The vibratory power transmission and reflection coefficients are determined as the function of radian frequency and coupled angle. 反射和传播系数确定为振动频率和耦合角度的函数。
△ W is the radian frequency deviation from the center frequency. Gene frequency The proportion of an allele in a population in relation to other alleles of the same gene. △W是角频率与中心频率的偏离值。基因频率:指某一特殊类型的等位基因在群体中所有等位基因总数中所占的比率。
The success rate of the first attempt using retro bent radian method was significantly higher than that using the routine method, with low frequency of re implantation. 逆弯曲弧度法置入胃管一次成功率显著高于常规法,且反复置入率低。
