1·Be warned, 240-hertz sets are the worst offenders.
特别240赫兹电视机是显示效果最差的。
2·No ifs and buts, at absolute zero temperature, this is exactly 9, 192, 631, 770 hertz.
这个频率不存在“如果和但是”，绝对零度的条件下，9192631770赫兹，不会有任何偏差。
3·It is one over T, and so the units are seconds minus one but most physicists would call that "hertz."
它等于T分之一，单位是秒的负一次方,大部分物理学家叫它赫兹
4·So if now I hang on it a mass of one kilogram, I can calculate the period of one oscillation, and one over the period F is the frequency F, and I believe that is something like 38 hertz.
如果在上面,悬挂1公斤物质，我能够计算出,振荡的周期，1除以周期,等于频率，我相信,等于大概38赫兹。
5·Every Hertz location has a person responsible for lost items, and about 75% are returned to their owners, she says. Unclaimed items are donated to charity.
赫兹每个租车点上都有一名员工专用负责失物，约75%的失物物归原主，她说。无人认领的被捐赠给慈善机构。
