Chemistry of Protostellar Clumps in the High-mass, Star-forming Filamentary Infrared Dark Cloud G034. 43+ 00.24

Abstract
To search for the potential chemical dependence on physical conditions, we have carried out the study of chemistry on the nine protostellar clumps of the high-mass star-forming infrared dark cloud G034. 43+ 00.24, with observations of several∼ 1 mm lines by the Atacama Pathfinder EXperiment telescope. They include CO/13 CO/C 18 O (2− 1), HCO+/H 13 CO+(3− 2), HCN/H 13 CN (3− 2), HNC (3− 2), CS/C 34 S (5− 4), SiO (6− 5), SO (6− 5), pH 2 CO (3− 2), and CH 3 OH (5− 4). All the clumps are simply grouped into two classes: high-luminosity protostellar clumps (MM1–MM4,
