sample degradation造句

例句与造句

1. This allows for the use of low energy beam currents in HI-ERDA preventing sample degradation and excessive heating of the specimen.
2. The detector solid angle has to be closed, but the thick sample can take more current without heating, which decreases sample degradation.
3. Beside of the 20 positive samples, 34 were reported to have tested negative, and the remaining 30 samples were inconclusive due to sample degradation.
4. The results of these tests were published to have returned 44 positives and 9 negatives, with the remaining 7 samples not returning any result due to sample degradation.
5. However, the high photon flux can also cause sample degradation, and for this reason some setups require a thermally conducting substrate ( which acts as a heat sink ) in order to mitigate this process.
6. It's difficult to find sample degradation in a sentence. 用sample degradation造句挺难的
7. A problem in northern blotting is often sample degradation by RNases ( both endogenous to the sample and through environmental contamination ), which can be avoided by proper sterilization of glassware and the use of RNase inhibitors such as DEPC ( diethylpyrocarbonate ).
8. Non-contact mode AFM does not suffer from tip or sample degradation effects that are sometimes observed after taking numerous scans with contact AFM . This makes non-contact AFM preferable to contact AFM for measuring soft samples, e . g . biological samples and organic thin film.
