sound velocimeter

基本解釋

PAN fibers with different drawing ratio and different preoxidation degree were investigated by means of sound velocimeter and X-ray diffraction meter.
采用聲速儀及X射線衍射儀對(duì)不同牽伸倍數(shù)和不同預(yù)氧化程度的PAN纖維進(jìn)行取向度和預(yù)氧化程度的測(cè)試，并將其結(jié)果進(jìn)行對(duì)比。
The structure and design of hardware and software of the digital fiber sound velocimeter, which based on the digital signal processor MC68VZ328, are explained in details.
詳細(xì)闡述基于MC68VZ328的數(shù)字式纖維聲速取向度測(cè)量?jī)x的軟、硬件設(shè)計(jì)。
