摘　　要：采用光电测试的方法,研究了钝感炸药的约束效应。实验结果表明,增加约束不能显著提高炸药的定态爆速,但可以使波阵面变得扁平;在装药直径相同的情况下,有约束和无约束的装药相比,有约束装药波阵面上各点法向爆速提高;约束对爆轰波波阵面的这种影响起主要作用的是约束材料的波阻抗,随着约束波阻抗的增大,这种影响更加显著。Effect of confinements on insensitive high explosive （IHE） is studied by photoelectric test. Results show that adding confinement can not enhance the steady-state detonation velocity of IHE markedly, but makes the confinement be faster than that of inconfinement mainly resulting from the wave impedance of confinement material, and the effect becomes more obvious as the wave impedance of confinement material increase.
