吸热的

In two mechanisms, the barriers of the epoxidation step are very small, the overall reaction is endothermic or nearly thermoneutral.

两种机理中环氧化步的能垒都很低，整个反应是微弱吸热或热中性的。

In the temperature range of 30—680℃, the thermal decomposition process was composed of four major stages. The first stage was an endothermic process with the loss of four coordination water molecules.

在30~680°C温度范围内，[Cu2(H2O)4]2的热分解过程分为四个阶段，其中，第一阶段为脱去四个配位水分子的过程，表现为吸热过程。

Therefore, the former solar air heater was proved to be able toabsorb more radiant heat energy from the sun to increase the heat convection between the absorber flat plate and the air.

该集热器可增加对太阳辐射热能的吸收，加强吸热体和空气的对流换热。

We can see from the Rankine cycle: the beginning of a moderate early increase of steam pressure (that is, raising the average temperature of the endothermic process), or reduce the exhaust steam temperature is to improve the thermal efficiency of effective measures.

由郎肯循环可知：提高蒸汽初温和初压（即提高了吸热过程的平均温度）或降低乏汽温度，是提高热效率的有效措施。

The results show that the metal stannate combined with Mg2 can be used as a highly effective flame retardant for flexible PVC, and it can be seen that the Mg2 enhances the flame retardant properties of the samples through the endothermic dehydration, the stannate may act in both the condensed and vapor phases, but mainly in the condensed phase as a Lewis acid.

结果表明：锡酸盐和Mg2复合使用能明显提高对软PVC的阻燃效率，Mg2主要通过脱水吸热作用使材料的阻燃性能提高，而锡酸盐可分别在凝聚相和气和起作用，但主要为凝聚相Lewis酸催化机理。

At present, solar vacuum tube The ratio of heat in 93.5%, while other solar water heating systems in the thermal efficiency is about 50 percent.

目前，太阳能真空管的吸热比率在93.5％，而其他太阳能热水系统的热效率却在50％左右。

The thermal decomposition of the copper acetate dihydrate in a static air atmosphere was investigated by TG-DTG techniques.

用 TG-DTG 和DSC研究了TNPG·2/3H2O的热分解过程，在10℃·min-1的升温条件下，其熔点为167℃，有两个吸热阶段，有两次质量损失过程，在熔化时剧烈放热分解。

Effect of Ni loading, prereduction and reaction temperature were studied.

甲烷二氧化碳重整制合成气近年来引起学术界和产业界的广泛关注，但该反应是强吸热反应，能耗大并且催化剂易于积炭，因此限制了该工艺过程的工业应用[2，3]。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
