hdo

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。

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（HierarchicalDesignOptimization，简称HDO）技术。

HDO divides the integrated optimization of composite wing structures into two sub-problems that are easy to be solved : upper level optimization and lower level optimization .

它将复合材料翼面结构综合优化设计问题分解成两个易于求解的子问题：顶层优化设计和底层优化设计。

The effects of the temperature and pressure on the mole fraction of HDO in the top segement of the column have been examined for the hydrophobic catalyst .

研究了温度、压力对疏水催化剂氢同位素交换时交换柱上部排出的HDO摩尔量的影响。

It is very necessary to selectively remove oxygen from the bio-oil via the hydrodeoxygenation ( HDO ) to improve the quality of the upgraded bio-oil .

必须对生物油进行加氢脱氧精制来提高油品的品质。
