在张网渔具最适网目试验中，如果直接使用套网法的试验结果制定最小网目，那么这一尺寸会偏大，造成部分鱼类过多释放。
If the minimal mesh size of stow nets is determined based on the result from the cover net method, the mesh size will tend to be bigger, resulting in excessive escape of the fish inside the codend.
盘式制动器的零部件比较多，但由于部分零件为异形不规则结构，并且需要定义的尺寸参数过多，不便于进行参数化设计。
The brake system has many parts, but some of them are irregular structure, and need to define too many size parameters, are not easy to make parametric design.
这就需要优化燃烧器的结构尺寸，再者，当空气量过多或超负荷下，发生离焰，导致燃烧恶化、火焰熄灭，需要有辅助火焰和钝体稳焰。
Besides, the excess air or excess load will cause flame lift, combustion exacerbation and flame off, and that needs auxiliary flame and flame retention by inactive substance.
