Yambajan is famous for its wide range of hot springs, from ones with the highest temperatures in the country to boiling geysers. 羊八井,以拥有包括全中国温度最高的温泉以及间歇泉在内的大量温泉而著名。
The correlations apply to bitumen-derived middle distillates that have a wide range of boiling points. 这些关联式可用来预测油砂沥青改质得到的宽馏程中间馏分的十六烷值和烟点。
The experimental results indicate that both PAM and ODA enhance the flow boiling heat transfer of water, and have an optimum range of concentration PAM can reduce the drag of flow boiling to enhance boiling heat transfer by increasing flow velocity. 研究结果表明,W/O型聚丙烯酰胺和十八烷胺都具有强化流动沸腾传热的性能,而且有最佳浓度范围。PAM还具有减阻性能,因而可提高流速来强化流动沸腾传热。
By using the semi-theoretical and semi-empirical formula obtained as a result of the present study it is possible in a extensive range of tests accurately predict the critical heat-flux density of the jet-flow boiling. 本研究得到的半理论半经验公式在广泛的实验范围内能很好的预示喷流沸腾的临界热流密度。
The experimental results show that within a certain range of heat flux the flow boiling heat transfer coefficient in an annulus is larger than an empty tube by 80%; the overall heat transfer coefficient is increased on an average by 60%. 实验结果表明,在一定的热通量范围,环隙内流动沸腾传热系数较空管的平均提高80%,总传热系数平均提高60%。
In the wide range of inlet subcooling ( 0 K system flow condition, namely, ( 1) stable two-phase flow, ( 2) bulk and subcooled boiling unstable flow, ( 3) subcooled boiling and single phase stable flow. 在进口过冷度相当宽范围内(OK<ΔT<28K),对系统流条件,存在3个区域,即稳定的两相流,整体和过冷沸腾不稳定流和过冷沸腾以及单相稳定流。
