The better result was obtained by the high temperature surface treatment of carbon fiber under the atmosphere of nitrogen.
实验的结果表明:在氮气保护下,碳纤维的高温表面处理效果较好。
Traditional geothermal plants exploit natural systems in which water seeps down into porous rocks in the ground and emerges back at the surface at a high temperature.
传统的地热发电厂利用了这样一种自然系统,即水分下降至地壳的渗透岩层中,而后又受热蒸腾到地表。
This is not true in oil quenching, when the surface temperature may be high during the critical stages of quenching.
但油淬情况就不是如此,因为油淬时在淬火临界阶段零件表面的温度可能仍然很高。
