查询词典 under pressure

Under pressure from government officials in the village, a dairy farmer tried to shush his angry wife and shouted out,"I believe the Communist Party, and under the excellent leadership of the Communist Party I have a right to refuse your interview."

Due to the ability of the bivalent magnesium cation to form stable chelate complexes with carbonyl compounds,magnesium methylate for example is used as a selective carbonyl condensing agent. Three synthesis routes was proposed based on literatures and comprehensive comparison with other ways. First,Magnesium methylate is prepared by reacting magnesium metal with dry methanol.The magnesium salts of"higher"primary alcohols,i.e.alcohols with ≥ 2 carbon atoms,do not react directly with pure alcohols under normal conditions.In fact catalysts are required to set the reaction in motion and the preparation is performed under pressure at the higher temperatures.

一、直接合成法：本文将镁与无水甲醇直接反应制得甲醇镁；"更高级"的醇（比如C≥ 2的醇）在无催化剂的条件下无法直接和镁进行反应，本文以CCl4为催化剂将无水乙醇与镁直接反应制得乙醇镁，但是以原甲酸三乙酯为催化剂无水乙醇与镁无法反应；不论是以CCl4为催化剂还是以原甲酸三乙酯为催化剂，丙醇均无法与镁直接反应。

The result of stress analysis shows that temperature load induced remarkable thermal stress, and under pressure and temperature load, the distribution of the stress depend on the thermal stress. The most dangerous casse is not the steady operating case, but the transient case at the moment that the shell-side fluid is just shut down, but tube side pressure load and thermal load still retain.

通过强度分析表明，温度载荷对管板造成了较大的热应力，而且在温度载荷及压力载荷共同作用的工况，热应力决定了整个管板系统的应力分布；本题研究的管板的危险工况不是发生在管程载荷、壳程载荷和温度载荷同时作用的正常操作工况下，而是发生在可能出现的壳程压力先停(管程载荷和温度载荷同时作用)的瞬态工况下。

These parts are vulcanized under pressure to form a pressure-containing sleeve that is the heart of a Pinch Valve.

这些部件是在压力下硫化并形成压力套管，这是夹管阀的心脏部分。
