Multiple layer control

But this design seems to conflict with the convenience layer goal, which is to focus on the feature, where one feature might control multiple XML elements.

但是，这种设计看起来与便利层的目标冲突，便利层主要关注文档特性，一个特性可能控制多个xml元素。

An active and passive hybrid damping control manner with lower voltage is proposed through both multiple piezoelectric patches and constrained damping layer for suppressing structural vibration.

提出一种用多层压电片和约束阻尼层在低控制电压下进行结构振动的杂交阻尼控制方式。

The formula of actuating force produced by multiple piezoelectric patches and the control equations of multi layer beam are derived based on the constitutive relations of different materials.

基于各种材料的本构关系，导出了多层压电片作用在梁结构上的力和所施加的电压以及结构的运动之间的耦合关系和系统的控制微分方程。
