The size effect curve for non-ideal behavior is the relationship between the detonation velocity and the inverse radius of the cylindrical charge. In this paper we discuss the size effect curves obtained by a steel tube test for an ammonium nitrate (AN)-based explosive. The results for AN and mixtures of AN and activated carbon (AC) are examined. The composition of AN/AC and the charge diameter are varied from 0.1 to 20wt% and from 5.7 to 65.9mm, respectively, and their effect on the detonation velocity is investigated using curved-front theory. The size effect curve for pure AN has a point of inflection, and the curve can be expressed as two straight lines. Finally, the size effect curves for AN/AC mixtures are constructed and formulated for almost the entire experimental region.
寸法効果曲線は爆轟速度と薬径の逆数の関係で表せる。 この論文で，我々は硝安系爆薬の鋼管内爆轟試験によって得られた寸法効果曲線について議論した。 硝安ならびに硝安／活性炭混合物の結果が調査された。 活性炭の混合比は0.1〜20wt％，鋼管の内径は5.7〜65.9mmの範囲で変化させ，その爆轟速度への影響を検討した。 純粋な硝安の寸法効果曲線は変曲点を持ち２つの直線で表現できることが判明した。さらに，硝安／活性炭混合物の寸法効果曲線を定式化した。
