A new powdery ammonium nitrate fuel oil explosive was produced to solve the problems of complicated production process and low explosion energy. The explosive was made of ozocerite,surfactant,gelatinizer and water, which were made into slurry mixed solution at 105-110 ℃, and was dehydrated from -0.07 MPa to -0.09 MPa.

为解决当前粉状铵油炸药生产工艺复杂，爆炸能量低的难题，在105～110 ℃将硝酸铵与地蜡、表面活性剂、吸附剂和水混溶制成浆状混合液，并在真空度为-0.07～-0.09 MPa压力下脱水干燥，研磨过筛，得到粉状铵油炸药。

The use of porous prolled ANFO explosives prill in the experiment of open chamber blasting helps to solve a series of problems in the process of using ammonium nitrate fuel such as its liability to stick to the hole wall and the difficulty in loading explosive power etc.

Ignition and combustion processes are discussed in this paper and flame retarding methods can be derived from these discussion results.

在研究中，根据由不同炸药的分子结构和热分解特点决定的不同的阻燃机理选择适当阻燃剂来实现阻燃炸药的阻燃。

It's understood the explosives were planted in his luggage by Slovakian authorities testing security procedures at Bratislava Airport.

据称，这些炸药是斯洛伐克官员在斯洛伐克机场进行安全检查时将炸药放在他的行李内的。

If the wetting capability of polymer solution on the surface of solid explosive is good,its adsorption amount is much.

若聚合物溶液在固体炸药表面湿润性好，则其在炸药表面上的吸附量大。

If the wetting capability of polymer solution at the surface of solid explosive is good, its adsorbed amount is much.

若聚合物溶液在固体炸药表面浸润性好，则其在炸药表面上的吸附量大。

With the theoretical model of spherical grain dynamics of sparse two-phase flow in single dimension, computing formulas of velocity′s attenuation and scattering distance were built for explosive residue grains in horizontal. Then, a simplified theoretical model on distribution of explosive residue was put forward on the basis of a spherical space with radius equalling to maximum horizontal scattering distance of explosive residue grains with certain diameter.

为了对残留物颗粒的飞散运动及分布规律进行理论分析，利用球形颗粒一维稀疏二相流动力学模型，研究得到炸药残留物颗粒的速度衰减及水平飞散距离计算公式；在此基础上，建立了以某粒径残留物颗粒水平运动极限距离为半径的炸药残留物颗粒球面空间分布简化理论模型。

Codenamed 'Divine Strake', the test will not involve a conventional bomb as such, but will detonate a vast pile (amounting to 700 tonnes) of ammonium nitrate and fuel oil with 136 kg of C-4 explosive - the US equivalent of Semtex - as the initiator.

代号名称"神圣列板"，测试将不包括一种传统的炸弹，但是将会引爆一个的巨大反应堆（共计700吨）：硝酸铵和燃料油连同136公斤C4炸药-塞姆汀塑胶炸药的美国同等物-被当做起爆药。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
