The investigation of the solution treatment of hot-rolled TWIP steel of three different compositions (Fe-25Mn-4Si-2Al, Fe-30Mn-4Si-2Al and Fe-30Mn-3Si3Al) revealed that prolonging the temperature holding time can increase the elongation with no obvious change found in strength.

对3种不同成分的TWIP钢(Fe-25Mn-4Si-2Al， Fe-30Mn-4Si-2Al， Fe-30Mn-3Si-3Al)进行热轧后的热处理实验，结果表明，增加固溶处理的保温时间，可提高TWIP钢的延伸率，而强度的变化并不明显。

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。
