KEY WORDS non-convex objective function;inexact line search;perry and shanno's memoryless quasi- newton methoa;convergence (上接第500页) Detonation Velocity Characteristics of Emulsion Explosives Sensitized by Glass Micro-balloons SONG Jinquan2,WANG Xuguang 2,YU Yalun,CUI Anna 1)Resource Engineering School,UST Beijing,Beijing 100083,China 2)Beijing General Research Institute of Mining and Metallurgy,Beijing 100044,China ABSTRACT By means of the laboratory manufacture technology established by UST Beijing,emulsion ex- plosives(EE)test samples sensitized by glass micro-balloons(GMB)were manufacture.Influence of GMB content and density of EE on the detonation velocity are studied.The detonation velocity characteristics of the industrial explosives are analysed.With the increase of the deusity of EE,the detoration velocity first in- creases to the top point,then decreases,untill the emulsion explosiues have been dead pressed. KEYWORDS Detonation velocity Emulsion explosives Glass micro-balloons。 北 京 科 技 大 学 学 报 年 第 期 ， 一 研沈 幻以 尤醒 月万封 ，， 月 脚召 械雌卿 ， ， ， ， 几。 印山由口印仁 匕 廿 ， 吨 ， ， 一 节沈 了 叮 ， ，八 一 卫 烧 节沈 一 了 ， 够 上 接第 页 一 口 孔 环月刀 筋岁 ’孔 ‘， ， 叨 力 ， ， ， 名， ， 奴江 ， 攻旧 仍 叭 勿 一 江 ， ， 小 ， 丫 一
