We also got STM images of denatured fibroin under stress or by methanolin molecular level. We found the conformation of silk fibroin is changed from α-helixand random coil structures to β-strand and loosed α-helix formation. We employed the STM to explore the structure and morphology of silk fibroinin the middle silk gland of mature silkworm.

我们在分子水平上对在冰冻和甲醇处理下的丝心蛋白的变性情况进行了STM研究，我们发现丝心蛋白的构象由α-螺旋结构和无规线团的结构向β-伸展链和松散折叠α-螺旋结构转变我们还用STM对熟蚕的中部丝腺体中的丝心蛋白的结构形态进行了研究。

In this system the motion controlling centers upon regulating the speed of wire feeding and movement of lead screw in each direction.Four motors separately drive the wire-feeding tape roll and the lead screw move respectively following their directions of X, Y, Z axis. If all the motors are controlled by 89C51 directly,it will rise great difficulty for software and hardware implementation. So the suggested solution is to combine the microcomputer with stepper motor driver and control of their motion.

在本系统中运动控制的关键即送丝与各丝杠移动的调节，由四个电机分别驱动X，Y，Z轴方向的丝杠行走以及送丝操作，运动控制部分如果用89C51直接驱动各电机则在软件和硬件实现上都比较困难的，所以选用单片机与步进电机驱动器结合起来控制它们的运动。
