Since there exists some disadvantages such as poor mechanic properties and much higher burning rate pressure exponents (?1) in the fundamental formulations, this work is devoted to the improvements of combustion characteristics and mechanic properties of LOVA propellants. The effects of the crystal shape, size and contents of nitroamine particles, the types of binder, plasticizer and surface-active agents and the contents of NC on combustion performance are studied by closed bomb tests. In the mechanic properties tests, the effects of the types of binders, plasticizers and solid fillers, the interaction between binders and solid fillers and technological procedures on propellant mechanic properties are researched.

针对基础配方具有燃速压力指数远大于1、力学性能差等特点，采用密闭爆发器等试验手段，研究了诸如硝胺粒径、硝胺晶体形状、硝胺含量、粘结剂、增塑剂、硝化棉含量及表面活性剂等因素对燃烧性能的影响；采用抗沖、抗压静态试验方法，对粘结剂、增塑剂、固体填料、粘结剂与固体填料之间的相互作用及工艺条件与力学性能之间的关系进行了研究，提出了改善低易损性发射药燃烧性能和力学性能的技术途径。

包括在高温下进行的天然气热裂解，主要生产乙炔和炭黑；天然气蒸汽转化或天然气的部分氧化，可制得合成气；天然气经过氯化、硫化、硝化、氨化氧化、氧化可制得甲烷的各种衍生物；湿性天然气中的乙烷、丙烷、丁烷和天然气凝析液等，经蒸汽裂解或热裂解可生产乙烯、丙烯和丁二烯；丁烷脱氢或氧化可生产丁二烯或醋酸、甲基乙基酮、顺丁烯二酸酐等。

Ted Elsasser is a scientist at the United States Agricultural Research Service. He is studying possible signs of stress on animals. He says changed proteins called nitrated proteins may serve as an early warning system for the problem.

特德。埃尔萨瑟，他是美国农科所的科学家，他的研究方向就是动物焦虑的征兆，他说，改变了的蛋白质即硝化蛋白对预防该问题有很大帮助。

One was that one molecule of nitrous acid di-rectly reacted with DMA,and the other was that two molecules of nitrous acid reacted first to yield nitrogen trioxide,which then reacted with DMA.

计算结果表明，DMA与亚硝酸间接反应的活化能比直接反应的低约55kJ/mol，由此可推断DMA与亚硝酸生成NDMA的反应是以两分子的亚硝酸先生成ONNO2再亚硝化DMA为主要反应途径。

Microcosm study of surface water from the stream showed that no significant change in NH4-N and NO3-N concentrations occurred during the five-day incubations.

各采样点的NO2-N、DO、DOC浓度与NO3-N也存在一定的线性相关关系，说明了硝化过程的发生和氮在不同形态之间的转化。
