There is a certain deviation of testing result of sulfide compouds when salt concentration (or salinity) is above 30‰.

There is error in sulfide test result when salinity exceeds 30%

What is the menaing of "一定偏离"?

"一定“means"to a certain degree"or"在一定程度上”in Chinese

In metrology, we generally use the term “accuracy” to describe the test method/result qualitatively (or use the terms “trueness” and “precision” quantitatively) (see ISO 5725-1 Accuracy (trueness and precision) of measurement). Furthermore, error always exists no matter the salinity is higher or lower than 30‰. Therefore, does the sentence “当盐度大于30‰时，硫化物的测定结果存在一定偏离” eventually mean “当盐度大于30‰时，硫化物的测定结果有較大的偏离”?



If positive, I suggest:

There would be a larger (significant, excessive or considerable etc.) error in sulfide test result when salinity exceeds 30‰ .
or
The result of sulfide test would be less accurate when salinity exceeds 30‰.

.

Thanks.Your answer is probably the one I need compared wth all above which seems to be Chinglish rather than translation

You are welcomed.

我不是主修化学的, 所以没有symmacros的回帖我就不知“盐度”的英文是salinity;对“偏离”一词, 我本来也会译成deviation,但看了rock_rock的回帖, 觉得error更贴切。

在这论坛, 大家互相帮助很平常。 不少的求助者也都很有礼貌, 无论回帖的建议是否接受, 结帖时对所有回帖者道谢。
