杂交试验中的最佳样本含量

杂交试验是一项费时费钱的工作，因此在进行试验之前如能进行严密的设计，给出试验所需的样本大小是十分必要的，统计学中常见的估计样本容理的公式不宜应用于杂交试验，本文分两种情况给出了杂交试验中样本容量的估计公式，据此估计出的样本容量安排杂交试验，可在满足试验者要求的条件下，使试验的总成本最低或使试畜的总头数最少。

Optimum Sample Size in the Crossing Experiments

Crossing experiments are time-consuming and costly, hence, it is very essential to make a through plan and provide the necessary and sufficient sample size in advance. The common formula of the sample size in statistics is not suitable for the crossing experiments. This paper discussed two cases and put forward a corresponding estimate formula of sample size for crossing experiments, by utilizing the sample size derived from the estimate formula to arrange the crossing experiments; thus the total experimentation cost could be reduced to the lowest, or the total number of tested livestocks may be the fewest under the precondition of satisfying the requirements of the experiment designer.
