During the study of Solid Rocket Ramjet, ablation of afterburner thermal insulation is a serious problem, which cannot be ignored.

固冲发动机补燃室绝热层的烧蚀问题是目前固冲发动机研制过程中所面临的一个重要问题。

The influence of afterburning chamber length on secondary combustion efficiency and flow field were analyzed based on direct-connected ground simulation test.

结合直连式地面模拟试验，分析了补燃室长度对掺混流场和二次燃烧效率的影响。

The cogeneration system is composed of boiler by waste heat, boiler for complemental burning and steam generator.

该系统主要由窑尾余热锅炉、补燃锅炉和汽轮发电机组成。

And the author considered the technology of cogeneration with boiler for complemental buring is mature, if the cement plant has supply of faulty coal, it is feasible to build a system of cogeneration with boiler for complemental burning, and it accord with the national energy source policy.

认为带补燃锅炉的余热发电技术是成熟的，只要水泥企业有劣质燃料供应，建设一套带补燃锅炉的余热发电系统是可行的，且符合国家能源政策。

In some extent, increasing the area of fuel nozzle will be improve the combustion efficiency of DR; 3, the angle between dual air-inlets have complex influence with the combustion of DR.

研究结果表明：(1)补燃室头部距离的增加能增强补燃室头部回流以及提高燃料在补燃室后段分布的均匀性，但也减少了燃料与空气在补燃室后段进行掺混和燃烧的长度：(2)在一定范围内，增加一次燃气喷嘴面积能提高冲压发动机燃料的燃烧效率：(3)进气道夹角对冲压发动机中燃料的燃烧影响复杂，对于采用对称结构喷嘴的冲压发动机，当进气道夹角等于180°时，燃料与空气的掺混效果最好；而对于一次燃气喷嘴采用不同偏心结构的冲压发动机，补燃室内流场与燃料燃烧效率随进气道夹角变化的规律基本相似。

Some conclusions are followed:(1)the reaction ratio of boron is 12% in primary combustion;(2)the degree of agglomeration can be decreased adopting boron coated with AP;(3)the content of oxygen is very important for afterburning efficiency;(4)the afterburning efficiency will be changed with different air-gas ratio;(5)the head distance of after-burning chamber is increasing, the circumfluence in the head of after-burning chamber is stronger and the distribution of fuel backward the after-burning chamber is more well-proportioned.(6)the combustion efficiency of DR will be improved by increasing the area of fuel nozzle.(7)the angle between dual air-inlets have complex influence with the combustion of DR.

通过本项研究，取得如下结论：（1）一次燃烧硼反应比例在12～15％之间；（2）AP包覆硼，可以降低硼结团度，有利于一次燃烧喷射效率的提高，也有利于硼在补燃室进行二次燃烧；（3）进气空气中的氧含量对二次燃烧非常重要；（4）对于一定配方的含硼富燃推进剂，不同的空燃比，二次燃烧效率不同；（5）补燃室头部距离的增加能增强补燃室头部回流以及提高燃料在补燃室后段分布的均匀性；（6）在一定范围内，增加一次燃气喷嘴面积能提高冲压发动机燃料的燃烧效率；（7）进气道夹角对补燃室内燃料的燃烧影响复杂。

According to thermodynamic basic theory, the expression of the gas turbine circulation thermal efficiency to coupling parameter on the premise of considering actual influence factor and the matrix form of steam turbine thermal efficiency with the unfired HRSG is strictly deduced through mathematics method .

根据热力学的基本理论，通过严格的数学推导，分别推导出考虑实际影响因素的燃气轮机实际循环热效率关于耦合参数的关系式，非补燃式余热锅炉型蒸汽轮机热效率的矩阵形式的关系式，最后得出了燃气-蒸汽联合循环热效率关于耦合参数的关系式。

It is a key technique for ducted rocket to make the second combustor operate at high efficiency and stability.

然而补燃室内燃气同空气的掺混燃烧过程十分复杂，影响燃烧效率的设计参数很多。

As the major direction of the propulsion system for supersonic missile, the ducted rocket has good prospects.

实现补燃室高效率、稳定、可靠的工作，是固体火箭冲压发动机的关键技术问题。

The model is used to simulate the three-dimensional combustion flowfields in an experimental motor.

通过计算与分析，增进了对补燃室内掺混燃烧过程的理解，为固体火箭冲压发动机补燃室设计提供了一些有意义的结果：1。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
