FPF abbr. 胎儿肺液(fetal pulmonary fluid)
- The whole process of stiffness analysis, up to the point of FPF(first Ply failure) for laminates under multiaxial loading is given as well.
完成了玻纤复合树科层合板在复杂载荷下直到FPF(第一层破坏)发生时的非线性响应和刚度分析的全过程。 - Finally, a remarkably improved transmission performance of the EG-FPF is obtained by thinning the substrate down to a suitable thickness range through well-controlled grinding and polishing.
最后,在实验上通过对衬底的研磨和抛光,将其减薄到一定的厚度范围内,从而使得该滤波器的传输性能得到极大改善。 - Analyxed the injury accidents relating with the friction press of firebrick (FPF) , the author developed a new practical safety apparatus for FPF, which can effectively reduce such accidents.
