急性气肿性胆囊炎的老年患者，经常只以右上腹胀痛表现而缺乏典型的症候，术前诊断不容易，当超音波检查发现胆囊无法清楚显现而怀疑胆囊内有气体存在时，必须安排腹部X光及电脑断层作更进一步确认，一旦确立诊断，必须作紧急手术治疗以降低死亡的危险性。

In this paper, several traditional models for computing are introduced at first. Conferring probability theory, the load boundary condition of that collector is analyzed, the characteristic values of Tubesheet in different design reference periods are computed. Based on homogenization method, after lots of numerical experiments, the mechanical characteristic of Tubesheet controlled different structure parameters is studied, and an empiristic formulas that could simplify Tubesheet to stiffen plate is gained. Then, G-M method is employed and Tubesheet is simplified to a normal plate.
