Proper distance can help the reader develop psychological reflection during the reading process, then the reader can judge the work objectively and gets great pleasure from reading, and thus, the aesthetic effect is achieved. In The Adventures of Huckleberry Finn, Mark Twain controls the distance between Huck, the narrator and the reader; the distance between Huck, the unreliable narrator and Huck, the character successfully, which result in strong artistic effect.展开更多

Ammonia is widely produced and transported globally, and stores hydrogen in its bonds making it an excellent fuel for fuel cells. The high temperature of SOFCs allows for internal decomposition of ammonia. Previous models of ammonia-fed SOFCs treat ammonia decomposition as having first order dependence on ammonia partial pressure, and ignore the effect of hydrogen inhibition. However, research has shown that at low temperatures （≤ 600 ℃） and low ammonia partial pressures, the rate of ammonia decomposition is inhibited by the presence of hydrogen. This hydrogen inhibition effect was studied and implemented in a model of an ammonia decomposition reactor. Results showed that it may significantly decrease the rate of hydrogen generation. This work sets the foundation for more accurate modelling of intermediate temperature ammonia-fed SOFCs.展开更多
