积性函数 [
jī xìng hán shù]
[数] multiplicative function
- 计算阻抗矩阵元素时,由于被积函数振荡性很强,收敛慢,难于计算。
The integrand exhibits slowly convergence and highly oscillatory, which leads to difficulties when attempting to evaluate the impedance matrix elements. - 对称积分区域以及被积函数有与之相匹配的奇、偶性的积分,均可用对称性简便计算。
The integration can be simplified calculated using symmetry if it has symmetric integral domain and its integrand has odd or even characteristic. - 对于模糊数值函数的积分原函数的可导性问题,本文构造性地给出一反例。说明存在(K)可积的模糊数值函数其积分原函数并不是几乎处处可导的。
In this paper, an example is given. It shows that there exists a fuzzy-valued function which is (K) integrable on [a, b], but its primitive is not differentiable almost everywhere in [a, b].
