More complex methods such as frequency weighting and frequency normalization go beyond the scope of this article. 更复杂的方法,比如频率加权和频率归一化,超出了本文范畴。
Treatment of Complex Metal Ions for Weighting the Silk Fabric with Dioscorea Cirrhosa Extract 复合金属离子对薯莨提取液增重真丝的处理
The complex weighting vector at the reference frequency is evaluated using Genetic Algorithm to make the array response cater for the pattern specified. 采用遗传算法对参考频率上的复数权向量进行设计使阵列响应满足给定的方向图要求。
The shape functions of the novel acoustic infinite element are the same as in paper [ 1], while the weight functions are defined as the product of the complex conjugates of the shaped functions and an additional weighting factor. 这种无限元方法使用文献[1]中无限元的形函数,权函数为形函数的共轭,再乘以一个附加权因子,这样求解过程就避免了无穷的指数积分。
Re-fracture of complex strong roof and its control in initial weighting period 复合型坚硬顶板在初压期间的再断裂及其控制
The complex weighting vectors at other frequencies satisfying the request of wideband constant beamwidth can be deduced from the one at the reference frequency. 其它频率点上满足宽带恒定束宽要求的复权向量可以根据参考频率上的复数权值通过折算求得。
In the TD-SCDMA standard, the principle and realization of complex spectrum spreading, weighting factor for Walsh code, and dedicated complex scrambling code are even adopted. TD-SCDMA系统更是采用了复扩频和Walsh码加权因子、专用复扰码的应用理论和实现方案。
