Thus when the digestiontime was decreased in the spectrometric determination of COD by microwave atmospheric digestion, the result could be gained accurately.
所以采用常压微波消解分光光度法测定水样COD值减少消解反应时间，仍然可以获得准确的结果。

The first method use less reagents and avoid the secondary pollution from silver salt and mercuric salt and chromium salt with short digestiontime which reduce the energy.
试验过程试剂用量小，减少了银盐、汞盐、铬盐带来的二次污染问题；消解过程短，能有效降低能耗。

After 48 hours, the cells began to adhere. The results demonstrated that the improved method shortens digestiontime, and easy to obtain a great amount of purified chondrocytes.
