Evaluation and comparison in the results of surgical treatment of lumbar spondylolisthesis with reduction or non-reduction of spinal sliding 腰椎滑脱症手术复位与未复位的对比
By relative non-reduction attribute and frequency of attribute, a attribute reduction algorithm, simply, operating easily, was given. Meanwhile, the author also gives a sample to proving the availability of algorithms. Bi-core(A)的几种方法,借助相对不可约属性和属性频率得到属性约简的算法,该算法简单易实现,速度快。
The new methods for isotopic measurements of boron, chlorine and bromine by thermal ionization mass spectrometry using the non-reduction characteristics of thermal ion emission have been summarized and the important evolution in isotopic measurements of boron, chlorine and bromine has been achieved in this study. 该项研究成果总结了利用石墨的非还原热离子发射特性所建立的高精度热电高质谱测定硼氯溴同位素的方法,实现了硼氯溴同位素测定的重要突破。
It shows that the catalyst activity and selectivity for hydrocarbons to producing hydrogen through partially oxidizing and reforming method are different from that of the reduction and non-reduction catalysts. 实验结果表明,催化剂的活性组分价态不同,对烃类部分氧化重整制氢反应催化活性、生成氢的选择性影响不同,还原态的好于非还原态的双金属催化剂;
THE INVESTIGATION ON NON-REDUCTION CHARACTERISTICS OF THERMAL ION EMISSION OF GRAPHITE& A comparison for characteristics of thermal ion emission of different graphite 石墨非还原热离子发射特性研究&不同石墨热离子发射特性的比较
And look at the effects from two aspects: the behavior of the state-owned holders and actions of the small non-reduction holders. 并分别从国有大非减持和小非减持两个方面来看待减持行为给股权结构造成的影响。
