Firstly, velocity expression of translational parallel manipulator was presented based on the screw theory. Secondly, the actuated screw, the actively unactuated screws and idle screws of each limb were determined according to the reciprocal screw theory. Then, all basic kinematic chains were enumerated by means of the number of limb connectivity and the limbs containing closed-loops were obtained by replacing the passive prismatic joints in the basic kinematic chains with planar closed-loop structures.

首先基于螺旋理论给出移动并联机构的速度表达式，然后根据互易螺旋理论确定出分支的主动螺旋、可动非主动螺旋和惰性螺旋，再依照分支连接度的不同列举出所有可行的基本分支运动链，并通过运动副替换得到分支中含有闭回路结构的运动链，最后利用所综合出的支链按照主动副的配置要求将动平台和静平台连接起来即可实现预期的机构。

A mixing performance analysis on the different screw configuration in the process of twin screw codirectional extrusion;2. The filling ratios in the main reactive zones were estimated by clam barrel for different screw configuration s.

研究了不同螺杆构型下的充满度以及低密度聚乙烯熔融接枝马来酸酐的过程，探讨了不同螺杆构型下充满度与接枝反应挤出过程的关系。

The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement. Among 160 thoracic pedicle screws that were implanted in 34 cases, 148 screws (92.5%) were accurately inserted inside the costotransverse unit, and 12 screws (7.5%) were misplaced according to the image of X-ray and CT thin-slice scan.

应用椎弓根外内固定技术2004/2007年在中山大学附属第三医院骨科治疗34例患者，固定前采用CT加密扫描测量进钉点、进钉点至椎体前缘的深度、进钉角度和直径，固定中椎弓根钉入点为横突尖，进钉方向为平均向头侧倾斜10°~ 20°、与中线成角30°~40°，顺椎弓根外侧皮质进入椎体，固定后CT加密扫描观察螺钉周围的皮质骨是否完整、是否靠近节段血管、是否穿透皮质骨，评价置入钉的准确性和安全性。34例患者共置入160枚胸椎椎弓根螺钉，固定后CT加密扫描和X射线片观察到148枚(92.5%)螺钉置入准确，12枚(7.5%)螺钉发生错置。

Finally heat the starch to 80℃dextrinize 2h,keep warm 0.5h,then cooled to 40℃,add 2.8%CAN initiator,7.5%MMA monomer,sealed and stir 3.3hours of the nitrogen atmosphere,using the screw rod center distance is 32mm,expects the tube diameter phi300mm major axis compared to L/D is 12.5 double screw rods extruding machines,controls the screw rod rotational speed 100rpm sample water content when 20%squeezes out,and the results indictated that the sample may bear 302℃within the high temperature,the water resistance is 14.7%,buried in the simple earth passes through about 180 day to be allowed to achieve the nearly 60%weightlessness rate, and can be basically completely degrades.

因此将淀粉80℃糊化2h，保温0.5h，40℃添加2.8%引发剂，7.5%MMA单体，通氮气密封搅拌反应3.3小时后的接枝产物，利用螺杆中心距为32mm，料筒直径f300mm长径比L/D为12.5的双螺杆挤出机，控制螺杆转速100rpm样品含水量20%时挤出，测定知道样品可以耐302℃以内的高温，耐水性为14.7%，在简单土埋的情况下，经过180天左右可以达到近60%的失重率，可以说基本上完全降解。
