Deduced by the proportion of typical sterile plants and normal fertile plants in segregative generations derived from WA zhenqiuA/6078 that:I gene could inhibit the expression of Rf gene completely by the heterozygosity of 1 pair of Rf in genotype;and only reduce the expression of Rf genes with two heterozygous Rf genes in genotype ;but it would never inhibit the expression of Rf genes if the genotype included 3 pairs of heterozygous Rf genes. When Rf gene was homozygous,the / gene could not inhibit the expression of it.

根据认叭真秋刀6078各衍生分离世代中典型不育株和正常可育株所占比例推断：基因型中仅包含1对杂合的Rf基因时，I对Rf的表达起完全抑制作用；基因型中包含2对杂合的Rf基因时，I仅对Rf的表达起削弱作用；当基因型中包含3对杂合的对基因时，I对Rf的表达不起抑制作用；I对纯合位点的Rf的表达不起抑制作用。

RF：射频

電子學,聲頻電路上所謂"阻抗匹配"良好,不是指放大器的輸出阻抗(Zo)=負載電阻(loading)而是應該Zo遠小於負載,這樣才能作出良好的匹配.不至產生失真.在高頻與射頻(RF)下探討阻抗匹配(Impedance Match)那與音頻是完全不同的世界!

RF：无线电频率

为客户提供令人叹为观止的游戏动画图形效果,及如FM广播、双重VGA显示器支援、比实时还快(Faster-than-Real time)的DVD/CD光盘编写等精彩特性,此外还可支援新一代「REMOTE WONDER II」无线电频率(RF)遥控器.

RF：间苯二酚-甲醛树脂

采用乳液共混法制备了淀粉/丁苯橡胶(SBR)以及间苯二酚甲醛树脂(RF)改性淀粉/SBR复合材料,考察了偶联剂对2种复合材料硫化特性、力学性能的影响,并用扫描电镜观察了其相态结构.结果表明,各种偶联剂都能在一定程度上提高淀粉/SBR复合材料的拉伸强度和撕裂强度,

RF：流量

经肘静脉灌注对比剂,同时开始持续46S的单层连续动态扫描,重建46幅动态图像使用CT脑灌注软件包进行处理,获得灌注成像.计算最大峰值时间(PT),平均通过时间(MTT)和相对血流量(RF).结果:早期常规CT头颅平扫,
