硝化器

With singular attention to detail, the new Eric Johnson Stratocaster RW features a two-piece alder body finished in thin-skin nitrocellulose lacquer, a quartersawn maple neck with bound round-laminated 12-radius rosewood fretboard, a three-ply parchment pickguard, pickups voiced by Johnson himself, staggered vintage-style tuners, a custom tremolo block, and four brand-new finish options, three of which (Lucerne Aqua Firemist, Tropical Turquoise and Medium Palomino Metallic) are exclusive to this model.

对细节独到的关注，新的签名琴的特点是琴体由两片赤杨木组成并由硝化纤维清漆粘和；琴颈为quartersawn枫木，与12英寸半径的桃花芯木指板粘和组成；外带3层羊皮纸的匹克护板；拾音器由埃里克约翰逊亲自参与设计制作；直排复古型卷线器；以及订制级颤音摇把；4款全新的颜色选择，其中3个（网页上有：深蓝色，浅蓝色和金棕色）都是这一款琴独有的。

In this paper, the thermochemistry and thermodynamics parameters of semi-batch reaction were measured by adding toluene into the reactor filled with mixed acid, which can be used for safer operation design.

混酸条件下的甲苯硝化是一个典型的液-液两相反应，本文主要通过自动化实验室反应量热器测试了向混酸中滴加甲苯这一半间歇硝化过程中的热化学和动力学数据，从而进行反应过程的安全性研究。

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。

Firstly, micro-thermal calorimeters were used to qualitatively analyze the thermochemistry behaviour of reactants system under adiabatic mode; Subsequently a series of toluene nitration experiments were carried out in an isothermal reaction calorimeter to study the influences of different operating conditions such as stirring speed feeding rate and setting temperature and so on . The thermal hazard assessment of toluene nitration was derived from the measured calorimetric data, the rate of the reaction the adiabatic temperature increase △T_ad and maximal temperature attainable MTSR_max in a runaway situation can also been derived.

首先采用微量热分析仪对反应体系在绝热状态下的热行为进行分析；再采用等温条件下的反应量热器实验研究不同的工艺条件如搅拌速度、加料速度和设定温度等参数对反应结果的影响；结合热分析数据和RCle数据，对甲苯的一段硝化过程进行了初步的热危险分析，推导出反应速率方程、反应失控条件下的绝热温升△T_和反应所能达到的最大温度MTSR等参数。
