The stability of the interface between two-layer fiber flow is essential for getting high quality multi-formation and layer purity. Some measures of keeping the stability of interface are got from theoretical analyse. The measures is close reducing the velocity difference between two layers; putting the fiber of lower density on the upper layer and the fiber of relatively higher density on the lower layer; and using low pulsation pump as the pumping equipment.

两层叠加流动的界面稳定性对多层成形的质量及层间纯度有重要影响，本文通过采用小扰动法对流动界面的稳定性分析认为，减小层间速度差；把密度较大的纸浆置于下层，密度较小的纸浆置于上层；以及采用低脉冲泵作为上浆泵均有利于保持层间流动界面的稳定性。

Periodic fluid pulsation in aeroplane hydraulic piping could induce fluid-construction vibration and lead to fatigue damage. It is impossible to find the error sensor's optimization location because of the pressure standing wave, and the pulsation attenuation effect is not perfect when adopting pulsation attenuation at single point. For this reason, a distributed active control method of fluid pulsation was presented. To avoid stationary point in all aviation states, several fluid pulsation actuators and error pressure sensors were placed along the piping. The second fluid pulsation produced by actuators can counteract the primary pulsation brought by aviation piston pump and make the mean pulsation of whole piping minimum when adopting adaptive feed- forward control and the filtered-X least mean square algorithm.

针对飞机液压能源管路系统中的周期性流体脉动诱发流固耦合振动，导致管路疲劳损伤的问题，针对管路中存在压力驻波特性，在采用单点消振时寻找误差传感器最佳布局位置困难而引起脉动抑制效果不理想的缺点，提出了一种分布式流体脉动主动控制方法，即沿管路不同位置布置多个主动消振阀和误差压力传感器，在任意飞行阶段，避开压力驻波点，以误差压力传感器的脉动测量值为控制目标，采用一种针对周期脉动主动控制的自适应前馈控制法和多通道自适应滤波－X LMS算法，调整控制器参数，使主动消振器产生的次级脉动与管路中的初始脉动相互抵消，达到整个管路中的平均流体脉动最小的效果。

G Single-Screw Pumps is an enclosed screw pump with inner gearing, a kind of rotor positive-displacement pump.
