A study of phase property of selective shaped pulses in combination with PFG

Based on the above research, a set of long-pulse accelerator with helical PFL is built.

在上述工作的基础上，研制了一台单线结构的水介质螺旋线型长脉冲加速器，这种加速器在国内外还未见报道。

This made the mechanical recovery well having a misleading appearance of higher producing fluid level ( PFL).

这种现象使机采井存在动液面偏高假象等问题。

Reliable on-board launch ability is the precondition of executing the task of OTV ( Orbit Transfer Vehicle), which is a maneuvering platform.

OTV作为一种空间机动平台，可靠的在轨发射能力是实现其任务使命的重要前提条件。

The application of OTA and OTV will improve the influence of TA saturation on main equipment protection.

光电流互感器（OTA）、光电压互感器（OTV）的应用，将改善TA饱和对主设备保护的影响。

PFW was added based on PWM, and switching circuit between PWM, PFW and control circuit of external characteristic were designed, the control system fulfilled the higher request, and have double excellence of PWM and PFM.

在PWM控制的基础上引入PFM控制，并设计出PFM与PWM的切换电路及外特性控制电路，实现了设计的控制要求，使整个控制系统具有PWM和PFM的双重优点。

Through an analysis of crystal chemistry and sintered mechanism for PFW. it has been shown that addition of PFW to PZN can decreases or suppresses the formation of pyrochlore phase.

通过对PFW结晶化学和烧结机理的分析，证明在PZN中添加PFW能减少或抑制焦录石的形成。

When the content of PFW in Kevlar fabric composite is 20%, the Kevlar fabric composites can obtain the best friction-reducing and anti-wear properties.

当PFW质量分数为20%时，Kevlar纤维织物复合材料的摩擦系数减小75%、磨损率降低82%，Kevlar纤维织物复合材料的减摩抗磨性能最佳。
