The common methods to reduce the repetition rate of papers in the fields of science and engineering are:

First, pay attention to the use of synonym modification.

HowNet's duplicate checking rule is that 13 consecutive words will be marked in red, so you can modify sentences with words with the same or similar meanings, which can reduce the red marking of some papers.

Second, the form modification method.

If there are too many red parts in the test paper, we can integrate some data in the test paper and present them in the form of tables, so that the duplicate checking rate of the test paper is greatly reduced.

Third, although the topic is writing a paper on literature and history, you can also learn from the above two:

1, avoid whole paragraph reference. Although the ancient poetry is an independent chapter, the paper is not for editing and publishing these poems, and there is no need to quote the whole paragraph. We can disturb the word order before and after, or cross-quote two poems. The repetition rate naturally decreases.

2. If you quote poems for comparative analysis, you can draw a chart and embed the poems in the chart to avoid repetition.
