tension field的用法和樣例：
例句
- The more general case of a tensor field is similar but more complicated.
較普遍的張量場(chǎng)情況大致相似，但是更為復雜。 - But if the field changes or oscillates quickly enough, it produces a gravitational attraction, just like ordinary or dark matter.
不過(guò)，要是純量場(chǎng)變化或是振蕩得夠快，它就會(huì )產(chǎn)生重力相吸效應，一如普通物質(zhì)或是暗物質(zhì)。
