repetition method

Study and test showed that both EGME and ethylene blue analysis are reliable and accurate for specific surface area determination with good repetition, particularly ethylene blue analysis is an easy and cheap method.

试验研究表明，EGME法和亚甲基蓝法均是重复性好、准确可靠的泥页岩比表面测定方法，尤其是亚甲基蓝法简便易行，成本较低。

The third chapter discusses repetition. It is a very useful method to the application of the theory of spatialized time.

第三章论述重复，这是运用空间化的时间理论的有效方法之一。

This paper presents a method extracting target acceleration by using discrete Wigner-Ville distribution under low pulse repetition frequency ( PRF) and a finite number of samples, velocity information ( Doppler frequency) of target can be obtained simultaneously by using the time-frequency analysis method.

提出了一种在低脉冲重复频率（PRF）和对目标采样数有限情况下提取加速度信息的方法。用这种离散时频分析方法同时也能获得目标的速度信息（多普勒频率）。

It indicates from the experiment results that the stability of laser has been highly enhanced when running with high repetition frequency after using this novel Q-switched method, and it effectively solved thermal depolarization effect, improved output ratio of Q-switching to free running.

实验结果表明，采用这种方式后，在重复频率工作时较大的提高了激光输出稳定性，有效地解决了热退偏效应，提高了调Q动静比。

The results showed that this method had good selectivity, celerity, stabilization and repetition.

此方法选择性好, 常温下反应快速 、 完全且稳定,重复性很好.
