check sample的用法和樣例：
例句
- Part of the investigation may involve retesting of a portion of the original sample.
調查部分工作包括最初檢驗樣品的再檢驗。 - It should never be assumed that the reason for an outlier is error in the testing procedure, rather than inherent variability in the sample being tested.
決不能將出現逸出值的原因假定為檢驗操作的錯誤，而不認為被檢驗樣品存在固有的差異。
