However , the research and application are limited within two - dimensional field 然而對面積測量的研究應用均局限于平面。
In this thesis , not only the two - dimensional field problem , but also the simple three - dimensional model are explored and calculated , and the results are satisfactory by comparing with the real ones 本文以二維場為主要研究對象,同時對三維模型進行了探索,得到了比較理想的結(jié)果。
Numerical solution is mainly applied for this problem . adopting certain assumptions , this paper presents an approximate method of obtaining the temperature field by green ' s function , and gives the solution of a two - dimensional field involving a circular vacant flaw 通常采用數(shù)值計算,本文通過采用一定的假設(shè)條件,提出了溫度場解析求解的近似方法,并對含有二維圓形空腔缺陷的試件溫度場進行了求解。
