The feeding head shape of a die and a streamlined sprue runner were designed after an analysis on the cross sectional shape and the extrusion forming ability of PA66 material. 通过对异型材截面形状及原材料挤出成型性能分析,设计了正确的口模形状及合理的流线形流道;
TESTING A Research on Spherical Insulating Feeding Head 半保温球形冒口的试验研究
Under the constant condition of forage type, feeding method and the daily amount of feed, we investigated ru-minal pH and the number of ruminal ciliate in 31 head of cattle before and after feeding. 在饲料种类、饲喂方法、日粮总量等不变情况下,对31头黄牛食前食后的瘤胃液PH值及纤毛虫数作了调查。
Conclusions: The modified gastric feeding is helpful to the early nutrition and beneficial to improve gut function and the nutritional condition of the severe head injured patients. 结论:改良后的鼻饲方法和喂养计划,有助于脑损伤后早期肠道营养有效和安全地实施,对改善病人营养状况,有极其重要的临床意义。
The rationalities for early nasogastric feeding after severe head injury 严重脑损伤后早期肠内营养支持的合理应用
The system bears altogether 18 carding heads, and the control of fur-fiber feeding and control of step motor for every carding head is implemented by one single chip. Flowers ( 3) D shape. 系统共有18个梳理头,每个梳理头的喂毛控制和步进电机控制分别由一个单片机完成。编辑的花型数据通过U盘方便地传送给控制系统;
Design of 3D Feeding Head for Laser Rapid Manufacturing 用于激光快速制造的三维送粉头的设计
Using cutting depth, distance of picks, feeding speed and rotation speed of mining head as design variants, aiming at minimum cutting energy consumption, a process parameters optimizing model of mining head was established. 以采集头的行走速度、滚筒切割速度、切削深度及截齿的截线距为设计变量,以采集头最小切削能耗为目标,建立了采集头工作参数优化设计模型。
Analysis Study on Feeding System of All-hydraulic Power Head Type Drill Rig 全液压动力头式钻机给进系统的分析研究
Meanwhile introduced the development of the auxiliary equipment of extruder from the temperature control device 、 feeding device and head side pressing device, and explained the development trend of extrusion equipment from 3 aspects of application extending 、 train and new product. 同时从温控装置、喂料装置和机头测压装置介绍了挤出机辅属装置的发展情况,并从用途扩展、联动线以及新产品开发3个方面阐述了挤出设备的发展方向。
Methods The selective common iliac arteriography was performed in 182 patients ( 216 hips). According to the images, the feeding arteries of the femoral head were determined. 方法收集182例(216髋)患者,行选择性髂总动脉造影,根据影像确定股骨头供血动脉,行超选择性插管并经导管进行局部药物治疗,记录相关资料。
When the feeding artery injuried in trauma or treatment of a sudden block will result in ischemia, which will inevitably lead to a series of changes of the femoral head tissue, eventually leading to bone necrosis. 所以股骨头的血供比较贫乏,当供血动脉在外伤或治疗时被损伤而突然阻断将造成缺血时,必然会引起股骨头组织细胞的一系列变化,最终导致骨坏死。
The automatic feeding device and the finishing head are tested respectively. 最后通过实验,对自动进给装置和柔性光整头分别进行了测试。
The designing and the control program of the key part of the machine tool are analyzed. The theory designing program of the feeding for cutter head is finished, and the automatic feeding is complemented by using the Archimedean thread. 本文通过对机床关键部分的机械方案和控制方案的分析,完成了刀盘进给部分的理论设计方案,通过使用阿基米德螺线平面螺纹实现了自动进刀。
