To be able to predict the throughput of a single-screw extruder or the metering time of
an injection moulding machine for a given screw geometry, set of processing conditions
and polymeric material is important both for practical and designing purposes. The model
is based on viewing the entire screw simply as a pump, conveying a solid and a molten
fraction. The evolution of the solid fraction is the essence of the plastication process, but
under a particular hypothesis on solid bed acceleration, its influence on the throughput is
nil. This allows getting a good estimate on the throughput and pressure development along
the screw. Calculations are compared to a large set of experiments available from the literature.
Consistent agreement with these published results is obtained, both for throughput
and pressure along the screw. The effect of the plasticating process on the throughput is
non-existent if the plastication

注塑机一个挤出机单螺杆为了能够预测吞吐量的或计量的时候，为某一特定螺杆几何，设置加工条件
和高分子材料都是很重要的实用和设计用途。示范
是根据收视整个螺杆仅仅当作一种泵，输送了坚实和熔融分数。演变的固相分数是最重要的过程中，但根据某一设计车床加速度，它的影响，吞吐量
为零。这使得获得一个良好的估计，对吞吐量和压力，在螺钉上作出改进。如意算盘相比，有一大套实验，可从文学作品。一致同意发表这些成果是得到了，无论是吞吐量和压力沿螺钉。影响的塑化进程，对吞吐量不存在，如果粉料长度是短的，而且更明显的，如果粉料长度需要一个良好的一部分，螺杆长度（举例来说，在较高的螺杆旋转率） 。这降低了吞吐量的价值和扩大了压力峰值。该模型也表明，螺杆几何是最重要的参数，其次是高分子流变学和加工条件。熔化性能和长度似乎干预，以程度较轻。最后，该模型是用螺钉设计，突出的影响，压缩区吞吐量。

看不懂,都是生词,太专业了!
