解釋
超聲-
A method has been developed to calibrate the positions of the transducer and the transponder in the ultra - short baseline acoustic position system ( usbl )
摘要提出了超短基線水聲定位系統( usbl )的校準方法,並用模擬數據進行了驗證。 -
The emphases of our research works are as follows : under ultra - low temperature ( about 0. 236k ) conditions, how the frequency and power of the saw and the source drain voltage influence the acoustic current ; and the relationship between the source drain current and the split - gate voltage ; and how to find the cut off voltage of the quasi - 1d electron channel ; and also the frequency character of the idt in the saw parts
研究的重點為,在甚低溫( 0 . 236k )下,通過實驗研究表面聲波的頻率和功率,源漏偏壓等因素對聲電電流的影響;研究準一維電子通道中不同源漏電流與分裂門負偏壓的關系,以找到分裂門的鉗斷點電壓;以及研究聲表面器件叉指換能器的頻率特性等。 -
