吸热的

"If it is positive, the reaction is endothermic; if it is negative, the reaction is exothermic."

如果这个热量是正的，就说这个反应是吸热的；如果反应热是负的，那就是放热反应。

Mainly in aspination Geld derivation of non-polar molecule mixed absorbheat noheat or at the time of the system, and for a strong system of polar molecules, fierce an hydrogen bond formation, mixing, when heat release, the results do not apply to deduce the packaging business card printing and membership card making ink.

主要是在吸取赫尔德推导的非极性分子混合时无热或吸热的体系，而对于强极性分子构成的体系，凶为台氢键形成，混合时会放热，则该推导结果就不适用包装制卡和会员卡制作油墨方面。

The adsorption isotherm of neptunium on silica gel correspond to the form of Langmuir isotherm. According to Clausius-Claperon equation,from the slope in InKd vs 1/T plot,adsorption heat could be estimated. From the data of adsorption heat it is concluded that the adsorption of neptunium on silica gel in nitric acid solutions belongs to chemical adsorption and the adsorption process is an endothermic reaction.

三种价态的镎在硅胶上吸附的等温线符合兰格缪尔吸附等温线的形式，是单分子层吸附；根据克劳修斯-克拉柏龙方程，以1nKd对1／T作图，通过直线斜率计算出吸附热，从吸附热的数据可判断三种价态的镎在硅胶上的吸附属于化学吸附，是吸热的过程；对NpOV）、Np和Np（VD在硅胶上的吸附进行了比较，提出了三种价态的锋在硅胶上吸附的机理。

The Kalina cycle which uses ammonia-water mixture as the working-medium, has the characteristics of lower vaporization temperature and non-isothermal heat absorption. Therefore, the Kalina cycle is used in low temperature waste heat recovery based on introduction of operating principle. The primary parameters of Kalina and Rankine cycle are optimized by mean of genetic algorithm respectively, and the net output power of the two cycles is compared on the same condition.

卡林纳循环采用氨水混合物作为工质，具有气化温度低和非等温吸热的特点，因此，在简要介绍其工作原理的基础上将其应用于中低温余热回收，采用遗传算法对卡林纳循环和常规朗肯循环的主要参数进行了优化，在相同的余热条件下，比较了卡林纳循环和常规朗肯循环的净输出功率。

Relation of two equivalent entropy drop method is conducted, and doing work efficiency of reheater has different choices.

证明了两种等效热降法的重要关系，指出再热器吸热的作功效率有不同的选择方法。

Besides these, the present calculations indicate that the epoxidation of ethylene is slightly endothermic or exothermic in sextet and quartet states, respectively.

另外，我们的计算结果显示乙烯环氧化反应在六重态下是微弱吸热的，而在四重态下是微弱放热的。

Or heat-pipe evacuated collector tubes with a flat absorber and a semicylindric absorber , relative solar irradiance changing with incident angles on various points of absorber s have been measured respectively by using a solar simulator.

以太阳模拟器为光源，对平面吸热板和半圆柱吸热板热管式真空集热管测定了玻璃罩管内吸热板表面各点随光线入射角变化的相对太阳辐照强度分布，给出了平面与半圆柱吸热板平均相对太阳辐照强度随人射角变化的规律及三维拟合公式，并对两种情况的实验结果进行了初步分析。

A detailed analysis of the experimental results implied that the attractive forces play a main role in the collisional quenching processes of NCO by the quenchers studied in this work, and for some quenchers, the quenching of NCO is probably controlled by the entrance-channel and might be ascribed to the contribution of chemical reactions.

这一加成过程是一个入口势能面属于纯吸引型的无垒过程，故是NCO+O反应的主要通道。二是O原子攻击NCO分子的O原子得到中间物tran-NCOO，再通过C-O键的断裂生成产物CN+OO。该产物通道由于是吸热的，故很难发生。

Similarly, with Baked Alaska, hard ice cream is placed on a sponge cake, which is on a non-heat-absorbing plank.

与此相似地，&火焰雪山&冰淇淋的做法是，把冰冻好的冰淇淋放在一块坚实的蛋糕上，蛋糕放在一块不吸热的隔板上。

Similarly, with Baked Alaska, hard ice cream is placed on a sponge cake, which is on a non-heat-absorbing plank.

与此类似地，&火焰雪山&冰淇淋的做法是，把冰冻好的冰淇淋放在一块松软的蛋糕上，蛋糕放在一块不吸热的隔板上。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
