摘要:
An apparatus for purifying the nitric oxide in the exhaust gas of the diesel engine has a NOx adsorber converter mounted on an exhaust gas pipe close to the engine, a urea catalyst converter mounted on the exhaust gas pipe at some distance from the NOx adsorber converter, and a urea supplying means connected between the NOx adsorber converter and the urea catalyst converter.
摘要:
A method of forming an epitaxial silicon structure is disclosed. The method includes performing a first epitaxial growth process using a first source gas including silicon (Si) and hydrogen chloride (HCl) to form a first epitaxial silicon layer on a substrate, and performing a second epitaxial growth process using a second source gas including silicon (Si) and chlorine (Cl) to form a second epitaxial silicon layer on the first epitaxial silicon layer.
