查询词典 absorption coefficient

The results of absorption spectra of chloroplasts showed that NO alleviated the effects of Cd on absorption spectra of chloroplast by raising the relative absorbance at 436 nm,480 nm and 470 nm,which caused lower contents of carotinoid and chlorophyll.

结果发现，Cd对叶绿素a、叶绿素b和类胡萝卜素含量都有不同程度的降低，NO处理缓解了Cd的影响，使叶绿体室温吸收光谱的吸收率提高；Cd导致686 nm处峰偏移4 nm，峰值降低33%，734 nm处峰值降低23%，外源NO缓解了Cd对光合系统的影响，使得叶绿体低温荧光光谱在686和734 nm的峰值分别仅下降17%和10%；以DCPIP为人工电子受体， Cd处理的叶绿体中DCPIP还原速率较慢，光合电子传递(H2O→DCPIP)速率降低1.5倍，外源NO处理显著缓解了Cd对电子传递链的抑制，使其光合电子传递速率恢复到对照的水平。

The wastewater from gum benzion production contains benzaldehyde, cyanide, gum benzoin and ethyl benzoate. When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low. Thus the absorption liquid produces a great deal of foam and feculence.
