And have driven compared to shaftless tension control more flexible, but variable conditions also tension control more difficult, and that's asked us to practice in the trial and the law, achieve the best fit mode.

与有轴传动相比，无轴传动的张力控制更加灵活，但可变因素的增加也提高了张力控制的难度，这就要求我们在实践中不断摸索三者的规律，达到最佳的配合模式。

Our results indicated that (1)SO_2 derivatives could dose-dependently relax the isolated aorta rings with or without endothelium precontracted by NE, no difference was found for the rings with and without endothelium;(2)Levels of cAMP and 6-Keto(PGI_2) in isolated aortic rings were increased by SO_2 derivatives in a dose-dependent way, which were independent of endothelium;(3)SO_2 derivatives decreased cGMP levels in the rings, but not significantly; The decrease of cGMP levels was also independent of endothelium;(4)No changes of TXB_2 in rings with or without endothelium were observed;(5)Whether presence or absence of endothelium, cAMP/cGMP and 6-Keto/TXB_2 ratios were increased significantly.

结果：①SO_2衍生物对去甲肾上腺素预收缩的内皮完整和去除内皮的大鼠胸主动脉血管环均呈浓度依赖性舒张作用，且其张力变化在内皮完整与去内皮的血管环之间无显著性差异；②SO_2衍生物可引起血管组织中cAMP、6-Keto(即PGI_2)含量剂量依赖性增加，其增加程度与内皮无关；③SO_2衍生物对血管环cGMP含量呈降低趋势但在统计学上无显著意义，且对去除内皮血管无显著影响；④SO_2衍生物对去内皮或内皮完整血管环的TXB_2含量均无明显影响；⑤无论是否去除内皮，SO_2衍生物均可引起cAMP／cGMP和6-Keto／TXB_2比值显著升高。

During the research and fabrication, many problems encountered, especially principle tests, design of mechatronics system, synchronal control between press (cross-section correction) feeding and preforming/bending feeding and damped oscillation have been solved.

Control of a non-stretch is mainly driven by paper Division tension, the feed roller speed ratio, rich text (press how to work out before drawing roller) ratio of a few implications.

无轴传动张力控制主要受供纸部张力、送纸辊速比、RTF（折报机三角板前的拉纸辊）速比等几方面的影响。

If you bent or folded rock, the inside of the curve was in a state of compression, the outside of the curve was under great tension, and somewhere in the middle was the surface of no strain.

&假如你把一块岩石弯曲，曲面的内侧会是一种紧缩的状态，外侧则处于巨大的张力，而在中间的某处则是光滑无痕的平面。&

In this paper, the web tension variation regularity is studied based on the printing test-bed with shiftless driver in printing. This paper offers the basis for establishing the tension control of web press. It is very significant for improving the speed and quality of web press and reducing the difference between domestic press and oversea advanced press.
