The results indicated that a dependable kinetic model could be obtained by modifying the Temkin equation by considering the H2 and NH3 adsorption factors. Activation energy for the ammonia synthesis reaction was obtained as 90.2 kJmol^(-1) after linear fitting the kinetic and thermodynamic parameters k, K(subscript H2) and K(subscript NH3) with the Arrhenius and Van't Hoff equation, which was much lower than that over iron-based catalyst, which indicated that the activation energy barrier of N2 dissociative adsorption on Ru was far lower than that on either the conventional magnetite-based catalyst or wustite-based catalyst; the hydrogen adsorption heat was 76.2 kJ mol^(-1), indicating that the adsorption of hydrogen on the Ba-Ru-K/AC catalyst was so strong that it inhibitied the dissociative adsorption of nitrogen.

结果表明，在Temkin方程中加入H2和NH3的吸附项能够获得可靠的动力学模型，用Arrhenius和Van't Hoff方程对动力学和热力学参数k、K(下标 H2)和K(下标 NH3)进行线性拟合，得到氨合成反应的活化能为90.2 kJmol^(-1)，远低于铁基催化剂，说明Ru上N2的解离吸附活化能垒远低于传统磁铁矿基催化剂和维氏体基催化剂。H2的吸附热为76.2 kJmol^(-1)，证明Ba-Ru-K/AC催化剂上H2的吸附较强烈，对N2的吸附有强烈的抑制作用。

Here we report a 22year-old man who suffered from recurrent fever accompanied by chest and abdominal pain for more than 10 years. The attack frequency was about once per 23 weeks. Although he consulted many clinics and even received appendectomy at the age of 15, no definite diagnosis was given. During the admission, many laboratory examinations failed to show any abnormality except mild leukocytosis and elevated C-reaction protein. Image studies including chest X ray and abdominal CT scan showed negative result but, interestingly, Gallium-67 scan showed a hot spot in right lower chest and right lower abdomen. After prophylaxis with colchicines 1.0 mg per day, he has enjoyed more than 2 years without the above symptoms.
