Based on this opinion, the effect of dynamic trait loci could also be explained by inserting a Legendre polynomial in each genetic factor, and so the mathematic model for mapping dynamic trait loci was constructed.

把表型值随着时间(生命时期、年龄、胎次等)或其他可以量化的因素(生理状态、生产水平、代谢率和环境条件等)变化的性状称为动态性状。

The calculating formula of parabola and the length of ellipse arc can be found in the old handbook of mathematics, but it is inconvenient to be used in practice, especially, the accurate value is too difficult to get to.

关于抛物线和椭圆弧长的计算公式在数学手册和有关用表中早就可见。但实际上用起来很麻烦,其精确值也较难达到。

The different width and length of Hilbert curve geometries were investigated by finite element method. The computation results show that the DGS rejects the signal at two frequencies 2.43 GHz and 7.11 GHz from 0~9 GHz with more than -15 dB suppression. Q factors of the Hilbert curve DGS is bigger than that of conventional DGS.

通过有限元法对不同Hilbert曲线宽度和长度的DGS结构微带线进行计算,计算结果表明,该结构在0~9 GHz频段内表现出2.43 GHz和7.11 GHz这2个谐振频率,对应频率的通带反射损耗低于-15 dB,并且阻带特性在谐振频率处比传统DGS微带线有更高的 Q 值。
