Temperature field and failure analysis of die-casting die
Casting Aluminium alloys Die-casting die Temperature field
2009/12/1
Purpose: Dies for aluminium alloys die-casting fail because of a great number of a different and simultaneously
operating factors. Some of them may be controlled to some extent by the die-casting exp...

柴油机功率强化前后气缸盖的温度场模拟与试验（Simulation and Experiment of Temperature Field on Diesel Engine Cylinder Head before and after Enhancement of Power）
柴油机 气缸盖 温度场
2009/5/22
对功率强化前后的柴油机分别进行了性能仿真计算，进而确定了缸盖温度场计算的边界条件；利用有限元软件对气缸盖进行三维稳态热分析，并考虑了冷却水沸腾换热的影响；在该柴油机的单缸试验机上进行了稳态温度场测量试验，分析了试验和计算结果；得到了火力面边界条件的设置规律、稳态温度场随工况的变化关系和单缸机与多缸机的稳态温度场差别。
Formation of cobalt hydrides in low temperature field evaporation
cobalt hydrides field evaporation ab initio calculations
2005/3/27
In the field evaporation process of cobalt in an atmosphere of hydrogen 10–6 Pa at a temperature of 20 K, both the ions of cobalt and the ones of CoHx (where x = 1, 2 and 3) have been observed. Since ...
