Abstract : thermal ignition of black powder and single base powder by an electrically heated wire was experimentally studied . critical igniti on current through the wire and time - to - ignition was measured . temperatures of the wire when ignition of powders occurred were calculated 文摘:用实验方法研究了黑火药和单基发射药在电热丝作用下的点火问题，测出了实验条件下两种药剂的临界点火电流及点火延滞期，并推算出了点火的电热丝温度。
