Excel in line of force can maintain goods seam place is firm and close together, can bear the hot action of 200 ℃, be able to bear or endure saline be soiled is eroded, do not shrink bouncy, in damp environment, yarn diameter increases 24 ～ 28 ％, those who assured the pinhole inside the shoe is close-grained, of puissant yarn wet expansile more appropriate than filament at tailor shoe kind goods.

高强力线可保持制品缝接处牢固紧密，可承受200℃的热作用，耐盐渍侵蚀、不缩有弹性，在潮湿环境中，纱线直径增大24～28％，保证了鞋内针孔的密实，强力纱线的湿膨胀性比长丝更适宜于缝制鞋类制品。

New multi—objectives function (including mill stand longitudinal stiffness, distribution coefficient of loaded pressure between rolls, weight of mill stand, rolling power, rolls loaded gap profile changeability of bending force, transverse mill stand stiffness of bending force, transverse mill stand stiffness of rolling load) multi—constraints (including rolls strength, spindle strength, backup roll bearing load, minimum rollable gauge, roll surface temperature rise) rolls system parameters optimization model of four—high cold strip mill is established, and programme for mill structural illustration creation on the platform of AutoCad designs is compiled. With this as basis, rolls system parameters of Yichang thin strip corporation's 1219 cold mill are calculated using SUMT (subsequent unconstrained minimization technology).

本文建立了以板形和板凸度控制特性为目标的四辊轧机多目标函数（包括轧机纵向刚度、辊间压力分布系数、轧机重量、功率、弯辊力对轧机辊缝形状改变能力、对弯辊力的横向刚度、对轧制力的横向刚度）、多约束条件（包括轧辊强度、接轴强度、支承辊轴承负荷、最小可轧厚度、轧辊温升等）的辊系参数优化模型，以此模型为基础，利用惩罚函数法计算了益昌薄板公司1219冷轧机辊系参数，编制了AutoCAD平台下的轧机结构示意图自动图形软件。

Assembling a quilt requires some thinking ahead. First, a quilter selects a pattern and then cuts pieces of fabric and sews them together to form an overall design. Usually, smaller pieces of material are sewn together into larger blocks or squares, and then those blocks are stitched together to make the top layer of the quilt. Once the top layer is as big as the quilter wants, it's joined together with the padding and the bottom layer using a frame.

缝制拼布需要事前规划；首先，缝纫者会挑选希望的图案花色，然后将织物剪成一片片，再将它们缝在一起，形成一个完整的设计样式；通常，较为小片的布料会被缝制成一大块或正方型，接著，再将这些方块缝成一大片，当做成品的表布；一旦表布的尺寸达到缝纫者想要的大小后，就可以使用框架将表布、填料及底布结合成一体。

Methods Fifteen rabbits were divided into three groups: group A (posterior limbs was completely cut off and posterior tibia artery was ligated with posterior tibia vein), group B (posterior limb was uncompletely cut off and posterior tibia artery was ligated with posterior tibia vein), group C posterior limb was completely cut off and traditional operation type was applied to ligate the posterior tibia artery with posterior tibia artery (control group.

用15只兔分3组：A组为完全离断小腿胫后动脉缝接胫后静脉组，B组为部分离断小腿胫后动脉缝接胫后静脉组，C组为完全离断小腿应用传统的胫后动脉缝接胫后动脉对照组，3组均结扎胫前动脉，保留胫前静脉等未动脉化的静脉及缝接其它离断软组织。

The influence of process parameters, such as the single pulse energy, overlapping and optical configurations on the laser cutting quality （ cutting width, the smoothness of cutting rim, lancing taper, and cutting efficiency） were investigated in detail.

研究了激光切割工艺参数-如单脉冲能量、搭接量、光学扩束系统参数等，对切割质量（如切缝大小、切缝边沿整齐度、切割锥度、效率等）的影响。

An automatic arc welding machine for saddle joint seam on large diameter cylinders was designed and its structure,components,characteristic and working principle were discribed in this paper.
