弹丸生成的物理模型和生成时间估算

THE PHYSICAL MODEL AND TIME ESTIMATION FOR PELLET GROWING

弹丸注入是聚变工程和实验中研究等离子体加料、控制等离子体密度和杂质的重要手段。介绍了弹丸在低温恒温器冷凝腔中生成的物理模型，并由此估算了弹丸的生成时间，对弹丸实际制造。

Pellet injection is an important way for plasma fuelling、plasma density and impurity control in fusion engineering and experimental research. This article describes the physical model of pellet growing in the condensation cavity of cryostat, and makes attempts to estimate the growing time of pellet, which has played a very important role in the pellet manufacturing and experimental adjustment of pellet injector.
