The results showed that:(1) we can mapping quantitative trait locus while estimating the variance component of QTL;(2) granddaughter design is better than daughter design when mapping QTL;(3) it is easy to map a QTL for trait with a high heriability and a large QTL variance contribution;(4) we can estimate the variance component of a QTL by TM-BLUP based on ML method whether the QTL has only 2 alleles or QTL has normal distributed alleles effects;(5) the estimation accuracy of variance component contributed by QTL was improved by using of grand daughter design;(6) the higher the heritability and the QTL variance contribution was, the more accurate estimation of QTL variance component.

结果表明：（1）采用随机QTL效应模型和最大似然法，在估计QTL方差组分的同时，能够定位QTL；（2）孙女设计与女儿设计相比，在其它因素相同时，容易检出QTL；（3）遗传力高，QTL方差贡献较大的性状，QTL检出的效果优于遗传力低，QTL方差贡献较小的性状；（4）无论QTL上有2个等位基因，还是QTL上等位基因的效应服从正态分布，都可将其看作随机效应，采用基于TM-BLUP的ML法，估计其方差组分和定位QTL；（5）QTL方差组分估计的准确性，孙女设计高于女儿设计；（6）遗传力高的性状，QTL方差贡献大的QTL，QTL方差组分估计的准确性高。

In a Word, I was so prepossess'd against my going by Sea at all, except from Calais to Dover, that I resolv'd to travel all the Way by Land; which as I was not in Haste, and did not value the Charge, was by much the pleasanter Way; and to make it more so, my old Captain brought an English Gentleman, the Son of a Merchant in Lisbon, who was willing to travel with me: After which, we pick'd up two more English Merchants also, and two young Portuguese Gentlemen, the last going to Paris only; so that we were in all six of us, and five Servants; the two Merchants and the two Portuguese, contenting themselves with one Servant, between two, to save the Charge; and as for me, I got an English Sailor to travel with me as a Servant, besides my Man Friday, who was too much a Stranger to be capable of supplying the Place of a Servant on the Road.

总之，我不想走海路已成了一种先入为主的想法，怎么也无法改变了；唯一我愿意坐船的一段路，就是从加来到多佛尔这段海路。现在，我既不想急于赶路，又不在乎花钱，所以就决定全部走陆路，而且陆上旅行实在也是很愉快的。为了使这次旅行更愉快，我的老船长又给我找了一位英国绅士为伴。此人是在里斯本的一位商人的儿子，他表示愿意和我结伴同行。后来我们又找到了两位英国商人和两位葡萄牙绅士，不过两位葡萄牙绅士的目的地是巴黎。这样，我们现在一共有六个旅伴和五个仆人；那两位英国商人和两位葡萄牙绅士为了节省开支，各共用一个听差。而我除了星期五之外，又找了一个英国水手当我路上的听差，因为星期五在这异乡客地，难以担当听差的职务。

By analyzing standard deviations of parameters' differences, it is found that the interdigitated method is indeed superior than the original. Besides, Vth and Muo are inversely proportional to the interdigit's finger numbers, especially the threshold voltage. Therefore, a model is proposed to predict the performance of the interdigitated method, which has high accuracy with the real data.

藉由分析元件参数差值的标准差，我们发现叉合方法比传统方法具有更优良的特性，其中位障电压与迁移率差值的标准差与叉合数目呈现反比，特别是位障电压，因此我们提出一个公式以准确预测叉合方法的效能。
