surface traverse

Surface hardness of bearing steet decreased after quenching, because temperature traverse quickly in cooling-off The case happens easily when the time of steam film is longer and the temperature of quenching oil is lower.

轴承钢油淬后往往发生表面硬度偏低，其原因是因为冷却途中冷速急剧变化引起的，特别是在蒸汽膜期长，特征温度低的油中淬火时更易发生。

The reflectivity-temperature curve of the probe surface to 6328 A laser, and the temperature traverse curve of the staff installed perpendicularly on a high temperature wall-plate are given.

并且通过实验，给出了探头表面对6328A橙红激光的反射率随温度变化的曲线，以及高温壁板上垂直装置的杆件上的温度分布曲线。

Analysis of Unstable Temperature Traverse of Thin Plates Subjected to Invariant in Time Heat Source on Its Surface This paper investigates unstable temperature traverse of thin plates, whose boundary is under convective heat transfer to air.

在表面有恒定热源作用薄板的不稳定温度场分析本文研究了薄板（δ≤0.6厘米）在一侧表面受不变热量q，边界处于空气对流传热条件下不稳定温度场的分布问题。
