子代全称是： filial generation ，所以用“F“ 表示，就和亲代一样，亲代全称是： parental generation ，所以用“P”表示

P表示亲代，F表示子代，其中F1为子一代，F2为子二代，以此类推。这是遗传图解中的基本表示符号，英文中亲代译为Parental generation;子代译为Filial generation.取英文首字母即为P和F。
We present the results of a search for pair production of a fourth-generation charge -1 / 3 quark (b') in sqrt[s] = 1.8 TeV p{ovr p} collisions using 88 pb of data obtained with the Collider Detector at Fermilab. We assume that both quarks decay via the flavor-changing neutral curr...
【摘 要】涡旋波束的中空发散特性,导致其远距离传输下接收困难。且传输信道中的多径效应会造成涡旋波束的相位畸变和模态间干扰问题,影响涡旋电磁波信号的传输质量。针对上述问题,建立了基于部分孔径取样接收方案的稀疏多径涡旋电磁波无线传输模型,...

The mechanisms underlying the organization and evolution of the telencephalic pallium are not yet clear.. To address this issue, we first performed comparative analysis of genes critical for the development of the pallium (Emx1/2 and Pax6) and subpallium
