1) relative frequency
相对频率
1.
Experiment research of visual performance feedback of different relative frequency to motor skill learning;
不同相对频率的视觉表现反馈对运动技能学习效果影响的实验研究
2.
according to the first statement that a relative frequency is a probability; according to the second statement that relative frequency and probability are two distinct concepts; probability is dependent on the observers, while relative frequency is not dependent on the observers.
概率的定义有两种稍微不同的陈述方式 ,按照第一种陈述 ,相对频率就是概率 ;按照第二种陈述 ,相对频率与概率是不同的概念 :概率依赖于观察者 ;相对频率则与观察者无关。
3.
It is found that there is a good linear relation between the logarithm of 6 base mode number and its relative frequency (RF); most 4 base modes and 3 base modes are in the region of RF<2 .
对大肠杆菌基因 1 2 3 1个编码开始区域和 1 3 0 7个编码终止区域内的 6碱基片段、4碱基片段和 3碱基片段进行了统计 ,发现 6碱基片段模式数的对数与其相对频率成线性下降关系 ,绝大多数 4碱基和 3碱基片段出现在相对频率小于 2的范围之内 ;编码区出现最多的碱基片段是多聚A ;编码开始区域和编码终止区域的碱基构成模式有明显区别 ;编码开始区域里GGA类的稀有片段恰恰是SD区域最偏好的碱基片段 ;密码子之间 ,以TAG或CTA构造的关联模式为编码区禁用模式 。
