In order to obtain accurate indications of range, the linear sweep of the cathode-ray tube must be timed precisely. 为了精确地指明距离,阴极射线管的线性扫描必须计时准确。
Investigation radius is so-called the radial range that pressure wave can sweep sometimes at the out edge of the pressure drop funnel. 压降漏斗的外部边缘即某一时刻压力波所能波及到的径向距离就是所谓的探测半径。
Polyaniline ( PANI) was synthesized at Au electrode by potential scan and the effect of the range and sweep rate of potential-scan, the pH and the concentration of aniline on the permselectivity of polyaniline were studied. 采用循环电位扫描法在金电极上合成了聚苯胺膜,研究了电位扫描范围、扫描速度、溶液pH及苯胺浓度对膜的选择透过性的影响。
The range, stepped frequency and dwell time of sweep frequency could be set by software. 频率扫描范围,频率步进和驻留时间等参数可由软件设置。
