Introduction
In the following paper for Explosives Engineering I discuss six of the basic,but very important,building blocks associated with the engineering of explosives.These properties include density,energy,pressure,temperature,gas product volume,and velocity of detonation.The aspects of these parameters that are reported on include their importance in the use and design of explosives,as well as their interlinking affect on each other.Also included in the paper are the descriptions and examples of theoretical calculations as well as the physical analysis of applicable property.All of this is important to know in order to efficiently utilize any explosive for the specific task given to an engineer.Through this composition of information it is my goal to broaden the understanding of these properties by my self as well as anyone else that might read the paper.Through this greater understanding of the backbone of explosives engineering,it will be easier to work with more complex topics,and with a greater comprehension of these topics.
This subject is especially important to me because of its application to future goals that I hold.While at school,my focus is to gain an understanding of the concepts surrounding explosives and energetic materials.Afterwards I want to be involved in the “invention”,synthesis,testing,and application of new energetic compounds.This class,and more specifically this paper,is the first big stride in my pursuit of a career in the field of energetic materials.
Density
Density (represented by ‘ρ’) is the mass of a compound per unit of volume,such as in g/cm3.The densities of each specific material vary greatly,but when used in explosives density can be changed in order to attain different magnitudes of thrust and brisance.For example,decreasing the density of an explosive will give a milder thrust effect and also decrease the velocity of detonation (VOD) [2].These effects are discussed more thoroughly in later sections.Some methods for altering the effective density of materials include pressing or casting,and mixing the explosive with a compound whose effect on the explosive reaction is either negligible or beneficial.Most densities used in calculations and reference tables are the Theoretical Maximum Density (TMD) of a compound.To find the TMD of a specific compound a simple linear relation can be used that will give you the answer with less than 2 - 3% error [3]:
ρ(TMD) = Ai – Ki(H)
Where H is the percent of hydrogen by weight,and Ai and Ki are constants that are dependent on the type of aliphatic compound being referenced.The groups and associated values for Ai and Ki are listed in Appendix 1.

简介
在下面关于爆破工程的文章中,我讨论了与爆破工程有关的六个最基本的、但是却非常重要预制构件特性.这些特性包括密度、能量、压力、温度、气体产生速度、爆速等参数.我们所探讨的这些参数还包括了其对爆破设计及应用的重要性,以及各参数之间的相互作用和影响.本文还对相关特性的理论计算进了阐述和举例、并对其进行了物理分析.对于一个工程师来说,如果要有效地利用各种炸药来完成某一爆破任务,那么了解上述参数特性是十分重要的.本文作者的目的是,通过所提供的信息,加深自己及他人对这些参数特性的理解.通过加深对爆破工程主要方面的理解,就可以更加轻松地应对各种更复杂的课题,并对这些课题有更全面的认识.
这一主题由于涉及我以后工作目标的应用问题,因此对于我来说特别重要.在学校时,我的重点是理解有关爆炸物和高能材料的概念,后来逐渐涉及了新型高能复合材料的“发明”、合成、试验、应用.因此本课程,特别是本论文,是我高能材料领域研究职业生涯中迈出的一大步.
密度
密度（以‘ρ’表示）表示单位体积化合物的质量,如g/cm3.不同材料的密度相差很大,在炸药应用方面,可以改变其密度以获得所需的爆破冲击力和破坏力.例如,降低炸药密度就会使炸药的冲击力降低,同时也降低了爆速(VOD) [2].这些效果将在后面的部分详细讨论.改变某种材料有效密度的方法有：压缩、压铸、或将爆炸物与另一种物质混合,前提是这种物质与炸药的反应可以忽略不计或是良性的.在计算中和参照表中采用的密度,绝大部分是某一化合物的“最大理论密度”（TMD）.要计算某一具体化合物的TMD,可采用下列简化的线形关系得出结果,其误差小于2-3% [3]：
ρ(TMD) = Ai – Ki(H)
式中H是氢的百分比数值（按重量计算）；Ai 和Ki是常数,由所参照的脂族化合物类型决定.Ai 和Ki的组合和数值见附录1.
