外直肌
线性回归模型
相似比例法
Examples
- Linear referencing system ( lrs ) provides the fundamental referencing space for transformation among various linear referencing methods ( lrm ) and supports multiple cartographic representations ( at any scale ) , which presents a good way of integrating and sharing data in gis - t
摘要线性参照系统在gis - t中提供了一种数据集成与共享的方法，可实现多种线性参照方法间的相互转换及在任意比例尺的地图上进行绘图显示。 - The implementation of such a system is extremely complicated due to three factors : the impulse response of a lrm system have a duration of several hundred milliseconds , the system has to be adaptive , and the adaptation has to be performed with a speech input the traditional adaptive algorithms such as lms and nlms can not obtain the satisfied result in the real - time acoustic echo cancellation processing
但由于声回授通道的特殊性和复杂性，普通的自适应算法无法满足要求，必须采用一些十分复杂的算法，这样一来，实时性的问题变得十分突出。快速lms newton算法的提出，给自适应声回波对消问题的解决开辟了新的途径。该算法集lms算法的简单易行性和newton算法的快收敛性为一体，是一种非常有应用前景的自适应算法。 - Adaptive echo cancellation provides a comfortable solution whose concept is extremely simple : if an exact electric replica , parallel to the lrm ( loudspeaker - room - microphone ) system is provided , the decoupling of loudspeaker and microphone can be achieved without any restrictions to the electric acoustic system and - more important - without any loss of convenience to the user
为解决声回波对消问题( aec ) ，人们提出了各种方案，传统的方法能在一定程度上抑制回声，但存在抑制比较小，或需要专用房间，限制通信者移动等缺点。不能给通信者提供?个完全舒适的通话环境。
