These indicate that ASA , as a main antioxidant , is maintained and improved by increasing DHAR activity during senescence of apple leaves to imped senescence .
说明在苹果叶片离体衰老过程中，抗氧化剂ASA代谢主要是通过提高DHAR活性来维持其高水平，抵制衰老。

Finally , the seismic imped - ance inversion is performed with the constraint of different-scale frequency component to achieve the low-frequency impedance sec - tion , the middle / high-frequeney impedance section , and the overall frequency impedance section synthesized by the former two sec - tions .
然后分别利用井的不同尺度的频率分量作为约束条件，进行了地震波阻抗反演，获得了低频波阻抗剖面、中高频波阻抗剖面以及由低频和中高频波阻抗剖面合成的全频波阻抗剖面。
