vector quantity 有向量。

vector sum

Compared with the pressure hydrophone , vector transducer can provide both the information about pressure ( scalar quantity ) and particle velocity ( vector quantity ) of the sound field , which offers more possibilities for signal processing . so vector transducer and its signal processing have attracted the attention of researchers both native and foreign . in this thesis , a method of correlation equations for pressure gradient transducer is presented , and the estimation of multi - signal parameters with single vector transducer is given 與傳統的聲壓水聽器相比,矢量水聽器既能獲得聲場中的聲壓這一標量信息,又能獲得聲場中質點振速這一矢量信息,這為其信號處理帶來更大的空間,因此矢量水聽器及其相應的聯合信息處理技術日益成為國內外科技工作者們研究的熱點。

It synthesizes the excellence of wave coding and parameter coding , adopts vector quantity , analyse - synthesize , perceptual weighting , therefore , gains good speech coding quality at 8kbit / s . cs - acelp can be used in individual telecom , iphone , c / n , microwave telecom and isdn Cs - acelp算法綜合了波形編碼和參數編碼的優點,以自適應預測編碼技術為基礎,采用了矢量量化、合成分析和感覺加權等技術,在8kbit / s速率上獲得了較高的語音編碼質量。

3 . use characteristic vector quantity of normal situation with leak characteristic vector quantity of situation compare , adopting valve method determinant the leakage of pipelines 本文應用正常情況下的特征向量與泄漏情況的特征向量進行比較,并且采用閥值的方法判斷泄漏故障的發生。

A vector quantity whose magnitude is a body ' s speed and whose direction is the body ' s direction of motion 速度一種向量,其量值為物體的速率,其方向為物體運動的方向
