本文首先对甲基丙烯酸丁酯和甲基丙烯酸甲酯的聚合特性进行了对比研究，用膨胀计法测定了两者在不同引发条件下的聚合动力学，证实了甲基丙烯酸丁酯的聚合活性比甲酯要低，聚合条件更为严格。

The only alternative and referential way to predict the phase transformation temperature is to make use of the continuous cooling transformation diagrams, which are measured dilatometer curves that have not taken the effect of practical welding conditions into account.

由于焊接过程的瞬时性和焊接热影响区温度场、应力场的复杂性，该区域的组织转变往往并不完全遵守热处理条件下CCT 图所反映出的相变规律，因此为了提高焊接接头的性能，有必要深入研究真实焊接条件下热影响区组织的相变规律，尤其是马氏体组织的相变规律，因为在含碳量较高或合金元素较多的情况下，这两类钢的淬透性较强，在焊接热影响区极易形成高硬度马氏体组织，从而严重影响焊接接头的性能。

The best optimum conditions of the Agrobacterium mediated genetic transfornation were that leaves explants were immersed in the diluter 10 times Agrobacterium bacilli at OD600 of 0.6 for 8 minutes after being pre-cultured for 2 days,and then co-cultivated for 3 days.Then these explants were transferred to selected and rooting medium which contained 50 mg/L Kanamycin and 500 mg/L Carbenicillin.According to the transformation system, 54 transgenic plants were initially screened,then after PCR analysis and RT-PCR analysis 25 transgenic plants were obtained.
