Implement with Cantera/Python. The repo includes the accepted manuscript and the demo codes, including the mechanism files.\n\n# Instruction\n\n+ If you need the relative sensitivities, you can simply use the local temeprature sensitvity. But take care of the positive/negative sign. You can figure out the sign based on intution, or compute one of the sensitvity with brute force approach.\n\n+ If you need the absolute value of the sensitvities. You can follow the paper and compute two top sensitive reactions.\n\n# API \n\nInitially, I planed to write an api, later on , I realized that it is unnessary ... But if you find that an api might be useful, you can start from the proposal bellow. \n\n+ idtSens(gas, T, P, X, Type = 'UV', factor = 0.05 )\n\n    + gas: The object of IdealGasMixture\n    + T: [K]\n    + P: [atm]\n    + X: Mixture of Fuel and Air, e.g., 'H2:1.0,O2:1.0,N2:3.76'\n    + Type: 'UV': Constant Vloume Reactor, 'HP': Constant Pressure Reactor\n    + factor: the pertubation factor for the finite difference (brute force) approach, default value is 0.05\n\nAlternatively, the reaction mechanism .xml file can be passed.
