NettetHock cleavage also adequately explains the many discrepancies discovered in the currently accepted scission mechanism which involves peroxyl radical cyclisation. From … Nettet由于这两个反应是通过磷酸单酯和羟基缩合生成3′-5′磷酸二酯，故称为磷酸二酯（合成）法。 在磷酸二酯法中，由于产物为磷酸二酯，磷酸上所剩下的OH基团，虽然化学活性较小，但也能发生反应，因此，当合成的寡核苷酸链逐渐增长时，由这个磷酸OH基团所带来的副反应也愈益严重，使合成产率急剧下降。 目前这个方法已基本上被淘汰，改进的办 …

Nettet基本套路是搭模型——随机动力学——热力学——熵产生的各种分解——一顿解释后再做系统最优化。 理论方面，除了元老Onsager、Prigogine和Lebowitz，有些小学派，像涨落定理派（Jarzynski、Crooks、Evans）；随机热力学派（Seifert）；以及给热力学一个统一数学框架的“Large Deviation”派 (Gaspard、Touchette、这里还得提一下在湍流和混沌颇有 … Nettet(Scheme 3), method A quantitatively gave typical Hock cleavage products (7a and 7b in ca. 40%).
