stopped pulse

The shortcomings of general pulse technique, tail gas technique and stopped-flow technique in catalytic research might be overcome by using pulse catalytic chromatograph branch-flow technique.

脉冲催化色谱分流技术克服了一般脉冲技术、尾气技术和断流技术等在催化研究方面的某些局限性，是一种改进了的微型脉冲催化色谱技术装置。

We stopped at a sandbank peppered with nesting holes, and watched the air pulse iridescent blue as hundreds of bee-eaters swooped around us.

我们在一块沙丘边停下车，只见上面密布巢穴，成千上万的食蜂戴胜鸟在飞落下来时，四周的空气都颤动着闪亮的蓝色。

Machinery slackened; throbbing feebly like a fainting pulse; stopped.

机器慢下来了; 震动得象微弱的脉搏那样无力; 最后停止了.
