Heat release is a measure of the contribution that a burning material makes to a fire in progress, for example, a high rate of heat release will produce a high rate of rise of temperature in surrounding unburnt material and accelerate fire spread.

放热是易燃材料在燃烧过程中所起作用的衡量尺度。打个比方，高速率的放热将对不完全燃烧的材料产生了高速率的升温并且加速了火焰的蔓延。

The experimental results indicated that under the steady operating conditions, the ignition timing of the base fuel (PRF90-90% iso-octane+10% n- heptane), which is equivalent to RON 90, delayed and the peak value of the heat release rate was low compared to the base fuel with single additive (Ditert-butyl peroxide-DTBP, Dicumyl peroxide-DCP, Tert-butyl hydroperoxide-TBHP, Tert-butyl cumyl peroxide -TBCP or Cumene hydroperoxide-CPO) which advanced ignition timing and increased the peak of the heat release rate obviously.

试验结果分析表明，在HCCI发动机燃烧稳定工况下，没有添加剂的基础燃料记作PRF90(为90%异辛烷与10%正庚烷的混合，相当于90号汽油)着火滞后，燃烧放热率峰值低，而混有单一添加剂(Ditert-butyl peroxide-DTBP、Dicumyl peroxide-DCP、Tert-butyl hydroperoxide-TBHP、Tert-butyl cumyl peroxide-TBCP或Cumene hydroperoxide-CPO)的基础燃料则着火明显提前，燃烧放热峰值升高。

It can be seen from their DTA curves that the addition of rare earth oxides could make the first exothermal peak of ammonium perchlorate hysteresised and the second exothermal peak advanced.

结果表明：所有稀土氧化物均能使高氯酸铵的第一放热峰滞后，而第二放热分解峰提前；随着稀土添加量的增加，两分解峰逐渐靠近，最终合并为一个分解放热峰，分解热也大大提高。

The drug release experiments in vitro indicated that with the increase of PLA molecular weight, the drug release rates decreased. 4ac releasing from 4ac-PLA-NP could be characterized by Weibull's equation. The interaction between 4ac and others compositions was not detected by DSC. The peak position of 4ac in DSC did not changed comparing 4ac with 4ac-PLA-NP lyophilize injection. Thc X-ray result showed that the peak of 4ac-PLA-NP was piled up between 4ac and other compositions.

差示扫描量热分析结果表明药物与各组分之间无明显的相互作用，制成4ac-PLA-NP冻干针剂后，其放热峰主要表现为聚乳酸的放热峰：X-射线衍射结果表明药物与载体间无相互作用，4ac-PLA-NP主要表现为4ac与载体之间的叠加峰；TLC、FT-IR也同样表明药物与载体无相互作用，它们之间是一种物理结合，并未有新物质生成。

In order to simulate phenomenologically the process of transformation from fuel injection rate to heat release rate, a quasi-dimensional combustion model has been established, which includes fuel-air mixing, droplet evaporation, ignition delay, heat release and heat transfer.

在只有喷油规律的条件下，本文建立了分韦柏放热规律模型，通过对喷油规律依次分段，各分量按各自韦柏规律燃烧，实现了从喷油规律对放热规律的直接快速预测。

The exothemicity of impregnated catalyst is not only little in air, but exothemicity is little and heat is dispersed during sulfurization. H2S concentration is much higher in effluent gas, if the effluent gas could be recycled, then sulfiding degree of catalyst is increased and resource is saved.

浸渍催化剂不仅在空气中保管时放热温升小，而且硫化时放热少且分散；尾气中H_2S浓度较大，如果能循环利用尾气，那么既能提高催化剂的硫化度又能节省能源。

DO6O of XRD analysis and skeletal vibration of IR spectrum reveals that nickel ions were located at the centers of octahedra.

CLS在1000℃左右层结构瓦解，出现一个放热峰，而NiSMM上不存在这一放热峰，表明NiSMM的层结构到1000℃时也未被破坏。

WF exothermic welding is Weaflida's patent product in China, which has the best quality in China as the same product in U.S and U.K. So WF Exothermic welding powder is qualified by national authority test department.

WF放热焊接是Weaflida在中国的专利产品，其放热焊粉也通过了国家权威部门的检测，因此在中国市场上它是同类产品中质量最好的，并达到了美国，英国在此产品中的生产标准。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
