Objective: In this paper, the antioxidant of the bulbil saponin on DPPH, hydroxyl radicals, superoxide radicals was studied.
目的:研究零余子皂甙对DPPH、羟自由基、超氧自由基清除作用以及零余子皂甙的TEAC值。
Subgroups with finite index of a Hecke group, which are called congruence subgroup, are often used in researching Dirichlet series, so it is necessary to investigate their structure.
Hecke群的有限指数的子群(称这些子群为Hecke群的同余子群)同样在研究Dirichlet级数发挥了重要作用,调查这些子群的结构是非常必要的。
