Wraps the bottom is a ring, the jacketed wall to the upward contraction tube, the tube cavity cross section diameter is equal to or be smaller than inward wraps the thermos pot bottom diameter, the jacketed wall upward pinch-out, interacts the part in a set of bottom and the jacketed wall, digs out some inclined half circular slot, wraps on the bottom to open 2-4 reservation spiral nail hole.

套底为一个圆环，套壁为向内向上收缩的筒，筒腔断面直径等于或小于所套热水壶壶底直径，套壁向上尖灭，在套底与套壁交结的部分，挖出一些倾斜的半圆槽，套底上开2—4个预留螺钉孔。

The stress distribution of the semi-circular breakwaters with holes by different quantitative ice value to water level, especially the stress distribution of holes is analyzed. The effect of the stress distribution to the holes and the wall thickness are discussed. At last, the result is compared to the stress distribution by wave

应用ANSYS程序计算了不同水位不同量级冰力作用下开孔半圆型防波堤的应力分布，尤其分析了孔洞周围的应力分布；并且讨论了开孔和壁厚对于应力分布的影响；最后将分析结果与波浪力作用下的应力分布进行了比较。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
