hdo

To overcome these difficulties, in this paper ( 1) A Hierarchical Design Optimization ( HDO) technique is developed.

为了克服这些困难，本文：（1）提出了分层优化设计（Hierarchical Design Optimization，简称HDO）技术。

But WatchDog is not absolutely safe, which loses frequently the validity and makes the system paralysis.

但watchdog并非绝对安全, 常常失去有效性,使系统瘫痪.

The protecting benzyl group was removed subsequently by catalytic hydrogenation to give poly ( 5-hydroxymethyl-1,4-dioxan-2-one)( PHDON) with pendant hydroxyl groups. The polymers obtained were characterized by FTIR, 1H NMR, 13C NMR and GPC.

通过催化氢化去除苄基保护基得到聚（5-羟甲基-1,4-二氧六环-2-酮）（PHDON），并用FTIR、1H NMR、13c NMR和GPC等方法对聚合物进行了表征。

Furthermore, the key of HDO technology is developing catalysts with high activity and good stability.

而开发活性高、稳定性好的催化剂成为加氢脱氧精制技术的关键。
