難燃劑
英文
flame retardant-
The faa requires that an arff fire fighter have a monthly training regiment that consist of airport familiarization, aircraft familiarization, rescue and fire fighting personnel safety, emergency communications systems on the airport, use and training of specialized apparatus and appliances required to do their job, application of the types of extinguishing agents required to suppress aircraft fires, emergency aircraft evacuation assistance, fire operation, adapting and using structural rescue and fire fighting equipment for aircraft rescue and fire fighting, aircraft cargo hazards, and familiarization with fire fighters duties under the airport emergency plan
美國聯邦航空局要求飛機救援消防的消防員每月接受的培訓內容包括熟悉機場，熟悉飛機，救援與消防人員的安全問題，機場應急通信系統，消防工作中所需掌握的特殊器具的使用與培訓，抑制飛機燃燒的滅火劑類型的應用，飛機緊急情況下的疏散協助，滅火操作，使用建築物救火設施進行飛機救難和消防工作，飛機危險貨品，以及熟悉在機場應急計劃中消防員的職責。( 9 ) by studying matching between catalytic converter and exhaust gas system, the conclusions having been gotten as follow : " purifying step by step and driving step by step " and " mental substrate and chinaware substrate being used in same engine " being the laying principles in exhaust gas system, which can solve the contradiction between high converting efficiency of exhaust emission and small loss of power, fuel economics, the rapid light - off and laying difficulty of catalyst
（ 9 ）進行了催化轉化器與排氣系統的匹配研究，對于催化劑的布置，提出了「分級凈化，逐級推動」的原則；對于載體形式的選擇，提出了「金屬載體和陶瓷載體復合」使用的原則。這樣可以良好的解訣催化轉化器與發動機匹配時，排氣污染物高凈化率與動力性經濟性損失小之間的矛盾、快速起燃和結構布置困難的矛盾。Unfortunately, the solid propellants ? usually aluminum fuel and ammonium perchlorate oxidizer ? burn fairly inefficiently, are toxic to the environment, and are difficult to fabricate and handle safely
然而固體推進劑（通常是鋁燃料和過氯酸銨氧化劑）燃燒效率頗低、對環境有害，而且很難安全地製造和操作。It is very difficult to research the burning characteristic of high energy propellant in the ddt pipe applying the ionization probe. but the satisfactory results can be easily got using photoelectricity triode
用探針法研究ddt管中高能推進劑的燃燒波和爆轟波的傳播特性，因各種因素的影響難以得到滿意的結果，用光電三極體代替電離探針可得到相對理想的結果。The simulations results show that the spoiler is available to make the fuel and the oxidizer coming from the former to stay in the cavity for a long time, to let the fuel and oxidizer mix and burn completely. since there is a high temperature zone forming by vortex in the middle of the motor, it required a restricted thermal protection. the plate with holes decreased the vortex function in the cavity, which could not promote the combustion efficiency, but to decrease temperature in the cavity and be benefit to thermal protection of the wall
計算結果分析表明:擾流板可以使燃料和氧化劑在擾流腔內的滯留時間加長，促進燃料與氧化劑的摻混燃燒，提高燃燒效率，但由於渦流在發動機的中間部位形成了高溫燃燒區域，致使局部燃料和絕熱層燒蝕速率增大，加大了熱防護的難度;孔板結構減弱了擾流腔內迴流區的漩流作用，不能增加推進劑燃燒效率，但可以使擾流腔內的溫度降低，給壁面熱防護帶來好處。We are not using pbb, pbb0 in all manufacturing process of actuator unit
本產品從原材料到成品裝配的整個製造過程中，一概沒有使用溴化物難燃劑。The chemical reactions in the flame area are very complex. it is very difficult to measure the number density distribution of the particles ( atoms, ions and molecules ), so the relative intensity method is employed
由於固體推進劑燃燒區內發生的化學反應非常復雜，直接測量火焰區內的粒子（原子、離子以及分子等）數密度比較困難，因此選用相對強度法來進行計算。Liquid propellant combustion processes are quite complicated and defy precise analytical description.
液體推進劑燃燒過程是相當復雜的，很難對其進行嚴謹的分析描述。分享友人
