Physicists call such phenomena "emergent" because they depend on a multiplicity of relatively simple interactions.

物理学家管这样的现象叫作“突现”；“突现”其实是大量相对简单的反应相互叠加作用的结果。

These two properties define what physicists call the "figure of merit" of a thermoelectric substance, which describes the power a device made of that substance could generate.

这两种属性决定着热电材料的“品质因数”。“品质因数”是用来描述用热电材料所制成的元器件的输出功率的单位。

Although in this case the waves are not in the visible spectrum, physicists still call the stretching and shrinking of the waves red-shift and blueshift, respectively.

虽然这种情况下电磁波的波长不在可见光的范围内，物理学家仍旧分别称波的红移和蓝移为“伸长（Stretching）”与“收缩（Shrinking）”。

More powerful particle accelerators atom smashers, they used to call them have allowed physicists to learn ever more about the sub-atomic particles that are the basic building blocks of all matter.
