That in itself is a stunningly infinitesimal proportion.

本身就是个极其微小的部分。

It was the united products of infinitesimal vegetable causes, and these were neither stems, leaves, fruit, blades, prickles, lichen, nor moss.

它是细小植物共合成的，些植物不是树干草茎，叶柄叶片，也不是实棘刺，青苔绿薛。

In point of fact the three actions of perceiving, determining, and responding were sequential; but so infinitesimal were the intervals of time between them that they appeared simultaneous.

说句实在话, 从发现情况到进行判断到作出反应本是一个连贯的行为, 但在他身上表现出来的间隔时间太短了, 以至于成了时发生的了。

But Voldemort broke off: Harry heard a scuffle and a shout, then another bang, a flash of light, and grunt of pain; he opened his eyes an infinitesimal amount.

但是伏地魔被打断了，哈利听到了一阵騷乱，后是另一声巨响、一束亮光和痛苦的呻吟。他把眼睛睁开了一个小缝看了看周围。

Yet we take it for granted that your ears can capture that infinitesimal signal and use it to signal to the brain the full range of auditory experiences: the human voice, music, the natural world.

但我们都理所地觉得耳朵能捕捉到个微乎其微的信号，并将丰富的听觉体验传递给大脑：人声，音乐，大自的声音。

He crouched down beside Harry, who saw, through the infinitesimal gap left between his swollen eyelids, a face covered in matted gray hair and whiskers, with pointed brown teeth and sores in the corners of his mouth.

他在哈利身边蹲下来，哈利透过膨胀的眼皮之间留下的极小缝隙看到一张长着褐色尖牙，嘴角溃烂，覆盖着毫无光泽的灰色头发和络腮胡子的脸。

It happened in a fraction of a second: in the infinitesimal pause before Dumbledore said 'three', Harry looked up at him - they were very close together - and Dumbledore's clear blue gaze moved from the Portkey to Harry's face.

在邓布利多数到" 三" 之前那短暂的停顿中，哈利抬头看了他一眼--　他们离得很近，邓布利多清澈的目光从门钥匙移到哈利的脸上。
