如果您是首席辅导员并且退出了某个项目，则另外一名辅导员将成为首席辅导员。
In order to improve actual performance of the material in application, a pharmaceutical extruder-rounder is used to turn the powder material into spherical grains of a certain grain size in order to facilitate its application in the treatment of industrial and domestic ammonia nitrogen wastewater.
为了提高材料的实际应用性能，本研究将医药用挤出-滚圆机引入实验，将粉体材料制备成一定粒径的球形多孔颗粒，以方便应用于工业和生活氨氮废水的处理。
Besides, when changing the speed, it is necessary to properly adjust the size of the screw configuration and dies to improve the screw transmission capacity of materials in case of plugging or steam back-flow in the extruder.
另外，在改变转速的同时，要适当调整螺杆配置以及模孔大小，改变螺旋对物料的输送能力以防止堵机、反喷现象的发生。

Special design vacuum sizing tank can ensure the stability of size and roundness, Speed controllers are used in extruder, haul-off to offer stability and precision.
特殊设计的真空定径箱，可以确保稳定的直径尺寸和圆整度，使用速度控制系统，使牵引速度稳定。
The integrated wallboard extrusion for aluminum profiles feature high width - height ratio of section (about 50 - 100), complex shape, high precision and large size. Therefore, the wallboard has to be extruded with a flat extruding tube in a large extruder.
铝型材整体壁板断面宽高比大（50～100以上）、形状复杂、精度高、壁薄以及外形轮廓与长度尺寸大等特点决定了其在大型挤压机上采用扁挤压筒进行挤压的生产方式。
The design key of complex extruder dies for extruding profile rubber sealing stips was how to define the profile and size of the extruder die, how to make the pressure and velocity of the extruding rubber uniform at the exit of die.
组合式异型橡胶密封条挤出模头设计的要点是如何确定口模的形状尺寸并使各胶料质点的出口压力及流速均匀一致。
