Thesis English Abstract: Do One Back-Translation After Writing It and You Can Catch Half the Problems
My English abstract read smoothly, but my advisor took one look and said, “The Chinese sentence doesn’t mean that.”
I wasn’t convinced, so I ran the English abstract through Youdao Dictionary back into Chinese—it didn’t read like my original Chinese abstract.
The problem lies in that “didn’t read like.”
What Is Back-Translation
Back-translation: translate the English you wrote back into Chinese and compare it with the original Chinese abstract.
The differences that emerge are either “meanings the English failed to express” or “meanings the English added.”
It cannot prove that the English is idiomatic, but it can prove that the English has not drifted.
The Four-Step Method
1. Finalize the Chinese abstract and don’t change it yet
2. Translate it independently into English (without looking at the Chinese; write from memory to avoid Chinese-style literal translation)
3. Translate the English back into Chinese
4. Compare the two Chinese versions sentence by sentence and mark the differences
The fourth step is the key, and it is also the step most easily skipped.
Differences Fall into Three Categories
| Difference | Description | How to fix |
| Meaning changed | The back-translation differs from the original meaning | Revise the English |
| Meaning missing | The back-translation loses qualifiers or metrics | Add it to the English |
| Meaning added | The back-translation contains a judgment not in the original Chinese | Delete it from the English |
The third type is the most dangerous:what gets added is usually a “more absolute” word, such as translating “有所提高” as improved.
A Real Example
Original Chinese sentence: “The process showed relatively good stability at low temperatures.”
My English: The process shows good stability at low temperatures.
Back-translation: “The process has good stability at low temperatures.”
It looks about the same, but “relatively good” became “good”—the comparative sense disappeared.
After changing it to “relatively good stability,” the back-translation showed “relatively good,” and only then did it match.
The Three Places in an Abstract Most in Need of Back-Translation Checking
1. Conclusion sentence: this is where others cite you
2. Values and units: an error here is a serious flaw
3. Limiting conditions: temperature, sample, conditions—none can be omitted
Beyond these three places, grammar and word choice can be run through MuchSci, but you must check these three places yourself.
Limitations of Back-Translation
Back-translation cannot guarantee idiomatic English. It may read right when translated back into Chinese, but the English may still be Chinese-style phrasing.
So after back-translation, I also do the opposite: read the English abstract on its own and look for “long sentences with Chinese word order.”
Only after doing both checks does it pass.
How I Did It
For the back-translation step, I used MuchSci’s paper translation: I translated the English abstract back into Chinese and viewed it side by side with the original, so the differences were obvious at a glance.
MuchSci’s paper translation supports both Chinese-to-English and English-to-Chinese, so I don’t need to switch tools when translating back and forth; after revising, I translate it again to confirm the differences are gone.
A Little Takeaway
Most problems with English abstracts are not “bad English” but “Chinese and English not corresponding.”
Back-translation solves the correspondence problem. It takes less than twenty minutes, but it can save you from the awkwardness of “reviewer asks what this sentence means.”
