放热的

For the water-content explosives, the heat is released after the water is vapored during the heating.

对于含水炸药，受热过程中首先发生的是破乳、脱水，脱水之后才开始迅速分解放出热量，二级煤矿许用乳化炸药活化能随着分解率的增加而增大；平均活化能为E=124.05kJ/mol，从开始放热到热爆炸临界点的延滞期为

The second exotherm could be ascribed to the relatively compactconformation of individual polystyrene chains; upon heating during DSC scan, phenylring could stack to form some kind of ordered regions inside micro-PS.

而广角X射线衍射以及in situ FTIR等研究证明第二个放热峰则归因于micro-PS特殊的链构象：DSC升温过程中链的疏松构象易于通过苯环的堆积形成局部链段有序化，从而放出热量(大约6.4 J／g)。

Three-dimensional numerical simulation of the combustion process in an alcohol engine, with a new type of spark-ignited direct-injection circularly stratified-charge combustion system, is carried Out. The computed pressure and heat release data coincide with the experimental results well.

It has been reported that chairs without armrests show lower peak heat release rate and slower fire development rates.

被报道没有扶手的椅子显示更低的高峰放热率和更加缓慢的火发展率。

The heat-producing power of weapon-grade plutonium, weapon-grade uranium and depleted uranium per kilogram were calculated through simulation and dynamic decay cascade, the regression line was fitted and analyzed. The temperature fields of the nuclear explosive device raised by Steve Fetter were analyzed according to the simulation results of the heat-producing power of the exothermic materials. The hypothetical models of the nuclear explosive device were modified according to the normal disposal method in industry manufacture, and thermal stress distribution was simulated with the information processed before.

通过级联衰变动力学计算得到每千克武器级钚、武器级铀及贫化铀的放热功率，并对仿真结果进行拟合分析；选取其最大值对Steve Fetter提出的公开核装置假想模型进行温度场数值仿真；根据工业生产实际对Steve Fetter提出的公开核爆炸装置假想模型进行修订，并对其进行热应力仿真分析。

As a new type of synthesis process of materials, self-propagating high-temperature synthesis rose at the end of 1960 s to get compounds in a short time by means of the combustion heat generated by reaction itself.

中文摘要：自蔓延高温合成是二十世纪六十年代末兴起的材料合成新技术，其显著特点是利用化学反应自身放热瞬间完成其它方法无法实现的材料的合成。

According to the test data, the charging time is reduced by 10%40%, and the discharging time is reduced by 10%-15% when the encapsulated stearic acid, sliced paraffin and lauric acid are used and arranged in the storage bed.
