Artificially induced a single 〓elevation could effectively drive the activation, in recently ovulated oocytes (12—13 h after hCG) however, a single Ca〓 increase was futile in initiation of activation and only repetitive 〓 rises were avalable, suggesting that the activation of recently ovulated oocytes requires oscillatory Ca〓 signals as occuring at fertilization.

只有诱导卵内Ca〓多次升高才能使之激活。提示：刚排出不久的卵激活象受精一样需要胞质Ca〓波动信号。
