In order to explore the change of pseudo-density to the effect of material rigidity and set up the relation between them for density variable method, we presented FEM to deal with the problem.
为了探讨变密度法中伪密度的变化对材料刚度的影响，并建立两者之间的力学关系，本文采用有限元法研究这一问题。
We have succeeded in making a kind of phase change material (PCM) of high thermal storage density, good corrosion-resistant performance and low cost of preparation by powder sintering method.
本研究采用粉末烧结工艺将陶土分别同性能优良的高温熔融盐复合，成功地制备出蓄热密度高、耐腐蚀性好且成本低廉的相变蓄热复合材料。
