Problems solved by technology

[0003] However, there are still some problems in the prior art: (1) the comprehensive evaluation of the detonation performance of explosives needs to measure the detonation heat, detonation velocity, detonation pressure and detonation temperature respectively, the test period is long and the cost is high; (2) the existing explosives The detonation performance parameter test method requires a relatively large amount of test charge. The amount of detonation heat test charge for each explosive is at least 25g, the amount of charge for detonation velocity is about 100g, and the amount of charge for detonation pressure is about 50g. The measurement of explosion temperature A standard method has not yet been formed, and at least 200g of charge is required to fully measure the detonation performance of explosives; (3) The specifications of the samples required for the measurement of multiple parameters are different, the sample preparation is complicated, and the quality consistency of each sample is difficult. ensure
