airflow

This airflow pushes waste toward the bottom of the toilet, drawing it into a bag, holding solid waste, but letting the air through.

这样一来，排泄物会被气流抽到马桶底部的一个袋中，固体部分被收集起来，空气则被过滤掉。

Although the new model better illustrates how spiders "fly," there is still room for refinement, and the team plans to observe spiders in turbulent airflow inside wind tunnels to improve the model.

尽管新模式能更好地解释蜘蛛为何能“飞”，这里仍存在完善的空间。研究小组计划通过观察处于风道中强气流�的蜘蛛进一步改进这一模式。
