查询词典 intermediate differential

A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.

一、发现了2-位氧化α-甲基D-葡萄糖苷的芳胺亲核加成引起羰基转位的新方法，利用核磁共振氢谱及碳谱对邻苯二胺与2-位氧化α-甲基D-葡萄糖苷加成生成的稳定中间体半缩酮化合物在氘代丙酮中的变化进行跟踪，结合对转化产物的氢氢相关谱和HMQC结构确证，提出了该反应中2-位羰基通过烯醇化互变而转至3-位的机理并得到了验证。

Applying integral intermediate value theorem, new effective elasticity modulus expressions were presented, which creep aging coefficient can be calculated by the creep coefficient of intermediate time of incremental time segment. Creep and shrinkage strain were treated as a kind of compulsive strain. Compulsive strain methods were used for the analysis of creep effect and shrinkage effect about concrete curved box-girder bridge.

For example, when intermediate calculations become larger than can be represented by a floating-point or an integer variable the intermediate result will be invalid.

例如，当中间的计算变得大过可以被floationg-point或整数变量所能代表时，中间结果将是无效的。

First, considering the factor of unit gain space and the space limit, the common expression s of multiple views were selected out as the intermediate result, and the algorithm which was used to define the intermediate set was put forward. Then the algorithm of maintaining multiple views with this set was given. At last, the correctness and efficiency were given after the analysis and experiments.
