Mr Frayn frankly admits that he is no expert in the field and must rely on popular accounts of which he understands only a fraction.

弗莱恩坦言他并非量子力学领域的专家，必须依赖量子力学的一些通俗解释，而即使是这些通俗解释他也仅能理解一部分。

Since a magnetic field changes the resistance of ordinary metals by only a fraction of a percent, they dubbed this phenomenon "giant magnetoresistance, " or GMR.

由于磁场变化对普通金属只会造成远远不到百份之一的电阻变化，这种现象被称为“巨磁电阻”或巨磁阻GMR。

As a result, field trials with these plants are 10 to 20 times as expensive as experiments with virtually identical plants modified with less precise, conventional techniques, so only a minuscule fraction of potentially important plants developed in university and corporate laboratories ever make it into field trials.
