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。

In recent years, through conducting market research and investigations, having interviews with customers to get acquainted to the market demands, by conducting all-round technical renovation, adopting new technology and new process to existing products, the company has developed and manufactured Series JC Electric Multi-purpose Operation Table and Series JCY Hydraulic Operation Table for Type C arm equipment, Type-JQ Multi-purpose Intermission Traction Bed, JC-CQ Bone Traction Frame and Backbone Operation Bracket, further satisfying the demands of the customers.

近年来公司通过市场调研、走访客户及市场发展的需求，我们对原有产品进行了全面技术更新，充分应用新技术、新工艺开发生产了为C型臂配套的综合电动手术台JC系列和电动液压手术台JCY系列；JC-JQ多功能间歇牵引床系列； JC-GQ骨科牵引架系列以及脊柱架。更进一步满足了用户的需求。

Methods］When scoliosis of patients were corrected to a certain degree after three weeks of halo pelvic distraction, the most serious collapsed ribs of concave side of the curve underwent a transverse incision the cross ribs.

［目的］介绍35例重度脊柱侧弯合并严重胸廓塌陷的病例，在颅盆牵引的过程中，同时采用肋骨成形术加水平牵引治疗胸廓塌陷。

Methods］When scoliosis of patients were corrected to a certain degree after three weeks of halo pelvic distraction, the most serious collapsed ribs of concave side of the curve underwent a transverse incision the cross ribs. A special rib bender was used to bend the exposed 3 to 6 ribs. The bent ribs were pulled up by double-stranded 10# thick silk which was extended out through the skin and fixed in the upright post of the instrument of Halo pelvic distraction with rubber membranes.

方法］颅盆牵引3周后，脊柱侧弯矫正到一定程度时，在侧弯凹侧肋骨塌陷最重的部位，与肋骨交叉作横切口，暴露3～6条肋骨，用特制的肋骨折弯器将肋骨折弯变圆，用10号双股粗丝线将每条肋骨提起，自皮肤穿出通过橡皮膜在颅盆装置的立柱上作牵引。

Traction is measured by coefficient of traction, which is the ratio of transmitted force to contact force.

牵引系数是衡量牵引的，是传输力比接触力。

The test of traction resistance for Medium Depth Planter reveals almost a line relation between its tow resistance and depth of soil loose.

深松插干植树机进行的牵引阻力测试揭示了深松插干植树机的松土深度与牵引阻力几乎为一线性关系。

Methods 15 Mongrel dogs were subjected to be lengthened of the unilateral or bilateral mandibles using the home made type MS 1 mandibular distracter,and the regular X ray examinations were made.

采用自行研制的MS 1型内置式下颌骨骨牵引延长器，对 15只犬分别进行下颌骨单侧及双侧骨牵引延长实验，X线定期检查。

Methods Unilateral mandibular osteotomies were performed in 30 mature rabbits, the mandibles of 30 rabbits were lengthened by 4mm using a distracter.

方法在30只成年大耳白兔的一侧下颌骨前部行骨切开术，用牵引器延长一侧下颌骨4mm，分别于牵张完成后的第1，3，7，14，28天处死一组动物，取牵引区新生骨痂行组织学及OPG免疫组化染色。

The mechanical properties of these silk fibers were also measured. To explore the control capability of spider on the spinning process and its influence on the mechanical properties of dragline silk, spiders were anaesthetized and the mechanical properties of dragline silk reeled from an being anaesthetized spider were measured.
