From the view of the mathematic theory,it is testified that the heap type network is(submitted) to idempotent law transformation theorem,on the time sensitivity it is prior to single bus type network in .
基于CSMA/CD总线优先级控制的堆叠式网络,将堆叠式网络抽象为一种r级网络数学模型,从数学原理角度对堆叠式网络结构服从幂率变换定理,在其时间敏感性上以幂率收敛方式优于单总线型网络进行了证明。
4) circle theorem
圆定理
1.
advanced the circle theorems by surface source distribution,and tried to apply it to the research of circulation controlled airfoil,and gained a closed form analytical solution.
Rand(1989)[1]提出面源分布的圆定理,试图将它应用于环量控制翼的研究,并获得了理论解。
6) semicircle theorem
半圆定理
1.
A semicircle theorem on the spectral distribution in transverse instability perturbation is derived.
作者在理论上对不稳定横波型扰动的谱点分布作了分析,得到了该不稳定扰动谱点分布的半圆定理,即谱点分布在复平面上以原点为圆心 以R0为半径的下半圆域上;并发现扰动的波长越短、模式层顶越高、静力稳定度参数的绝对值越大、基流的垂直切变越大、纬度越高则该半径就越大。
2.
The semicircle theorem on the spectral distribution in symmetrical instability with Wave-CISK is obtained.
采用滞弹性近似研究了WAVE-CISK下对称性扰动的谱点分布,得到了WAVE-CISK下对称不稳定扰动谱点分布的半圆定理,用其可估计该对称不稳定增长率的上界。
补充资料:圆幂定理
过平面上一个定点m,任作一直线与半径为r的定圆交于a、b两点,则ma·mb为定值k,且等于om2-r2。定值k称为点m对圆o的幂,简称“圆幂”。上述命题称为圆幂定理。圆幂定理包括相交弦定理、割线定理和切割线定理。
