If something is systematic, it is done in an organised, step-by-step way, following a plan, with nothing skipped. A systematic search means you look at every room in order rather than wandering about; a systematic study means the researchers followed a fixed method all the way through. It suggests care, thoroughness and method, and in schoolwork or science it is praise.

If something is systematic,如果某件事情是systematic的 it is done in an organised, step-by-step way,那表示它是用有組織、一步一步的方式做的 following a plan, with nothing skipped照著計畫走，什麼都不跳過。A systematic search means you look at every room in order rather than wandering about;systematic search（有系統的搜索）指的是你按順序檢查每個房間，而不是到處亂逛 a systematic study means the researchers followed a fixed method all the way throughsystematic study（有系統的研究）指的是研究者從頭到尾都遵循固定的方法。It suggests care, thoroughness and method,它暗示著細心、徹底、有方法 and in schoolwork or science it is praise在課業或科學上這是一種稱讚。

Here is the part dictionaries often leave out. 'Systematic' also has a colder use, where it describes something bad that is done in an organised way over a long time and on purpose — systematic abuse, systematic corruption, the systematic destruction of a city. The organisation is exactly what makes it frightening: it was not an accident, someone planned it. So the word itself is neutral; the feeling comes from what follows it.

Here is the part dictionaries often leave out這是字典常常沒講到的部分。'Systematic' also has a colder use,『systematic』也有比較冷酷的用法 where it describes something bad that is done in an organised way over a long time and on purpose用來形容某件壞事是經過長時間、有計畫、有組織地進行的 — systematic abuse, systematic corruption, the systematic destruction of a city像systematic abuse（有系統的虐待）、systematic corruption（有系統的貪腐）、the systematic destruction of a city（有計畫地摧毀一座城市）。The organisation is exactly what makes it frightening:正是這種組織性讓它令人害怕 it was not an accident, someone planned it這不是意外，是有人計畫好的。So the word itself is neutral;所以這個字本身是中性的 the feeling comes from what follows it感覺是來自它後面接的東西。

There is a second, narrower meaning in science: 'systematic' can mean 'to do with a system of classification' — systematic botany is the study of how plants are grouped. And in measurement, a 'systematic error' is an error that repeats in the same direction every time because of a fault in the method, as opposed to a random error.

There is a second, narrower meaning in science:在科學上還有第二個比較狹窄的意思 'systematic' can mean 'to do with a system of classification'『systematic』可以指『跟分類系統有關』 — systematic botany is the study of how plants are grouped像systematic botany（系統分類植物學）指的是研究植物怎麼被分類。And in measurement, a 'systematic error' is an error that repeats in the same direction every time because of a fault in the method,而在測量上，a 'systematic error'（系統性誤差）指的是因為方法有缺陷、每次都往同一個方向偏的誤差 as opposed to a random error跟random error（隨機誤差）不同。
