Methods: After transferred pcDNA3.1/hTM plasmid into rabbit artery by high-pressure injection, rabbit common iliac artery were cut and anastomosed again. At the 14 days and 28days after second operation, we checked inside diameter of anastomotic stoma and blood flow velocity by color Doppler. The treated artery were sliced and stained by Verhoeff. Local neointima formation and the ratio stenosis of intervascular were calculated by computer.

In this paper, the effects of the rigid body motions and low frequency surface errors on the image quality were analyzed. Quadratic equations were used to build the mathematical model of the Wolter type I and II X-ray telescopes and reduce the computational complexity of ray tracing. With the help of a self-developed optical surface analysis code, the effects of the perturbations of the mirrors on the image quality was analyzed and the growth of the image spot formed by deformed telescopes was calculated, this is important for giving the reasonable fabrication tolerance.
