在制卡和会员卡制作过程中由张力控制器来控制制卡和会员卡制作张力的恒定，是套印准确的关键所以，张力控制系统是任何卷筒制卡和会员卡制作机的一个重要机构，它在很大程度上决定印品的套印准度，张力控制机构主要设于放料部分，制卡和会员卡制作工位和放收料牵引及收卷机构、料卷输出需要阻力，料卷转动有惯性，卷料自身也存在一定的张力值，加上制卡和会员卡制作速度的拉力牵引，制卡和会员卡制作过程中各色组套印对被印材料的阻力使得放卷、制卡和会员卡制作、收卷机构的张力控制显得尤为重要，张力控制的大小应视材料的厚薄、质料宽窄来决定。

The method of Agrobacterium-mediated transformation is the most widely used in genetic transformation. To this day, only several genotypes such as Bobwhite and Yangmai158 have been used in transformation successfully. To widen the recipient genotypes, ten different genotypes were transformated by Agrobacterium-mediated In our study, transformation efficiency of B31706 and B31575 were significantly higher than Bobwhite. Moreover, regeneration rate and resistant plantlet rate of Agrobacterium-mediated genetic transformation in B31706 immature embryos callus was the highest one among the genotypes.

农杆菌介导法是目前应用较为广泛的转化方法之一，但在小麦中，只有包括Bobwhite和扬麦158在内的少数几个基因型被成功用于农杆菌介导的小麦遗传转化中，为了拓宽小麦农杆菌转化的受体基因型范围，本研究对10个不同基因型的材料进行了转化实验。B31706和B31575的转化率明显高于对照材料Bobwhite 。
