从理论上讲，这样会稍微削弱保护能力，但是这种默认行为改进了性能，同时仍然能够防止大多数问题。
In theory, this could weaken the protection slightly, but this default improves performance while still protecting against most problems.
这是因为底漆涂布得太广也会导致干燥后的漆膜过薄，从而反过来削弱它的主要性能。
This is because the primer coating is too wide can lead to drying of the film too thin, which in turn weaken its main properties.
同时，通过削弱量化误差以及在设定点附近引入PI补偿控制器，提高了系统的动态、静态性能指标。
The dynamic and static performance index is greatly improved through decreasing quantization errors and combining with PI controller that operate nearby set point.
