instantaneous sampling meaning in Chinese

瞬间采样
瞬间取样
瞬时采样

As the kernel of software , the algorithm is another emphasis of the paper ' s works . based on the principle of relaying working , after comparing the effect between the algorithm of instantaneous sampling and the algorithm of vector , the virtue of short data windows and precision action was stood out . and the choice of algorithm with three sampling data was for the reason of short data windows
算法理论作为微机保护的软件核心也是本文的讨论重点，以保护的动作原理为基础，认真研究了采样瞬时值法与一般的矢量值法的效果比较，突出了采样瞬时值法时间窗短、动作准确的优点；而针对低电压闭锁所采用的三采样值积算法也正是出于时间窗较短，便于配合保护动作的考虑。
