查询词典 nucleon number

In order to reduce calculation error, the frequency distribution of average values is used to compute the mixed distribution's digital features of each component distribution, thereinto, the number of the component distribution is determined by AIC, choose the number that meets the minimum value of AIC as the component number of mixed distribution, and the other parameters are estimated by EM algorithm; Secondly, because each component distribution is corresponding to a kind of major gene genotype, according to the values of the average and variance of the each component distribution, we can use the limit error of the normal distribution to plot each individual into the correspondent component distribution, namely into correspondent major gene genotype. Then we regard each major gene genotype as a treatment level of one-way analysis of variances, and the one-way multivariate analysis of variance is carried out to calculate the covariance matrix of major gene effect, covariance matrix of polygene effect, covariance matrix of environment effect and so on; At last, combining the weights of the each component distribution of mixed distribution, we can calculate the variance of major gene effect, the variance of polygene effect, environmental variance and the genetic gain of the quantitative trait.

为减小计算误差，本研究采用均值的频数分布来计算各成分分布的数字特征，其中成分分布个数根据AIC准则，选择使AIC值达到最小的成分分布个数作为混合分布的成分分布数，分布中其它参数的确定利用EM算法来估计；其次，每个成分分布对应一种主基因基因型，根据各个成分分布的均值和方差，利用正态分布的极限误差将每个个体划分到相应的成分分布中，即相应的主基因基因型中，将每种主基因型作为单因素方差分析的一个处理水平，对其进行单因素的多元方差分析，分别计算主基因效应协方差阵、多基因效应协方差阵、环境协方差阵等参数；最后结合混合分布中各成分分布的权重即各主基因基因型的分离比例，计算主基因效应方差，多基因效应方差和环境方差，以及遗传力等参数，进而计算该数量性状的遗传进展。

In a typical implementation, the range is determined by the number of bits used in the exponent, and the precision by the number of bits used in the mantissa (giving the maximum number of significant digits that can be exactly represented).

在一个典型的实现中，范围是由用于表示指数的二进制位数量所决定，而精度是由用于表示尾数(给出了可以精确表示的有效数字的最大位数)的二进制位数量所决定。

Anti-B220/anti-IgM antibodies were used to analyze number and maturation of central and peripheral B cells in transgenic mice. It is found that number of mature B cells decreased in bone marrow, spleen, peritoneal cavity. B cells in bone marrow of Tg mice were just one half of that of control, and in spleen, this number was even one third of that of the control.

以anti-B220/anti-IgM抗体分析了转基因小鼠中枢和外周B细胞数的变化及成熟情况，发现骨髓、脾和腹腔的成熟B细胞数都明显下降，其中骨髓和腹腔约为对照野生鼠的一半，而脾更低至三分之一。
