作為一種敘事散文,回憶錄的寫法理應不拘一格,但事實上大多數作者都是採取的無技巧筆法,也就是一個接一個地敘述事件直至結束,其間加入自己對歷史的感受和思考。這種寫法的缺陷是事件與事件之間沒有緊密的聯系,只是按照時間順序先後出現,使作品結構顯得鬆散,難于形成整體效應對事件平鋪直敘,敘事節奏缺乏變化,靜態描述有餘而動感不足,再現出的是一幅幅靜止的歷史畫面而非一幕幕環環相扣的歷史活劇以事件為中心,以人紀史,疏離了文學揭示人生問題的宗旨。Changes of nerve growth factor protein and mrna in the vulva skin of rabbits after ultrasound irradiation
