Multiparameter liquid propellant component simulation standard substance

Belonging to the field of testing technologies, the invention designs the absorbance value of a reference substrate and a standard substrate to simulate the content of acetylene in liquid oxygen, nitric oxide, iron ions and chlorine ions in green dinitrogen tetroxide, and iron ions and chlorine ions in anhydrous hydrazine. The invention relates to a multiparameter liquid propellant component simulation standard substance, which is composed of one reference substrate and 10-15 pieces of standard substrates. Both the reference substrate and the standard substrates are optical glass sheets, the absorbance value at the 540nm of the is in the range of 0.1-0.85, the absorbance difference between the 510nm of not less than 5 standard substrates and the reference substrate is in the range of 0-0.13, the absorbance difference between the 510nm of not less than 2 standard substrates and the reference substrate is in the range of 0.13-0.49, and the absorbance difference between the 460nm of not less than 2 standard substrates and the reference substrate is in the range of 0-0.15, and the absorbance difference between the 460nm of not less than 2 standard substrates and the reference substrate is in the range of 0.15-0.32. The standard substance has stable and accurate value, is convenient to use, eliminates the value deviation of a standard solution, effectively reduces the test cost, and saves the test time by more than 5 times.
