It has been found that there are some texture flaws such as large grain、badly distorted twin and streaky structure. But recrystallization grains ofaround 19μm in diameter on average are obtainable through heat treatment at300℃for 30min by air-cooling, meanwhile the twin and streaky structurethat would weaken the plasticity of alloy are eliminated; significant elementsare holding temperature、holding time、cool-down methods. Mechanicalproperties of tube are obtained, simple tension elongation ratio of arc testsample increases from 10.8% to 20.1%, elongation ratio with elastic internaldie of tube increases from 8.0% to 14.9%.

On the ground of simple compression test, a damage equation which reflect structural strength change with pressure is carried out. And it discriminated from the strain types of common soft soil and structural soft soil.

通过分析计算，明确了先期固结压力和结构强度的概念；提出了结构稳定系数，较为准确地判断出土的结构强度的影响程度，为工程设计提供参考；④基于单向压缩试验，提出了结构强度随压力变化的损伤方程；区分了一般性软土与有结构强度的土的压密类型。

Here, using the mathematica software and the outcome of the computation , we can see which interval is better easily. In chapter 2, the author firstly studies three two-stage simultaneous confidence intervals for the pairwise treatments with the same precision and reliability in a balance one-way classification model ,then work out the optimal sample size of the first stage by numerial computation.
