Using this theory, the flame structure of gas explosion in a horizontal pipe were studied, and the results show that: the gas explosion flame in a horizontal pipe is much thicker than that calculated from the former explosion theory, the intermediate products in the flame region are in separated state between the higher and lower level, and the cohesive force of the luminous body at lower level is bigger than that of the nonluminous body at higher level, there is a negative pressure region in the flame, and the flame splits easily in its propagating process.

结果表明，a水平管道内瓦斯爆炸传播火焰的厚度比以往理论计算得到的厚度大得多；b火焰区内爆炸中间产物呈上下分离状态，下部明亮发光体的内聚力比上部非发光体的内聚力高；c在火焰区内会出现负压现象；d火焰在传播过程中会发生断裂现象。

The results showed that the blending system could form surface gel and internal spumescent char layer to achieve flame retardant properties.The flame retardant properties of flame resistant PA6 contenting TPMP/MA complex system were studied by LOI,UL-94 and cone calorimeter tests.The results showed that the LOI value of PA6/17%MA system was 27.2,and the LOI value of PA6/4%TPMP/13%MA system was 28.6.The UL-94 test was V-0 level.The flame retardant mechanism analysis indicated that the TPMP/MA complex system could form thick intumescent char layer to execute the flame retardant functions both in the condensation phase and the gas phase.

将阻燃剂TPMP、MA复配后添加到PA6中，通过采用LOI、垂直燃烧及锥型量热仪研究了体系的阻燃性能，PA6/17%MA体系的LOI值为27.2，PA6/4%TPMP/13%MA体系的LOI值达到了28.6；上述体系的垂直燃烧性均为V-0级，对阻燃机理的分析表明，TPMP与MA复配应用时，可形成膨胀的较厚炭层，在气相和凝固相共同发挥阻燃作用。

In the experimentation, the premixed propane-air flame propagation behavior was studied as the following:(1) Study on pressure wave influence on premixed propane-air flame propagation behavior under different pressure relief case The high speed Schlieren photograph method was used to record the dynamic process of flame propagation clearly, including the precise flame front position, flame structure, and so on.

实验过程中，首先利用预混火焰精细实验台对丙烷-空气预混火焰的传播特性进行了实验研究：(1)重点研究了不同泄压条件下的压力波对丙烷-空气预混火焰传播特性的影响。

Process:① the platinum wire dipped in concentrated hydrochloric acid to colorless colorless flame on the ignition;②sample in the colorless flame ignition, to observe the flame color (if test potassium cobalt glass through observation, because in most cases need to be used when the system of potassium sodium, potassium solution, therefore often contain sodium, and sodium yellow flame color reaction, a small amount of yellow and purple, respectively, can not come out).

3操作过程：①将铂丝蘸浓盐酸在无色火焰上灼烧至无色；②蘸取试样在无色火焰上灼烧，观察火焰颜色(若检验钾要透过钴玻璃观察，因为大多数情况下制钾时需要用到钠，因此钾离子溶液中常含有钠离子，而钠的焰色反应为黄色，黄色与少量的紫色无法分别出来)。

The results show that the liftoff height of the CH4/Air jet flame decreases with the increase of the coflow temperature, and the change of the liftoff height versus the coflow temperature presents the twostages behavior, and the stabilization of lifted flame is dominated by the autoignition of premixed homogeneous mixture in lower coflow temperature range. The phenomena of rapid multipoint autoignition were observed in the experiment of diesel fuel spray issuing into the CATA, and a special lifted flame appeared with a triple flame.
