导导体。

    • The present invention is intended to provide a method for assessing remaining lifespan of a bolt with higher precision than conventional methods, which can be applied to a bolt comprising a high alloy with fewer tissue changes caused by creep damage.The present invention provides a method for assessing the remaining lifespan of a bolt used at high temperatures, including: carrying out a creep test for a bolt material that constitutes a bolt to be assessed and determining a life-time and a life-elongation rate; determining a time-temperature parameter based on the life-time and the creep test temperature; creating a lifespan-assessment diagram by plotting the time-temperature parameter with respect to the life-elongation rate; measuring a elongation rate between before and after the use of the bolt to be assessed; and assessing the remaining lifespan of the bolt with the use of the elongation rate between before and after the use of the bolt to be assessed and the lifespan-assessment diagram.
    • 本发明旨在提供一种用于评估具有比常规方法更高精度的螺栓的剩余寿命的方法,其可以应用于包括由蠕变损伤引起的较少组织变化的高合金的螺栓。 本发明提供一种用于评估在高温下使用的螺栓的剩余寿命的方法,包括:对构成要评估的螺栓的螺栓材料进行蠕变试验,并确定寿命和寿命延长率; 根据寿命和蠕变试验温度确定时间 - 温度参数; 通过绘制时间 - 温度参数相对于寿命延长率来创建寿命评估图; 测量在使用要评估的螺栓之前和之后的伸长率; 并使用在评估螺栓的使用前后的伸长率和寿命评估图来评估螺栓的剩余寿命。
