查询词典 weak solution

On the basis of the analytical results of infrared spectrometry,paper chromatography,tyrosine color development reaction and the assay of anti-acid buffer capability,we confirm that chlorine dioxide in stabilized solution with sodium percarbonate as stabilizer exists in the form of chlorition (ClO2-) and exists in NaHCO3-Na2CO3 buffer system. When the stabilizer is sodium perborate,chlorine dioxide may be retained in the solution comprised of H3BO3-Na2B4O7 as a labile complex.

The rat hearts were harvested and mounted on the Langendoff apparatus to perfuse with K-H buffer solution to estimate the leakage of enzymes of the myocardial tissue. Then they were arrested and stored in each preservation solution (4℃) for 8 hours. At the end of the storage period, the rat hearts were resumed and reperfused in Langendoff model. The water content and the leakage of enzymes of the myocardial tissue were measured.
