According to JJG (railway)140-2002 "Rule on Calibrating Rail Track Thermometer",and regarding with the new type of HWG-1 high-precision calibrating device for rail track thermometer,the author introduc.
钢轨测温计(以下简称轨温计)是一种测量钢轨表面温度的测量仪器,检定时使用轨温计检定仪,检定仪工作台表面温度均匀性,与检定结果直接相关。
2) rail thermometre
路轨测温计
3) design stress-free temperature of rail
设计锁定轨温
1.
Research conclusions:When designing continuous welded rail on bridge in the small radius curve section,these factors should be especially considered: increasing lateral ballast resistance,reducing additional forces of the continuous welded rail on bridge,and properly increasing the design stress-free temperature of rail.
研究结论:小半径曲线地段桥上无缝线路设计应重点从提高线路横向阻力、降低桥上无缝线路钢轨附加力、适当提高设计锁定轨温等几方面考虑。
4) temperature trajectory
温度轨迹
5) stress-free temperature
锁定轨温
1.
In order to better guide the design,laying and maintenance of welded turnouts,the effects of stress-free temperature difference between two railway lines on the rail displacement and temperature force of a welded turnout were investigated.
为了更好地指导无缝道岔的设计、施工和维护,探讨了不同线路间存在铺设锁定轨温差时,铺设锁定轨温差对无缝道岔受力和变形的影响以及与道岔联结型式、道岔号码、辙叉型式和道床纵向阻力的关系。

Thus, in order to guarantee the service life and safety of rail track, it is necessary to heat the rigid CWR track during track-laying to control stress-free temperature of rail.
锁定轨温即在钢轨内部没有应力时,对钢轨进行锁定时的轨温,也叫零应力轨温。
6) Rail temperature
钢轨温度
补充资料：深温计
| 深温计 bathy thermograph 连续测量并记录水温随深度变化的仪器。全称为深度温度计。有机械式、电子式和投弃式3种：①机械式深温计。用充满液体的细金属管为感温元件，用波纹管为感压元件。随着仪器投放深度的变化，自动绘出水温随深度变化的曲线。工作深度达300米左右，温度精确度约±0.05℃，深度精确度约±1％。在船只定点或走航时用钢索吊放使用。②电子式深温计。用温度传感器和压力传感器把海水的温度和探头的投放深度转换为电信号，进行测量和记录的装置。有的电子式深温计用声波传送测量信号。③投弃式深温计。属电子式深温计，但水下探头只一次使用而废弃。有船用、潜器用和飞机用3种仪器。可以在航行中成批使用， 不受恶劣天气和海况的限制，操作方便。 |
