查询词典 trinitration

To assess the thermal contribution from oxidation reaction, the standard formation enthalpes of all reactants and products were used to calculate the oxidation enthalpies. It could be found that all oxidation reactions were exothermic. And oxidation played a more important role during the toluene trinitration at high temperature, because the reaction temperature of toluene trinitration is the higher than mononitration and dinitration, and the temperature coefficient of oxidation is higher than that of trinitration too.

为了考察不同阶段氧化副反应对反应放热的贡献，用反应物和产物的标准生成焓推得氧化反应的理论反应热，计算结果表明，各段硝化的氧化副反应均为放热反应，其中三段硝化反应由于反应温度最高，氧化反应的温度系数比硝化反应高，故氧化副反应对三段硝化影响最大。

Studies on the trinitration of toluene showed that, the trinitration temperatures were high enough to intensify oxidation, and the two thermal hazard evaluation methods mentioned above couldn\'t evaluate the situation well. Results were found from the reaction calorimeter experiments that lower reaction temperature and decelerating dosing rate could prevent thermal accumulation and decrease thermal hazard efficiently.

在对三段硝化反应进行热危险性评估时发现，三段硝化反应的温度很高，氧化副反应随温度升高而加剧，风险矩阵法和失控情景分析方法难以准确评估该情况下的热失控危险，但实验结果表明降低反应温度，减缓加料速率能有效地防止热积累，减小反应过程中的热危险性。

Mononitration, dinitration and trinitration of toluene are very important reactions. Products of these reactions are widely used in medicine, dyestuff, explosive, pesticide, etc.

甲苯的多段硝化是重要的化学反应过程，其各段硝化产物在医药、染料、炸药、农药等方面应用广泛。

Pachomius manual labour was organized as an essential part of the monastic life; and since it is a principle of the monks as distinguished from the mendicants, that the body shall be self-supporting, external work of one sort or another has been an inevitable part of the life ever since.

根据圣pachomius体力劳动组织作为一个重要组成部分寺院生活；以来，这是一个原则的和尚，作为有别于乞丐，该机构应自支撑，对外工作的这种或那种已一个必然的一部分，生活至今。

In order to study the effects of parametrical rolling on the ship movement and tilts, in allusion to ship's navigating in regular following waves, the equation of ship rolling motion is transformed into normal Mathieu equation by proper variable replacement when strong parametrical excitation in restoring moment varied according to sine or cosine wave.

为研究参数横摇对船舶运动和倾覆的影响，通过对船在规则波上随浪航行时，恢复力矩中出现的1个以正余弦规律变化的强参数激励项进行适当的变量置换，将船舶的横摇运动方程转换成标准形式的Mathieu方程。
